🎯 What is a Google Core Update?
"Core Updates are Google's way of ensuring that search results are as helpful as possible to users, prioritizing content that meets their needs." – *From Google's official documentation.*
📊 Definition and Goal
🔄 A **Google Core Update** is a major update to the main search engine algorithm that periodically reviews and re-evaluates the quality of content on the internet. Unlike targeted updates, such as the Spam Update 🚫 or the Product Review Update ⭐, which focus on specific violations or content types, Core Updates are **global** in nature 🌍.
📊 They affect the ranking of millions of pages, assessing them based on criteria such as **relevance, usefulness, trustworthiness, and user experience**. In 2025, these updates became more technologically advanced thanks to the integration of **artificial intelligence** 🤖, specifically the MUVERA algorithm, which analyzes content uniqueness with 90% greater accuracy than previous methods, and the Graph Foundation Model (GFM), which improves the evaluation of connections between pages by 40 times.
🎯 The **goal** of Core Updates is to ensure that users receive the most relevant and valuable information in response to their queries. For example, if you are looking for health advice 🏥, Google aims to show articles from **authoritative sources**, such as medical sites with confirmed experts, rather than blogs with unverified claims. These updates do not "punish" sites for violations but **redistribute positions** in the search results (SERP), favoring resources that comply with the **E-E-A-T** principles 🏆.
✅ Key Features of Core Updates
- 🌍 **Global Impact:** Core Updates affect all aspects of Google Search, including web search, images, video, Google News, Discover, and even AI Overviews (short, AI-generated answers at the top of the results page).
- 📈 **Content Reassessment:** The algorithm does not focus on individual sites but compares them with competitors, boosting the positions of those that offer more relevant and useful content.
- 🕒 **Frequency and Duration:** Google conducts Core Updates **3–4 times a year**, with each update rolling out over **1–3 weeks**, causing temporary volatility in search results.
- 🤖 **AI Technologies:** In 2025, Core Updates use advanced tools like **MUVERA** for detecting duplicate or low-quality content and **GFM** for analyzing contextual links between pages.
👉 Practical Examples of Impact
📉 A health website 🏥 that lost traffic after an update may have suffered due to **weak E-E-A-T**. For example, if articles lack authors with medical education 👨⚕️ or refer to unreliable sources, Google may demote them in favor of sites with **verified expertise**, such as WebMD. Another example is an e-commerce store 🛒 with a poor mobile version, which lost positions due to **slow loading speed** ⚡.
⚡ **Important:** Google emphasizes that losing positions after a Core Update does not always mean there is a problem with the site. Sometimes, it is the result of competitors creating **better content** 📈 or better meeting user needs. Instead of rushing "fixes," Google recommends focusing on **content quality** and waiting for the next update to assess changes, as effects may only stabilize after several months 📅.
🎯 Core Updates also affect niches with high standards for trustworthiness, known as **YMYL** (Your Money or Your Life – health 🏥, finance 💰, education 📚). For such topics, Google applies particularly strict E-E-A-T standards 🏆 to protect users from misinformation. For example, a financial blog without transparent information about authors or sources may lose visibility, while a site with certified analysts will gain an advantage.
✅ **Quick Conclusion:** A Google Core Update is a tool for improving search, which stimulates the creation of **high-quality, trustworthy, and user-centric content** using advanced AI technologies 🤖 for assessment.

🔬 How Do Core Updates Work?
"Core Updates review the web to ensure the best experience for users, evaluating content based on criteria of quality and relevance." – *Inspired by Google's official documentation.*
📊 Mechanics of Core Updates
🔄 **Google Core Updates** are complex search engine algorithm updates that analyze the entire web to determine which pages best answer user queries. During a Core Update, the Google algorithm re-evaluates content based on several key criteria, including **E-E-A-T** 🏆 (Experience, Expertise, Authoritativeness, Trustworthiness). This means Google checks how relevant, useful, original, and positive the user experience the content provides. In 2025, the focus intensified on the use of **artificial intelligence** 🤖, specifically technologies like **MUVERA**, which accelerates the analysis of content uniqueness by 90%, and the **Graph Foundation Model (GFM)**, which improves the evaluation of links between pages with 40 times greater accuracy than previous methods.
📊 Core Updates are not aimed at specific sites or violations, such as the Spam Update 🚫, but **redistribute positions** in the search results (SERP) by comparing sites based on their value to users. For example, if two sites offer articles about "healthy eating" 🥗, Google will favor the one with a clear structure, verified sources, and fast loading on mobile devices 📱. In 2025, Google also increased its focus on recognizing **AI-generated content**. Sites using automatically generated texts without proper editing may lose positions because Google is better at detecting low-quality or templated material.
- ✅ **Point 1: E-E-A-T Assessment:** Google checks whether the site demonstrates **experience and expertise** (e.g., whether authors have appropriate qualifications), **authoritativeness** (links to reliable sources), and **trustworthiness** (transparency of site information).
- ✅ **Point 2: User Experience:** The algorithm analyzes technical aspects, such as **loading speed** (according to Core Web Vitals standards), **mobile adaptation**, and ease of navigation.
- ✅ **Point 3: Impact on All Surfaces:** Core Updates affect not only web search but also Google News, Discover, images, video, and AI Overviews generated by artificial intelligence.
- ✅ **Point 4: Volatility:** During the rollout (1–3 weeks), site positions may fluctuate, requiring patience and analysis from SEO specialists.
👉 **Example:** A recipe site using generic AI-generated texts without unique insights lost 25% of traffic after the update due to low originality. In contrast, a blog with detailed recipes from a chef, featuring videos and user reviews, saw a 15% increase.
⚡ **Important:** Google does not disclose the details of the algorithm but officially states that improving content and user experience is the only way to recover positions. Attempts to "bypass" the algorithm through excessive keyword optimization may worsen the situation.

💡 **Expert Tip:** Use tools like Google Search Console to track changes in traffic and positions after a Core Update. This will help you understand which aspects of your site need improvement.
✅ **Quick Conclusion:** Core Updates act as a comprehensive "quality check," emphasizing **E-E-A-T**, user experience, and **AI-analytics**, making SEO in 2025 more focused on creating value for people.

💡 History of Core Updates with a Focus on 2025
"Every Google Core Update is a step towards a smarter and more useful search that adapts to changes in user behavior and technology." – *Inspired by Google's statements.*
📊 Evolution of Core Updates: From Simple Algorithms to AI Systems
🔄 Google Core Updates began to be implemented regularly in the 2010s, when the primary focus was on basic content relevance to search queries. For example, the Panda Update 🐼 (2011) fought against low-quality content, and Penguin 🐧 (2012) penalized manipulative links. Over the years, algorithms have become more complex, integrating **machine learning** and **artificial intelligence**. By 2025, Core Updates have transformed into AI-oriented systems that use advanced technologies like **MUVERA** for analyzing content uniqueness and the **Graph Foundation Model (GFM)** for evaluating links between pages with 40 times greater accuracy than previous methods.
📈 Key stages of evolution up to 2025 include:
- 🏆 **2018–2019:** Introduction of the **E-A-T** (Expertise, Authoritativeness, Trustworthiness) concept, especially for YMYL topics 🏥💰📚.
- 🤝 **2022–2023:** Launch of the **Helpful Content Update**, which promoted content created for people, not search engines.
- ⚡ **March 2024:** Integration of the Helpful Content Update into the core algorithm, intensifying the focus on content usefulness.
- 📱 **December 2024:** An update focusing on **user experience**, including loading speed and mobile adaptation.
🎯 In 2025, Google continued this course, releasing two major Core Updates (March and June) and a Spam Update (August). These updates emphasized the priority of **content quality, trustworthiness, and AI-analytics** 🤖, which changed approaches to SEO.
✅ Advantages of Core Update Evolution
- ✅ **Better Search Relevance:** Thanks to AI technologies like GFM, Google more accurately determines user intent, showing results that better match queries.
- ✅ **Stimulating Original Content:** Sites with unique, well-structured materials receive higher rankings, motivating the creation of valuable content.
- ✅ **Integration of Advanced Technologies:** MUVERA and GFM allow Google to detect duplicate content faster and evaluate site authority, improving SERP quality.
- ✅ **Improved User Experience:** The focus on mobile optimization and loading speed makes sites more user-friendly, especially for the 60%+ of searches from mobile devices.
❌ Disadvantages of Core Update Evolution
- ❌ **SERP Volatility:** Ranking changes can last for weeks, complicating SEO strategy planning and traffic forecasting.
- ❌ **Traffic Loss for Sites without Strong E-E-A-T:** Resources without verified expertise (especially in YMYL topics) can lose up to 30–50% of organic traffic.
- ❌ **Delays in Assessing Effects:** The full impact of a Core Update may only become apparent after several months, forcing site owners to wait for the next update to recover.
- ❌ **Difficulty in Adaptation:** High requirements for E-E-A-T and technical optimization demand significant resources, which can be a challenge for small sites.
👉 **Example:** After the June 2025 Core Update, a financial blog with articles from certified analysts and transparent sources saw a 25% traffic increase, while a competitor with generic AI-generated articles lost 40% of visibility due to weak E-E-A-T.
⚡ **Important:** Google does not provide clear instructions on "fixing" losses after a Core Update but advises focusing on creating content for people and improving the technical aspects of the site. Attempts at quick manipulations, such as mass keyword or link addition, may worsen the situation.
💡 **Expert Tip:** Use monitoring tools like SEMRush, Ahrefs, or Google Search Console to track volatility after Core Updates. This will help identify problematic pages and assess the impact of changes in real-time.
✅ **Quick Conclusion:** The 2025 Core Updates are the culmination of Google's algorithm evolution, combining AI technologies and a focus on content quality, requiring SEO specialists to be adaptable and strategic.

🎯 Google March Core Update 2025
"The March 2025 Core Update was the first step towards enhancing search quality, with an emphasis on fighting spam and promoting trustworthy content." – *Inspired by Google's official announcement.*
📊 Deployment Details and Key Changes
📅 The Google **March 2025 Core Update** was launched on March 13 and completed on March 27, lasting exactly two weeks. According to estimates from the SEMRush monitoring tool, it caused moderate volatility in the search results (SERP) at a level of **7.8/10**, which is lower than the later June update but still significant for many sites. The main focus of the update was on **YMYL** topics 🏥💰📚 (Your Money or Your Life – health, finance, education), where Google tightened the requirements for **E-E-A-T** 🏆 (Experience, Expertise, Authoritativeness, Trustworthiness). This update served as a preparatory stage for the larger June Core Update, laying the foundation for improving algorithms and fighting low-quality content.
🔄 The March update integrated data from previous updates, including the Helpful Content Update (March 2024), which emphasized creating content for people, not search engines. It also intensified the fight against **spam** 🚫, reducing the visibility of sites with "**thin**" content – short, uninformative articles or pages overloaded with keywords without real value. Many sites, especially in the health and finance niches, noted an improvement in the relevance of search results, but the full effect only became apparent a few weeks after the rollout was complete.
- ✅ **Point 1: Enhanced E-E-A-T:** Google increased the requirements for demonstrating expertise, especially for YMYL topics. Sites with authors who have verified qualifications (e.g., doctors, financial analysts) gained a ranking advantage.
- ✅ **Point 2: Reduced Visibility of Thin Content:** Pages with superficial information, duplicate material, or excessive SEO optimization lost positions in favor of higher-quality resources.
- ✅ **Point 3: Integration of Previous Data:** The update used data from the 2024 Helpful Content Update to better assess content usefulness, which helped promote sites with deep, well-structured materials.
- ✅ **Point 4: Focus on YMYL Topics:** In niches related to health, finance, and education, Google intensified the verification of source credibility and author transparency.
👉 **📈 Example:** A medical blog 🏥 that published articles by doctors 👨⚕️, specifying their qualifications and referencing scientific sources, saw a 20% increase in organic traffic after the March update. In contrast, a competing site with generic articles lacking authorship lost 15% of visibility due to weak E-E-A-T. Another example – a financial portal 💰 that added expert biographies and an "About Us" page rose 10 positions in the SERP for key queries.
⚡ **Important:** Google officially states that there are no specific "fixes" for recovering positions after a Core Update. Instead, site owners should focus on the **overall quality of content**: its depth, originality, and alignment with user needs. Attempts at quick manipulations, such as mass addition of keywords or links, may lead to further losses. Google also recommends waiting for the next update, as ranking changes may only stabilize after several months 📅.
🔄 The March update also paved the way for the implementation of new technologies in the June Core Update. For example, the algorithm began to actively use **user behavior data** 👥 (time on page, bounce rate) and **technical indicators** ⚡ (loading speed, mobile adaptation), which became the basis for more significant changes in 2025.
💡 **Expert Tip:** After the March update, conduct a content audit using Google Search Console and PageSpeed Insights to identify pages with low performance or weak E-E-A-T. This will help prepare for subsequent updates.
✅ **Quick Conclusion:** The Google March 2025 Core Update emphasized the importance of **trustworthiness and content quality**, serving as a preparatory stage for the more technological June update.

🔬 Google June Core Update 2025
"The June 2025 Core Update became one of the largest in recent times, causing significant volatility in search results and partial recoveries for sites affected by previous updates." – *Inspired by Google's statements and Search Engine Land analysis.*
📊 Deployment Details and Key Features
📅 The Google **June 2025 Core Update** was officially launched on June 30, 2025, at 07:30 Pacific Time (PT), making it the second major Core Update of the year after the March update. The rollout lasted **16 days and 18 hours**, concluding on July 17, 2025. According to monitoring tools like SEMRush, volatility reached a record level of **9.3/10** 🌊, making this update one of the most influential in recent years.
🌍 The update affected global search results, covering all languages and regions, with particularly strong effects in **YMYL** niches 🏥💰📚 (Your Money or Your Life – health, finance, education), news 📰, shopping 🛒, and finance. It caused waves of fluctuations: the first immediately after the announcement, the second from July 8 to 10, and a third even after the conclusion, with effects continuing until the end of July.
🤖 Although Google did not disclose technical details, analysts attribute the update to the implementation of advanced **AI technologies**: **MUVERA**, which accelerates the search for similar content by 90%, helping to detect duplicate or low-quality material, and the **Graph Foundation Model (GFM)**, which improves the analysis of links between pages with 40 times higher accuracy. This intensified the focus on **uniqueness, trustworthiness, and user experience**, with an emphasis on **AI Overviews**, which impacted the click-through rate of organic results.
- ✅ **Point 1: High Volatility:** Fluctuations in the SERP peaked on July 11–14, impacting all Google surfaces – web, images, video, News, Discover, and AI Overviews.
- ✅ **Point 2: Partial Recoveries:** Sites affected by previous updates (e.g., Helpful Content Update 2023) saw a 20–50% increase in visibility if they had improved their **E-E-A-T**.
- ✅ **Point 3: Impact on YMYL Niches:** Significant changes in health, finance, and education; sites with strong expertise (authors with qualifications) won, while those with AI-generated content lost.
- ✅ **Point 4: Rise of Zero-Click Results:** AI Overviews reduced clicks to sites by 10–15%, especially in news and shopping.
👉 **Example:** A financial portal that updated its articles with biographies of certified analysts and links to authoritative sources saw a **30% increase** in organic traffic after the update. Conversely, a news site with unedited AI-generated articles lost 40% of visibility due to low uniqueness, as detected by MUVERA. Another case – a medical resource that recovered from the March setback by **25%** by adding videos and interactive elements for a better user experience.
⚡ **Important:** Google emphasizes there are no "**quick fixes**" for losses – focus on a long-term strategy: improving content, **E-E-A-T**, and technical optimization. Volatility can last for weeks, so monitor data in Google Search Console, but avoid panicking over short-term fluctuations.

💡 Other Google Updates in 2025
"In addition to Core Updates, Google continued to clean up the search space in 2025, fighting spam and improving algorithms to ensure quality results." – *Inspired by Google's statements.*
📊 Overview of Other 2025 Updates
📅 In 2025, besides the two massive Core Updates (March and June), Google also conducted several other updates that impacted search results (SERP) and SEO strategies. The most notable was the **August Spam Update** 🚫, launched on August 26, 2025, and completed after **26 days and 15 hours**, making it one of the longest updates of its kind. It targeted manipulative practices such as spam links, low-quality automatically generated content 🤖, and sites violating Google's policies.
🔍 Furthermore, the SEO community actively discussed speculations about an **unconfirmed update in October 2025**, which might have affected **AI Overviews** and certain niches, especially **YMYL** 🏥💰📚 (Your Money or Your Life – health, finance, education). However, as of October 24, 2025, Google has not confirmed any official update in October, leaving these changes at the rumor level.
⚡ The August Spam Update was an important complement to the Core Updates, as it focused on cleaning up the search space from low-quality sites using "black" or "gray" SEO methods. This update affected sites that had previously avoided sanctions but had weak quality signals. At the same time, the speculative October update, according to monitoring tools, caused **local volatility** in niches related to news 📰, shopping 🛒, and **AI Overviews**, where short, AI-generated answers began to take up more space in the SERP.
- ✅ **Point 1: August Spam Update:** A long-duration update (26 days 15 hours) focused on detecting and reducing the visibility of sites with manipulative practices, including automatically generated content without human editing.
- ✅ **Point 2: Unconfirmed October Update:** Speculations about changes in AI Overviews and YMYL topics, with volatility in news and commercial queries, but no official confirmation from Google.
- ✅ **Point 3: Impact on SEO:** The updates reinforced the importance of adhering to Google's policies, particularly avoiding spam techniques and focusing on content quality.
- ✅ **Point 4: Synergy with Core Updates:** The August update complemented the March and June updates, reinforcing the emphasis on **E-E-A-T** (Experience, Expertise, Authoritativeness, Trustworthiness) and user experience.
👉 **Example:** An online store that used automatically generated product descriptions with excessive keywords lost **35%** of organic traffic after the August Spam Update. Conversely, a competitor who invested in unique descriptions and user reviews saw a 15% increase. In October 2025, a news blog noticed a decline in clicks due to the expansion of **AI Overviews**, which provided answers directly in the SERP, reducing the need to visit the site.
⚡ **Important:** Speculations about the October update should not lead to rushed changes on the site. Google advises relying only on official announcements and focusing on creating quality content, rather than reacting to rumors that may result from temporary fluctuations.
✅ Advantages of Other Updates
- ✅ **Cleaner Search Space:** The August Spam Update reduced the visibility of sites with manipulative practices, which increased the quality of search results for users.
- ✅ **Better Spam Protection:** Google improved algorithms for detecting low-quality content, reducing the impact of spam sites on SERP competition.
- ✅ **Opportunity for Quality Sites:** Resources with high **E-E-A-T** and compliance with Google policy gained a chance to occupy higher positions after the search results were cleaned up.
- ✅ **Improved AI Overviews:** Potential changes in October (if confirmed) contribute to the accuracy of short answers, which is useful for informational queries.
❌ Disadvantages of Other Updates
- ❌ **Uncertainty from Speculation:** Rumors about the October update create panic among SEO specialists, complicating strategy planning.
- ❌ **Long Periods of Volatility:** The August Spam Update lasted almost a month, causing prolonged fluctuations in ranking.
- ❌ **Requirements for Constant Monitoring:** Site owners are forced to regularly check data in Google Search Console and tools like SEMRush to track the impact of updates.
- ❌ **Risk for Small Sites:** Smaller resources without significant SEO budgets may suffer from increased quality requirements.
💡 **Expert Tip:** Follow official Google announcements via the Google Search Central blog or the @searchliaison Twitter account to avoid panicking over rumors of unconfirmed updates. For the August Spam Update, check your site's compliance with Google policy using the Lighthouse tool.
✅ **Quick Conclusion:** The August Spam Update and potential changes in October 2025 supplemented the Core Updates, intensifying the fight against spam and emphasizing the importance of quality content, but added challenges due to volatility and rumors.

📊 Winners and Losers: Who Gained and Who Suffered
🎯 The Core Updates of 2025, particularly the March and June updates, caused significant changes in the search results (SERP), affecting the ranking of sites worldwide. These updates, reinforced by new **AI technologies** 🤖 such as MUVERA and the Graph Foundation Model (GFM), intensified the focus on **E-E-A-T** 🏆 (Experience, Expertise, Authoritativeness, Trustworthiness), user experience, and technical optimization.
📊 **Winners:** ✅ Sites that invested in **original, in-depth content**, demonstrated strong **E-E-A-T**, and had **flawless mobile optimization** 📱 saw significant growth in traffic and visibility. For example, resources with expert authors 👨💼, transparent sources, and fast page loading won the competitive battle.
📉 **Losers:** ❌ Sites with "**thin**" content (superficial articles, keyword-stuffed), excessive advertising, or **AI-generated texts without human editing** 🤖 suffered significant losses. The impact on **YMYL** topics 🏥💰📚 was particularly severe: sites without verified expertise lost up to **50%** of organic traffic.
🤖 The updates also strengthened the role of **AI Overviews** – short, AI-generated answers that appear at the top of the SERP. This led to a **10–15%** reduction in the click-through rate of organic results in some niches, such as news 📰 and commercial queries 🛒. At the same time, sites that appeared in AI Overviews due to structured content gained additional visibility.
- ✅ **Point 1: Traffic Growth for Niche Sites:** Local and thematic resources with **unique content** and a clear target audience (e.g., healthy eating or financial planning blogs) saw traffic increases of **20–40%**.
- ✅ **Point 2: Losses for Unoptimized Mobile Versions:** Sites with slow loading or poor design on smartphones (over 60% of searches in 2025 are mobile) lost up to **30%** visibility.
- ✅ **Point 3: Reinforced Role of AI Overviews:** AI answers reduced clicks on organic results, but sites with clear, structured answers to popular queries gained a chance to appear in these blocks.
- ✅ **Point 4: Impact on YMYL Topics:** Sites with verified expertise (authors with qualifications, transparent sources) gained an advantage, while resources with unedited AI texts suffered significant losses.
👉 **Example:** A financial portal that hired certified analysts to create detailed articles on investments and added author biographies increased visibility by **30%** after the June Core Update. Conversely, a competing site with short, AI-generated articles lacking sources lost **45%** of traffic due to weak E-E-A-T. Another example – a medical blog that added interactive tools (calorie calculators) and videos from doctors recovered **25%** of lost traffic from previous updates.
⚡ **Important:** Analyzing competitors using tools like Ahrefs or SEMRush is key to understanding changes in the SERP. Studying the sites that benefited from the update will help identify successful strategies – from content structure to backlink profile.

🔬 Practical SEO Adaptation Strategies for Core Updates 2025
"Success in SEO after the Core Updates 2025 depends on creating content for people, not for algorithms, with a clear focus on E-E-A-T and technical optimization." – *Inspired by Google's recommendations.*
📊 How to Adapt Your Site to Google's New Standards
🎯 The Core Updates of 2025, especially the March and June updates, highlighted the importance of creating **high-quality, user-centric content** that adheres to the **E-E-A-T** 🏆 (Experience, Expertise, Authoritativeness, Trustworthiness) principles. To adapt to Google's new standards, you need to focus on three key aspects: creating helpful content, improving E-E-A-T, and technical optimization, especially for mobile devices.
📱 In 2025, with over 60% of searches coming from smartphones and **AI technologies** 🤖 like MUVERA and the Graph Foundation Model (GFM) determining content uniqueness and links, these strategies are critically important for maintaining and growing positions in the search results (SERP).
💡 Google emphasizes that successful adaptation is not about quick "fixes" or manipulations, but about a **long-term strategy** that puts the user at the center 👥. This means creating detailed, structured articles with lists, tables, and interactive elements that satisfy the user's intent.
📊 Improving **E-E-A-T** through author biographies 👨💼, transparent sources, and credible information is crucial, especially for **YMYL** topics 🏥💰📚 (health, finance, education). **Technical optimization** ⚡, including loading speed (according to Core Web Vitals standards) and responsive design, also plays a decisive role in the post-update era.
- ✅ **Point 1: Create Content for People:** Write **in-depth articles** that answer specific user queries, using structured formats (headings, lists, tables) for easy reading and scanning.
- ✅ **Point 2: Improve E-E-A-T:** Add **author biographies** specifying their qualifications, link to authoritative sources, and provide transparent site information (e.g., "About Us," "Contact Us" pages).
- ✅ **Point 3: Mobile and Technical Optimization:** Check loading speed with Google PageSpeed Insights, ensure a **responsive design**, and avoid elements that degrade the experience on smartphones (e.g., pop-ups).
- ✅ **Point 4: Content Audit and Update:** Regularly review old pages, **delete or update** outdated or "thin" content, adding current information and interactive elements.
- ✅ **Point 5: Competitor Analysis:** Use tools like Ahrefs or SEMRush to study the strategies of sites that benefited from the updates, and adapt them to your resource.
👉 **Example:** A medical blog that added doctor biographies, links to scientific research, and an interactive calorie calculator increased organic traffic by **35%** after the June Core Update. Another example – an online store that optimized its mobile version according to PageSpeed Insights (reducing loading time from 5 to 2 seconds) recovered **20%** of lost traffic. Conversely, a site with outdated articles and aggressive advertising lost 40% of visibility due to low content quality.
⚡ **Important:** Google advises against rushed changes after losing positions – instead, conduct a **comprehensive site audit**, focusing on content quality and technical aspects. The results of improvements may only become apparent during the next Core Update, so plan your strategy for 3–6 months.

🚀 These strategies not only help adapt to Core Updates but also increase the overall competitiveness of the site. For example, adding **structured data** 🏷️ (schema markup) can improve the chances of appearing in AI Overviews, and regular content updates 🔄 ensure its relevance to users.
⚠️ It is important to avoid spam practices, such as buying links or excessive keyword optimization, as Google in 2025, thanks to MUVERA, is more effective at detecting 🤖 such manipulations.
💡 **Expert Tip:** Use Google Search Console to monitor Core Web Vitals metrics and user behavior (time on page, bounce rate). This will help identify weak points of the site and focus efforts on fixing them.
✅ **Quick Conclusion:** Regular site auditing, creating content for people, and focusing on **E-E-A-T** and technical optimization are the keys to success in SEO after the 2025 Core Updates.

❓ Frequently Asked Questions (FAQ)
🔍 How can I precisely determine which pages of my site were affected by the Core Update 2025?
📊 To find out if the update affected your site, use **Google Search Console** to analyze traffic, position, and click data for key queries. Compare metrics for 2–3 weeks before and after the deployment dates (March 13–27 and June 30 – July 17, 2025). Pay attention to pages with a **sharp drop in traffic** 📉 or click-through rate (CTR).
🛠️ Additionally, use tools like SEMRush or Ahrefs to identify changes in ranking for specific keywords. For example, if a page lost positions in **YMYL** topics 🏥💰📚, check if it meets the **E-E-A-T** 🏆 requirements (presence of qualified authors, trustworthy sources). Also, analyze behavioral metrics (time on page, bounce rate) in Google Analytics to pinpoint weaknesses in content or user experience.
🔍 Can a site recover its positions without the next Core Update?
🔄 Recovering positions between Core Updates is possible, but usually limited. Google states that the algorithm constantly re-evaluates content, but significant ranking changes most often occur during the next Core Update.
🎯 To increase the chances of recovery, focus on improving **E-E-A-T**: add **author biographies** 👨💼 specifying their expertise, update outdated content, and delete "**thin**" pages (with low value). For example, a financial site can add articles from certified analysts and links to official sources.
⚡ Technical optimization, such as reducing loading time according to Core Web Vitals standards, can also yield quick results. However, avoid making mass changes, such as rewriting all pages, as this can cause additional volatility.
🔍 How to use AI-generated content without getting penalized by Google?
🤖 Google does not prohibit **AI-generated content**, but in 2025, thanks to MUVERA technology, it is more effective at detecting low-quality or templated texts. To avoid loss of visibility, every AI-generated material requires **thorough editing** ✍️. Add unique insights, real-world examples, and data from authoritative sources.
🏆 For example, in **YMYL** topics 🏥💰, articles must have clear **authorship** 👨💼 (expert with qualifications) and verified facts. Use AI as a drafting tool, but rewrite it to comply with the **people-first content** 👥 principle. Also, structure the content with headings, lists, and tables to facilitate user comprehension and increase the chance of appearing in AI Overviews.
🔍 How do AI Overviews affect organic traffic and how can I appear in them?
📊 **AI Overviews**, which appear at the top of the SERP, reduced clicks on organic results by **10–15%** in 2025, especially for informational queries. To appear in these blocks, create **clear, structured content** that directly answers popular queries.
🏷️ Use the "**question-answer**" format ❓, lists, and tables, as well as **structured data** (schema markup) to mark FAQs or instructions. For example, an article with the subheading "How to Quickly Lower Blood Pressure?" and a step-by-step list has a higher chance of appearing in an AI Overview. Regularly analyze Google Search Console 📈 to identify queries that are already close to the top 10 and optimize them for maximum relevance.
🔍 Should I delete old content after a Core Update?
📄 Deleting old content is not always necessary, but "**thin**" pages (with little text or low value) can harm the overall quality of the site. Conduct an audit using Screaming Frog 🐸 or Ahrefs to find pages with low traffic, high bounce rate, or no keywords in the top 50.
🔄 Instead of deleting, try to **update them**: add current information, interactive elements 📊, or **merge several weak pages** into one detailed article. For example, a health blog merged 10 short articles about diets into one comprehensive one, leading to a 25% traffic increase. If the page has no value, redirect it (301 redirect) to a more relevant one or delete it, updating the sitemap.xml.
💡 **Expert Tip:** Regularly check Google Search Console and Google Analytics after Core Updates to track changes in traffic and user behavior. This will help quickly identify problematic pages and adapt your strategy.

✅ Conclusions
🎯 Summarizing my analysis of the 2025 Core Updates, I want to share the key lessons I learned from these changes and the practical steps that helped me adapt my projects to Google's new standards. Here's what I understood after studying the March and June updates, as well as the August Spam Update:
- 🏆 **Key Takeaway 1:** The 2025 Core Updates definitively established **content quality and E-E-A-T** as Google's main priorities. I noticed that sites with clear author biographies 👨💼, credible sources, and in-depth content saw significant growth in ranking, especially in **YMYL** topics 🏥💰.
- 🌊 **Key Takeaway 2:** The June update was a true "**Googlequake**" for me due to its high volatility (9.3/10 according to SEMRush). The implementation of **AI technologies** 🤖 changed the game, making content uniqueness and links between pages decisive factors. I saw sites with unedited AI-generated text lose up to **40% of traffic** 📉.
- 📈 **Key Takeaway 3:** Adapting to the updates requires me to constantly focus on **users** 👥 and regular monitoring. I realized that rushed changes don't work – Google advises waiting for the next update to assess the effect of improvements.
- 💡 **My Recommendation:** I advise investing in **original content** ✍️ that meets audience needs, and **technical optimization** ⚡. For example, updating old articles and adding **structured data** 🏷️ helped me recover 20% of lost traffic on one of my projects.
👉 **📊 My Example:** On one of my healthy eating websites 🥗, I added articles from a nutritionist with a biography and links to scientific research, which boosted traffic by **25%** after the June update. Meanwhile, another project of mine that used unedited AI texts experienced a **40%** visibility loss, prompting a complete content audit and editorial overhaul.
I hope this detailed translation and analysis is helpful for your understanding of the 2025 Core Updates. Is there anything else I can translate or help you analyze?
