On March 27, 2026, Google launched the first broad Core Update of the year. The official wording is "a regular update to improve the relevance of results." But behind the scenes, thousands of sites saw a drop in clicks and impressions in Google Search Console.
At the same time, Google explicitly states: there are no penalties. So why is traffic disappearing?
This article is not a retelling of official statements, but an analysis of what is happening: with data, with personal experience in GSC, and with concrete conclusions that most publications on this topic avoid.
What Google Says - Briefly and to the Point
According to Search Engine Land, Google characterized the update as follows:
- It's a broad core update — a comprehensive reassessment of the algorithm, not a targeted intervention.
- No penalty. No messages in GSC under "Manual Actions."
- Rollout duration — up to two weeks.
- The goal is to better promote relevant and useful content.
- Recommendation: do not make drastic changes during the rollout.
It sounds neutral. But in reality, there's a rather specific logic behind it — and several pitfalls that official statements remain silent about.
What's Happening in Practice
Numbers You Can't Ignore
According to ClickRank:
- The SEMrush Sensor volatility index reached 9.5 out of 10 — one of the highest indicators in the entire history of observations.
- Over 55% of tracked sites recorded position changes within the first two weeks.
- Some sites lost 20% to 35% of their organic traffic in the first week alone.
Patterns Observed by Webmasters
- Positions "jump" daily, even hourly.
- The same page can soar and fall within a day.
- Some sites — especially those with niche expertise — are growing rapidly.
- GSC metrics do not stabilize until the rollout is complete.
Personal Experience: What I Saw in GSC on webscraft.org
This website about web development — webscraft.org/blog — was also affected by the update.
After March 28, the picture in Google Search Console became unstable: clicks and impressions began to fluctuate sharply day by day. Not a smooth decline — but chaotic jumps. One day — normal numbers, the next — minus 10–20% impressions. Then partial recovery. Then down again.
This doesn't look like a technical problem or de-indexing. This is a typical picture of a live rollout.
Why this happens technically: during a rollout, Google gradually updates its data centers worldwide. The same query can hit an "old" or "new" index — depending on which data center is processing it at that moment. This is why GSC shows chaos: it's not one algorithm, but effectively two, processing traffic simultaneously during the transition period.
This is precisely why Google recommends not to draw conclusions or make changes until the rollout is complete. What currently looks like a "drop" might just be noise from the transition between index versions.
The Double Whammy of March: Why This GSC Data Is So Hard to Read
A point that almost no one writes about in detail — and it's critically important for correct diagnosis.
In March, two separate updates occurred back-to-back:
- Spam Update — March 24–25. Completed in less than 20 hours. A targeted strike against manipulation: cloaking, artificial links, mass AI content without oversight.
- Core Update — March 27. A broad reassessment of content quality across the entire index.
The problem is that if your traffic started dropping between March 24 and March 30 — you physically cannot understand what exactly affected you. The data in GSC is mixed from two different mechanisms with completely different logic.
Spam Update is about rule violations. Core Update is about relative content quality. These are fundamentally different reasons, and the response to them is different. But your GSC graph won't show this.
How to distinguish in practice:
- The drop started sharply on March 24–25 and stopped — most likely, the spam update.
- Chaos and fluctuations continue after March 27 — this is the core update in the process of rolling out.
- Dropped sharply on the 24th and then continued to fluctuate — got both simultaneously.
According to Search Engine Land observations, this sequence was intentional: Google first "cleaned" the index of manipulations, and then reassessed what remained. The spam update created a cleaner baseline — and the core update then worked relative to it.
The Main Reason for Drops: You Haven't Gotten Worse
The key insight many miss.
A Core Update isn't a penalty for doing something wrong. It's a change in the relative quality assessment.
Simply put: your site might have stayed the same. But other sites in your niche have started to answer queries *better*—from the perspective of the updated algorithm. And Google has simply redistributed positions.
This is competition, not punishment.
According to an analysis by Magnified: a drop in rankings after a core update means Google has changed its quality assessment of your content relative to competitors—not that you've broken the rules.
Why "No Penalty" is Misleading
Technically, Google is right: a penalty is a separate mechanism. It comes with a notification in GSC under "Manual Actions." A Core Update doesn't work like that.
But in practice, the difference between a "penalty" and a "re-sorting of search results" is almost imperceptible to a website owner. Traffic drops in both cases.
Therefore, the wording "we are not penalizing anyone" is technically correct, but it doesn't answer the question "what to do next."
AI Overviews: A New Type of Traffic Loss Not Visible in GSC
There's another reason for a drop in clicks that most articles are silent about—and it's not directly related to Core Updates, but it significantly amplifies their effect.
Google is actively expanding AI Overviews—blocks with automatic answers directly in search results. And here's what's critically important to understand: your page might stay in the same position but receive half the clicks. For details on how AI Overviews are changing search and which strategies work—read our separate article: How AI Overviews are Changing Search: Survival Strategies for Websites.
According to an analysis by Launchcodex based on a study by Seer Interactive (3119 informational queries, 42 organizations): CTR for pages where Google showed an AI Overview dropped by 61%—from 1.76% to 0.61% during the observation period. And this trend is only intensifying.
- Query "how to make a responsive menu in CSS"—Google answers directly in search results. No click.
- Query "why doesn't flexbox work"—AI Overview gives a short answer. No click.
- Your position in GSC—the same. Impressions might be the same. But clicks—significantly fewer.
This is not a bug or a consequence of an update. It's a new search results structure. And the only strategy that works against it is content that cannot be compressed into a single paragraph: real-life cases, personal developer experience, original code examples with explanations why it's done that way, conclusions from practice that are not in the documentation.
Which Sites Are Losing Positions Now
Based on data from Abhishek Gautam and Digital Applied:
- Articles that simply rephrase the top-10 results without any original conclusions.
- Content generated en masse without editorial oversight—AI farms lost 60–80% of their traffic.
- Materials without first-hand experience or original data.
- Sites with broad topics and superficial coverage of each subject.
- Pages where the search intent does not match the user's actual query.
Which Sites Are Growing
- Original Data—own research, screenshots from real tools, own analytics. According to Digital Applied, such sites showed an increase in visibility by 15–25%.
- Niche Expertise—sites that deeply cover one topic, not a little bit of everything.
- Real Author—the presence of a verified author with experience in the subject positively impacts the E-E-A-T assessment.
- Clear Intent Match—the page provides exactly what the person was looking to find.
According to observations by Abhishek Gautam, sites with their own research and verified expert authors are growing steadily—and simultaneously are more often appearing in AI Overview answers. This means the same strategy solves both problems: search rankings and visibility in AI answers.
What to do right now
Checklist for those seeing fluctuations in GSC:
- ✅ Don't panic or make drastic changes during the rollout — it might still be ongoing.
- ✅ Establish a baseline — save your GSC data from before March 27th for a clean comparison.
- ✅ Separate Search and Discover traffic in GSC — they are separate tabs and react differently.
- ✅ Determine what affected you — a spam update (March 24-25) or a core update (March 27+). They have different reactions and require different strategies.
- ✅ Analyze pages, not the entire site — drops are usually uneven across content clusters.
- ✅ Check the intent — does your article truly answer what a person is searching for?
- ✅ Evaluate "informational value" — if your unique contribution is removed, what remains?
- ✅ Monitor impressions — they drop before clicks and are an early signal of changes.
When to draw conclusions — and an honest take on recovery
According to Search Engine Land, the rollout can last up to two weeks. It's advisable to analyze data no earlier than a week after its completion.
But there's an important point that most articles mention in fine print at the end — not at the beginning where it belongs.
Recovery after a Core Update most often happens not after your actions — but after the next Core Update.
Google officially confirms this: even if you significantly improve your content, the algorithm will register it and mostly re-evaluate positions during the next broad update. And the next Core Update is approximately another 3–4 months away.
What this means in practice:
- Don't expect a quick recovery after your own changes. This is demotivating and hinders strategic thinking.
- Start improving your content now — so that the next update "sees" the changes.
- Track the trend, not daily numbers — they will remain chaotic for a long time.
The rule is simple: gather → wait for stabilization → analyze → act → wait for the next update. In this exact order.
Conclusion
A Core Update is not a punishment. It's a re-evaluation of competition for quality.
In March 2026, this was complicated by three factors simultaneously: a double hit of spam + core updates, making GSC data unreadable; AI Overviews stealing clicks even with maintained positions; and record volatility during the rollout, where panic is the worst reaction.
If your content is just "another article on the topic" — it risks losing to those who add something truly new. If you write from your own experience, add real data, and address a specific query better than others — you are already moving in the right direction.
The algorithm is simply becoming more sensitive to the difference between these two approaches. And this difference will only grow.
