Computer screen displaying Google Search Console dashboard with impression data graphs

On April 3, 2026, Google officially confirmed that a Search Console bug had been inflating reported impressions since May 13, 2025, according to a report by Search Engine Land. For nearly 11 months, the data that millions of websites relied on to guide their SEO decisions was simply wrong.

What happened

A logging error caused Google Search Console to systematically over-count impressions in the Performance report. Google updated its Data anomalies page to confirm the issue.

In plain terms: every time you checked your impressions in Search Console since May 2025, the number displayed was higher than reality. Clicks and other metrics were not affected.

Key takeaway: The fix is rolling out now. Over the next few weeks, expect your impressions to drop in the Performance report, this won't be a real visibility decline, just corrected data.

Why this matters for your SEO strategy

Impressions aren't a vanity metric. They're the denominator in your CTR (click-through rate) calculation, one of the most commonly used indicators for content strategy decisions. If impressions were inflated, your actual CTR was mechanically underestimated.

Real consequences for businesses that relied on this data:

  • Content wrongly labeled as « underperforming », an apparently low CTR may have been masking content that was actually converting well
  • Biased editorial decisions, page rewrites, keyword abandonment, and budget shifts based on incorrect numbers. A proper Free article could have caught these inconsistencies
  • Inaccurate client reports, SEO agencies that reported « impression gains » since May 2025 may need to revisit their reporting

What to do now

  1. Don't panic if impressions drop, it's the fix, not a penalty. Annotate your reports with the April 3, 2026 date to distinguish the bug correction from any real visibility changes.
  2. Recalculate your historical CTRs, since clicks were accurate, only the denominator (impressions) is changing. Your true CTRs are likely better than what you thought.
  3. Reassess your « underperforming » content, pages you sidelined may deserve a second look with corrected data.
  4. Diversify your data sources, never rely on a single tool. Cross-reference Search Console with your analytics, AI Overview data, and third-party tools (Ahrefs, Semrush) for a complete picture.

Our take

11 months of false data without anyone noticing. Not Google, not the SEO community. It's a stark reminder: Google's free tools are not infallible. And strategic decisions based on a single data point are dangerous. The SEO that works in 2026 is the one that cross-references signals, questions metrics, and takes nothing for granted, even when it comes from Google. A good starting point: master the fundamentals of technical SEO.
