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 SEO audit 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.
