Google partially resolves Search Console’s year-long data glitch

Google has confirmed that a longstanding data logging issue within Google Search Console has now been fixed. The glitch, which impacted impression tracking from May 13, 2025 through April 27, 2026, lasted roughly 50 weeks. Importantly, while the problem has been resolved for future reporting, the historical data from that period remains corrupted and will not be corrected.

Here is Google’s official statement on the matter: “A logging error prevented Search Console from accurately reporting impressions from May 13, 2025 until April 27, 2026. This issue has been resolved. As a result, you may notice a decrease in impressions in the Search Console Performance report. Only impressions and related metrics – CTR and average position – were affected; clicks were not affected by the error, and this issue affected data logging only.”

To be clear, Google has not retroactively corrected the data from that nearly year-long window. The fix only applies to data logged going forward. John Mueller of Google confirmed this on Bluesky, stating plainly that the old data will remain as is.

Why this matters for SEO professionals and site owners. When you review your Search Console reports, keep in mind that for almost a full year, your impression counts, click-through rates, and average position metrics may be unreliable. You may see a sudden drop in impressions in the performance report, but this is not a reflection of actual search performance changes. It is a direct result of the logging error. Clicks, fortunately, were never affected, so that metric remains accurate throughout the period. Always cross-reference this timeframe with other analytics tools to get a clearer picture of your site’s true performance.
