Google Search Console users just got word on a fix for a nagging data glitch. But here’s the catch. It only applies from now on. Nearly a full year of skewed numbers stays broken.
The problem simmered undetected for 50 weeks. From May 13, 2025, to April 27, 2026, a logging error pumped up impression counts in the Performance report. Click-through rates and average positions followed suit, since they’re derived from those impressions. Clicks? Untouched. Google confirmed as much in its official notice, stating, “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.” (Google Search Central)
Barry Schwartz broke the initial fix news on May 4, 2026, noting the half-measure in Search Engine Land. He pointed to John Mueller’s Bluesky post for confirmation: old data remains uncorrected. (Bluesky) The same day, Schwartz updated at Search Engine Roundtable, echoing Google’s update.
This wasn’t a sudden revelation. Back on April 3, 2026, Google first flagged the bug publicly, warning of drops as corrections rolled out. (Search Engine Land) SEOs watched impressions plummet in the weeks that followed, some mistaking it for traffic loss amid the March 2026 core update. Panic spread on forums and X. One agency head posted, “50 weeks of dirty data stays dirty. If you made SEO decisions based on Search Console in the last year — and who didn’t — some of those calls were based on lies.”
Why did it take so long? Logging errors like this slip through because Search Console samples data at massive scale, not every query. Impressions represent views in search results, a vanity metric prone to glitches yet central to optimization strategies. Teams chase CTR improvements, tweak positions, all on faulty foundations. Clicks held steady, a small mercy, but derived insights? Poisoned.
John Mueller doubled down on Bluesky. No backfill planned. Forward-only fix. SEOs now scramble to annotate dashboards, pivot to clicks and sessions. Level Agency advised emphasizing “clicks, sessions, and conversions as our primary performance indicators during this transition,” while marking the tainted period. (Level Agency)
And the fallout ripples. Historical benchmarks? Skewed. Year-over-year comparisons? Useless for that span. Agencies like those at PPC Land called it an 11-month unnoticed blunder, questioning Google’s monitoring. X chatter from Barry Schwartz amplified the story, with posts racking up views as insiders shared screenshots of dropping charts. (X)
Google’s track record on Search Console bugs adds context. October 2025 brought crawl data glitches; December saw indexing report gaps. (Mediology Software) Each erodes trust in the free tool millions rely on for indexing, performance, and diagnostics. Yet alternatives cost. Ahrefs, SEMrush fill gaps but lack Google’s proprietary view.
So what now? Export data religiously. Cross-check with Analytics. Ignore impression trends from May 2025 to April 2026. Focus on clicks, which stayed true. Reassess strategies built on inflated optimism—maybe that content push wasn’t bombing after all.
Industry voices urge calm. “Do not panic when impressions start dropping,” one LinkedIn post advised. But trust frays. When your core analytics tool logs lies for a year, decisions warp. Budgets shift. Careers hinge on bad intel.
Google resolved it. Kind of. Data from April 28, 2026, onward should hold. Watch for anomalies. And bookmark those official notices. Next glitch might hide longer.
