Attention Webmasters: A Major Reporting Issue!
If you rely on Google Search Console for tracking your site's performance, brace yourself! Reports indicate a significant glitch affecting Core Web Vitals (CWV) for mobile users, first noticed around July 10.
What Happened?
Users began noticing a mysterious dip in reporting, with reports for overall mobile performance plummeting to zero by July 14. This abrupt decline has left many sites, not just one, in a state of confusion regarding their CWV metrics.
Not Just Your Site!
A curious user took to Bluesky to confirm their concerns, asking Google’s John Mueller if there was a known issue with the CWV reporting. The alarming drop, they noted, wasn’t limited to their site alone. Mueller initially suggested that changes in sampling sizes could cause fluctuations, indicating it was a normal occurrence—but soon it became evident that the problem was widespread.
The Response from Google: No Immediate Fix?
Despite the growing concern, Mueller confirmed on social media that the issue did not originate from Search Console functionalities. However, he hinted at possible complications stemming from the Chrome User Experience Report (CrUX), the data source for these metrics.
Understanding CrUX Data
CrUX collects real-world data from users opting to share their browsing experiences. This dataset provides insights into how everyday users interact with websites, forming the backbone of CWV metrics.
Acknowledgment of the Outage
As more users joined the conversation, confirming similar reporting issues, the situation led to a clearer picture. Barry Pollard, a Web Performance Developer Advocate for Chrome, publicly acknowledged the CWV metric dip and confirmed that a fix was under investigation.
