In July 2025, Google Search Console users started noticing a significant issue with their Core Web Vitals (CWV) reporting, especially on mobile devices. Around July 10, users observed a sudden dip in their CWV Reporting, with data showing a complete stop in Core Web Vitals reporting. This anomaly led to confusion among many webmasters and digital marketers, who initially thought it was a site-specific problem. However, as the issue spread, it became clear that this was a widespread problem affecting many websites.

Google later confirmed that this issue was tied to the Chrome User Experience Report (CrUX), and specifically, a temporary disruption in CrUX’s data pipeline. But how does this affect website owners, and what can be done to address the problem in the meantime? Let’s dive into the details.

Not a Google Search Console Issue

Many users first assumed that the problem originated within Google Search Console itself. However, John Mueller, Google’s Senior Webmaster Trends Analyst, confirmed that there were no changes on the Search Console side of things. The CWV Reporting issue, instead, seemed to stem from the CrUX data pipeline that powers Core Web Vitals metrics in Google Search Console.

John Mueller’s Response on Bluesky

A user on Bluesky posted their concerns about the drop in CWV Reporting for mobile starting on July 14. Mueller responded by explaining that fluctuations in reported data could happen due to sample changes, which he believed were part of the normal ebb and flow. However, as more users reported similar issues, the problem became evident as more than just a natural fluctuation.

Mueller’s updated response reflected a growing awareness that the issue was affecting a large number of websites, not just one site or a few samples. He acknowledged the possibility of a CrUX reporting outage causing this unexpected behavior.

Understanding CrUX CWV Field Data

Before diving deeper into the issue, let’s clarify what CrUX CWV Field Data means.

CrUX (Chrome User Experience Report) provides user-centric performance metrics from real-world Chrome browser visits. It’s part of Google’s Web Vitals program and is a critical dataset for assessing Core Web Vitals. These metrics are based on actual users who have opted into sharing data about their browsing experiences, including page load performance, interactivity, and visual stability.

The CrUX dataset helps Google understand how real people experience websites across the globe, and it plays a significant role in CWV Reporting within Google Search Console.

The CrUX Data Disruption

According to Barry Pollard, a Web Performance Developer Advocate at Google Chrome, the recent issue with CWV Reporting is linked to a temporary dip in CrUX data, particularly on mobile. This drop in CrUX data resulted in a disruption of Core Web Vitals reporting on Google Search Console, with a noticeable stop in data for several websites beginning on July 10.

Pollard mentioned that Google is actively investigating the problem and might release a fix in the coming weeks. However, there is no specific timeline for when this fix will be fully implemented.

A Widespread Reporting Outage

What started as a single user’s inquiry soon spread across the community, with more users confirming the same issue. Alan Bleiweiss, a well-known SEO expert, posted a screenshot of the Google Search Console report showing a similar drop in CWV Reporting for other websites. This confirmed that the problem was not isolated to just one website.

Google’s Response to the Reporting Outage

Barry Pollard’s post on Bluesky confirmed that Google was aware of the CrUX data pipeline issue. He shared that a potential fix was in the works to reverse the temporary dip in the CWV pass rates. Although Pollard is not directly involved with Search Console, he confirmed that this disruption is tied to CrUX data, which fuels Core Web Vitals metrics.

As of now, Google has not released any further updates on when this issue will be fully resolved, but the company is actively working on it.

Key Takeaways from the CWV Reporting Glitch

1. A Sudden Drop in CWV Reporting

The Core Web Vitals (CWV) reporting in Google Search Console dropped significantly around July 10, especially for mobile performance. This resulted in users seeing no data or a drastic reduction in reported URLs.

2. It’s a Widespread Issue, Not Site-Specific

The issue isn’t isolated to any specific site. Multiple users reported seeing the same issue with their Core Web Vitals reports in Google Search Console, confirming that it was a broader, widespread problem.

3. The Issue is Linked to CrUX Data

While Google confirmed that the problem wasn’t on Search Console’s side, it appears that CrUX data, which powers Core Web Vitals reporting, was the culprit. Barry Pollard from the Chrome team acknowledged the issue and mentioned that a fix might be rolling out soon.

4. Google is Working on a Fix

Google has confirmed the CWV Reporting outage, and a fix is in the works. However, users may need to wait for a few weeks until the issue is resolved.

5. No Need for Immediate Action

Although the drop in CWV Reporting might seem alarming, Google has confirmed that this is a temporary issue, and no immediate action is needed. Websites can continue monitoring their Core Web Vitals, and normal reporting should resume once the issue is addressed.

What Can Website Owners Do in the Meantime?

If you’re experiencing a drop in your CWV Reporting in Google Search Console, don’t panic. This issue is temporary, and Google is actively investigating it. There’s no need to make immediate changes to your site based on this data. However, there are a few things you can do:

• Monitor Your Site’s Core Web Vitals: While reporting might be inaccurate, you can still manually track your Core Web Vitals using tools like Lighthouse and PageSpeed Insights.
• Stay Informed: Keep an eye on updates from Google regarding the fix for the CrUX reporting outage. Google is likely to provide more details soon.
• Optimize Site Performance: Even though CWV Reporting might be down, it’s always a good idea to continue optimizing your site’s performance. Focus on improving page load speed, interactivity, and visual stability to ensure your website is ready for when the reporting returns.

Conclusion: Understanding the CWV Reporting Glitch

The CWV Reporting glitch in Google Search Console is confirmed to be a temporary issue caused by a disruption in CrUX data. Although this issue has affected many websites, Google is actively working on a fix. Website owners should remain patient and monitor updates from Google, but there is no need to make drastic changes in response to this reporting glitch. Keep focusing on Core Web Vitals optimization, as it remains a crucial aspect of SEO and website performance, and the reporting will eventually resume once the issue is resolved.
