Google has confirmed a “logging error” that affected the product snippets reporting within the Google Search Console performance report. The issue occurred between May 15, 2024 until May 27, 2024 and resulted in an increase in clicks and impressions for the Product snippet search appearance type within the search performance report and impressions overlay in the product snippet rich result report.
This is just a reporting issue and has no impact and real Google Search rankings.
More details. A week ago, we noticed a weird spike in impressions and clicks for product snippets. Some thought it might be related to AI Overviews, but John Mueller from Google said it is unlikely related to that. He wrote:
The folks here are looking into the details of this, and it does look like a bug on our side in Search Console reporting (and FWIW it doesn’t seem to be related to AI Overviews at all, but I can see how that would be tempting). Once we know more (and ideally have fixed it), we’ll likely add an annotation in Search Console & an entry in the data anomalies page.
Google details. Google then posted an update here, confirming the reporting issue. Google wrote:

What it looks like. Here is a screenshot showing the spike for this report:
Why we care. If you noticed this unusual spike, you were not alone. Just note that this was a reporting glitch in Google Search Console so that you know what happened.
It would be best to ignore that data, within that date range, for client and internal reporting purposes.
