Numerous publishers have reported an issue with AdSense reports showing "0 clicks" since March 2023, which could potentially be an error. Google has not yet confirmed the issue but there are numerous complaints from publishers.
Google AdSense publishers have been complaining that the report that shows their clicks showings 0 on the AdSense report page is wrong since March 2023.
Numerous publishers have been reporting a "0 click" issue in the Google AdSense Forum.
This issue is distinct from policy violations or ad display problems, as CPM ads revenue is still being counted. However, AdSense ads clicks are either being removed from publisher accounts or not being counted at all. As a result, publishers are unable to earn anything unless CPM revenue is generated. Despite extensive discussions on the AdSense Community and other platforms, the cause of this issue remains unknown.
