If you’re seeing a lot of “0 Action” visits in your Visits Log, this indicates that the Matomo tracking code on your website or app is not tracking any “Pageviews” for these visits (But is tracking other actions such as impressions).

The reason for the “0 Actions” visits may be for example media impressions (Such as images or videos) or form impressions when visitors visit a specific page on your website where you don’t have “Pageview” tracking setup.

This can be fixed by either adding the Pageview tracking code (_paq.push(['trackPageView']);) in the standard Matomo JavaScript tracker, or if you’re using Matomo Tag Manager by setting up Pageview tracking.

Alternatively, you can disable Form Analytics on specific forms (For example Login pages) by adding the data-matomo-ignore tag to your form.
