In the visits log report of Matomo for my website, a considerable number of visits are not from real person visitors.
Matomo does a good job at filtering most of the crawler bots and page speed tools but not all. Example: the page speed tests in Pingdom do not show up in the log but the same page speed test in Gtmetrix does show up in the log reports.
The way I am able to distinguish the bots visits is by the amount of time spent on a page. So, all these page speed tests and other bots spend a total of 0 (zero) seconds on the page.
Is there a way to filter out (purge) from the logs the visits / visitors that spend zero seconds on the visited pages?
