How does site stats count visits ?

[Ainz]

Stats for June on one of my sites

That site is also monitored by Matomo
June

I do not understand the HUGE difference.

Care to elaborate on that?

[exekutive]

does Matomo filter out webcrawler bots?

[Ainz]

Yes, it should. It is a competent Google Analytics alternative.

Edit/
A more relevant question is if Astat does filter anything at all...?

Some well known bots can be filtered by the No Stats For Robots extension. You could add a regex to its $bots array list in plugins/no_stats_for_robots/main.inc.php if a specific bot hits you violently.
