Any Expert Here: In google Analytic Need one help.

On my google analytics, I see 70-80% 0:00 seconds visit duration stats even when my site is loading very fast and has tremendous speed results on all speed testing platforms, and my content is also very enagging. Can anyone please let me know why am I able to see so many 0:00 seconds sessions on my google analytics?

Possibly bot traffic or there’s some issue in your site use tools like gt metrix, think with google and figure the issue if you find nothing set up filters and this will stop showing this in analytics
