You can find your bounce rate in Google Analytics. A high number of bounce rate (like 70 - 90%) often means there is something wrong with your blog OR your blog is not optimized for your readers. Things that can be wrong in this case are for example a slow website that doesn't load enough and they exit your blog, or because they get an error like a large cookie banner that takes up most of the screen. Also annoying pop-ups and unpleasant reading experiences are reasons. If your bounce rate is 100% there is something very wrong and you should immediately get to work to fix it or find tech help.
