A metric that shows how many visitors came to your website and then left immediately after without performing any actions or browsing any of your other pages. A rule of thumb is the lower bounce rate the better. Having a high bounce rate (over 70%) is a cause for concern and can be caused by many different issues like slow page load, low-quality content, unresponsive landing page, using too many ads, your visitors not finding your page relevant for the keywords they used etc.
