The bounce ratemeasures the number of people who arrive at your site, then leave your site after viewing just one page (instead of going on to explore other pages on the site). Such a visit is called a bounce.
A bounce usually means that the visitor arrived on your site, took one look at the page they landed on, decided it wasn’t right for them, and left. Therefore, your site’s bounce rate can give you a good idea of whether your visitors are engaging with your site.
To calculate a website’s bounce rate for a given period, you divide the number of bounces by the total number of site visits during the period, and multiply by 100. For example, say your site gets 1,000 visits in a 24-hour period, of which 300 are bounces. Your site’s bounce rate is therefore (300 ÷ 1,000 × 100 ) = 30%.
You can also calculate bounce rate on a per-page basis. For example, if 1,000 visitors enter your site on a particular page and 300 of those visitors leave without viewing any other pages, then that page’s bounce rate is 30%.
