Bounce Rate is the percentage of single-page sessions (i.e. sessions in which the person left your site from the entrance page without interacting with the page).
The lower the bounce rate percentage, the better. This means more people are exploring your website. However, you do have to bare in mind that users might leave the site after viewing a single page if they’ve found the information they need on that one page, and had no need or interest in going to other pages.
A good bounce rate is around 40-45%.
