Bounce Rate is a gauge for determining if a page is effective or not. Each page gets a bounce rate between 0% and 100%, 0% meaning every person that visits that page interacts with it. On the other hand 100% means that every visitor is leaving the page without interacting in some way. The lower this number the better. Bounce Rate can be used to determine how effective a landing page is or how well you convert visitors to staying on the site.
