Bounce rate is a term used to track web traffic. A ‘bounce’ is a visitor who comes to one page of a web site, but leaves before clicking on any other pages or taking any type of action. The Bounce Rate is the number of single-page visits divided by all visits to a site, which results in a percentage of bounces to non-bounces. Bounce rates matter most for multi-page web sites where key information is not located on one page. In the case of a blog or micro-site which may only be one page, the bounce rate isn’t a good indicator of success. Bounce rates can be an indicator of lack of conversions and can also affect Google rankings.
