Bounce rate (sometimes confused with exit rate) is an Internet marketing term used in web traffic analysis. It represents the percentage of visitors who enter the site and then leave ("bounce") rather than continuing on to view other pages within the same site.
Bounce rate is a measure of the effectiveness of a website in encouraging visitors to continue with their visit. It is expressed as a percentage and represents the proportion of visits that end on the first page of the website that the visitor sees.
Bounce rates can be used to help determine the effectiveness or performance of an entry page at generating the interest of visitors. An entry page with a low bounce rate means that the page effectively causes visitors to view more pages and continue on deeper into the web site.
High bounce rates typically indicate that the website isn’t doing a good job of attracting the continued interest of visitors.
Interpretation of the bounce rate measure should be relevant to a website's business objectives and definitions of conversion, as having a high bounce rate is not always a sign of poor performance. On sites where an objective can be met without viewing more than one page, for example on websites sharing specific knowledge on some subject (dictionary entry, specific recipe), the bounce rate would not be as meaningful for determining conversion success. In contrast, the bounce rate of an e-commerce site could be interpreted in correlation with the purchase conversion rate, providing the bounces are considered representative of visits where no purchase was made. Typically, an average Bounce Rate for e-commerce is around 60%, with top performers operating at a 36% average Bounce Rate.
A bounce occurs when a web site visitor only views a single page on a website, that is, the visitor leaves a site without visiting any other pages before a specified session-timeout occurs. There is no industry standard minimum or maximum time by which a visitor must leave in order for a bounce to occur. Rather, this is determined by the session timeout of the analytics tracking software.
