Bounce rate is a term used in web traffic analysis to represent the percentage of visitors who enter a website and then leave without continuing to view other pages within the same site. It is calculated by counting the number of single-page visits and dividing that by the total visits, then represented as a percentage of total visits. Bounce rate is a measure of "stickiness," and an effective website will engage visitors deeper into the website, encouraging them to continue with their visit. A high bounce rate indicates that the website is not doing a good job of attracting the continued interest of visitors, and visitors only view single pages without looking at others or taking some form of action within the site before a specified time period. Bounce rate can be used to help determine the effectiveness or performance of an entry page at generating the interest of visitors, and an entry page with a low bounce rate means that the page effectively causes visitors to view more pages and continue deeper into the website. However, a high bounce rate is not always a bad thing, and it depends on the websites goals and what kind of site it is. For example, if a websites success depends on users viewing more than one page, then a high bounce rate is bad, but if a website is a single-page site like a blog, or offers other types of content for which single-page sessions are expected, then a high bounce rate is perfectly normal. A good bounce rate is dependent on the type of website, and under 20% is generally good in ecommerce, but under 65% is good on blogs, for example.
