The term bounce rate is often used in connection with search engine optimization (SEO). The bounce rate shows the percentage of visitors to a website who only look at one page and then leave the site without any further action. If 43 out of 100 users only look at the homepage and then leave the site, you have a bounce rate of 43%. It is important to keep the bounce rate in mind for SEO, however, this value should be considered in connection with other key figures. A high bounce rate is not always a negative factor.
