Bounce rate is expressed as a percentage of the total number of visitors to the site. For example, if a website has a bounce rate of 50%, this means half of the visitors to the site viewed only one page before leaving.
Bounce rate is often used as a measure of the effectiveness of a website or a particular page on a website.
A high bounce rate may indicate that the content on the site is not engaging or relevant to the visitor, or that the site is not easy to navigate.
A low bounce rate, on the other hand, may indicate that visitors find the content on the site interesting and are sticking around to explore more pages.
Bounce rate is typically measured using web analytics tools, such as Google Analytics. It is important to note that many factors can affect bounce rate, including the quality of the content on the site, the design and layout of the site, and the user experience.
