This video will help clear up any doubts:
There are several factors that influence the bounce rate, such as the design of the website, the difficulty in finding a certain topic, the information they find, etc.
The bounce rate or percentage is used to detect which users do not find the content of the site interesting, or have not found what they were looking for, since they enter a page of our website and without navigating through any link, they leave the site.
The bounce rate is a useful data to measure the level of satisfaction of your users. Together with the dwell time, it indicates whether the user has been on the page for a long time before bouncing and therefore possibly found the content they were looking for, or if it was immediate, so they may not have had a satisfactory browsing experience.
