The bounce rate is a parameter of Google Analytics to measure the interest of a website based on the visitor's circulation through it, at a higher bounce rate, less content visited, which means that another page similar to yours with less rate Bounce will be classified as better quality.

Rb = Tv/Te

Where Rb is bounce rate
Tv is a total one-page visit
Te is total entrance visits

The formula for calculating the bounce rate is quite clear and can be summed up in a simple equation: the number of users who leave the page after just seeing the landing page (the first page they see on the website) and who do not interact on it divided by the total users of the site. Therefore, if 40 users leave without taking any action on a page and we have 100 users in total, the bounce rate is 40%.
