When users come to a website and immediately hit back, close the browser or leave without interacting with the site, it is considered a bounce. Depending on traffic source, the bounce rate of your landing pages and websites can be well into the double-digit percentages. To calculate the bounce rate, take the number of people that “bounced” and divide by the overall number of users for a specific period.
For instance, if we had 1,000 visitors on a website today, and 350 of them “bounced,” we take 350 / 1,000 which equals .35. To get the whole number percentage bounce rate, we multiple .35 ** 100 for 35% bounce rate.
