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 of time.
Example: 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.
