Bounce Rate is defined as the percentage of visitors that leave a webpage without taking an action, such as clicking on a link, filling out a form, or making a purchase.

Bounce Rate is important for three main reasons:
- Someone that bounces from your site (obviously) didn’t convert. So when you stop a visitor from bouncing, you can also increase your conversion rate.
- Bounce Rate may be used as a Google Ranking factor. In fact, one industry study found that Bounce Rate was closely correlated to first page Google rankings.
- A high Bounce Rate lets you know that your site (or specific pages on your site) has issues with content, user experience, page layout or copywriting.
