Website bounce rate is defined as the percentage of single interaction visits on a webpage, meaning the visitor came to one page on the website and then left. A secondary pageview means that a visitor has further engaged with your website. Not every visitor is going to view a secondary page on your site, as they may have only come for a single piece of information (such as an event time and location), so a bounce rate of about 26-40% is considered a good range. However, the average bounce rate for most websites is around 41-55%. If your website is even higher than this, you may want to consider putting a strategy in place to better engage your visitors online.
Reducing bounce rate is important if you are looking to increase engagement with your website visitors. Higher levels of engagement can help contribute to increased conversions, which is when a visitor takes some sort of action on your site (such as leaving contact information or purchasing a product). If you are looking to turn more of your website visitors into potential sales prospects, you may want to look into making some site updates to make sure visitors are not leaving the site immediately.
