Website bounce rates are determined by how many visitors leave a page without completing some action, such as purchasing something, filling out a form, or clicking on a link.
Bounce rates are important because they can indicate that the content on a page is irrelevant or confusing to your site visitors.
If your home page has a high bounce rate, for example, that indicates people are merely viewing it, then clicking away.
To better understand the bounce rates, it's important to examine other page metrics.
Check your website's visitor time, their location, the device they're using, and whether your content and experience are aligned with those factors.
Analysis of these factors may reveal patterns that will help you fix bounce rate issues.
The bounce rate does not directly affect organic ranking.
Indirectly, it affects other ranking factors that Google values - slow page speeds, low-quality designs, and poor mobile optimization, for instance.
Increasing your bounce rate won't improve your Google ranking. But lowering your bounce rate is usually a good indicator that your content is engaging, valuable, or useful.
