Bounce rate is a metric that measures how many people navigate away from a site after only viewing one page. The lower the bounce rate is, the better a website is at engaging and retaining visitors. While a bounce rate of about 40% is to be expected, anything higher indicates the website is failing to engage users or is taking so long to load that users lose patience and click away.
While bounce rate isn’t a recognised SEO ranking factor, and it’s hotly debated whether it directly impacts search engine rankings, it can still provide insight into SEO performance. A high bounce rate can say a lot about a site’s overall performance and ability to engage users.
