Bounce rate, basically, means the percentage of single page visits or the visits in which the visitor leaves your website from the landing page. The percentage exposes the number of visitor who arrived at your website but bounced out of your site. There are various reasons why the visitor bounces out of your site like may be he didn’t like the page, the page took long to load, maybe he found the page not really informative or he got exactly what he was looking for.
Well, whatever the reasons might be, one would always want their visitors to scroll over their site and reduce bounce rate of their site, especially on a blog where you would have excerpts on the home page. A high bounce rate means less visitors and low conversions.
