In my oppinion, the bounce rate of your site plays a huge role when it comes down to the ranking part. The bounce rate is the rate of visitors that visits your site and bounces back to google, by pushing the return button. The bounce rate can decrease if people start to go through your page and clicking on different links.
In order to get people to click through your website, you need to have engage content. Content that is usefull in their eyes, that shares a lot of value. I highly belief if you are able to write great content, you will be able to decrease your rate dramaticly, which is going to result in better rankings.
A lot of people are trying to use the fast way, publishing useless crap and get a bounce rate of around 80-90% (which is not great). This doesnt definitely help in getter your website ranked.
Watch the video below for more informations about bounce rate.
Short: Publish usefull content that makes people to engage with your website and you are good to go.
