Do you want to increase visitors time on your site, and want them to read your older articles on your blog? However, you forgot what the link is for your older content on your blog, or you do not have the time to link to your older posts from your newer posts. Also, by having related links on your page, it will make it easier for search engines to index more of your older articles which were not indexed.
There is a plug-in for WordPress which allows your blog to automatically find related posts for a current article which a reader is reading. I have been using this plug-in for a few months and it works pretty well.
By having more related post links on your blog, your readers can find posts which they might like on your blog easier, so they are more likely to stay and read a second article, so your bounce rate decreases while your readers time on site will increase.
In the Related posts settings, you can change the title of the plug-in, choose a title tag, and set the maximum amount of related posts in WordPress, exclude categories, display comment count, display publish date, auto-insert related posts, display related posts in feed, display post excerpt, no related posts settings, related posts with thumbnail.
The Plug-in also looks very clean in the Sidebar and footer of your articles.
