We live in a web world in which space is vital and because of so much information and articles gathered in one site, you have to come with strong strategies to optimize the ergonomics of your website. Doing a good job with placing elements can increase the number of page views for your website, the website traffic, the user interest and with those, the website revenues.
Personally I am a big fan of professional web elements that can handle related content in a good manner and which can also provide users with all the information they need. Bellow you have some creative WordPress plugins to help you display related content in a very friendly and unique way.
This plugin is pretty minimalist and it is perfect if you want to keep your website on a low profile and you are just interested in text and no images. Just like the others, the plugin shows a nice box containing a link to the related article and some small description of that article.
This plugin works in partnership with the SimpleReach.com website. The thing is you will benefit of using their advanced technology for displaying related content, but you will have to keep the link to Simplereach.com there.
