Pictures do speak a thousand words and they express your thoughts in a better way. And related posts will of course show more options to your readers and thus they stay longer on your blog.
So a perfect mixture of these two will definitely help you to build a more successful blog.
Moreover this widget overcomes another problem in the previous related posts widget, which used to show only the latest related posts. But this widget crawls all your blog and then randomly selects the related articles.
There are no ads in the widget and you do not even have to register in their website to use the widget.
Simply visit LinkWithin, enter the details, click on “Get Widget“. In the new page, click on Install Widget button, and the widget will be ready for your blog.
Although there are some limitations in the widget, like you cannot customize it, but as they say and I have experienced too, the widget does get blend in to your blog easily.
Presently I am using this widget along with the previous widget, and I already have noticed many clicks through the widget.
I would recommend you to try this widget for at least a week.
