WP Content Discovery Plugin is a free plugin for WordPress that is meant to accelerate traffic to your website.
It accumulates blog posts of similar content and displays them on your posts and pages, thus creating more content immediately. Your viewers will be able to see and click on these relevant blog posts links from your website. The same goes for your blog post which appears on other websites.
The concept is great, and WP Content Discovery claimed they have racked up millions of traffic with this method.
And here is the best part, it is FREE to use for one website and if you want to have the plugin on all your websites, you pay a one-time fee of USD 10. Yes, ONLY USD10!
This is my LOWDOWN after trying it
Issue 1: There are just too many missing images and repeated links across a 3×3 blog roll grid.
Issue 2: The problem (missing image) continues with the WP Content Discovery widget which you can place in your sidebar.
Issue 3: Dead links are very common and upon clicking some of the blog posts, I end up with this error instead.
With all these backend issues, WP Content Discovery is a risk to your website. I have written in to suggest a refund for the above reasons. I am not sure if that request would be answered. In any case, until it beefs up the backend and be thorough with their selection process of websites, I do not recommend anyone to use the plugin, FREE or otherwise.
