I use this extension on a site where internal linking is important for SEO. First step is I select an internal article and decide on which keywords on the page should be automatically linked to other pages on the site. Then automatically any page that has the same keywords will will be text linked to that page. All of this is customizable by Section and Category.
Even more terrific is the incredible support. Submit a ticket and the response is quick. And they listen to users suggestions. I made a suggestion and two days later it was incorporated into their latest update. It was not a simple suggestion and I am sure it required some serious programming.
I rated this component Excellent. I would rate it even higher if it was possible. Excellemente!
