One cool feature of this script is that it uses a built-in database and doesn’t require a MySQL database of its own. This helps make installation and maintenance much easier. The most important feature of LinkEX, and the one that really allows this free script to help manage your links is the backlink-checker capabilities that are built in. LinkEX can retrieve the web page which supposedly has a link back to your site, and make sure a link really is present. You can even set the back link checker on auto pilot using cronjob or something similar. That’s a great feature to find in a free program like this.
