A core feature of the product is that it ships with support for Search Engine Optimization (SEO) by default. You do not have to configure any settings after the installation and can also customize the format of URL's as per your requirements. The software enables users to add listings under three different levels: Free, Premium and Sponsored. Users will be able to pay for the last two levels directly by using any one of the four premier payment gateways (PayPal, 2checkout, E-gold, Authorize.net), which has been integrated with the system. It also provides block components with which you can add Hot Link, Random Link, RSS Feed, and AdSense. You can also integrate other Ad services like WidgetBucks and LakeQuincy.

The product displays Google Page Rank along with the links and automatically generates Google Sitemap files at regular intervals. As you continue to use your site, the database becomes bigger and your site gets a lot of traffic. This will naturally decrease the load time of pages. But IndexU has built-in support for Output Buffering and Page Caching which will eliminate these issues completely.
