Loomia is a recommendation engine that is used by ecommerce and content websites to suggest new stuff to users. They easily allow sites to add suggestions like, “based on your browsing history we recommend ” and “people who liked this also liked .” They claim their recommendations drive up page views and increase click-throughs by up to 20%.
The recommendation widgets are easily integrated into your site and customizable. They say you can “get up and running in minutes” and that their “hosted service requires no software installation and works for large and small sites.”
They charge a CPM for content sites and a percentage of sales that can be tracked to referrals for ecommerce sites. They also offer a free version, but it includes text ads.
