I want my website to have personalized recommendations, using typical state-of-the-art techniques like Collaborative Filtering - not just based on content like some blog plugins that already give you that.
There are many companies that provide plugins like this for e-commerce, but I cannot find the same for "regular" web page recommendation. What I'm looking for would in theory work just as these ones, but there's no product value, checkout, etc.
Basically, what I'm looking for is to have different recommendation types (based on similar users, based on users that read that recipe, etc.) to be placed at different parts of the pages.
Any service/software out there?
