content recommendation

If you've ever seen a list such as “Popular News Stores,” “Customers who bought this item also bought” or “Other stories by this author,” then you're familiar with the idea of related and recommended content, and the value these recommendations can add for website visitors. They also add value for site owners, since suggestions (and especially good suggestions) of additional content make people more likely to stay on your site for longer, view more pages, and buy more products.
