Browsing History Recommender

This module adds two blocks:

1. Recommended for you
2. Users who browsed this node also browsed

Recommended for you

This block is a personal recommendation, based on what each user has read so far. The content is unique to every user. Will be the same on every page, but different users might see different things.

The "Recommended for you" block provide personalized node recommendations based on a user's node browsing history. The basic idea is that, for example, user A browsed node X, Y, where users who browsed X, Y also browsed W, V; then "Recommended for you" would display W, V for A.

Users who browsed this node also browsed

This block is node-based. The content changes on different pages, but it remains the same for all users on the same page.

To make the recommendations, the module uses the {history} table that keeps track of 30 days of users' node browsing history. Also, when you enable the "boost comments" option, the module then takes users' commenting history as browsing history as well.
