Club Recommendation Algorithm

How are clubs ordered?

The order that clubs appear on the home page for the default ordering method is determined by several criteria. A recommendation algorithm uses these criteria to ensure that students receive the best experience when browsing for new clubs and that clubs can effectively reach their target demographic.

How does the club recommendation algorithm work?

The recommendation algorithm uses the following non-targeted criteria to determine how to order clubs on the home page. Clubs are ordered by points, and then this ordering as adjusted based on personalized data. The points obtained from these categories is calculated and saved once per day at 4 AM, so make your changes early! The criteria are:

Matches Target Schools

Specifying all of the schools is the same as specifying none of them.

Matches Target Majors

Adding target majors will cause the club to appear higher on the home page for students in those majors. Clubs that have specified fewer majors are more likely to appear higher than clubs that have specified more majors, for relevant students. Specifying 10 or more majors is the same as specifying no majors.
