Several of you have asked how the order of groups is determined when someone searches (or browses) for a group within the Groups Search Directory, so I thought I’d take the opportunity to explain.
The order is based on a combination of factors that includes the number of members, the frequency of activity, and whether or not the group moderates messages or members. To prevent gaming of the system we can’t divulge the exact algorithm (just as search engines can’t tell you exactly how they rank results), but all of these elements play a role and may explain the fluctuations that some of you have reported.
Our ultimate goal is to serve up the highest quality Groups based on the topic or keyword being searched. If you feel that our algorithm isn’t performing well, we’d love for you to share examples of searches or categories that aren’t providing the best results first, so that we can work to improve the algorithm over time.

P.S. Just to be clear, we see moderation as a positive not a negative.
P.S.S We don’t rank groups overall, just related to particular searches or categories. To see how your group ranks, go to http://www.groups.yahoo.com and type a search term related to your group.
