ServerSpy's Server Ranks are generated through looking at a server’s last 5 days of player traffic. Servers listed on this database are either listed within the Master List for that particular game or from registered members Server Monitor Listing.

GeoRank: This rank is determined through a combination of World Game Rank, Game Mod Rank and Geographical Location. This rank should always be your highest and most applicable.

World Game Rank: Servers are ranked by world dominance within a certain game, for example all HalfLife servers regardless of mod.

World Mod Rank: Servers are ranked through the game type and mod. Similar to GeoRank with the exception that its all about world dominance and not just in a particular country!
