At this time we are not providing the list of factors used in the Trust Factor matchmaking system. We don’t want players to have to worry about any particular action while they’re playing CS:GO or other games on Steam. Additionally, Trust Factor matchmaking will get continuous updates, and any list of factors would become outdated very quickly. In general, Trust Factor is determined by looking at a user's past experience in CS:GO and on Steam to ensure the system is as accurate as possible.
No. The goal with Trust Factor is to provide a better matchmaking experience without players having to worry about optimizing anything. Trust Factor matchmaking will try to match similar players, but like skill groups, the range of players on a server will vary depending on the time of day, the player's region, and the maps they’re queuing for.
The only way to improve a Trust Factor is to be a positive member of the CS:GO and Steam community. Trust Factor matchmaking will continue to be adjusted, but all players have to do to improve their matchmaking experience is continue playing CS:GO and other Steam games legitimately. The more a user plays, the more information the system has and the easier it will be for the system to determine who they should be matched with.
Yes. Phone numbers and CS:GO Rank are among the factors used in the new Trust Factor matchmaking system. Users who had Prime Status before will benefit from this and their in-game experience. If you have not linked your Steam account with a phone number for Prime we encourage you to do this; doing so will improve your matchmaking experience.
For more information, please see our Prime Account Matchmaking help article.
Not necessarily. Trust Factor is impacted by a user's experiences on Steam as well as CS:GO. If you have been a positive member of the Steam Community in the past, you’ll likely enter CS:GO with a high Trust Factor.
If you feel like your matches are poor because of Trust Factor, feel free to send an email to the address below with the subject “Trust Factor Feedback”:
Please include a description of your experience and your Steam ID so we can investigate; this will help us improve Trust Factor matchmaking going forward.
In these situations we recommend you have your friend (who you believe to have the lowest Trust Factor) email us at the address previously provided with their Steam ID and information. Be aware that when players are in a party, we use the lowest Trust Factor of any individual in the party for matchmaking purposes.
