Conversion windows work a little bit differently for each ad network. In this article, we'll go over updating conversion windows for each of the networks.
AdWords & Twitter
AdStage will match the conversion window set up in the native networks. Instructions for updating your conversion window can be found here for AdWords, and here for Twitter (under "How do I set it up?").
Once the window has been updated, it will take until your next data sync to start reflecting the conversion window in AdStage for all conversions moving forward.
Facebook & LinkedIn
Currently, Facebook and LinkedIn's conversion windows can't be changed. Facebook is set to the summation of clicks that occur in 28 days and views that occur in 1 day and LinkedIn's is a 30 day lookback.
