Ad account query data is pulled directly from the Facebook, Twitter, or LinkedIn APIs. The data is accurate at the ad account level, regardless of the Facebook page, Twitter handle, or LinkedIn page ads that the query runs against. That means that if the Facebook ad account for which you are graphing data ran ads for a Facebook page that is not being tracked in TrackMaven, an ad account query in reports would capture all data for that Ad Account, inclusive of data for ads run on any/all pages.
Data in reports for Facebook Ad Accounts is pulled in real-time for Facebook, Instagram, Audience Network, and Messenger ads. Data in reports for Twitter Ad Accounts is updated hourly.
