How does Inventory Change work?

lnventory Change estimates how many ads are being launched or paused, by day, over time.

The Green Bars illustrate the count of ads estimated to have been set live on a given day (left axis) while the yellow bars illustrate the estimated count of ads which were paused on a given day. 

The Red line (right axis) illustrates the count of ads believed to be active/live on a given day. 

The Inventory Changes data can help Apptopia users better understand the campaign scale and/or optimization strategy at a point in time for an advertiser. Match this data with the "first seen" and/or "last seen" data below Inventory Changes to get a a sense for what creatives advertisers are likely seeing success from vs. ads they are turning off.
