AdSanity Impressions Addon GPL Overview:

With AdSanity Core, you are limited to expiring ads based on dates. With the Impressions add-on, you now have the ability to expire an ad after a specific number of views. This opens up the ability to charge your advertisers based on the visibility of their ads. While AdSanity Core doesn’t offer the ability to charge advertisers for ad space directly, we’ve written about how to set this up using a combination of other plugins including how to set up self-service reporting with our Advertiser Reporting add-on.

Requirements: All Add-Ons require the latest version of AdSanity Core.
