Third-Party Ad Serving
September 9, 2021
Ads are typically either first-party served or third-party served. First-party served ads are ads being served by the media owner/publisher/network displaying the ads. Third-party ad serving refers to ads being served by the advertiser (or agency). Third-party ad serving allows advertisers to have a tighter control on the creatives and gives them slightly more visibility into the performance of the ads.
