Why authorization sellers with ads.txt in Adsense?
Authorized Digital Sellers, or ads.txt, is an IAB initiative to improve transparency in programmatic advertising. Publishers can create their own ads.txt files to identify who is authorized to sell their inventory. The files are publicly available and crawlable by buyers, third-party vendors, and exchanges.
Use of ads.txt is not mandatory, but is highly recommended. The ads.txt file can help you protect your brand from counterfeit inventory that is intentionally mislabelled as originating from a specific domain, app, or video. Declaring authorized sellers can help you receive more advertiser spend that might have otherwise gone toward counterfeit inventory. [Powered by Adsense Support]
