A year ago, the IAB Tech Lab released ads.txt to help stop the sale of counterfeit inventory for ads.
The text file, posted on each domain or sub-domain owned by a publisher, indicates the only resellers, direct sellers or others who are authorized to represent that site’s inventory. The New York Times’s ads.txt file, for instance, will list the only resellers who can sell the space on its site, thus preventing fraudsters from selling space for which they don’t have the rights.
But there are a lot of publishers out there using ads.txt, and managing all those publishers’ text files can be a pain. One potential solution, for instance, is a blockchain-based application directly launched late last year by ad blockchain firm MetaX.
Now, the IAB Tech Lab is offering its own roundup mechanism, an aggregation service that crawls over 2 million domains and subdomains. The result is an Excel .csv file that can be downloaded by subscribers from the Tech Lab’s site, at an annual fee of $5,000 for IAB Tech Lab members and $10,000 for non-members.
