What is Ads.txt?
Ads.txt (Authorized Digital Sellers) is an initiative from IAB Technology Laboratory. It is a simple, flexible and secure method that publishers can use to publicly declare their partners such as Doceree they authorize to sell their digital inventory to in a bid to improve transparency for programmatic buyers.
Ads.txt supports transparent programmatic digital media transactions. As a text file, ads.txt is easy to update, making it flexible to create and edit (example). Also, it can only be posted to a domain by a publisher’s webmaster that makes it valid and authentic.
What Problem Does Ads.Txt Solve?
When a brand advertiser buys media programmatically, they rely on the fact that the URLs they purchase were legitimately sold by those publishers or their partners.
The ads.txt prevents various types of counterfeit inventory across the ecosystem by improving transparency in the digital programmatic supply chain.
How Does Ads.Txt Work?
Ads.txt works by creating a publicly accessible record of authorized digital sellers for publisher inventory that programmatic buyers can index and reference, if they wish to purchase inventory from authorized sellers such as Doceree.
Publishers post their list of authorized sellers such as Doceree on their domain. Programmatic buyers can then crawl the web for publisher ads.txt files to verify.
How to implement Ads.txt?
There is a two-step process of getting ads.txt live for your platform:
Step 1: Create a txt page on your website root domain example: domain.com/ads.txt
Step 2: Insert the ads.txt line i.e. <FIELD #1>, <FIELD #2>, <FIELD #3>, <FIELD #4>
Field #1 Domain name of the advertising system
Field #2 Publisher’s Platform ID
Field #3 Type of Relationship
Field #4 Certification Authority ID (TAG*)
Example doceree.com, e86a40f0-6a78-47c8-a3a3-bf576afe006e, DIRECT, 2fdffb154ba9b221
NOTE: Since we only work with publishers directly, the only change in the ads.txt example above would be the Publisher’s Platform ID highlighted in red. It is unique for each platform and needs to be requested from your account manager at Doceree or firstname.lastname@example.org.
