Understanding Authorized Digital Sellers through Ads.txt
Ads.txt, which stands for Authorized Digital Sellers, is a critical framework introduced by the IAB Tech Lab in 2017 to enhance transparency in the digital advertising ecosystem. By implementing an ads.txt file on their websites, publishers list the authorized sellers, including demand-side platforms (DSPs) and ad networks, which can sell their inventory. This public declaration helps ensure that advertisers can verify the legitimacy of the inventory they are purchasing.
Combating Domain Spoofing and Counterfeit Inventory
One of the primary roles of ads.txt is to address the pervasive issue of domain spoofing and the sale of counterfeit inventory. Domain spoofing occurs when fraudsters misrepresent their sites as legitimate publishers to sell fake ad space. This not only leads to significant financial losses for advertisers but also undermines trust in the digital advertising ecosystem.
Ads.txt combats these fraudulent practices by enabling advertisers to cross-check the seller Ids against the entries in the ads.txt file. When an advertiser receives a bid request, they can verify whether the seller is listed as authorized in the publisher’s ads.txt file. If the seller’s ID does not match, the advertiser can avoid bidding on that inventory, effectively reducing the chances of falling victim to fraud. This verification process enhances the integrity of programmatic advertising, ensuring that advertisers are purchasing real impressions from legitimate sources.
Benefits of Ads.txt Adoption
The adoption of ads.txt brings numerous benefits for both publishers and advertisers, fostering a healthier digital advertising environment.

Key Components of an Ads.txt File
An ads.txt file consists of several key components that provide essential information about authorized sellers. Each line in the file typically contains the following fields:
SSP/Exchange Domain:
This is the domain name of the supply-side platform (SSP) or ad exchange authorized to sell the publisher’s inventory. It serves as the primary identifier for the seller.
Seller Account ID:
This unique identifier corresponds to the publisher’s account with the specified SSP or exchange. It is crucial for verifying the authenticity of the inventory being sold.
Relationship Type:
This field indicates the nature of the relationship between the publisher and the seller. It can be either:
DIRECT:
The publisher has direct control over the account with the SSP or exchange.
RESELLER:
A third party has been authorized to sell the publisher’s inventory through the specified SSP or exchange.
Certification Authority ID (optional):
This optional field can identify the certification authority of the seller, such as the Trustworthy Accountability Group (TAG). It provides an additional layer of verification for buyers.
Comments (optional):
Publishers can include comments in the ads.txt file, which are denoted by a hashtag (#). These comments can provide context or additional information about the inventory being sold but do not affect the functionality of the file.
Example Of Ads.txt File:
Here’s a simplified example of what an ads.txt file might look like:
Text
Greenadexchange.com, 12345, DIRECT, AEC242
Blueadexchange.com, 4536, DIRECT
Silverssp.com, 9675, RESELLER
In this example, the first line indicates that the publisher has authorized “greenadexchange.com” to sell their inventory directly, with the account ID “12345.” The second line similarly authorizes “blueadexchange.com,” while the third line indicates that “silverssp.com” is a reseller for the publisher’s inventory.
Current Adoption Rates of Ads.txt Among Publishers
Despite the clear benefits of implementing ads.txt, adoption rates among publishers have been mixed. As of recent reports, approximately 80% of the top 1,000 publishers have adopted ads.txt, reflecting a growing recognition of its importance in combating ad fraud and increasing transparency. However, many smaller publishers remain hesitant due to a lack of awareness or understanding of the benefits associated with ads.txt implementation.
Creating an Ads.txt File

Step 2: Format the File
Create a new text file and name it “ads.txt”. Each line should follow this format:
Text
<seller_domain>,<account_id>,<relationship_type>,<optional_certification_id>
For example:
Text
Google.com, pub-1234567890, DIRECT, abcd1234
Rubicon.com, 12345, RESELLER, 67890abcd
