Are you a blogger or a website owner? You might have got the notification on your AdSense dashboard warning for not implementation of the ads.txt file to their blog/website. The Ads.txt initiative was started to combat ad fraud and in particular, two main types – unauthorized reselling of your ad inventory through arbitration, and more importantly, ad fraud through misrepresentation or counterfeit ad impressions.
What is Ads.txt?
Similar to the infamous Robots.txt file, it’s a “plain text” file that is hosted on your root domain, at the top level of your website, and it contains a list of authorized sellers of your advertising inventory. It is case sensitive code so do not modify the basic structure of the code. Don’t put semicolon replacing comma or small letters for DIRECT/RESELLER tag.

Now, Let’s break down this ads.txt file info.
The domain name of the advertising system (required to be in the ads.txt file). For Google seller accounts, the domain name is always google.com. The canonical domain name of the SSP, exchange, header wrapper, etc. system that bidders connect to. This may be the operational domain of the system, if that is different than the parent corporate domain, to facilitate WHOIS and reverse IP lookups to establish clear ownership of the delegate system. Ideally, the SSP or exchange publishes a document detailing what domain name to use.
The publisher’s account ID (required to be in the ads.txt file). The identifier associated with the seller or reseller account within the advertising system in field #1. This must contain the same value used in transactions (such as OpenRTB bid requests) in the field specified by the SSP/exchange. Typically, in OpenRTB this is the publisher.id field. For OpenDirect, it is typically the publisher’s organization ID.
Type of account/relationship (required to be in the ads.txt file ). An enumeration of the type of account.
A value of ‘DIRECT’ indicates that the publisher (content owner) directly controls the account indicated in pub-0000000000000000 on the system in google.com. This tends to mean a direct business contract between the publisher and the advertising system.
Google publishers who directly control their publisher account that is pub-0000000000000000 should specify ‘DIRECT’.
A value of ‘RESELLER’ indicates that the publisher has authorized another entity to control the account indicated in field #2 and resell their ad space via the system in field #1. Other types may be added in the future. Note that this field should be treated as case-insensitive when interpreting the data.
Google publishers who do not directly control the account indicated in field #2 should specify ‘RESELLER’. For example, an Ad Exchange account using Network Partner Management should specify ‘RESELLER’ for inventory the account doesn’t directly manage.
Certification authority ID (optional). For Google seller accounts, the TAG ID is f08c47fec0942fa0. An ID that uniquely identifies the advertising system within a certification authority (this ID maps to the entity listed that is here in this case is the google.com). A current certification authority is the Trustworthy Accountability Group (TAG), and the TAG ID would be included here.
greenadexchange.com, 12345, DIRECT, AEC242
Where greenadexchange.com is the domain of the advertising company and 12345 is the publisher id. As a direct contract between the advertisers and publishers, it is mentioned DIRECT and AEC242 is the ad company code which is optional. Similarly,
blueadexchange.com, 4536, DIRECT
silverssp.com, 9675, RESELLER
ads.txt direct vs reseller
DIRECT is the direct contract between advertisers and publishers. Google provides DIRECT ads through AdSense Programme. Some other companies like Mediavine they buy ads from Google and act as Reseller in this case.
