Overview: What is the Ads.txt file, and why do we use it?
PLEASE NOTE: The full list of Inform's ad partners is included in the ads.txt file at the bottom of this article (please scroll down for attachment).
Inform, Inc. offers Ads.txt as a increased security measure across its entire partner-base in order to ensure more efficient advertising buying through our platform. Ads.txt is a way to 'whitelist', or pre-approve, advertising sources (otherwise known as 'Authorized Digital Sellers') that are used through Inform Player Services. As a result, Ads.txt helps protect against unauthorized ad inventory and/or 'spoofing'.
Many websites, browsers, and ad sources are requiring Ads.txt in order to validate that Inform has the rights to sell inventory on/for that specific domain. The Inform Seller IDs listed in the Ads.txt file represent the technology powering our ad delivery.
Please see the Inform Ads.txt file attached to the bottom of this article, and either add it to your HTML file structure, or copy and paste its contents to an existing Ads.txt file within your website file structure, making sure that it propagates to your DNS.
Contents of the Ads.txt File
Spec for the Ads.txt file may be found in the IAB Ads.txt Document (also attached in PDF), more specifically pages 3-6 of this document. IAB explains that the document should be a formatted plain test document, with lines consisting of:
"A non-empty set of records, separated by line breaks. The records consist of a set of lines of the form
<FIELD #1>, <FIELD #2>, <FIELD #3>, <FIELD #4>"
The fields represent the following ad source characteristics: (1) Domain Name of Advertising System, (2) Publisher's Account ID, (3) Type of Account/Relationship, (4) Certification Authority ID.
