It has been a while since the IAB Tech Lab has introduced ads.txt whose intent is to protect the advertising inventory and to repel the programmatic types of ad fraud. It is providing a transparent ecosystem in the programmatic advertising industry.
Even though the ads.txt initiative is not new, there are still opportunities for further enhancements. Publishers are still hesitant about the ads.txt initiative because they are not fully aware of all the benefits it can bring or think it is too complicated to implement. According to Alexa data, today more than 56% of publishers have not implemented ads.txt.
In this article, we want to give you a brief overview of ads.txt, sharp implementation practices in Wordpress, and AdSense platforms and core benefits for publishers and advertisers!
What is ads.txt?
Ads.txt or so-called Authorized Digital Sellers is designed to reduce ad fraud types as domain theft or alleged domain hijacking. Ads.txt increases the transparency of the publisher’s ad inventory by knowing where impressions are purchased and resold.
Ads.txt is a text file, which gives control to publishers to authorize who's allowed to sell ad inventory, preventing fraudulent practices in unauthorized inventory sales. It is a simple method that combats online ad fraud by merely listing the publisher's authorized ad inventory sellers. Ads.txt allows ad buyers to validate the sellers, that is why they can avoid unauthorized traffic sales.
How does adx.txt work?
The publishers add the adx.txt file on the website, confirming the ownership of the domain and indicating the partner accounts which are eligible to sell their ad inventory. As a result, the advertisers can easily search the web and receive a list of all the authorized publishers and provided ad inventory.
Answering the question of how to verify the content, the answer is relatively simple.
When the advertiser receives a bid request from the publisher, the advertiser can easily check if the publisher is legit. All the advertiser has to do is to match the publisher's account ID with ads.txt file. And if everything matches the advertiser can feel confident that the publisher is an authorized dealer. On the other hand, if the buyer finds out that the publisher's ID is not validated, the buyers can make a decision not bid on the particular publisher's inventory.
How to create ads.txt in Wordpress?
