Why should you read this infographic?
Because a visual makes understanding these standards much easier.
The IAB has taken a leading role in the fight against fraud in digital advertising. Their first standard, ads.txt, helps prevent bad actors from tricking buyers into purchasing fake impressions. Available on desktop and mobile web, it lets publishers declare which companies they authorize to sell their digital inventory and, in turn, works towards improving transparency.
It's follow up, ads.cert, is a digital signature on a piece of ad inventory that can be verified against a shared key. It validates the information that passes between the buyer and seller at every stage of the digital ad supply chain, and stops fraudsters from tampering with a publisher's inventory.
Take a look at our visual representation of ads.txt and ads.cert - "Fighting Fraud with Standards: Ads.txt and Ads.cert Explained".
