In the initial days of the release of the ads.txt, only 13% of the 10,000 most popular domains that sell digital ads adopted ads.txt.
However, With Google announcing that its DoubleClick Ad Exchange (now Google Ad Manager), AdSense Network and DoubleClick Bid Manager (Google’s DSP) will begin using ads.txt files to filter unauthorized inventory, there was a huge spike in the number publishers who have implemented ads.txt on their websites in the last few weeks.
Between mid-September and the end of October, that number jumped to 44 percent, according to the to data from Ad Ops Insider publisher Ben Kneen.
Why is it important to verify your ads.txt file?
The principle behind the ads.txt is to prevent spoofers from siphoning millions of ad dollars from the ad tech ecosystem. So, it requires authentic publishers like you to say who are the authorized sellers. This, in turn, help buyers to buy your ad inventory at the right place.
Exchanges selling spoofed inventories won’t receive any bids and authentic SSPs and ad exchanges which have real relationships with publishers receive the bids ensuring the amount goes to the actual publishers.
At the end of the day, your bottom line will stay protected. As syntax errors are reportedly the most common form of ads.txt errors, we launched a tool to help you validate ads.txt files – Verify ads.txt.
