One of the most frequent warnings we see in Google Ad Manager<\/a> is the yellow bar across the top of the page\u00a0 stating Warning<\/span>\u00a0<\/em>–\u00a0Please review your ads.txt setup to prevent potential revenue impact<\/em>.\u00a0 Such high-impact warnings are always a concern and no publishers wants to risk “potential revenue impact”, but the help that the warning links to does not always help to resolve the issue.\u00a0<\/span><\/p>\n

\"ad<\/a><\/p>\n

Ads.txt is the initiative to give buyers confidence that the ads they are buying are being displayed on the website that they claim to be. The idea is simple: Each website declares what accounts are authorised to sell on their behalf by listing those accounts in a text file on the site. This file sits in document root and is named ads.txt. We discuss implmenting ads.txt for AdSense and Ad Manager in this post<\/a>.<\/p>\n

What does the warning mean?<\/h2>\n

When Google Ad Manager believes you are serving Google Ads on a domain that has not authorised the account then it will display the warning “Warning\u00a0–\u00a0Please review your ads.txt setup to prevent potential revenue impact”.\u00a0 Google will look for a line in each ads.txt file authorising each linked account that is serving ads to that domain. If it is unable to find and understand any of those lines then the “Please review your ads.txt setup” warning is shown.<\/p>\n

What can the potential revenue impact be?<\/h2>\n

Google ads (meaning AdSense<\/a> and Ad Exchange<\/a> ads) will only be shown on domains with the appropriate ads.txt authority. This means that no revenue will be generated from Google ads for that combination of domain\/account until the issue is resolved.<\/p>\n

My file looks fine – why the warning?<\/h2>\n

There are a number of reasons why Google Ad Manager may not find the authority it requires:<\/p>\n
