Google to Require App-ads.txt Authorization for Device-Based Ads

Sadly, no discussion of digital advertising can avoid mentioning fraud. It’s still a huge problem but the industry is fighting back. The latest thrust comes from Google, which has announced its mobile ad platforms AdMob and Ad Manager will only serve ads that publishers have authorized by listing the seller in an app-ads.txt file. App-ads.txt and big sister ads.txt have been among the most successful anti-fraud measures.
