App-ads.txt is a crucial step in helping brands realize the potential of the in-game environment

Leading mobile monetization and marketing company ironSource announced a milestone in its implementation of the app-ads.txt protocol, reaching a validated audience of over 300,000,000 daily active users. ironSource achieves this reach through partnerships with the world’s leading gaming publishers, representing one of the largest pools of available verified in-app inventory.

While research has shown that fraud is significantly less prevalent in-app than on the mobile web, over half of advertisers limit their mobile in-app investment based on fraud fears. App-ads.txt allows advertisers to know who is and isn’t authorized to buy and sell specific in-app ad inventory, reducing potentially fraudulent activity, and easing their concerns.

Working closely with the IAB Tech Lab during the beta period, ironSource has made the implementation of app-ads.txt a priority initiative to help publishers and developers using its ad network to gain the trust of brand marketers and increase ease of accessibility to their premium inventory. As one of the largest platforms managing in-app video inventory, ironSource’s emphasis on app-ads.txt implementation will accelerate the adoption of the protocol globally.

“The in-game environment provides brands with a unique opportunity to connect with consumers when they are fully engaged and receptive to advertising, and app-ads.txt is a crucial step in helping brands realize the potential of this medium,” says Amit Halperin, VP Brand Solutions at ironSource. “We’re proud to be working with thousands of game publishers around the world to encourage the swift adoption of app-ads.txt and create a safer, cleaner ecosystem for everyone involved.”
