Recently there has been a great deal of discussion about applications that inject or overlay ads on sites without the express approval of users and those sites, and then monetize the inventory as their own. We believe that this kind of activity is bad for end users and damages the integrity of the advertising industry. In order for the programmatic marketplace to achieve its full potential and help as many marketers and publishers as we think it can, there needs to be trust between advertisers, publishers, and users.

We’ve invested, since the beginning, in strong policies and a system of checks and filters to ensure that the inventory on the DoubleClick Ad Exchange is the highest quality in the industry. Here’s a quick summary of what we do to stop invalid injected inventory from entering our exchange.

We don’t support spammy applications. Period.
Both the Google Platforms program policies and the DoubleClick Ad Exchange (AdX) Seller Program Guidelines strictly prohibit the use of systems, including toolbars, that overlay ad space on a given site without express permission of the site owner. In addition, we have numerous processes and technologies in place to review publishers’ inventory as well as advertisers’ ads to maintain a high standard of quality for how advertising is transacted on our platforms. 

In light of the increased concerns on this subject, many publishers have asked us for guidance on what to ask the exchanges or networks they work with. Here are three suggested questions any publisher partner should be able to answer in regards to protecting against injected inventory:
  • Does your platform work with or supply advertising for clients who inject display ads in browsers?
  • Do your program policies prohibit the use of systems to inject display ads in browsers, without first having obtained user consent or consent from the site affected?
  • Please provide me a report of all the inventory partners on your platform serving my domain?

We do, and will always, support our publisher partners. 
Finally, I’d like to thank the millions of publishers who use the DoubleClick Ad Exchange, large and small, that day in and day out, provide amazing value both to their users and their advertisers. We welcome a broader discussion with our partners and with the industry about how to collectively solve this issue and others. Together, we can all ask the tough questions, hold each other accountable, and ultimately create the web we all want, where publishers, users and advertisers all thrive.
