Google Adds Ad Injector Filter In DoubleClick Bid Manager
In fight against ad injectors, Google says it has blacklisted 1.4 percent of ad exchange inventory in DBM.
To combat ad injectors, Google has added a filter on DoubleClick Bid Manager to automatically keep advertisers from buying injected ad inventory across the exchanges it has access to.
Google says it has already received nearly 300,000 complaints in 2015 from Chrome users about ad injectors.
Ad injector programs can take over legitimate ad placements or put ads in places that are not designed for ads at all. Google provided the example below showing a scam ad injected on the New York Times site, complete with a pop-up. The programs often end up on users’ machines through malicious ads or as part of software bundles.
Google says the filter in DoubleClick Bid Manager was put into place a few months ago and has blacklisted 1.4 percent of the inventory on exchanges that DoubleClick Bid Manager has access to. It’s found some exchanges have a far greater percentage of injected ads getting filtered than others. The filter prevents DoubleClick systems from bidding on the blacklisted inventory.
Earlier this year, a Google study shed light on the web of operators involved in spreading ad injection throughout the advertising ecosystem and found that over 3,000 advertisers, including major brands, have been victims.
