The feds are coming after Google. In January, the Department of Justice filed an antitrust lawsuit alleging that the technology giant monopolized the lucrative space of digital advertising. A sure-to-be exhaustive trial underway in the U.S. District Court in Washington is expected to last until November.
The lawsuit focuses on three key players: advertisers, publishers and vendors of ad tech tools that match publishers with advertisers and orchestrate ad targeting and delivery. However, monopolization also affects another key group that remains largely unprotected by U.S. laws: you and me, the end users.
Google's dominance has led to a singular method of how ads target us, and we've been left with little choice and no legal safeguards in the current setup.
Many of us are familiar with incessant social media ads on Facebook and Instagram. That's called "closed web" advertising and is operated in-house by those companies. But how does digital advertising on the "open web" work, say, when we search Google?
As explained in the Justice Department complaint, the process begins when the user opens a publisher's website that's programmed to show personalized ads. During the short time that the website loads, an automatic auction takes place on an ad exchange to determine which ads to show to the user.
The ad exchange receives information about the website and the user from the publisher, supplements it with any additional information it may have about the user's demographics, location, interests and web browsing history, and then matches it against bids from the advertisers. The more information the ad exchange has about the user, the better it is able to personalize the ads and then maximize the likelihood that the user will click on an ad, and ultimately buy the product or subscribe to the service.
