Google Launches Double Click Ad Exchange

By Robert D. Hof

Google is about to launch its most potent weapon to date in the battle over the $15 billion market for display ads—the pictorial banners and videos that support most major Web sites. On Sept. 18 the search giant will launch its new DoubleClick advertising exchange, a sort of stock exchange for online ads it has been developing since early last year.

Google’s (GOOG) exchange lets Web sites offer space that ad agencies and online brokers called ad networks can bid for in an automated auction system. Advertisers hope to get a wider choice of ad space and the ability to target ads more precisely to the most likely prospects. Publishers hope to net higher rates than they can from the hundreds of ad networks—which generally pay very low rates—and sell more of the ad space that today goes unsold. As BusinessWeek reported three months ago, Google’s ad exchange has been widely anticipated because of the company’s growing influence over online ads.

The goal for Google is to make display advertising, which currently requires a lot of time and effort to create and distribute on thousands of sites, much simpler to deploy so that many more advertisers and publishers can run the ads. Because of the existing complexity, as well as advertiser uncertainty over display ads’ effectiveness, text search ads such as Google’s have grown far faster than display in recent years. “The idea is to grow the overall display-advertising pie,” says Neal Mohan, Google’s vice-president for product management. “Display advertising is still not living up to its full potential.”

It’s far from certain that Google will succeed with its new exchange. The giant dominates the market for search advertising, garnering about half the industry’s total revenues. But it has struggled to expand into new fields, such as radio and print advertising, and its efforts in display ads have seen little success so far. Search ads still constitute over 95% of Google’s revenues. The company’s display-ad exchange, an early version of which Google picked up early last year when it acquired online ad-placement firm DoubleClick for $3.2 billion, will face competition, too. Yahoo! (YHOO), Microsoft (MSFT), and others already operate their own exchanges.


Google has one big edge, though: Nearly all of the major Web publishers already use DoubleClick’s services. Ad agencies hope those publishers, whose large audiences they find attractive, will make more of their premium ad space on frequently visited pages available on DoubleClick’s exchange. To prime the exchange pump, Google is making ad space on hundreds of thousands of other sites on its Content Network, where it already places search ads, available through the exchange. “They have an enormous advertising base that will make the marketplace liquid,” says Marc Goldberg, vice-president for business development at, a site that offers experts on a wide range of topics, owned by the New York Times Co. (NYT).

The ad exchange won’t have much impact on Google’s revenues any time soon, since Google takes only a tiny cut of ad revenues from the exchange. Moreover, both publishers and advertisers remain cautious about exchanges because they represent an entirely new way to buy ads. Right Media, the ad exchange Yahoo bought several years ago, is currently the leader, but even its founder, Mike Walrath, has said exchanges will take time to catch on widely.

Google’s own display efforts have proceeded more slowly than the company had hoped. Insiders say that’s largely because much of the DoubleClick software needed to be rewritten to work with Google’s ad software and computing infrastructure. At the same time, Google’s display operation has seen some high-profile departures. Former DoubleClick CEO David Rosenblatt left in April, reportedly to start his own venture. Last week, Michael Rubenstein, former director in charge of recruiting ad networks for the DoubleClick exchange, left to become president of advertising technology provider AppNexus.

Still, running an exchange puts Google front and center in another huge ad market beyond its mainstay search ads. With the launch of the new DoubleClick ad exchange, which includes a number of new features, Google hopes its display business will start to accelerate.


Google says the exchange will allow real-time bidding for advertising inventory through the use of automated software tools. A publisher may sell space its direct-sales team couldn’t sell to an ad network that offers $5 per thousand impressions, or viewings by visitors, known as CPMs. But another ad network could step in—even at the last second, using automated bidding technologies—and offer $10 because it believes it can deliver more potential customers to its advertiser or agency client. Then Google’s exchange can instantly run the more lucrative ad instead.

The draw for advertisers is that they can automate their placements to get in front of the most lucrative potential customers. A regional retailer might offer to pay $5 CPMs for a product ad to run on certain Web pages but specify that it’s willing to pay $10 if the publisher can show that ad to people in a particular geographic area in which it wants to sell a product.

The new exchange also lets advertisers and publishers that currently use Google’s search-ad systems participate in the exchange using the same software. Google isn’t naming specific publishers that are participating in the exchange, though early participants say large sites such as (WPO) and other major newspapers and entertainment sites are among them. It’s not certain how much ad space publishers will make available on the exchange. Publishers will have control over which agencies and ad networks can bid on their space and what kinds of ads they can run.

Early trial users say the exchange looks promising. Kevin Lee, CEO of search marketing firm Didit, says so far it appears to be “a step above [Yahoo’s] Right Media. We’re fairly pleased with it” because the DoubleClick exchange includes inventory from well-known sites, he told BusinessWeek earlier this year. “We like the concept of an ad exchange that gives access to these kinds of sites, and we’re willing to pay more for that.”
