It’s now clear that investments in new technologies, new ad formats and improved buying and selling processes are helping to grow the display advertising pie. This benefits publishers who make more money from display ads, users who receive free ad-funded content and marketers who are able to grow their businesses online.

However, we often hear from major website publishers that ad management today is still mind-numbingly complicated and inefficient. We’ve been investing in our publisher tools to try and improve this landscape and have made great progress, but we think we can do even better. To help major publishers get the most out of the rapidly changing and growing display ad landscape, we’ve signed an agreement to acquire Admeld, a New York-based yield optimization firm.

Here’s a basic summary of the display ad industry, from the perspective of major publishers. There are lots of different ways that they can sell their display ad space. Often, they’ll sell space directly to advertisers or agencies, using an ad server to actually deliver and measure the ads (like Microsoft’s Atlas, AOL’s AdTech, DoubleClick's DFP, Yahoo’s APT, OpenX, Zedo, 24/7 Real Media and others). Alternatively, they’ll make their ad space available indirectly—to hundreds of ad networks (like Advertising.com, Specific Media, Collective, 24/7, ValueClick, Vibrant, AdSense, Undertone and others), each with thousands of advertisers, or to various advertising exchanges or technology platforms (like Yahoo’s Right Media, OpenX, DoubleClick Ad Exchange, ContextWeb, AdBrite, AppNexus and others) that match them with ad buyers (like ad networks and demand side platforms) who represent advertisers, in real-time marketplaces.

Some publishers also work with a “yield optimization” provider (such as Rubicon Project, Pubmatic and others) that supplies technology to select ads from across these many indirect options, while providing personalized service and support. In a very complex and rapidly growing display ad landscape, that’s what Admeld does.

Providing better ad management services to publishers is an area that has seen a huge amount of investment in recent months. Formed just over three years ago, the Admeld team is an example of the huge strides the industry is making—it has quickly developed a great service that is helping many major publishers manage their ad space more efficiently and profitably.

By combining Admeld’s services, expertise and technology with Google’s offerings, we’re investing in what we hope will be an improved era of flexible ad management tools for major publishers. Together with Admeld, we hope to make display advertising simpler, more efficient and more valuable, provide improved support and services, and enable publishers to make more informed decisions across all their ad space. These are all things our publisher partners have been asking us to further invest in. Of course, Admeld will continue to support other ad networks, demand side platforms, exchanges and ad servers, to yield the best possible results for publishers.

We believe that this investment will be an important step to help online publishers, and will further improve and grow the display advertising industry as a whole.
