Over the years, we’ve found that maximizing competition for every impression produces the best results for you. That’s why we’ve developed new Custom and Flexible Ad Size controls in DoubleClick Ad Exchange to bring you even more competition for every impression so you can sell any ad size programmatically.

Maximum demand for all ad sizes

Region-specific ad sizes have always been difficult to monetize programmatically because they typically do not match IAB standard ad sizes. Now with Custom Size controls on DoubleClick Ad Exchange publishers can easily create and sell ads of any size programmatically. For example, in Northern Europe where the 800x250 ad size is popular, publishers can now benefit from the programmatic demand of Ad Exchange with all the controls and reporting they’re familiar with.

In addition to making it easier to implement Custom Sizes, we’re making it possible to increase the demand available to every ad with Flexible Size controls. Publishers can now allow any ad slot to accept bids from multiple ad creative sizes. For example, a custom size slot like 320x300 can now be filled with popular sizes like 300x250 and 250x250 in addition to exact 320x300 matches. Flexible Ad Sizes is now live on all ad slots for publishers globally and publishers can control the range of sizes their slots accept with the Flexible Size rule type.

With Custom and Flexible Ad Size controls publishers globally can sell ads of any size and maximize yield for them with programmatic demand. During testing, we observed a revenue increase across all Ad Exchange inventory with some publishers seeing CPM gains as high as 30% for affected ad slots.

"Custom Ad Sizes has enabled us to move the bulk of our programmatic deal making to DoubleClick Ad Exchange, which has simplified things a lot. The Finnish market is very much dominated by market-specific ad sizes, especially 980x400 and 300x300."

Since its launch in 2008, HTML5 has quickly gained widespread adoption and is now becoming the standard for developing digital creatives. The advertising industry is responding, and increasing numbers of advertisers and agencies are building HTML5 creatives.

If you’re a publisher, this means you’ll want to make your site HTML5-ready and help advertisers get up to speed on developing these new creatives. We know the transition from Flash to HTML5 will require some short-term work on your part, but we’re here to help you and advertisers with the process.

What’s so great about HTML5?

HTML5 has seen high adoption rates for a number of reasons.

One key to its popularity is that HTML5 offers strong cross-device support—the language works well on a variety of browsers and mobile devices. This is hugely important now that more people are searching on mobile devices than on desktops.

HTML5 also plays higher-quality video faster—with an average bandwidth reduction of 35 percent. YouTube notably began defaulting users to its HTML5 player this January.

Browsers have taken note of HTML5’s speed and other benefits and have begun introducing power-saving plugins and reducing support for Flash. To increase page-load times, Chrome recently began auto-pausing Flash content that is not a primary part of a page. Safari had already done this and Firefox blocked Flash from auto-loading in July.

Getting ready for HTML5

With the web moving quickly in the direction of HTML5, here some steps that you, as a publisher, can take to prepare for this transition:

  1. Update your creative specifications: Explicitly include HTML5 as a supported technology and increase associated file-size limits to support large HTML5 creatives.
  2. Educate advertisers: Share the benefits of HTML5 and provide HTML5 creative specifications to your advertisers so they can build creatives that work on your site.
  3. Train your teams: Educate your team about HTML creative specifications and let them know what to do when they receive HTML5 ads from advertisers.
  4. Assist advertisers: Share free HTML5 ad conversion and creation tools with advertisers to ease their transition to HTML5.

All of this and is covered in our new guide to help publishers move to HTML5. If you’re looking for more information as you’re transitioning to HTML5, check out the HTML5 resources and HTML5 Toolkit on the Rich Media Gallery.

Also, our Doubleclick Rich Media team is kicking off an HTML5 Hangout series, where over five weeks we’ll set aside an hour to explore topics ranging from how to QA HTML5 ads to building dynamic creative (See the complete Hangout schedule). The first hangout is on September 10th (3pm - 4pm EST) and will introduce you to HTML5 development tools and best practices. Register here.

We know that change can be hard, so we want to make your move to the future of digital advertising a bit easier.
