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."
