Ad Network Differentiating Factors

Data is also improving. But because it is also becoming more of a commodity, the real question will be whether this data can be proprietary.

Where will the next ad network breakthrough come from? « Lightspeed Venture Partners Blog

The question asked by Jeremy Liew is a great one and the post is worth reading. I’d have to add that one of the things ad networks overlook is actual metadata on the sites, placements and pages that are part of the network. 

This data is hard to collect, it’s hard to categorize and it’s even harder to make use of given the legacy ad servers they all use (hello DoubleClick), but this would allow networks to create other, new vectors of targeting. 

Imagine the ability to target a campaign based on how many ads there are on the page? Or whether the placement is above or below the fold? Or based on how prominent the placement is on the page versus content? How much time on average people spend on that page? All these criteria warrant a premium that advertisers would gladly pay. 

Since inventory is abundant, you have to separate the good from the bad and treat is accordingly on the sell side. Ad exchanges don’t solve that problem, but ad networks are well positioned to differentiate themselves this way. The same goes for publishers too, of course.
