With the launch of a new "holistic" reporting product, comScore hopes to provide more value in the metrics it supplies advertisers, reports Mediaweek.

The Ad Metrix Publisher will give advertisers a holistic view of campaigns, with impressions and age groups that span ad units, as well as audience demographics for entire categories of sites. The new reporting is meant to give buyers numbers that more closely match what they can get from print campaigns, something they have been clamoring to get from the online world.

Buyers can use the numbers Ad Metrix provides, comScore says, to better place ads by locating target audiences more efficiently and making appropriate adjustments. The company says it's the first product on the market to bring such a long-range view tool to buying, as well as one that more accurately shows who in the audience has seen which ads.
