While the top multi-platform properties overall were similar to the top desktop properties, there were several companies that jumped up the list when mobile traffic was included.
Google Sites, Yahoo Sites, and Microsoft Sites were the top three properties when it comes to both total digital population and desktop only. Of the three, Yahoo sites saw the greatest incremental percentage gains from mobile, at 16%.
Sites including Apple Inc., Pandora, Zynga, and Groupon jumped up the list thanks to added mobile traffic. Apple came in as the #8 top property, with 115.9 million visitors in total, including 40.6 million mobile-only visitors. Without mobile, the company would have been the #12 top property, behind Demand Media.
The Media Metrix Multi-Platform "combines comScore’s flagship products to accurately account for unduplicated audiences across the desktop, smartphone, and tablet platforms," said Jeff Hackett, EVP of comScore, in a statement about the top 50 properties. "This unified view of digital audiences not only establishes a new measurement standard for the industry, but also has the potential to unlock insights that can deliver substantial, currently unrealized value to our publisher, advertiser, and agency clients."
