Image this: Google picks Philly's Curalate for Shop The Look

Google says it has tapped Center City-based Curalate and two other firms, LiketoKnow.it (of Texas and London) and Polyvore (Sunnyvale, Calif.) to link online images -- that aren't obviously ads -- to products and purchasing, through a mobile retail "discovery" service, which the search engine and online advertising giant calls "shop the look"

As with Google Shopping, "retailers will be charged on a cost-per-click basis... We're currently testing the shop the look experience in the US on mobile devices. If you're a retailer and interested in showing your products within the shop the look experience, create a Shopping campaign and ensure you optimize your bids to show on mobile."

Curalate counts Crate and Barrel and more than 800 other retailers as clients. The Philadelphia-based firm, which employs 160, also has offices in New York and Seattle. (corrected)
