Zynga (NASDAQ:ZNGA) +2.1% AH, LinkedIn (LNKD) +1.7%, and YELP +1.5% after Facebook blows away Q2 estimates courtesy of a 75% Q/Q increase in mobile ad sales. Facebook's Payments & Other revenue (relevant to Zynga) rose slightly Q/Q and 11% Y/Y in the face of a shift in gaming activity towards mobile (where Facebook doesn't get a 30% cut). The mobile ad growth comes as LinkedIn begins rolling out Sponsored Updates, a news feed ad product very similar to Facebook's popular Sponsored Stories. Zynga reports tomorrow, Yelp on July 31, and LinkedIn on Aug. 1.
