Social media and search advertising are projected to be the most popular advertising tools this year, each cited by 24% of respondents to a PointRoll survey [pdf] of US marketing professionals, conducted by Kelton Research and released in March 2012. Display advertising followed closely, chosen by 22% of respondents. There was then a significant drop-off to online video (11%), mobile or tablet ads (7%), and mobile or tablet apps (6%). Just 1% chose email, text/SMS, or social gaming. Search advertising is more popular among respondents at director level or above, compared to those in supervisory or managerial positions (30% vs. 19%). Read the rest at Marketing Charts.
