American Search Advertising Click Behavior by Region & Age, January 2013 [CHART]

22% of online Americans say that they click on search engine ads, finds The Search Agency in a survey conducted by Harris Interactive. The results show a fairly significant degree of variation on a geographic level, with the proportion saying they click on search ads far higher in the South (29%) than in the Northeast (20%), West (19%), and Midwest (17%). The study also finds that 18-34-year-olds report being more likely to click on search ads than those aged 35 and older (30% vs. 18%).

That result differs from earlier research from GroupM UK and Nielsen, as reported by Econsultancy, which found that the likelihood of clicking on a paid search ad increased alongside age. Read the rest at MarketingCharts.
