Almost half of Facebook users say they accidentally clicking on Facebook ads at least some of the time, according to Sterne Agee in October 2012 survey results. While most of those (38.7%) overall say they only do so some of the time, 8% say they do so at least half the time. These Facebook users don’t appear to be very receptive to advertising, either. About two-thirds of respondents find the ads annoying, ranging from slightly annoying (24.2%) to moderately (19.4%) and extremely (23.1%) annoying. Still, 25.9% are neutral, describing the ads as neither helpful nor annoying. 5.7% find them slightly helpful, while no one reported finding them extremely helpful. Read the rest at MarketingCharts.
