OPW -- Feb 25th -- If you're thinking about doing radio advertising, check out this study. Ad recall was dramatically enhanced in a study (27% vs 6%) when a mix of Radio and Internet ads was used compared to website ads alone. 'Radio ads can also improve website traffic and a brand's emotional bond with consumers when added to Internet exposures.' Radio advertising is hairy ground for most internet dating companies but eHarmony, Match and Cupid.com are making it work. Would I recommend it to the average dating company...no! But for established brand players...radio advertising is worthwhile.
