This week’s blog post from Cumulus Media | Westwood One’s Audio Active Group looks at the effects of reach on and advertiser’s “mental availability.” The piece quotes authors Les Binet and Sarah Carter from their book, 66 Ways To Screw It Up: How Not to Plan, “The single most important factor driving brand preference is ‘mental availability’: how well known a brand is, and how easily it comes to mind. Brands with low mental availability tend to struggle, rejected in favor of more familiar rivals. Or not considered in the first place. Brands with high mental availability don’t have to push so hard to sell, so tend to have higher market shares and better margins.” The authors also advise, “Always aim to get more customers from all segments of the market. It’s the main way brands grow.” The blog post concludes that AM/FM radio makes your media plan better by increasing reach. One example is illustrated as follows: Edison’s “Share of Ear” study of ad-supported audio reveals the combined persons 18+ daily reach of Pandora and Spotify is only 12% of Americans. Adding podcasts causes reach to surge to 29%. The introduction of AM/FM radio lifts daily reach to 74%. See the full blog post here.
