Local Online Advertising to Nab $7.8 Billion by 2011, released by eMarketer today, sheds light on how far local advertisers have to go to reach their increasingly online audience. While the revenue crunch for newspapers and the stagnant state of the radio industry (overtaken by online this year in the US) is due to national advertisers moving their budgets online, $97 billion is still spent on offline local advertising. In many markets, the decline in offline usage is far outpacing online growth. The current projections look mainly at display and search ads, and rightly so, as they make up the lion’s share of local advertising options currently. But one would think that in the near future, a bevy of new options will be open to smaller businesses. Local bloggers are growing their audiences by leaps and bounds, with restaurant reviews, local events, community news, etc., and smaller businesses are usually a key component of the neighborhood. A blogger relationship program is low cost and high impact, especially when the marketer is a known personality. Likewise, when mobile finally finds a way to use GPS-enabled ads on a wider scale, the threat to radio potentially becomes much greater. While the barrier to entry with these mediums is more knowledge/comfort than financial, it is only a matter of time before spending accelerates to catch consumer adoption.
