The advertising of the future is going online--and going local. This hot trend is growing rapidly and shows no signs of letting up. In fact, according to a report by Borrell Associates, local online advertising is expected to grow by 31 percent this year, hitting $7.7 billion. The report also predicts local paid search will skyrocket by 86 percent this year, up to $1.8 billion. Local e-mail marketing will experience growth of about 54 percent, reaching $233 million.

There's no question that consumers are using the internet to navigate their way to local brick-and-mortar retailers. A recent study by ROI Research Inc. and Performics shows that online searches influence 20 to 30 percent of purchases made at retail locations--and that number is only increasing. More and more sites, like Local.com, are making their presence known by competing against major search engines like Google and Yahoo!. So study up, plan your budget and get in on the online advertising game.
