Yelp rival, ReachLocal, Files for an IPO

Founded in 2003, ReachLocal has built a platform that helps small and medium size businesses (SMBs) create effective online media campaigns. Some of the services include: connections with search engines, directories and ad networks; keyword provisioning; bid management; and tracking. To scale its business, the system is highly automated and is currently managing tens of thousands of campaigns. The pricing ranges from $500 to $3,000 per month.

Yet, there is still some old-school approaches. For example, ReachLocal has a "feet-on-the-street" direct sales force that includes 438 employees.

But the formula is getting results. For the first nine months of 2009, revenues came to $143.3 million, up 37.5% from the same period a year ago.

And, it looks like the local online advertising market is still in the early stages. According to Borrell Associates, SMBs spent about $60.5 billion on local advertising last year.

In light of this, it's clear why Google -- and other top Internet operators -- want to get into this space.
