Speaking of SMB marketing: A rather large concern, Google, began to throw its weight around in local business advertising this year. In April, it re-launched its local products as Google Places, which includes free listings for businesses. In October, it added Boost to the mix, offering (in select cities) paid, localized search on maps and in other results. (Boost's pilot launch just happened to coincide with Microsoft's announcement of a unified account platform for Bing and Yahoo! advertisers.) Most recently, Google has taken to the streets -- actual, physical streets! -- of Portland, OR, with a marketing campaign that will put its new local recommendation engine, Hotpot, to the test.
