What is Google Boost? Think of it as combing your Google Places account and your Google Adwords account into one product. The idea is to focus on local result searches.
My initial opinion on Google Boost is a wait and see approach. The reason is that more control is turned over to Google. Control over your marketing budget, control over keywords, control and limitation of content. Adwords gives you greater flexibility over all of the aforementioned items.
Still, if Google sticks to it's pledge of "Don't Be Evil", Boost could be a viable option for small businesses. In other words, the jury is still out. Here at Semiam Solutions, we will keep you updated on Google Boost. When the time is right, we will help you take the plunge.
