The Local Search Hound outlines the steps toward building a review
strategy, starting with conducting simple searches (that include the word "review" and either the business type or the city name) and seeing which review aggregators come up. The top three or so will
be the ones to target.
Learning how the review process works is the next step, so the Hound encourages business owners to craft a few on the chosen sites for local businesses that they like. Then, once they're comfortable, it should be easy enough to ask their "good" customers to do a review. Over time, they should be able to collect enough reviews to create a whole new section of their Web site, not to mention the high volume of search traffic these customer comments can generate.
