I was looking to upgrade the way my customer reviews looked on my site and found the site powerreviews.com. Problem is that it's a tad bit pricey and kind of unfair that they get only their reviews on the search engine (at least I can't figure out how they do it).
Pretty much what I want to ask is there any addon I can use where when I search for the product on Google it will show up with stars under it. By that I mean if a set of customers reviewed one of my items and it got 4.5 stars it would show the same on Google.
EXAMPLE: When you Google one of the products that Staples sells (they use power reviews) you will see stars below their listings.
