Any help...helps :))
I would stay away from BazaarVoice or any similar products where your ratings are hosted on another company's server. BazaarVoice makes you pull their content into your pages using iframes, so in search engines, you get zero credit for those ratings - you're boosting BV instead. Anything you can keep on your own server will load faster and be credited to your benefit. Try to look for one that uses Schema.org or some other type of microdata which the search engines will understand - then you may even get fancy star ratings right in Google search results.
I could have "our people" build one but I would rather not. I'll check out schema - i've looked at it in the past when doing Google Analytics research so I'll keep an out!
