There’s been a lot of convincing research released in the past few months around customer ratings and reviews. Clearly, web site customers find ratings and reviews useful and not only rely on them to make purchase decisions — they also participate and share their own experiences. Here are a number number of recent articles and blog posts that discuss customer ratings and reviews:

Nice to see some hard data on this subject!
Good work putting it together, Rick
I have a serious problem with the Forester survey though: It looks like they’ve directly asked the consumers, “Do you want reviews & ratings?”.
Haven’t they ever heard of “User Says, User Does”?
It’s like asking “Do you want the chance to win a 10.000$ vacation?”. 99% of all people would answer yes to that question, but when it’s competition time only 10% of all your visitors will actually enter it.

Agreed, but I let that slide by because as I’ve conducted usability tests for e-commerce sites, customer ratings and reviews get seen and read without prompting… good point, though.

We integrated them into our e-commerce site yumdrop.com and have done fairly well with them. While they haven’t upped our conversion rate as we had hoped, they’re at least providing us with valuable information about the quality of the products we carry and what our customers think of our service. Not to mention the influx of unique content that comes to us without any work on our part with each review is great too!
