A version of this discussion has come up several times in posts and comments on this blog: What is a legitimate review? Miriam Ellis offers a thought provoking post in which she suggests that a site like Yelp might remove multiple positive reviews coming from a single computer or IP address as suspicious.
The scenario she paints is this: a business owner offers a “public” computer on premises or even free WiFi and enourages people to write reviews, directly or indirectly. But the review site, in this case Yelp, might see a bunch of positive reviews coming from a single IP address and regard them as illegitimate.
Clearly if I as a small business owner pretend to be another person and write a fake review lauding my own business or if I get friends and family who are not customers to do something similar that’s “verboten.”
But what about a situation in which I provide an incentive of some kind to write a review while in my shop/shore? How about a “free cup of coffee to anyone who writes a review on Yelp?” This type of incentive was being used — as in free Starbucks cards — by a number of the early review sites (InsiderPages, Tribe, etc.) to get people to write reviews.
In my hypothetical no one is being asked to write a “positive” review, just to write “a review.” Say my program is extremely successful and suddenly (the week I start it) 30 or 40 mostly positive reviews show up. How would Yelp or another, similar site respond? If the reviews are written on-site using free WiFi Miriam’s post suggests they might raise suspicion coming from the same IP address and be removed. But should they be removed because of the incentive alone or would they if they appeared en masse in a relatively compressed time frame?
Let’s put aside the IP address issue for a second. How would my incentive program be treated? In my example these are all real people. I as the business owner haven’t asked them to say anything in particular, especially anything positive. I might even go out of my way to say “tell us what you really think, good or bad.” Yelp does explicitly address this situation and doesn’t like it either way. It asks users to disclose incentives and discourages them from writing reviews in response to such a program:
What if the business I’m reviewing gave me something for free or at a discount?
You should never accept freebies or discounts in exchange for reviews. For example, if a bar owner offers you a free drink in exchange for a 5-star review, you should not accept his or her offer.
Of course it’s ok if you were given something for free or at a discount independent of your review, but you should always disclose any special treatment, gifts, or discounts in your reivew. For example, if the restaurant manager gave you free appetizers on opening night, you should include that information in your review. Yelping is about real, honest reviews, so while we’re happy you had an extra special experience, we ask you to tell us (your readers) the whole story.
I’m in the midst of another survey of small business advertiser attitudes. To the question (also asked last year), “What do you think of online reviews?” the top response so far is “online reviews are a good thing and are helping us improve our business.” That was the winner last year as well:

As you can see we’re in a gray area ethically and philosophically with some of this behavior. But the stakes are high for local businesses, as consumers increasingly look at reviews as part of their decision-making process. In a city like San Francisco, Yelp arguably has more influence than any other single site.

What is needed is additional clarity regarding what’s permissible and what’s not (e.g., “reviews coming from the same computer will potentially be disallowed”). Most businesses will be ethical — just like most people are ethical — but they’re trying to figure all this out. I certainly don’t blame them for being creative.
