Online peer reviews do sell things…up to a point
Here’s an interesting report, from our very own University of California at Berkeley, as reported in the San Francisco Business Times: “[G]ood online reviews on Yelp do indeed bring in more customers.” Specifically, “a half star rating increase (1 to 5 scale) meant a 19 percent greater likelihood that a restaurant’s seats would fill up during peak hours.”
The researchers did not have an explanation for this phenomenon (which actually has some important limits, which I’ll get to in a minute), but I do. Now, I’m one of those people who likes and depends on restaurant reviews. We have a ton of restaurants here in the San Francisco-Oakland-Berkeley area, of all types, at all price levels, from just about every ethnicity in the world. So it can be confusing and intimidating to decide on a new place to eat. Under the circumstances, I’ll often turn to two sources for recommendations: Yelp, and the San Francisco Chronicle’s great restaurant reviewer, Michael Bauer. A bunch of great Yelp reviews is enough to persuade me to try someplace out, while a single Bauer “must eat there” does the same thing.
I think that’s the reason why Yelp reviews work: people, like me, believe in peer recommendations (such as Yelp’s) and also in expert reccos (such as Michael Bauer’s). Of course, just 1 or 2 glowing peer reccos for a particular place won’t work for me (or anyone else, I should think), because they could always be from the owner’s cousin and mother. And 1 or 2 glowing reviews won’t do it at all, if they’re negated by 6 or 7 “worst experience of my life,” “would never go back there,” “AVOID AT ALL COSTS!”
But one great Michael Bauer review will send me to the joint. I guess, to my way of thinking, there is an emerging parity between expert reviews, on the one hand, and peer reviews, on the other, but that parity only works if the peer reviews (such as Yelp’s) are overwhelmingly positive. So Michael Bauer isn’t going to have to look for a new job anytime soon. When it comes to food, people still depend on restaurant critics. (At least, in a foodie town like Ess Eff.)
I mentioned above that the U.C. Berkeley study had important limits:
(1) “For restaurants with Michelin stars, for example, the Yelp reviews were irrelevant.”
(2) “Restaurants that were rated in popular guidebooks or newspaper rankings got less of a Yelp bump. They ‘did not see a statistically significant effect from the Yelp rankings,’ the economists said.”
Let’s take (2) first. This just confirms my own reasoning: I’ll take Michael Bauer over Yelp 95% of the time. Even if there were positive Yelp reviews, one critical Bauer review canceled them out. Call me old-fashioned, but I still believe experience counts over simple enthusiasm (such as the type you see on Yelp and, for that matter, on “Check, Please!).
As for (1), my hunch is that the kind of people who review restaurants on Yelp probably don’t frequent Michelin restaurants. Why not? They’re too expensive; the people who eat at French Laundry, Coi and Benu are not likely to post their experiences on Yelp, and the people who are considering eating at French Laundry, Coi and Benu are not turning to Yelp for advice.
You just knew I was going to make a connection to wine reviewing, didn’t you? Well, I am, and here it is: Inexpensive wines are more likely to see spikes in sales from online social media sources, such as blogs and Twitter. Expensive wines are not, because the kind of people who can afford them don’t blog or tweet, and if someone has enough money to buy, say, Shafer Hillside Select ($230 for the just released 2008), they couldn’t care less what some blogger has to say.
However, that well-heeled person considering buying the Shafer does care what the Michael Bauer-equivalent of the wine critic has to say about it. I’m not saying who that equivalent is (wouldn’t be prudent, not opening that can of worms), but I’m reviewing the ‘08 Hillside Select tomorrow, and if I give it a good score, I wouldn’t be surprised if it has an impact on demand.
