Fixing Spelling, Grammar Of Customer Reviews Boost Revenue. But Will It Backlash?

Written by Evan Schuman
May 4th, 2011

Virtually every E-tailer today embraces the sales-increasing power of customer reviews—and almost no one thinks that tampering with those comments is a wise move. But a recent study from New York University throws a delicious new nuance into the discussion, having found that cleaning up the grammar and spelling of posted comments can sharply increase their sales impact.

The premise that consumers would find more articulate and intelligent-sounding comments more persuasive is as logical as it is disconcerting. It’s disconcerting in that it reopens the “should we change the comments in any way and, if we do, how far should we go? And, who should do it and what should the rules be?” debate. Is the boost in sales worth the higher copy editing costs? Are automated systems (Zappos has been using Amazon Mechanical Turk for just such an effort) sufficiently accurate? Here’s a frightening one: If you go the copy edit route, are you obliged to do it for all comments? What if you only cleaned up the positive reviews, leaving the negative ones verbatim, hoping the typos and poor grammar will dissuade other shoppers from being discouraged from buying?

The psychological approach-avoidance relationship E-tailers have had with user comments/reviews is legendary, whether it was Etsy toying with anonymity rules, Guitar Center paying for comments, Topix trying to charge for dealing with some comments or even Costco accepting them at all. Of course, attempts to game the comment system are nothing new, with Belkin probably the most blatant case. One marketer even tried gaming our comments system, until an IP address exposed the scheme.

The editing approach suggested by NYU is different, though. It doesn’t get into changing the essence of what the user said—and it certainly does not promote the idea of publishing only favorable reviews, which often has the opposite impact because it sharply dilutes the credibility of the favorable reviews. No, this approach can be seen as merely doing the commenter and other customers a favor, in that almost everyone likes having their comments made to look more intelligent and other shoppers appreciate the easier to read clean copy. The added revenue is merely a side note. Sort of.

“A well-written review tends to inspire confidence about the product, even if the review is negative. Typically, such reviews are perceived as objective and thorough. If we have a high-quality negative review, this may serve as a guarantee that the negative aspects of the product are not that bad after all,” wrote Panagiotis Ipeirotis, an associate professor at NYU’s Stern School of Business. “For example, a negative review, such as ‘horrible battery life. In my tests, battery lasts barely longer than 24 hours,’ may be perceived as positive by other customers who consider a 24-hour battery life to be more than sufficient.”

The academic posted the next logical step, based on some university research projects. “We noticed that demand for a hotel increases if the reviews on TripAdvisor and Travelocity are well-written, without spelling errors. This holds no matter if the review is positive or negative. We observed similar trends for products sold and reviewed on Amazon.com.”

Regarding the Zappos example, Ipeirotis tried to make a standard P&L analysis. “Given that Zappos spent at least 10 cents per review, and that they examined approximately 5 million reviews, this is an expense of a few hundred thousand dollars. My archive on MTurk-Tracker kind of confirms these numbers. So, the expected revenue improvement should have been at least a few million dollars for this exercise to make sense. Ethical? Notice that they are not fixing the polarity or the content of the reviews. They just change the language to be correct and error-free. I can see the counter-argument that the writing style allows us to judge if the review is serious or not. So, artificially improving the writing style may be considered as interference with the perceived objectivity of the user-generated reviews. I still consider it fine to change the grammar, from the ethics point of view.”

The dangerous part is setting limits.

Why Did Gonzales Hackers Like European Cards So Much Better?

I am still unclear about the core point here-- why higher value of European cards. Supply and demand, yes, makes sense. But the fact that the cards were chip and pin (EMV) should make them less valuable because that demonstrably reduces the ability to use them fraudulently. Did the author mean that the chip and pin cards could be used in a country where EMV is not implemented--the US--and this mis-match make it easier to us them since the issuing banks may not have as robust anti-fraud controls as non-EMV banks because they assumed EMV would do the fraud prevention for them Read more...
Two possible reasons that I can think of and have seen in the past - 1) Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code. 2) Also, in offline chip countries the card determines whether or not a transaction is approved, not the issuer. In my experience, European issuers haven't developed the same checks on authorization requests as US issuers. So, these cards might be more valuable because they are more likely to get approved.

A smart card slot in terminals doesn't mean there is a reader or that the reader is activated. Then, activated reader or not, the U.S. processors don't have apps certified or ready to load into those terminals to accept and process smart card transactions just yet. Don't get your card(t) before the terminal (horse). Read more...
The marketplace does speak. More fraud capacity translates to higher value for the stolen data. Because nearly 100% of all US transactions are authorized online in real time, we have less fraud regardless of whether the card is Magstripe only or chip and PIn. Hence, $10 prices for US cards vs $25 for the European counterparts. Read more...
@David True. The European cards have both an EMV chip AND a mag stripe. Europeans may generally use the chip for their transactions, but the insecure stripe remains vulnerable to skimming, whether it be from a false front on an ATM or a dishonest waiter with a handheld skimmer. If their stripe is skimmed, the track data can still be cloned and used fraudulently in the United States. If European banks only detect fraud from 9-5 GMT, that might explain why American criminals prefer them over American bank issued cards, who have fraud detection in place 24x7. Read more...
