Amazon Fake Customer ReviewsA lot of people look at customer reviews online before they make a purchase. After all, they're like vicarious test-drives: You get the benefit of previous users' experiences in deciding whether a product or service is worth the money or delivers what it advertises.

The pre-purchase advice is great -- if you can trust the source. But often, you can't. In fact, many customer reviews are just another form of marketing controlled by the businesses you're trying to evaluate.

One Out of Three Online Consumer Endorsements Are Fakes

The problem is pervasive: A recent New York Times story highlighted a business called GettingBookReviews.com, which posts positive "consumer reviews" on websites such as Amazon.com (AMZN) -- for a fee. These fake customer reviews say exactly what a book's writer would want them to -- that the book was amazing, of course. Soon after starting his business in 2010, owner Todd Rutherford was raking in the orders and making about $28,000 per month.

That's just one example of marketers muddying the customer-review waters to market products. According to data-mining expert Bing Liu, approximately one-third of online consumer reviews are written by marketers or retailers, not real consumers.

Don't believe it? Consider this: Amazon customers are rating new books higher than renowned classics. How can this be? One self-published writer, Roland Hughes, suggests it's because "[r]eviews for the established classics tend to come from actual readers." Although it could be argued that more people are reading contemporary books than classics.

Ferreting out Phonies

Fake customer reviews aren't unique to Amazon. A few years back a PR agency got into trouble for allegedly breaking the Federal Trade Commission's truth-in-advertising laws by paying employees to post favorable reviews of their customers' games on iTunes without disclosing that doing so was part of their job.

Other companies are trying to crack down on outsiders' attempts to abuse the customer recommendation system. For example, Facebook (FB) recently announced that it was cracking down on "likes" that were "gained by malware, compromised accounts, deceived users, or purchased bulk Likes." TripAdvisor (TRIP) has also warned customers that some of its online reviews may be fraudulent, and is exploring methods for detecting and eliminating fake reviews.

In addition to warning customers, these companies are enlisting the help of data-mining experts to help them create algorithms that can aid them in the discovery and elimination of bogus reviews. These algorithms assist consumers by looking for clues most of us are too busy to find on our own, such as semantic inconsistencies between posts from the same user name, or how frequently a user evaluates products.

Spotting False Praise

Product reviews can have a strong impact on our purchasing decisions because humans have a natural tendency to look to others for signals about how to behave. If someone else praises an item or service, we're more likely to think it's worth our time and money.

Fortunately, there are ways to spot those fakers, and defend ourselves from their influence.

One study, conducted at Cornell University, found that fake reviews focused more on narratives and relied a great deal on superlatives rather than providing concrete descriptions -- probably because fake reviewers rarely have actual experience with the products or services they evaluate. Suspect reviews also used the words "I" and "me" more frequently, perhaps to reinforce their credibility as "real" people.

These study results suggest we should look for reviews that offer concrete descriptions about the product or service to determine whether it fits what we're looking for rather than simply relying on the communication of vague positive or negative impressions.

Buying products online in 2014 should not be such a mystery to everyone. I buy a lot (like package on my doorstep every day a lot) and have never looked at a review. The way to online shop without the risk is to purchase from reputable places. If you buy on Amazon, purchase only Amazone Prime eligible items that are "shipped and sold by Amazon". Amazon has a great return policy and you know where it is coming from. If you purchase directly from a company, make sure you can find information about the parent company somewhere. If you can't, it may be a scam but if it is a publicly traded company for years, you know they have something to loose if they rip you off.

I don't know what's more amazing in the comment section, the people who have delusions of grandeur and warn others about "scams" that are directed at their favorite product/self-written "novel" or whatever, or the people who have such vitriol that they can't even manage to comment on the article, but instead have to rail about the government/blame the lack of Christ-centered lives/worry about the lies perpetuated by the media.

People, it's time to either grow up or seek mental help. Whichever it is, get off the internet and leave commentary to those who can respond intelligently.

As for this article, it's pure logic to not just blindly trust reviews of strangers. Do the real research, use trustworthy organizations, such as Consumer Reports, get off the couch and go to a real store and actually examine products. There are plenty of ways to find out what's in your best interest without relying on the "kindness" of strangers.

Unfortunately, Caveat Emptor or Buyer Beware, is more true than ever. I check reviews but it's impossible with products that are just being marketed or if no one has written a review. Before I buy I also call the company to see where the product is made. The Kyrobak is $300, which is a lot of money. For that much money it should be made in the United States. If it's made in China, it's being made by workers who make between $8.00 and $12.00 a week and not only loath the Americans for whom the goods are being sold but their Communist supervisors, whom they try to continuously outwit. The worst products are sold on those awful commercials that beg the consumer to buy one and get one free, just pay for shipping. The buyer can be assured that crap is made in China from inferior materials, low-paid workers, and greedy corporations.

There are some good plugins that sites can use - like Yotpo - that prove it's a real customer who's posting the review because there's a 'verified customer' icon next to their name.

I disagree with the commentary directing readers to pay more attention to negative reviews. Public Relations companies know that every mom and pop seller can fake their own reviews or buy good reviews now, so they went on the offensive. Bad reviews are now as fake as good reviews. The industry provides negative campaigning against the competition. A good example is the publishing industry attempting to hold back the flood of self published books going toe-to-toe with the big name publishing houses for consumer dollars. Negative down voting and cut and paste negative attacks effectively steer buyers away from indie books with nasty labels made by crowds of "top reviewers" who are paid hourly wages and receive freebie incentives. Interns work there way up in the publishing world by attacking the competition online. Of course they all deny they're doing this since it is illegal and immoral to deceive consumers with false advertising, either positive or negative.

That is hysterical! I'm sure Stephen King and John Grisham are just a'quakin' in their boots over the fear of a poorly-edited self-indulgent "novelist" who has so little confidence in his or her own work they can't bring themselves to search for an investor who will believe in their "skills" as much as they do.

Of course they all deny it. It isn't happening. I'm sure your self-published tripe is just bad.

Get real.

The same thing goes for restaurant an hotel reviews, folks. It's called MARKETING. Pay more attention to the negative reviews - those you can be sure are from real customers.

If a book isn't worth reading on the toilet it isn't worth buying.

I review a lot of things on Amazon, not just books or DVDs. I am honest when giving my opinions but, I agree, not everyone is. In fact, I read a review last week that someone posted about a book that I had reviewed over six months ago and it was very obvious to me that the reviewer had not only not read the book but had plagiarized part of my review word-for-word! Why would anyone want to do that?

in the beginning, reviews were mostly real. corporate America soon realized the lying potential. we live in a rural setting. shopping is minimal. we stick with the sites that have provided us with what they advertised. a friend of ours has a business. he was approached, actually has been approached many times, by people wanting a fee to falsely rate his business. he has turned them down, but my point is that there is no integrity, much less ant type of truth in advertising laws on the books. wouldn't matter, no one could enforce them. let the buyer beware.
