77% of online shoppers use user reviews and ratings while making purchases online. This means that companies increasingly rely on positive online user reviews to make money.
Enter, astroturfing.
“Astroturfing” is a play on the idea of a grassroots movement. In this case, instead of people supporting a business from the grassroots through genuine online reviews and recommendations to friends, businesses are paying to have these positive reviews written for them, giving them the false appearance of having a grassroots fan base. As people increasingly turn to online user reviews to help them make decisions about everything from what to buy to where to vacation, companies have come to rely more and more on positive reviews for their business. This pressure has caused many companies to engage in astroturfing in order to keep up with the competition.
A recent exposé in the New York Times by David Streightfeld shows how astroturfing is being used on major websites like Amazon, Yelp!, and TripAdvisor. Streightfeld cites Craigslist posts in which users solicit positive reviews with posts like “I will pay for positive feedback on TripAdvisor,” and “If you have an active Yelp account and would like to make very easy money please respond.” Streightfeld also interviewed freelance writers some of whom are making up to $10 per review writing reviews on sites like Amazon.
We even run into this problem with fake user reviews on Pikimal from time to time. For instance, take a look at this glowing review of one of the vodkas in our Vodkas Piki.

This vodka sounds pretty amazing, right? That is until you find out that this particular review was posted on the same day that we were contacted by a PR firm representing that brand of vodka and the review was posted using the same email address as the one the PR firm used to contact us. That sort of transparent astroturfing may seem brazen – or even downright sloppy – but this is hardly an isolated incident. Fishy user reviews like this one appear on our site all the time. Some are easy to catch, some are a little more tricky, and undoubtedly some manage to escape detection.
The problem that we, and so many other websites face, is what to do about astroturfing. Some companies use human review to try to get rid of fake reviews. Unfortunately, this system can only realistically eliminate the most obvious offenders, and on sites like Amazon with millions of of user reviews, having a person review each one is impractical. Computer algorithms are sometimes used to do some of the sorting work, but even these are not absolute answers.
For consumers, a better answer might be to refer only to reviews and recommendations from friends and people you know. The website Stamped.com is a great example of a way to do this. Stamped allows users to share their favorite books, restaurants, music, movies and more directly with the people in their social networks. By dealing only with the recommendations of people you know, you can at least be somewhat more certain that the recommendations you are getting are genuine. Unfortunately, you don’t always agree with your friends, and if you are trying to make a decision about something that none of them have tried before, you are left flying blind.
So what other options do consumers have?
I started Pikimal to help address some of the issues that cause people to turn to user reviews to make decisions in the first place. As we’ve seen in Part 1 and Part 2 of this discussion on user reviews, the system of user ratings utilized by most major websites is extremely flawed – maybe even irreparably so. But why do people turn to user reviews in the first place?
I think for most of us, user reviews are a way of having more confidence in our purchases. Especially when we are buying something with which we may not have much experience, looking to the experiences and knowledge of others seems like a much better option than making a decision based on marketing or random choice. The problem is that by relying on user reviews, consumers can get the feeling that they are making better decisions without having actually made a better decision at all.
But what else can people do? For someone to actually make a truly good decision they would need to be able to have all of the relevant information and would need to be able to process it in a way that made certain that they were making the best choice for their unique needs and circumstances. No one has the time or the capacity to become an expert on every product that they purchase, so user reviews seem like the best alternative.
The really cool thing about Pikimal, however, is that we’ve built a tool – the Piki – that takes all the facts about a set of products and uses an individually customizable algorithm to allow consumers to find the right products for them. There’s no need to be an expert on something to know that you are making the best decision. You just tell the Piki what is important to you, and using the facts available for each product, the Piki tells you which is the best for you. Users can include reviews and ratings in their decision if they like, or if they’d rather just go with the facts, they have the option of eliminating them altogether.
Pretty cool, huh? We think so.
