In October of 2016, Amazon reacted to accusations of posting biased reviews by making a significant change to their review policy. The goal was to eliminate reviews that were incentivized in some manner, particularly those provided in exchange for receiving a free or discounted item. And this included book reviews. The way that Amazon implemented this change was to summarily remove any review that contained a disclaimer indicating possible bias, and then to ban the reviewer. If this approach seems reasonable to you, then think again. Allow me to illustrate that the new policy not only doesn’t work, but has actually made things worse.
Consider two buyers—Alpha and Beta. Both receive a free item (which might simply be an ebook) in exchange for agreeing to post a review. Note that they have not promised to write a favorable review. Alpha is honest, and includes a disclaimer with the posted review. Beta simply posts a review without revealing the possible bias. In the past, Amazon would have left both reviews up. Now, they key on disclaimers, so Alpha’s review would be removed, while Beta’s less honest review remains. In other words, Amazon’s reviews are now, on average, less trustworthy, because dishonesty is rewarded while honesty results in punishment. The incentivized reviews are still there, but they are now impossible to recognize.
I ended up being caught out by this. I had just self-published my first book and had asked friends and family to post reviews. Because I am an honest person, I suggested that they might include a disclaimer that they knew the author. The ones that did had their reviews summarily deleted by Amazon.
So learn from my mistake. Tell your reviewers to be dishonest, because that allows Amazon to feel better about itself. 🙂
