Amazon: unfair tactics are employed by third-party vendors who want to increase sales of new products on the site
Items without reviews or with few reviews appear further down in the surveys and sell less
Festive shoppers are being warned to watch for misleading product reviews on the site - after a Channel 4 investigation found that some five-star ratings were related to totally different items.
The findings, revealed in the documentary The Truth About Amazon, reveal that popular products such as headphone adapters have had their average ratings boosted by a series of unrelated ratings for items such as remotely controlled helicopters, a cat scratch post and even an inflatable birthing ball.
