Amazon sellers boost listings with reviews from different products


The consumer watchdog found that 9 out of 10 of the top-rated headphones on the online market carried glowing evaluations for unrelated products and solutions, ranging from cuddly toys to jigsaw puzzles and umbrellas.

Which? thinks that these listings have been misleadingly boosted making use of a loophole identified as review merging abuse. It implies that Amazon is struggling to avoid third-celebration sellers from manipulating its assessment technique to raise their products and solutions, which hazards undermining shopper have confidence in. The Level of competition & Marketplaces Authority claims £23 billion of shopper spending is influenced by on the web assessments.  

Which? looked at Bluetooth headphones – a well-liked group on Amazon’s British isles web site – and arranged the success by ‘average shopper reviews’, to mimic how a buyer may possibly shop if they are wanting for the greatest-rated headphones on the website. Bose was the only recognized manufacturer throughout the top rated 10 headphones which did not exhibit any signals of evaluation abuse. 

The other nine had been not known or tiny-recognised makes, which did not show up to be offered on any other web sites aside from Amazon. Which? identified they had been artificially boosted by 1000’s of irrelevant reviews for completely distinct items – like umbrellas, personalised jigsaw puzzles, bowls, glass jars, extension prospects, cuddly toys and a keyboard desk tidy. In some cases, the listings had no testimonials for Bluetooth headphones at all.

Two of the nine artificially boosted listings Which? located experienced gained the coveted Amazon’s Selection badge, even with currently being inflated by clearly illegitimate testimonials.

Merging evaluations can be a genuine way for sellers to handle their catalogue when they have a shut variation of an current item to increase to a listing – this sort of as the exact same product or service offered in a distinctive colour. But performing this for unrelated items is against Amazon’s phrases and conditions. It is misleading, and would make a solution show up a lot more preferred than it is – and much more desirable to buyers seeking to make a swift buy. 

While sellers can merge their personal product or service evaluations, some unscrupulous sellers uncover approaches to merge opinions from other people’s listings much too, which is identified as ‘hijacking.’ On Amazon’s possess discussion board for sellers, there are much more than 50 threads mentioning “review hijacking” as the subject matter, the place individuals complain of having their merchandise opinions “co-opted” and “stolen” by other sellers.

The most remarkably rated headphones, boasting five stars out of five, were ‘Amazon’s Choice’ and had acquired 40 reviews – but none of the reviews have been about headphones. All of the testimonials, such as a few testimonials evidently showing images of the merchandise, were being for “plushie” toys.

The next pair of headphones to be labelled Amazon’s Option have been totally propped up by reviews for an extension direct quite a few consumers claimed could be a fire hazard. Which? observed no mentions of headphones or earbuds in any of the 207 assessments, even though all nine image testimonials showed an extension cable. Most of the reviews for the products were being five stars, and helpful to the score of the headphones, but various reviewers claimed the extension guide was unsafe.

One particular listing experienced 863 evaluations for a personalised jigsaw puzzle – with just three opinions for the headphones by themselves. An additional had 1,386 assessments that appeared to be for seaside umbrellas – together with 64 image reviews. Which? did not obtain a person overview for this listing that stated earbuds or headphones. 

Which? targeted its investigation on just a person preferred product category, but has also witnessed the issue throughout other types, including smartphone chargers with critiques for surge protectors, tweezers boosted by critiques for non-adhere kitchen area foil, and blackhead getting rid of nose strips boosted by opinions for wigs.

Suggests an Amazon spokesperson:

“Amazon groups client testimonials for product versions like colour and dimension, and we have very clear guardrails in place to avoid products and solutions from being improperly grouped, both thanks to human error or abuse. Our proactive actions detect and block the vast majority of abuse in our shop quickly however, we are disappointed when terrible actors evade our techniques, and we will continue on to innovate and invest in our applications and procedures.

“If we discover element pages with incorrectly grouped assessments, we use these learnings to boost our prevention mechanisms. We have now taken proper enforcement motion versus the product or service listings and sellers in issue.”

Nevertheless, Which? thinks Amazon desires to improved enforce its personal guidelines, specifically specified it first raised issues about evaluate merging back in 2019.

Suggests Rocio Concha, Which? Director of Plan and Advocacy:

“Unscrupulous businesses are exploiting weaknesses with Amazon’s assessment method, leaving purchasers at risk of buying solutions boosted by thousands of bogus 5-star assessments.  

“Once again, this reinforces the worth of the CMA’s ongoing faux reviews investigation receiving to the base of the situation and ensuring that key procuring internet sites are shielding persons from these unfair procedures.

“The federal government also declared its intention to deal with faux evaluations as portion of its customer and competitors reforms and should deliver forward new legal guidelines, in the forthcoming Queen’s Speech, to banish these exploitative procedures as before long as probable.”
