A detailed explanation of Amazon Review Weight! (Bonus at the end of the article)

First of all, I would like to make it clear that Amazon has never announced the content of Review weight to the public. Our understanding of Review weight is entirely based on imagination.
 
In order to better understand the content of Review Weight, I changed my way of thinking to understand it, that is, how to identify fake reviews. From this perspective, I found a website that aims to help consumers restore the real ratings of products. In general, this website and Amazon are doing the same thing, which is to find out fake reviews and delete their impact. Based on the data of the website, we can try to introduce the way competitors get reviews, or let us avoid being caught for fake orders.
 
The weight of the rating is composed of each reviewer. It will be very inspiring for us to integrate the characteristics of each Reviewer. Understanding the weight of each account will help us understand the weight of the rating in LISTING.

One-Hit Wonders One-time Reviewer:
These accounts wrote one review, which means they only reviewed one product. Unbiased reviewers are often long-time members of a site and they generally do not review just one product. If a product has too many one-time reviewers, it can indicate that there is a suspicion of review manipulation. While there are many reasons that may lead to one-time reviewers on a product, a few common reasons include: fake accounts, or somehow inducing people who don't write reviews to leave a review.
 
Take-Back Reviewers Users whose reviews have been deleted:
Include reviewers who have deleted reviews in their history. These reviewers are suspicious because the review was most likely removed by Amazon due to a Terms of Service violation. The reviewer was caught manipulating reviews before, and it’s unclear if they have stopped violating the rules.
There are some other reasons for deleting comments:
1. The buyer wants to delete it.
2. The brand contacts the buyer to remove the review - usually a negative one.
3. Amazon may delete a review - usually a positive one - if it believes it violates its rules.
4. After the review was posted, the platform changed its rules and deleted it. For example, after Amazon updated its review policy, many existing misleading reviews were deleted. Another example is that Amazon lowered the upper limit of Vine reviews for each product, so many Vine reviews that exceeded that limit were deleted.
 
Single-Day Reviewers
Buyers who posted all their reviews in one day are marked as one-day review buyers. These buyers' accounts are questionable because they do not leave reviews like most people, and it is not ruled out that they leave reviews on a whim.
 
Substantial repeated phrases
If there are a high number of reviews that use repeated phrases, it may indicate that the review was not created organically. However, there are still many good reasons why some phrases are repeated, and these phrases do not necessarily indicate that the review is biased. For example, in the case of electronics, many buyers will mention the features of the product, and it is normal for these words to be repeated. However, if several buyers write the same marketing language or subjective words exactly word for word, it may indicate that these buyers are ghostwriters.
 
Overrepresented participation
1. Sellers use gifts or other means to get buyers to review their products. This will cause buyers who usually do not write reviews to not write reviews for the products, resulting in too many buyers with few review records.
2. Sellers look for service providers to brush, which will lead to abnormal structure of buyers.
 
The above are the factors that influence the review weight, and there are some explanations.

What affects the weight is not only the buyer's account, but also the structure of the comments under LISTING, including sentences, review date, etc.
