How to detect fake customer reviews and avoid them?

Consumers’ ability to detect fake customer reviews greatly depends on their ability to avoid the pitfalls of misinformation and make informed decisions when purchasing online.

It is therefore essential for any buyer of an online product or service to know the techniques and strategies through which to distinguish fake customer reviews from real ones. To this end, this article briefly presents some approaches to detect fake customers and prevent them from influencing you.

Analyze reviews carefully

To detect fake customer reviews on a product, sometimes you just need to pay special attention to suspicious reviews.

Language level

Unless they have been posted on a trusted platform like Custplace whose reviews are NF ISO certified, which means that Transparency in the process of collecting, moderating, and publishing reviews is guaranteed, customer reviews found online may be false. The language level is one of the very first indicators for detecting fake customer reviews. Indeed, a review that contains many grammatical or spelling errors deserves your suspicion since it is highly likely to be false. Additionally, an authentic customer review is usually written in a natural tone. If you have the impression when reading a review that it is unnatural, it may also be a fake review.

Length of reviews

Customer review length is another key metric for detecting fake online customer reviews. Typically, fraudulent reviews are brief and lack specific details or explanations of the user experience. On the other hand, authentic reviews are generally longer, more detailed, and express nuanced opinions. A real customer who takes the time to leave a review generally shares their experience with the product or service. Comments that are too short, especially when there are many of them, can therefore be a sign of an attempt at manipulation.


It is also possible to detect fake customer reviews by examining their content. Indeed, fraudulent reviews tend to use excessively laudatory or negative language, devoid of realistic nuances. Authentic reviews, on the contrary, express balanced opinions. Thus, having opinions in which there is a repeated use of superlatives, an overly positive tone or extreme criticism can indicate that it is a question of fake review. By carefully evaluating the tone and content of reviews, you can distinguish sincere reviews from intentional manipulation.

The date of publication of the notices

When a large number of reviews are posted on the same day or within a short period, this may indicate an attempt at manipulation. Fake reviews are sometimes posted in mass to quickly damage the reputation of a product. In addition, a concentration of opinions on a specific period, without previous or subsequent activity, can raise doubts. Paying some attention to the publication date of reviews you suspect can help you discern genuine reviews from fraudulent reviews.

Study author activity to detect fake reviews

The detection of false reviews can also be carried out by taking an analytical look at the profile and activity of their authors. Here too, intensive activity over a short period may imply that this is a fictitious customer.

In addition, the profiles of fake authors are generally less extensive than those of genuine customers. You will only find:

  • Very little or no personal details;
  • No profile photo;
  • No purchase history.

This may suggest that these are accounts created quickly for the sole purpose of posting biased reviews. Examining the diversity of products or services a user reviews can also be informative. If an author gives opinions on very disparate areas, and in a short period, this raises questions about the credibility of these comments.

Finally, if the reviews posted by an author are very similar to each other or duplicate from one product or service to another, then it is undoubtedly a fictitious customer who publishes fake reviews. This article tells you more, in addition to indicating how to know if a site is reliable.
