Additionally, a consistent pattern of reviews being posted at regular intervals can also indicate suspicious activity. By analyzing the review frequency, Booking.com can identify potential fake reviews and take appropriate action.

Review Length

The length of a review is one of the factors that Booking.com considers when detecting fake reviews. Genuine reviews tend to have a reasonable length, providing enough details about the experience. On the other hand, fake reviews may be overly short or excessively long, lacking specific information or containing irrelevant details.

Reviewer Reputation

Booking.com takes into account the reputation of reviewers when detecting fake reviews. Reviewers with a history of providing genuine and helpful feedback are given more weight in the review validation process. This helps to ensure that the reviews are coming from trustworthy sources and increases the accuracy of detecting fake reviews.

Positive reviews may use similar phrases and expressions, while negative reviews may highlight common issues. Additionally, comparing the length of reviews can provide insights into the level of detail provided by different reviewers. By analyzing these factors, Booking.com can identify potential review networks and detect review manipulation.

Identifying Review Networks

Identifying review networks is crucial in detecting fake reviews. By comparing reviews and analyzing patterns, booking.com can identify groups of reviews that are likely to be manipulated. This helps in validating genuine reviews and ensuring the authenticity of the feedback provided.

  1. As a hospitality specialist, I find two of bellow very concerning:
    1) When the managment is asking employees, friends and family to post review to increase the rating (they use this method in seasonal destinations where they are waiting for summer to pass so they lower the price of accommodation and amount of comission for booking.com is lower);
    2) When they contact the person who left bad review and offering compensation if they change their rating – Basically blackmail the guest.
    Booking.com should not allow 90 dates to change the rating once it is pósted. They should allow the guest to write comment within 90 days, but once it is out only 24h to change. If someone change the rating just because they are given money, it is not genuine rating and misslrading potencial future guest who are going to book.
