IT Central Station computes a RankingScore for each product based on a composite of:
- Number of reviews
- Average star rating
- Number of times the product has been compared with alternative solutions
- Number of views of reviews
- Number of followers on IT Central Station
The total ranking of a product, is based on a weighted aggregate score. The score is calculated as follows: The product with the highest count in each area gets the highest available score. (20 points for
Reviews; 16 points for
Views,
Comparisons, and
Followers.) Every other product gets assigned points based on its total in proportion to the #1 product in that area. For example, if a product has 80% of the number of reviews compared to the product with the most reviews then the product's score for reviews would be 20% (weighting factor) * 80% = 16. For
Average Rating, the maximum score is 32 points awarded linearly based on our rating scale of 1-10. If a product has fewer than ten reviews, the point contribution for Average Rating is reduced (one-third reduction in points for products with 5-9 reviews; two-thirds reduction for products with fewer than five reviews). Reviews that are more than 24 months old, as well as those written by resellers, are completely excluded from the ranking algorithm.
