The total ranking of a product in a category, represented by the bar length, is based on a weighted aggregate score. The score is calculated using the following factors:
- Comparisons Views: the product with the highest number of comparisons with other products-in-the-category gets a maximum of 25 points. Every other product gets assigned points based on its total in proportion to the #1 product in that ranking factor. For example, if a product has 80% of the number of comparison views compared to the product with the most reviews then the product's points for reviews would be 25 * 80%.
- Views: We calculate the number of Views based on the percentage of category comparisons out of the total comparisons of the product.
- For example, if a product has 100 Comparisons with other products in the category and a total of 1,000 Comparisons, the product will be assigned 10% of the total number of Views. If the product has a total of 2,000 Views, it will be assigned 200 Views for this ranking factor.
- The product with the highest number of views gets a maximum of 25 points. Every other product gets assigned points based on its total in proportion to the #1 product in that ranking factor.
- For example, if a product has 100 Comparisons with other products in the category and a total of 1,000 Comparisons, the product will be assigned 10% of the total number of Views. If the product has a total of 2,000 Views, it will be assigned 200 Views for this ranking factor.
- Reviews: the product with the highest number of reviews gets a maximum of 15 points. Every other product gets assigned points based on its total in proportion to the #1 product in that ranking factor. For example, if a product has 80% of the number of reviews compared to the product with the most reviews then the product's points for reviews would be 15 * 80%.
- Rating: the maximum score is 25 points awarded linearly between 6-10
- e.g. 6 or below=0 points; 7.5=7.5 points; 9.0=18 points; 10=25 points.
- Words/Review: the maximum score is 10 points awarded linearly between 0-900 words
- e.g. 600 words = 4 points; 750 words = 7 points; 900 or more words = 10 points.
- If a product has fewer than ten reviews, the point contribution for Rating and Words/Review is reduced: 1/3 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.
All products with 50+ points are designated as a Leader in their category.
