The 10 specs that move the technical score the most. Impact = share within its area × the area's weight.
How review counts and ratings become the user score.
Review counts are mapped through a logarithmic decay function rather than raw averages. In Robot Vacuums, reaching the top 8% threshold (6,100 reviews) awards full statistical significance points. Beyond this cap, diminishing returns prevent mass-market products with 30,000+ unverified reviews from crowding out superior low-volume models.
We pool the ratings of the same product from listings in up to 7 countries (UK, DE, FR, IT, ES, NL, US). Each listing counts by its number of reviews, so a rating drop in one country moves the score only as much as its share of the reviews.
Record of test methodology updates and algorithm revisions.
Every ranking on Frontum is strictly algorithmic. We never accept paid product placements, sponsored rankings, or free manufacturer review units.
