How we rank

Meta-rankings combine expert endorsements.

ReviewFinder's formal aggregated ranking is a combination of our meta-rankings and consumer score.

Meta-rankings are a combination of all expert reviews we can find on the Internet. When present, meta-rankings are the strongest ranking signal (we trust experts more than consumers).

ReviewFinder - how we rank via Consumer Score

Consumer score is calculated from customer reviews.

Not all categories have enough expert endorsements online - in such cases we use consumer score weighted by historical brand prominence in the niche (brands that historically specialize in a certain category get a slight bump in that category rankings). Consumer score is a normalized 0-10 score based on customer reviews.

Recently we removed price form our rankings - it no longer affects recommendations. Whether to go budget or premium is consumer's choice, not ours.
