Editorial standard
Product ranking methodology
Every ranking is built from defined category criteria, source-backed claims, and human editorial review before publication.
How Rankings Work
Each category defines the factors that matter most to shoppers, such as performance, cleaning, durability, usability, and value. Products are scored against those weighted criteria with item-level rationale, pros, cons, best-for guidance, and not-for guidance.
Source Standards
Sources may include manufacturer pages, manuals, official specifications, standards bodies, reputable editorial reviews, and documented hands-on testing. RankReason does not use scraped Amazon prices, star ratings, review counts, customer reviews, Prime badges, coupons, availability claims, or Amazon-hosted images.
Publication Checks
The build rejects missing source links, invalid score weights, missing reviewer metadata, missing affiliate disclosures, unsafe Amazon content, and broken Luxembourg store-choice link data. That keeps ranking pages consistent before they are deployed.
