Affiliate links
If a link is eligible to earn a commission, we disclose that relationship close to the recommendation or comparison. The price you pay should not increase because of our commission.
Fitment grades
Fitment grades are determined by evidence strength. Commission rate, sponsorship, free products and advertising spend cannot raise a grade.
Sponsored visibility
Paid placements must be labeled. A sponsor may buy clearly marked visibility, but cannot buy an editorial conclusion or remove a documented fitment conflict.
Product access
If a merchant provides a sample, discount or installation access, the relationship is disclosed in the relevant content. We document both positive and negative findings.
Corrections
Merchants and owners can challenge a record by providing evidence. Material corrections are reviewed without requiring a commercial relationship.
