FitTractor.com earns commission on some outbound product links, including links to Amazon as a participant in the Amazon Associates programme. This page states which links pay the site, how they are marked, and why the arrangement cannot influence a compatibility verdict. Every paid link is labelled in the page text and carries the sponsored and nofollow attributes, so a reader can tell a monetised link from a manufacturer source link before clicking. Compatibility verdicts are produced by comparing published specifications; no step of that comparison reads whether a product is monetised, and a record that carries a paid link is held to a stricter sourcing standard than one that does not, requiring a confirmed manufacturer document. Commission is paid by the retailer and does not change the price a reader pays.
