Commercial pages state facts users need before purchase: country, currency, use region, values, restrictions, redemption and delivery. Guides begin with a short answer, use explicit headings and link to relevant products without hiding material limits.
Facts are reviewed against official brand or provider material and carry a review date. Corrections are logged promptly; poorly documented pages stay visible but use noindex,follow until verification. Translation must preserve meaning instead of reverting important text to English.
Product restrictions are written from a source hierarchy: issuer terms and help centers first, then public authorities or payment-provider documentation, with secondary material used only for discovery. Each substantive claim should store its direct URL, supported point and access or revision date. Language versions carry the same meaning; translation may clarify syntax but must not add availability, guarantees, prices or legal conclusions absent from the source.
A review is triggered by a scheduled freshness check, a broken source, a brand-policy change, customer evidence or a correction request. Conflicts are resolved in favor of the most specific current official source and uncertainty is labeled. Material corrections should record what changed and when. Commercial placement must not rewrite factual conclusions; sponsorship or affiliate relationships, if introduced, require visible disclosure. No fictional author, expert credential or publication age is assigned.
