Editorial Policy

One page per distinct task

Calculator pages are published only when the user task, inputs or interpretation is materially distinct. Reverse conversion keywords that can be solved by one strong converter are consolidated rather than expanded into doorway-style pages.

Regulated calculations

Tax and tariff claims prioritize primary official sources. A material regulatory change receives a new ruleset version, verification date and changelog entry. Calculation review and editorial review are tracked separately.

AI, AEO and GEO

We do not create special pages solely to target AI systems or query variations. Pages are structured for clear answers, visible evidence and crawlable information so the same useful resource can serve people, conventional Search and generative search experiences.
