Editorial standards
Every calculator page should place the calculator early, explain the result in plain language and disclose the method used. Support articles must help users understand a calculator topic; they are not created only to target keywords.
Review workflow
Before a page is marked complete, the research log must identify sources reviewed, formulas confirmed, competitor weaknesses, edge cases and QA checks. Health, finance, tax, legal and pregnancy topics require extra caution and visible limitations.
Corrections
If a formula, source, data point or explanation is found to be wrong or unclear, the page should be corrected and the relevant documentation updated.
