Cross-country wording notes

The same calculation is phrased differently by country and language. Locale pages exist to match those variations more directly.

  • Productivity-style tools usually attract both short keyword queries and descriptive searches.

  • Locale pages perform better when the surrounding copy matches practical local phrasing, not only the formula name.
