Niche Calculator Tool Site
A blueprint for building a small static website around genuinely useful calculators and checklists for a narrow audience.
Who this helps
Builders who want an AdSense-friendly utility site instead of a thin article farm.
Problem
Many niche content sites are too generic. Useful calculators and checklists can create original value and stronger trust signals.
