Measured health tools, not app-store gloss.
Programmatic SEO starter
Build one health calculator site that can grow from 1 page to 100.
This starter turns your strategy into a working editorial-style front end: a home page, category hubs, 30 calculator routes, a reusable template, and internal links that feel intentional instead of random.
Category covers behave like magazine spreads.
Detail pages keep imagery subtle so the calculator stays in control.
Three-layer structure
The architecture matches the strategy you pasted.
- Home page introduces the cluster and priority pages.
- Category hubs act as searchable landing pages, not empty lists.
- Calculator detail pages share one scalable SEO template.
Featured live pages
Start with the pages most likely to become your pillar assets.
TDEE, calorie deficit, macro, BMI, body fat, protein, heart-rate zones, and running pace are already interactive in the starter.
