The brief
The goal was long-tail Google traffic for thousands of specific queries like “concrete for a 10x12 slab, 4 inches” — each one answered by a fast, dedicated page with the math already done.
What we built
- Programmatic pages for common sizes and materials from a single template.
- Interactive calculators as Astro islands, with all copy and results in static HTML.
- Glossary and cheat sheets for informational queries, with internal linking across sections.
- Static Astro build served from a CDN for instant loads.
