From WordPress to Headless: A Migration That Tripled Our Client Speed
A 4.8s load time was killing conversions. Here is the exact migration playbook that took a WordPress site to sub-1s performance.
The problem with slow
Google research is brutal: 53% of mobile users abandon sites that take over 3 seconds. Our client was at 4.8s on WordPress with 40+ plugins.
The migration playbook
- Freeze content in a structured audit (pages, sections, media).
- Rebuild in Next.js with a drag-and-drop admin so non-devs keep control.
- Redirect map — every old URL preserved, zero SEO loss.
- Ship in sprints — homepage first, then landing pages, then blog.
The results
- Load time: 4.8s → 0.9s
- Lighthouse: 98/100
- Conversions: +178%
If your WordPress site feels slow, it is costing you money every single day.
