A slow WordPress site, an Elementor build nobody can safely edit, a mobile PageSpeed score in the 40s. Here is the 2026 path to a fast site without sinking six months into it.
Rebuild only if the platform is the problem
Rebuild for 4-second loads, plugin conflicts and un-editable layouts. Don't rebuild to change colours — that is a redesign and you can do it on the current stack.
What it costs in 2026
| Scope | Cost | Timeline |
|---|---|---|
| Simple site (brochure, blog) | from ~USD 2,000 | 2–6 weeks |
| Content site with custom layouts | USD 10,000–25,000 | 6–12 weeks |
| WooCommerce / complex | USD 10,000–50,000+ | 6 weeks–6 months |
| DIY (your time) | hosting only, USD 0–240/yr | weeks of evenings |
WordPress → Next.js / headless, 2026.
The biggest cost driver is template count. A 50-page site with 22 unique Elementor layouts is 22 React components to build and test — audit your layouts before you price anything.
The step order
- Inventory every URL, layout, form and integration.
- Pick the stack — Astro for mostly-content sites, Next.js for app-like interactivity. Keep WordPress headless if the team writes in it happily.
- Rebuild layouts as components, one per unique template.
- Migrate content; images to a CDN.
- Map 301 redirects for every old URL — this is where SEO is won or lost.
- Cut over, switch DNS, keep the old site on a subdomain for a week.
- Monitor Search Console, Core Web Vitals and 404s for a month.
Keep your SEO through the move
- 301-redirect every old URL, including trailing-slash and case variants.
- Keep titles, meta and canonical tags identical unless deliberately improving them.
- Regenerate and submit the sitemap on cutover day.
- Expect a 1–3 week ranking wobble; a clean migration recovers within weeks.
This is the pillar version. The full 7-step framework, the rebuild-your-business method and the case study of this site are on the Rebuild website / business hub.
