WordPress to Next.js Migration
Escape slow load times and plugin chaos. Move your WordPress site to Next.js and watch Lighthouse go from 45 to 100.
Why leave WordPress?
- Average Lighthouse score of 45–65 on mobile
- PHP renders on every request — no CDN caching
- Plugin bloat adds 200-500KB of render-blocking scripts
- Security vulnerabilities in 91% of sites come from plugins
- Hosting costs scale with traffic spikes
- Page builders (Elementor, Divi) produce bloated HTML
What you gain
- Lighthouse 95–100 on every page
- TTFB under 50ms from CDN edge nodes globally
- Zero plugin dependencies — no more update anxiety
- Static HTML served from CDN — unhackable frontend
- Hosting costs drop 60-80% on Vercel free tier
- TypeScript codebase that is maintainable and extensible
The WordPress performance ceiling
The average WordPress site scores 45–65 on Lighthouse mobile. With a page builder it is often lower. This is not a hosting problem or a caching problem — it is an architectural problem. WordPress renders PHP on every request, loads jQuery, your theme''s CSS bundle, and a dozen plugin scripts before the user sees anything.
Next.js solves this at the architecture level. Marketing pages are pre-rendered to static HTML at build time and served from a CDN. There is no PHP, no database query, no plugin execution. TTFB drops to under 50ms. LCP drops from 3-4 seconds to under 1 second.
What gets migrated
All of it: posts, pages, categories, tags, custom post types, featured images, author data, and comments if you want them. I use the WordPress REST API and WP-CLI to export everything cleanly. No content is lost. Redirects are set up for every URL that changes.
SEO preservation
This is where most migrations go wrong. I map every existing URL to its new equivalent, implement 301 redirects, preserve canonical tags, copy over your Yoast or RankMath SEO metadata, and submit the new sitemap to Search Console. Rankings typically hold within 2-4 weeks and often improve within 60 days due to better Core Web Vitals.

| LCP | 3.8s avg | Under 1s |
| TTFB | 400–800ms | Under 50ms |
| Monthly hosting | $30–$100 | $0–$20 |
| Plugin vulnerabilities | High | Zero |
| Build complexity | Low initially | Moderate (worth it) |
Common questions
How long does a WordPress to Next.js migration take?
A standard brochure site (10-30 pages) takes 3-4 weeks. A blog with 100-500 posts takes 4-6 weeks. A WooCommerce store adds 2-4 weeks for the commerce functionality. I give a fixed timeline before we start.
Will I lose my SEO rankings?
Not if the migration is done correctly. I implement 301 redirects for every changed URL, preserve all meta titles and descriptions, and submit updated sitemaps. Rankings typically hold within 2-4 weeks and often improve within 60-90 days as better Core Web Vitals are recognised.
What happens to my WordPress plugins?
Plugin functionality is rebuilt natively in Next.js or replaced with purpose-built services. Contact forms become API endpoints. SEO metadata comes from your CMS. Analytics are reintegrated. You end up with fewer dependencies and faster load times.
Can I still use WordPress to manage content?
Yes — headless WordPress keeps WordPress as your CMS and replaces only the frontend with Next.js. Editors continue working in wp-admin. Alternatively, I migrate content to Sanity or Supabase for a cleaner setup.
What CMS will I use after migration?
Three options: headless WordPress (editors keep wp-admin), Sanity (best developer + editor experience), or Supabase (for programmatic content). I recommend based on your team''s workflow and content volume.
