This migration case study explains the move from WordPress to Next.js for a service business that needed better performance and reliability without losing search visibility.
Migration context
The business relied on a WordPress site for service pages, blog content, and lead capture. The site had slow page loads, a heavy plugin stack, and frequent hosting issues.
The goal was:
- preserve organic traffic
- improve Core Web Vitals
- reduce backend maintenance
Pre-migration planning
1. Audit the existing site
- export top-performing pages
- map URLs and query intent
- identify plugin-dependent features
2. Create the redirect plan
- keep stable URLs when possible
- map old URLs to new equivalents
- prepare 301 redirects for moved pages
3. Validate staging content
- deploy the Next.js site on a staging host
- verify page output and metadata
- run the same analytics and Search Console checks as production
Implementation highlights
Preserve content and metadata
The migration kept the page titles, headings, and core copy intact for the highest-value pages.
It also preserved structured data and canonical tags to keep search engines aligned.
Use parallel validation
Before cutover, the team compared page renderings across the WordPress site and the Next.js site.
Any content or layout mismatch was fixed before the production redirect went live.
Cutover and monitoring
The migration used a staged cutover plan:
- deploy the new site on a temporary host
- activate redirects for the first set of pages
- monitor Search Console URL indexing and organic traffic
- complete the remaining redirects when validation is clean
The team also kept a rollback snapshot of the old site for 24 hours.
Results
- search impressions held steady
- page speed scores improved dramatically
- the new site launched with no major SEO issues
Post-launch, the service pages had better user experience and improved mobile performance.
What made it successful
- a strong preflight audit
- a conservative URL strategy
- active monitoring after cutover
- clear communication between SEO, dev, and the client
Practical advice for similar migrations
- keep the site structure familiar for users and search engines
- migrate content in phases if the site is large
- always have a rollback or freeze window
- monitor organic traffic closely for at least one week
