Migrating from WordPress to Next.js is not just a frontend rebuild. It is an SEO migration, content migration, analytics migration, and launch operation wrapped into one project.
The technical stack can improve speed and control, but the launch can still hurt search visibility if redirects, metadata, canonicals, internal links, tracking, or indexing controls are missed.
Use this checklist before, during, and after the migration.
If you want help turning this into an actual launch plan, start with a WordPress migration audit.
Export or crawl:
Do not rely only on the WordPress admin. Crawl the public site because the live site may include generated archive pages, media URLs, plugin routes, landing pages, or old redirects that the admin does not make obvious.
Keeping URLs the same is usually the least risky path when the existing URL structure is clean.
Change URLs only when:
For every changed URL, map old to new.
| Old URL | New URL | Status |
|---|---|---|
/old-service-page/ | /services/new-service/ | 301 |
/blog/old-post/ | /blog/updated-post/ | 301 |
/thin-duplicate-page/ | Best matching parent page | 301 or retire |
Google's migration guidance is clear that URL changes should be handled carefully to reduce search impact. Redirects are one of the core controls.
Migrate:
Do not blindly copy everything. Some old metadata is keyword-stuffed, duplicated, outdated, or generated by plugins in a way that no longer fits the new page.
Use this rule:
Internal links often break during WordPress rebuilds because old editors used absolute URLs, page-builder blocks, plugin shortcodes, or outdated category links.
Check:
Internal links help search engines discover pages and understand relationships. They also help users move from informational content into the service page, which is why every migration cluster should link back to the main WordPress to Next.js migration page.
WordPress SEO plugins often handle more than people realize.
Before launch, identify what plugin-generated behavior must be recreated:
In Next.js, these features usually move into code, CMS fields, or deployment configuration. That is good for control, but only if someone maps them before the old plugin disappears.
Next.js can statically render pages, dynamically render pages, cache data, and revalidate content depending on how the route is built.
For SEO pages, confirm:
Google recommends good Core Web Vitals for search success and user experience, but good performance scores do not guarantee rankings. Treat performance as one part of the migration, not a magic SEO lever.
SEO traffic does not matter if lead capture breaks.
Check:
Do this before launch and again after launch. Form failures are common because the frontend changes while hidden backend destinations stay assumed.
Before DNS or production switch:
After launch:
Some ranking fluctuation can happen during URL or infrastructure changes. The goal is not to promise zero movement. The goal is to avoid preventable mistakes and respond quickly.
If you cannot check everything in one pass, start here:
That protects the pages most likely to affect leads and revenue.
