v0 and Next.js to WordPress: a technical migration review

Understanding what v0 actually generates

v0 produces React components, usually styled with Tailwind CSS and built on the Next.js App Router. That means the pages you see are the result of server components, client components and a build step that bundles JavaScript and CSS. WordPress works differently: it renders PHP templates on the server and stores content in a database. A successful migration therefore does not copy source code one to one. It captures the rendered result and rebuilds it as WordPress pages and a theme.

From a systems perspective this is a good thing. The rendered HTML is the most stable representation of your site. It contains the final text, the final structure and the final class names, independent of the framework version or the packages that produced it.

Rendering: from React output to WordPress markup

The cleanest approach is to read each public page as a browser would, after rendering, and translate the DOM into WordPress content. Headings stay headings, paragraphs stay paragraphs, images become media library items and buttons become button blocks or plain links. Layout containers become groups, columns or custom HTML where needed.

Interactive client components, such as tabs, carousels or accordions, are converted into their closest WordPress equivalent. In practice most of them map well to core blocks or a lightweight block plugin. Very custom interactions may be simplified, which is normal and easy to refine later.

Tailwind CSS in a WordPress theme

Tailwind generates utility classes at build time and only ships the classes you actually use. When a site is converted, that final compiled stylesheet is what matters. It can be loaded by the WordPress theme so the existing class names keep working, which preserves spacing, colours and typography without rewriting the design.

For long-term maintenance it is wise to map the main colours and fonts into the theme settings as well. Editors then see the same palette inside the block editor, and new pages automatically match the converted ones.

Routing, slugs and permalinks

Next.js routes are folders and files; WordPress routes are permalinks. Set the permalink structure to 'Post name' and give every page the same slug it had before. Nested routes such as /services/design become child pages with the same hierarchy. Dynamic routes, for example a blog at /blog/[slug], become posts with matching slugs.

Any URL that cannot keep its exact address should receive a permanent 301 redirect. A redirect plugin makes this a matter of minutes and protects the ranking signals your pages have already earned.

What is not converted: server logic and data

API routes, server actions, database calls and authentication are application logic, not page content. No page converter can turn them into WordPress automatically. Forms are rebuilt with a form plugin, logins with a membership plugin and shops with WooCommerce. This split is actually healthy: WordPress handles content, while proven plugins handle the dynamic parts with regular security updates.

SEO checks after the move

Install an SEO plugin, copy every meta title and description, verify that each page has a self-referencing canonical, and submit the new XML sitemap in Search Console. Compare the old and new HTML of a few key pages to confirm headings and internal structure are intact. Small visual differences after conversion are normal and are usually fixed in the block editor or with a plugin.
