Headless WordPress: a complete SEO playbook

Headless WordPress means your content stays in WordPress while a separate front end — usually Next.js — renders it. Done right, you get the editing experience your team loves and the performance Google rewards. Done wrong, you ship a client-rendered site Google struggles to index.

Render on the server, always

The single biggest mistake is shipping a client-only front end. If the HTML arrives empty and JavaScript fills it in, you're gambling with crawlability.

ts
// Fetch at request/build time and return real HTML
export default async function Page({ params }) {
  const post = await getPost(params.slug);
  return <Article post={post} />;
}

Map every redirect before launch

Your URL structure will change. Export the old map, build the new one, and ship 301s for every changed path on day one.

A migration without a redirect map is just a controlled traffic loss.

Planning a migration?

We run headless migrations end to end — rendering, redirects, metadata and Search Console — so rankings hold.
