WordPress Headless avec Frontend Next.js

No. The wp-admin experience is identical — same dashboard, same editor, same plugin interfaces. The only visible change is that clicking Preview routes through the Next.js frontend via Draft Mode instead of loading a PHP theme. Most editors don't even notice, other than the previews loading faster.

Backend plugins like ACF, Yoast, Gravity Forms, and WooCommerce keep working normally. Plugins that inject HTML via PHP hooks — visual page builders, for example — need to be replaced with React components. We audit every plugin during discovery and flag anything that needs migration before we touch a line of code.

Both Yoast and Rank Math expose all SEO metadata through the REST API and WPGraphQL. We pull titles, meta descriptions, Open Graph tags, canonical URLs, and schema markup into Next.js generateMetadata. The output matches what you had before — usually better — and you get dramatically faster page loads on top of it, which helps rankings directly.

We target 95+ across Performance, Accessibility, Best Practices, and SEO on both mobile and desktop. Monolithic WordPress typically scores 40–55 on mobile. Static generation, ISR, edge caching, and optimized image delivery consistently push those numbers above 95 in production.

Nothing visitors would notice. Next.js serves pre-rendered pages from the edge cache, so the frontend stays fully operational even during a WordPress outage. Editors won't be able to publish new content until the backend recovers, but visitors see zero downtime. That's a real resilience advantage over monolithic WordPress.

A typical site — under 200 pages, standard custom post types, ACF fields — takes 5–6 weeks from kickoff to production. Larger projects with WooCommerce, multi-language support, or complex custom plugin logic can run 8–10 weeks. We scope everything precisely during discovery so nothing surprises you mid-project.
