wp-admin RetainedLighthouse 95+ISR & Server Components

Headless WordPress with Next.js Frontend

Q: Will my editors need to learn a new CMS?

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.

Q: Do my existing WordPress plugins still work?

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.

Q: How does headless WordPress handle SEO without a PHP theme?

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.

Q: What Lighthouse score can I realistically expect?

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.

Q: What happens to my site if the WordPress server goes down?

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.

Q: How long does a headless WordPress migration take?

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.

Keep wp-admin. Replace everything visitors see.

Your WordPress backend doesn't change. Your frontend becomes a Next.js application that hits 95+ on Lighthouse. Editors keep their workflow. Performance stops being a problem.

What Is Headless WordPress?

Headless WordPress keeps wp-admin and your plugin ecosystem intact while swapping out the PHP theme layer for a Next.js frontend. Content comes through via REST API or WPGraphQL. The frontend uses Incremental Static Regeneration to serve pre-rendered pages — the kind of speed a monolithic WordPress setup simply can't match.

Your Current Site May Be a Liability

Common gaps we find in nearly every audit.

Lighthouse mobile scores stuck between 40 and 55, even after you've thrown every caching plugin at it

Risk: Google penalizes slow pages in search rankings, and every 100ms delay eats into your conversions.

PHP themes are a single point of failure

Risk: One bad plugin update can take everything down at once — editors and visitors lose access together.

Editors like wp-admin

Risk: Developers hate writing PHP templates. And hiring decent frontend talent gets harder and more expensive every year.

WordPress exposes your entire application stack to the public internet

Risk: Brute-force attacks on wp-login, XML-RPC exploits, plugin vulnerabilities — they're all live attack surfaces, right now.

Page builders and shortcodes lock your content inside rendering engines that fight performance

Risk: That content also becomes non-portable — you can't pipe it to a mobile app or any other channel without a fight.

Server-rendered PHP can't keep up with static or ISR delivery at the edge

Risk: Traffic spikes strain your server, push up hosting costs, and degrade the experience for everyone hitting your site at the same time.

What Your Website Could Look Like

How We Build This Right

Every safeguard, built in from Day 1.

WPGraphQL Integration

We wire up WPGraphQL to expose posts, pages, custom post types, ACF fields, and Yoast metadata as efficient GraphQL queries. No over-fetching, no wasted bandwidth.

Incremental Static Regeneration

Pages get statically generated at build time and revalidated in the background on a configurable interval. Visitors always hit a cached edge response while the content stays current behind the scenes.

Draft Preview for Editors

Next.js Draft Mode intercepts preview clicks from wp-admin and renders unpublished content through the production frontend. Editors see exactly what visitors will see — no surprises, no "it looked different in preview."

SEO Metadata Pipeline

Yoast and Rank Math data flows through the API into Next.js generateMetadata. Titles, descriptions, Open Graph tags, canonical URLs, JSON-LD structured data — all handled automatically.

Attack Surface Reduction

Your WordPress instance sits behind a firewall with no public theme rendering. Only the API endpoint is exposed, which cuts out most of the common WordPress exploit vectors.

On-Publish Revalidation

A lightweight webhook fires the moment an editor hits Publish. That triggers on-demand ISR, so updated content goes live in seconds — no full rebuild required.

What We Build

Purpose-built features for your industry.

React Server Components

Data fetching runs server-side with zero client-side JavaScript overhead, which trims bundle size and improves Time to Interactive.

Edge Caching via Vercel

Static and ISR pages are served from 100+ edge locations globally. Your site stays fast even if the WordPress server goes down entirely.

ACF Pro Field Mapping

Custom fields, flexible content layouts, and repeater data get mapped to typed TypeScript interfaces for reliable, predictable rendering.

Image Optimization Pipeline

Images from the WordPress media library run through the Next.js Image component with automatic WebP/AVIF conversion, lazy loading, and responsive srcsets.

Sitemap & RSS Generation

Dynamic XML sitemaps and RSS feeds are generated at build time from your WordPress content graph and submitted automatically to Google Search Console.

Multi-language Support

WPML or Polylang data is exposed via the API and routed through Next.js i18n, keeping hreflang tags and locale-specific metadata intact for every language.

Our Development Process

From discovery to launch. Quality at every step.

WordPress Audit & API Setup

Week 1

We start with an audit of your existing WordPress instance — plugins, custom post types, ACF fields, SEO configuration. We install WPGraphQL, expose all content types, and lock down the public-facing PHP layer.

Next.js Frontend Build

Weeks 2–3

Then we scaffold the Next.js app with App Router, map every WordPress template to a React component, and configure ISR with tuned revalidation intervals. Draft Mode preview gets wired up for your editors at this stage.

SEO & Performance Tuning

Week 4

Yoast and Rank Math metadata gets piped into generateMetadata. We optimize images, implement structured data, configure sitemap generation, and keep iterating until every Lighthouse category is clearing 95.

Editor Training & QA

Week 5

Your content team then tests the full editorial workflow end to end — draft, preview, publish, revalidate. We work through every edge case: custom fields, scheduled posts, revision history, multi-author workflows.

Deploy & Monitor

Week 6

Finally, we deploy to Vercel with production caching, configure on-publish webhooks, set up uptime monitoring for both the WordPress API and the Next.js frontend, and stay on for 30 days of post-launch support.
