Verified with Google PageSpeed Insights. Re-run any of these yourself at pagespeed.web.dev — we publish the URLs and dates.

Your rankings are an asset you refuse to gamble

Organic traffic drives your pipeline. Before we write a line of code, we build the full URL inventory, the 301 redirect map, and metadata and schema parity. Search equity survives because it is protected by process — not by hope.

Your WordPress site is now the bottleneck

Failed Core Web Vitals, plugin sprawl, a theme nobody wants to touch. You have already tried fixing. What you need now is the migration done once, properly, by people who have shipped it before.

You want the senior engineer, not the account manager

The partner who scopes your migration is the engineer who builds it. Named owner, written scope, milestones you can hold us to, and a staging environment you review before anything goes live.

You expect the numbers before the pitch

Our pricing ranges, our timelines, and our performance results are published on this page — before you ever get on a call. Nothing here requires you to take our word for it.

Proof, not promises

Delivered work you can inspect before you call

We build on both sides of this migration. Our WordPress work — like the custom booking platform for Travellers Autobarn — is why we can move your content out safely, and why we will tell you honestly if migration is not the right call yet.

  1. Discovery & migration audit

    URL inventory from Search Console, plugin and integration map, content model documentation, and a written scope with line items. If an agency quotes your migration without this, they are guessing.

  2. Redirect map & SEO baseline

    Every indexable URL mapped to its destination before development starts. Canonicals, metadata, and structured data catalogued so nothing is lost in the rebuild.

  3. Next.js build with editorial preview

    Component-level rebuild on Next.js — static generation or ISR by default, WPGraphQL or REST as scoped, and Draft Mode so your editors preview content before publishing.

  4. Zero-drama cutover

    Staging review, redirect QA, schema verification, and a launch checklist. DNS flips only when everything passes — parallel hosting keeps the old site as a safety net.

  5. 30–90 day SEO monitoring

    Search Console watch on indexation, rankings, and crawl errors after launch. A migration is finished when your organic traffic is stable — not when the code deploys.

Search & AI visibility

Ranked by Google. Cited by AI. Both, by design.

Buyers now find agencies through AI assistants as often as search results. Every migration ships with technical SEO and GEO (Generative Engine Optimization) — and we practice both on this very site.

Technical SEO — protecting what you have

  • 301 redirect map covering every indexed URL
  • Metadata, canonical, and sitemap parity in Next.js
  • Structured data rebuilt server-side: Organization, Service, FAQ, BlogPosting
  • Search Console monitoring for 30–90 days post-launch

GEO — making AI recommend you

  • llms.txt profile so AI assistants describe your business accurately
  • Entity JSON-LD and consistent citations across your profiles
  • Answer-first FAQ structure that AI systems quote directly
  • Crawl policy for GPTBot, ClaudeBot, PerplexityBot, and Google-Extended

Transparent pricing

The ranges we publish before you ever call

Real ranges from delivered projects. Final scope is confirmed in writing after discovery — minimum engagement $10,000.

Will migrating from WordPress to Next.js hurt my SEO?

Not when it is handled properly. We build the 301 redirect map before development starts, preserve metadata and structured data, and monitor Search Console for 30–90 days after launch. Rankings typically stabilise within weeks on a well-run migration.

How much does a WordPress to Next.js migration cost?

Most business migrations land between $10,000 and $50,000. Small sites (up to 20 pages) run $10k–$18k, medium sites (20–100 pages) $18k–$38k, and large or WooCommerce-heavy builds $38k–$75k+. Every engagement is scoped in writing before work begins.

How long does the migration take?

Small sites take 6–10 weeks, medium sites 10–16 weeks, and large or complex platforms 4–6+ months. Content migration and redirect QA usually take longer than the React build itself.

Do my editors have to leave WordPress?

No. With headless WordPress your team keeps the admin they know — WordPress stays the CMS, Next.js serves the public site. If WordPress itself is the problem, we can migrate content to Sanity or Contentful instead. We recommend the path that fits your workflow during discovery.

What is GEO, and is it included?

GEO (Generative Engine Optimization) makes your site discoverable and citable by AI assistants — llms.txt profiles, entity JSON-LD, FAQ structure, and AI crawler policy. It is included in every migration alongside technical SEO, and we practice it on this very site.

Do you work with US companies?

Yes. We deliver remotely for US and international brands, with overlap on US working hours, a named owner on every engagement, and scope defined in writing. Our published case studies and PageSpeed results are verifiable before you commit.

What proof do you have that your builds are fast?

Our own site scores 99 Performance and 100 SEO on PageSpeed Insights.
