Moving from WordPress to Next.js

A practical, honest look at migrating from WordPress to Next.js: when it pays off, what it costs, how long it takes, and the traps that wreck timelines and SEO.

WordPress runs a huge chunk of the web, and for good reason: it is cheap to start, easy to staff, and a non-technical person can publish a post without calling anyone. So before we talk about leaving it, let's be honest. Most sites do not need to leave. The ones that do usually share a few specific symptoms, and if you do not have those symptoms, a migration is an expensive way to feel modern.

When the move is actually worth it

A WordPress to Next.js migration makes sense when you keep running into the same walls. Here are the ones that come up over and over.

Your site is slow and you have already tried the usual fixes. You bought better hosting, installed a caching plugin, ran a CDN, and your Largest Contentful Paint is still ugly on mobile. At some point the bottleneck is the stack itself: PHP rendering on every request, a stack of plugins each adding queries, and a theme that loads more than it needs.

You have an app, not a blog. The moment your "website" grows a dashboard, a booking flow, gated content, or anything that talks to your own database and APIs, WordPress starts fighting you. You end up writing custom PHP, wrestling with plugin conflicts, and praying nothing updates badly on a Tuesday.

Plugin sprawl has become a security and maintenance tax. Twenty active plugins means twenty things that can break, get abandoned, or get exploited. Every WordPress site we inherit has at least one plugin nobody remembers installing.

Your developers refuse to work in it. If your team is React and TypeScript people, asking them to maintain a WordPress theme is slow and miserable, and miserable people write worse code.

If none of those apply, stay put. A well-tuned WordPress site with a good host and a light theme is perfectly fine, and we will tell you that for free.

What you actually gain

Next.js gives you control over how and when each page is built. Static pages can be pre-rendered and served from a CDN, so a blog post or landing page loads almost instantly because no server has to think when a visitor arrives. Pages that need fresh data can render on the server per request. You choose per page instead of accepting one global behavior.

Performance is the headline most founders care about, and it is real, but the bigger long-term win is that the code is just code. State lives in a Git repo, deploys are predictable, you can preview every change before it goes live, and you can hire from the large pool of React developers instead of the smaller pool of people who enjoy WordPress internals.

You also get a cleaner split between content and presentation, which leads to the question everyone forgets to ask early.

The part people underestimate: the CMS

Here is the trap. Founders picture the new fast site but forget that their marketing team still needs to publish posts without filing a ticket. Next.js is not a CMS. You have to pair it with one, and that choice shapes the whole project.

The common paths:

  • Headless WordPress. Keep WordPress purely as the editing backend and pull content into Next.js through its API. Your editors keep the admin they know, and you get a fast front end. It is the lowest-friction option when the content team is attached to WordPress.
  • A dedicated headless CMS like Sanity, Contentful, or Payload. Cleaner and more modern, better structured content, but your team has to learn a new editor and you migrate all existing content into it.
  • Git-based / MDX, where posts are files in the repo. Great for developer-heavy teams and docs, wrong for a marketing team that wants a friendly editor.

There is no universally correct answer. The right pick depends on who publishes content and how often. Decide this before anyone writes a line of front-end code, because redoing it midway is a common cause of a blown budget.

SEO: where migrations go to die

This is the section that should scare you a little, because a careless migration can tank traffic you spent years earning.

The non-negotiables:

  1. Keep your URLs identical where you can. If you cannot, 301 redirect every old URL to its new home. Every single one. Export your full URL list first, because the day after launch is the wrong time to discover you forgot a few hundred.
  2. Match your metadata. Titles, meta descriptions, canonical tags, Open Graph data, and structured data all need to carry over. Next.js handles this well through its metadata API, but it does not happen by accident.
  3. Keep your sitemap and robots rules consistent, and resubmit the sitemap after launch.
  4. Watch Core Web Vitals. This is usually where the new site wins outright, and that win is worth protecting.

Keep Google Search Console open for weeks after launch, watching for crawl errors and ranking dips. A small wobble for a week or two is normal. A cliff means a redirect or a tag got missed, and you fix it fast.

Rough timelines and cost

These are ranges, not quotes, and they move a lot based on content volume and how much custom functionality you have. Treat them as ballpark.

  • A small marketing site or blog (say 10 to 40 pages, light custom work): roughly 3 to 6 weeks.
  • A mid-size content site with a real CMS migration, a few hundred posts, and custom layouts: roughly 6 to 12 weeks.
  • A content site plus app functionality (auth, dashboards, integrations): several months, and at that point it is a product build, not a migration.

Cost tracks the same shape. A clean small-site migration tends to land in the low thousands to low five figures. Anything with serious content migration and custom features moves well past that. The single biggest cost driver is rarely the front end. It is the content migration and the CMS decision, exactly the part people skip past in the first call.

One ongoing note: Next.js hosting is not free like a cheap WordPress plan can be. Budget for a host such as Vercel or a Node setup. It is usually modest, but it surprises people.

What to watch out for

A few things that quietly wreck projects:

  • Forms, comments, and search. WordPress gives these to you through plugins. In Next.js you build or integrate them. Inventory every interactive feature on your current site before you scope, because "oh, and the contact form" has eaten many timelines.
  • The redirect map. Said it already, saying it again. It is the most common skipped step and the most expensive to fix after launch.
  • Editor training. If the CMS changes, your content team needs an afternoon of hand-holding. Budget for it.
  • Scope creep disguised as a redesign. Migrating and redesigning at once doubles the surface area and the risk. If you can, migrate first on the existing design, then redesign. Mixing them makes it impossible to tell whether a traffic dip came from the new tech or the new layout.

The takeaway

Moving from WordPress to Next.js is a strong call when you are fighting performance, outgrowing the platform, or building something closer to an app. It is the wrong call if you mostly want to feel current. If you go ahead, spend your early energy on two things most teams underestimate: choosing the right CMS for the people who publish, and building a complete redirect and metadata plan so your SEO survives the jump. Get those right and the rest is mostly careful engineering.

If you want a second opinion on whether your site is a good candidate, we are happy to take a look and tell you honestly either way.
