Next.js for business websites: why we build on it
Easy Insight Team ·
We build on Next.js because it renders real HTML on the server, keeps a marketing site and a product in one codebase, and treats SEO metadata as a first-class concern rather than a plugin. It is not the right answer for every site — a simple brochure site is usually better off elsewhere.
Most agency pages leave that last sentence out, so here is where the line sits.
What is Next.js, in one paragraph?
Next.js is a React framework for building websites and web applications. React on its own runs in the browser: the server sends a near-empty page and JavaScript assembles the content once it arrives. Next.js renders pages to HTML on the server or at build time, sends that finished HTML to the browser, and only then hands over to JavaScript for the interactive parts. It is open source, maintained by Vercel, and on version 16 as of September 2026.
For a business site, that one difference is most of the story.
Why does server rendering matter for a business website?
Because of what a search crawler does with your page. Google processes JavaScript in three stages — crawling, rendering, then indexing — and rendering is not immediate. Google's own documentation says pages are queued for rendering, and that a page may sit in that queue for "longer than" a few seconds (Google Search Central, JavaScript SEO basics). If your content only exists after JavaScript runs, you are betting your indexing on that queue. If it is in the first HTML response, you are not.
The same logic increasingly applies to answer engines: the crawlers behind AI search products execute little or no JavaScript. Server-rendered HTML is the lowest-risk way to be readable by all of them at once.
Next.js goes further than plain server rendering. In version 16, the default model is Partial Prerendering: the static parts of a page are built once and served straight from a CDN, while anything genuinely per-request streams in behind a placeholder (Next.js documentation). One personalised element no longer forces the whole page to be slow.
Is Next.js better than WordPress?
Not universally, and we would rather say so plainly. WordPress is used by 40.7% of all websites as of September 2026, a content management system market share of 58.9% (W3Techs). That is not simply inertia; for a certain shape of site it is the right tool.
Here is roughly how we decide:
| Your situation | Our usual recommendation |
|---|---|
| Five to fifteen pages, marketing content, edited by non-technical staff, no custom logic | WordPress or a hosted site builder |
| Content-heavy site where publishing speed beats everything else | WordPress with a serious hosting setup |
| Site that must do something — calculators, gated content, portals, quoting tools | Next.js |
| Marketing site plus a product that should share design, code and deployment | Next.js |
| Deep integration with a CRM, ERP or internal database | Next.js |
The framework question is downstream of a better one: is this a website, or a web app with a website attached? We wrote a separate piece on telling those two apart, because getting it wrong is the most expensive mistake in this category.
What does Next.js actually give you that matters commercially?
Four things, in our experience of building and running them.
Metadata is part of the framework, not an add-on. Next.js has a Metadata API for titles, descriptions and Open Graph tags, plus file conventions that generate sitemap.xml and robots.txt from code (Next.js documentation). This site uses all of them: when a new article is added, the sitemap, navigation, feed and social preview image regenerate themselves at build time. Nobody has to remember, which means nobody forgets.
Speed is the default, not a project. Static pages are served from a CDN as finished HTML, and images, fonts and scripts are optimised by the framework, not by a plugin somebody has to keep configured. Be careful how much you claim for that, though: Google says Core Web Vitals are used by its ranking systems, but also that "there is no single signal", and warns that chasing a perfect score purely for SEO reasons may not be the best use of your time (Google Search Central, page experience). Fast is table stakes, not a ranking strategy.
One codebase for the site and the thing the site does. A pricing calculator, a client login, a booking flow — in a plugin-based stack these become a second system bolted onto the first, with its own hosting, design and bills. In Next.js they are more routes in the same project. Our web app work almost always starts here.
You own it. The code is standard React and TypeScript, and it deploys to any modern host. No proprietary page builder holds your layout hostage.
When would we talk you out of it?
When the site is a leaflet. Eight pages that rarely change, no integrations, no logic — a Next.js build is a more expensive route to the same result, and it adds a dependency on developers you would not otherwise have.
The other honest downsides:
- No plugin marketplace. Features get built, not installed — better for quality, worse for budget on commodity functionality.
- It moves quickly. The framework has changed substantially across recent major versions, so budget for maintenance rather than treating a build as a one-off purchase.
- Content editing needs a plan. Next.js is a front end, not a CMS. Pair it with a headless CMS and agree the editing boundary up front, or you will have built a site your marketing team has to raise a ticket to change.
None of those are reasons to avoid the framework. They are reasons to choose it deliberately.
Frequently asked questions
Is Next.js good for SEO?
Yes, provided it is built properly. Next.js renders pages to HTML on the server or at build time, so a crawler gets your content in the first response rather than waiting on JavaScript. It also has first-class conventions for the metadata search engines read — a Metadata API for titles and descriptions, and file conventions for sitemap.xml and robots.txt. None of that writes your content for you. Framework choice removes technical obstacles; it does not create relevance.
Is Next.js better than WordPress for a business website?
Not universally. WordPress is the pragmatic choice for a brochure site that non-technical staff edit daily and that needs no custom logic — it runs 40.7% of all websites as of September 2026 for good reasons. Next.js earns its keep when the site has to do something: gated content, calculators, portal logins, integrations with your CRM or ERP, or a marketing site and a product that should share one codebase.
Does a Next.js website need a developer to update content?
It should not. Next.js is a front end, not a content system, so it is normally paired with a headless CMS your team edits in a browser. Content changes then go live without a developer. What does need a developer is changing how the site works — new page types, new logic, new integrations. Agree that boundary before the build starts.
How much does a Next.js website cost in the UK?
It depends far more on scope than on framework. The cost sits in how many page templates, integrations and pieces of custom logic you need, not in the choice between Next.js and something else. Our guide to what a custom web app actually costs in 2026 breaks the ranges down.
What are the downsides of Next.js?
It needs developers. There is no plugin marketplace to bolt a feature on in an afternoon, the framework moves quickly enough that an untouched codebase feels dated within a couple of years, and it is genuine overkill for a five-page brochure site nobody plans to extend. If your site is a leaflet, buy a leaflet.

Thinking about a site or a web app?
One scoping call with the developer who would build it, then a fixed written estimate before any work starts. Websites from £3,500, custom web apps from £8,000, on the same stack as the page you're reading.
