Next.js sites built to be server-rendered, fast and found.
Next.js is only as good for search as the way it is built. We build it the way search engines and AI assistants need it read: server-rendered on first request, light on the client, and structured to rank from the day it launches.
Next.js website design is the practice of building a site on the Next.js framework so that its pages are server-rendered into real HTML, load fast, and are structured for search engines and AI assistants to read, rank and cite. Rogue Logic builds bespoke Next.js sites on the App Router, using server components, static generation and incremental regeneration to ship crawlable HTML and strong Core Web Vitals, rather than a client-rendered single-page app that hides content from crawlers. Bespoke builds start at £5,000 plus VAT, with hosting and management on our own platform from £100 a month.
Next.js websites, in full.
Next.js is the framework most modern marketing sites should be built on, and also the one most often built in a way that undoes its own advantages. Used well, it renders your pages to HTML on the server, ships a light client bundle and gives search engines and AI assistants exactly what they need on the first request. Used badly, it becomes a client-rendered single-page app wearing a React logo: fast to demo, slow on real phones, and half-invisible to a crawler that never runs the JavaScript. The framework is not the win. The way it is built is.
The failure modes are specific and common. A site that opts every route into client-side rendering, so the HTML a crawler first receives is nearly empty and the content only appears after hydration. A hydration cost so heavy that the page is visually there but not interactive, dragging Interaction to Next Paint into the red. Metadata and canonicals handled inconsistently across the App and Pages routers, so duplicate and conflicting signals leak into the index. Images and fonts shipped without the framework's own primitives, undoing the performance the framework was chosen for. None of these announce themselves. They show up as a beautiful site that will not rank, or a rebuild that lost traffic the old site used to earn.
We build Next.js the other way round. Rendering is decided per route: static generation for pages that rarely change, incremental static regeneration for content that updates on a cadence, server rendering for the genuinely dynamic, so each page arrives as real HTML and stays fast. React Server Components keep data-fetching and heavy logic on the server and the client bundle small. The Metadata API, canonicals and JSON-LD are built into the layout so every page is described correctly and consistently. When a headless CMS is in play, we wire it so editors get a clean workflow without bloating what ships to the browser.
This is senior work by design. Choosing a rendering strategy per route, keeping the server and client boundary clean, planning a migration off an older stack without losing rankings, or deciding where structured data earns its place is judgement, not a checklist a junior runs on autopilot. The four of us have spent roughly forty years between us building and ranking sites, which is why we take on the builds other agencies called complicated.
Next.js websites, broken down.
App Router, server components and the rendering model
The App Router and React Server Components are where Next.js earns its keep, keeping data-fetching and heavy dependencies on the server and shipping less JavaScript to the browser. We build with a clean server and client boundary so pages render to HTML first and stay light, instead of dragging the whole tree into the client.
Static, ISR and server rendering per route
Static generation, incremental static regeneration and on-request server rendering each suit different content. We pick per route against how the page changes and how it must be found, so marketing pages are pre-rendered and instant while dynamic pages stay fresh, rather than one blanket mode compromising both.
JavaScript SEO and the render gap
A Next.js site can still hide its content behind client-side rendering if it is built carelessly. We check what a crawler receives against what a user sees and close the gap, so your pages are readable on the first request.
Explore →Core Web Vitals and the client bundle
Speed comes from using the framework properly: next/image for responsive, lazy imagery, next/font to kill layout shift, route-level code splitting and streaming to cut time to first byte and hydration cost. We fix performance at the source so it holds under a real catalogue of pages.
Explore →Metadata, canonicals and structured data
The Metadata API and JSON-LD are built into the layout so titles, canonicals, Open Graph and schema are correct and consistent across every route. Entities and canonicals resolved cleanly are what let search engines and assistants read and cite you.
Explore →Headless CMS and content workflow
Next.js pairs naturally with a headless CMS, but only if the integration is clean. We connect the two so editors get a sensible workflow and preview, without shipping the CMS's weight to the browser or breaking the render strategy.
Explore →The way we run Next.js websites.
Scope the build and the search
We start from how you need to be found and how the content behaves: the commercial pages, the terms and AI surfaces, and which content is static, which updates on a cadence and which is genuinely dynamic. The rendering strategy is designed around that, not chosen by default.
Design around the buyer, not a template
A bespoke design built for your buyers and the actions you need them to take, so the site converts rather than just resembling every other React starter.
Build clean, server-first and fast
Hand-built on the App Router with server components, per-route rendering, next/image and next/font, semantic HTML and schema in the layout, so pages arrive as real HTML and pass Core Web Vitals from the first line, not as a retrofit.
Wire content and data cleanly
Where a headless CMS or data source is involved, we integrate it so editors have a clean workflow and preview while the client bundle stays light and the render strategy holds.
Migrate and launch without losing rankings
If you are moving off an older stack, we launch behind a full redirect map, handled in next.config or middleware, and verify against live crawl and index behaviour so the traffic and rankings you already have carry over.
Host, monitor and hold performance
Hosted and managed on our own platform where it is our build, kept fast, secure and technically healthy as the site grows and the content changes.
How we approach Next.js websites.
Server-rendered by default, not client-side
We render pages to HTML on the server with React Server Components and static generation, so a crawler or an AI assistant receives your content on the first request instead of a blank shell it has to execute JavaScript to fill. That is the difference between a Next.js site that ranks and one that quietly does not.
Fast because the framework is used well
next/image, next/font, route-level code splitting and streaming are used the way they are meant to be, so Core Web Vitals hold on real devices under a real page weight, rather than a launch-day score that collapses once the site is populated.
Structured to rank and be cited
Semantic HTML, the Metadata API for titles and canonicals, and JSON-LD schema built into the layout, so search engines and assistants can read entities, resolve canonicals and quote your pages rather than guessing at them.
Rendering chosen per route, not one blanket mode
Static, incremental regeneration or server rendering is decided page by page against how the content changes and how it needs to be found, instead of forcing the whole site into one strategy that suits neither the marketing pages nor the dynamic ones.
What Next.js websites puts on your desk.
Who builds your Next.js site, and how
Rogue Logic is the trading name of Bryley Ltd, a team of four senior practitioners with roughly forty years of combined experience between them. Your Next.js build is scoped, designed and engineered by the people who have done it before and who also do the SEO, so the framework is used the way search needs it read, not the way a tutorial demonstrates it. We are honest about what we do and do not take on.
Senior hands on the build
Rendering strategy, the server and client boundary, migration planning and structured data are judgement calls, so they sit with experienced practitioners rather than a checklist run on autopilot.
Built by people who also rank sites
We build Next.js and we do the technical SEO, so the framework is used to serve crawlable HTML and strong Core Web Vitals, not just to pass a component demo. The two are the same conversation here.
Honest about scope
We build marketing-led Next.js sites exceptionally well and host what we build. If you need a large bespoke web application, we will tell you plainly that it is a better fit elsewhere rather than selling you a build that is not ours to run well.
Next.js websites: common questions.
How much does a Next.js website cost?
Bespoke Next.js builds start at £5,000 plus VAT, scoped to your site and how the content behaves, with hosting and management on our own platform from £100 a month where it is our build. We price it properly on a call once we understand the site, rather than quoting a headline number that changes later.
Is Next.js good for SEO?
Yes, when it is built correctly. Next.js can render your pages to HTML on the server with static generation and server components, which is exactly what search engines and AI assistants need. The risk is a Next.js site built as a client-rendered app, where content only appears after JavaScript runs. We build server-first so your pages are readable on the first request.
What is the difference between the App Router and the Pages Router?
The App Router is the newer model built around React Server Components, layouts and streaming, and it is where most new Next.js builds should start. The Pages Router is the older approach still widely in use. We build on the App Router by default and can work within a Pages Router codebase you already have, choosing whichever serves your site rather than rebuilding for its own sake.
Will the site pass Core Web Vitals?
Yes. Speed in Next.js comes from using the framework properly: next/image for responsive lazy imagery, next/font to remove layout shift, route-level code splitting and streaming to cut hydration cost. We measure on real devices with a real page weight, not a stripped demo, because that is where performance usually breaks.
Can you build a Next.js site with a headless CMS?
Yes. Next.js pairs naturally with a headless CMS, and we integrate the two so editors get a clean workflow and preview without shipping the CMS's weight to the browser or breaking the render strategy. We scope the right CMS around how your team actually publishes.
Can you rebuild our existing site in Next.js without losing rankings?
Yes. Replatforming is where rankings vanish if the redirects are wrong, so we migrate with a full URL map and redirect plan, handled in next.config or middleware, launch behind it, and verify against live crawl and index behaviour so the traffic you already have carries over.
Do you build the site so AI assistants can read and cite it?
Yes. We render pages to HTML on the server, use clean semantic markup and JSON-LD schema, and resolve canonicals and entities consistently, so assistants can read, understand and cite your content. These are the same foundations that win classic search, not a separate trick bolted on.
Do you host and maintain the Next.js site?
We host and manage the sites we build on our own platform from £100 a month, kept fast, secure and technically healthy as the site grows. We do not take on hosting for sites built elsewhere, because we can only stand behind performance on a build that is ours.
