Web Design & Development
for sites machines can actually read.

Most agency websites are designed first and made findable afterwards. We build the other way round, so the HTML your server returns already contains the content search engines and language models are looking for.

First fetch, JavaScript not executed

Client-side build

  • 1 <div id="app"></div>

Server-rendered build

  • 1 <h1>Web design and development</h1>
  • 2 <main> with the full page copy inside
  • 3 <script type="application/ld+json">
readable on first request no script execution required
Illustrative example. It shows one page built two ways, and what a crawler receives from each before any JavaScript runs.

Build decisions that decide whether machines can read you

  • Server-Rendered HTML
  • Core Web Vitals
  • Semantic Markup
  • Structured Data
  • Accessibility
  • Conversion Paths
  • CMS Handover
  • Migration Safety

Our build strategy

  1. 01

    Decide what renders where

    Before a single screen is designed, we settle which pages the server returns complete and which parts may load afterwards.

  2. 02

    Write markup for two readers

    Semantic elements and structured data, so a person and a parser take the same meaning out of one page.

  3. 03

    Protect what already ranks

    Redirect maps and URL preservation planned during the build, then proven by a crawl comparison before launch.

  4. 04

    Hand it over properly

    Editors get a CMS they can use on their own, and your team gets the documentation to run the site without us.

Web design and development is the work of turning a business case into a working website: the page structure, the interface, the code that renders it, and the system your team edits it in. We treat the HTML a machine receives as part of that design, which is why this work sits so close to organic SEO and Performance SEO rather than being handed over to them afterwards.

Designed first, made findable afterwards, paid for twice

Rendering, markup and URL structure get decided while the site is being built. Changing any of them once it is live means opening the same templates a second time and paying for the same work again.

The empty container problem

A site that renders content only after JavaScript runs looks complete in your browser and blank to anything that does not execute scripts. Plenty of crawlers skip that step, and language models frequently skip it too.

Retrofits cost more than decisions

Adding server rendering, semantic structure or Schema & Structured Data to a finished build means reopening templates, reworking content and sometimes replacing the platform underneath both.

Two audiences, one set of files

Headings, landmarks and link text carry meaning for a person using a screen reader and for a model summarising your page. One set of build decisions serves both audiences when it is made early enough.

Five build decisions and what they cost you later

Every row below is inexpensive to get right during the build. Each one becomes a project of its own once the site is live and the content team has moved on.

Build decision What it costs you later
Client-side rendering only Crawlers and language models receive an empty container. Your copy lives in the browser and is absent from the response those readers actually parse.
Generic div markup Navigation, headings and main content become indistinguishable. Parsers guess at the outline of the page, and assistive technology has nothing to announce.
No structured data Your services, locations, prices and authors stay implicit. Engines either infer them from prose or leave them out of the answer altogether.
Unplanned URL changes External links, bookmarks and years of accumulated signals point at addresses that no longer resolve. Rankings earned over years reset on launch day.
Inaccessible components Keyboard users get trapped, screen readers announce the wrong thing, and you carry a legal exposure that grows every time someone adds a page.

Who this is for

This work pays off where the website carries real commercial weight and where losing its visibility would be felt within a quarter.

Teams planning a redesign

You have a site that earns traffic and a design that has aged out. The risk is not the visual work, it is the URL structure underneath it. Planning the migration before the first mockup is what keeps the traffic you already paid for.

Brands that AI answers never mention

Competitors show up when someone asks an assistant about your category and you do not. Where the cause is a page that only exists after JavaScript runs, no amount of content work fixes it until the rendering changes.

Sites that outgrew their template

Every change needs a developer, the page builder fights the layout, and nobody wants to touch the header. That friction shows up as stale content, which then shows up as declining visibility.

Businesses with an accessibility deadline

You have been told the site needs to meet a standard and you need to know what that means in practice. We audit against the criteria, fix the components, and document what was changed so you can evidence it.

How we build

Six stages, each one ending in something you can open, read or click. Nothing moves forward on a verbal agreement.

  1. 1

    Discovery and scope

    We write down what the site has to achieve, who edits it, what has to migrate and what can be retired. That document is the reference everything later gets checked against.

  2. 2

    Architecture and URL plan

    Page structure, internal linking and the full URL list, including which existing addresses stay exactly as they are. Redirect mapping starts here rather than the week before launch.

  3. 3

    Design against real content

    Layouts drawn around the copy, headings and data the site will actually carry. Designing with placeholder text is how components end up unusable for the people who fill them.

  4. 4

    Build with rendering settled

    Templates that return complete HTML, semantic elements throughout, and structured data written alongside the markup it describes instead of being appended once the build is signed off.

  5. 5

    Pre-launch crawl and accessibility pass

    We crawl the live site and the staging build, compare the two, and resolve every URL that lost a destination. In parallel the interface is tested by keyboard and with a screen reader.

  6. 6

    Launch, monitor, hand over

    We watch indexing, errors and Core Web Vitals through the first weeks, then hand your team the documentation and training needed to run the site independently.

Questions we get asked

Why does server-rendered HTML matter for AI search?

Many crawlers and language models read the HTML your server returns and never execute JavaScript. If your copy, headings and links only appear after a script runs, those readers receive an empty container. Server rendering puts the content in the first response, which is where LLM SEO starts.

Will a redesign lose the rankings we already have?

It can, and most of the damage traces back to URLs. We map every existing address to its new home, keep the URLs that already earn traffic, and crawl the old site against the staging build before launch so a missing page is caught while it is still cheap to fix.

Do you build on WordPress or a custom stack?

Both. WordPress suits teams who publish often and want to edit without a developer. A custom or headless build suits products with complex data or unusual performance needs. We choose after we understand who edits the site, how often, and what the content actually has to do.

Is accessibility a legal requirement or a nice to have?

In the European Union the Accessibility Act covers many consumer facing services, and public sector bodies already have duties under the Web Accessibility Directive. Beyond the law, the markup that helps a screen reader announce your page also helps a parser understand it.

How long does a build take?

It depends on page count, how much content still needs writing, and how many systems sit behind the site. A focused marketing site moves faster than a catalogue with thousands of URLs. You get a dated schedule after discovery, once the scope is written down and agreed.

Can you improve our current site instead of rebuilding it?

Often, yes. Where the platform is sound, we fix rendering, markup, structured data and speed on what you already have, which overlaps with our Performance SEO work. A rebuild earns its cost when the template system fights every change.
