SEO website design: What it is and 5 things to look for before you hire a designer

A beautiful website that nobody can find is an expensive brochure.

I’ve watched it happen more than once. A business invests in a new site, the launch-day photos look wonderful, and six months later the enquiries haven’t changed, because the site was designed to be looked at rather than found on search engines and large language models like ChatGPT and Claude.

That’s the gap SEO website design is meant to close. But the phrase gets used loosely, and plenty of designers say they “do SEO” when they mean they’ll add a plugin and fill in a few meta tags. So before you hire anyone, it helps to know what the term should actually mean, and what to look for.

I spent seven years as Head of Content at an ultra-luxury marketing agency, and nearly a year running my own marketing agency, so I’ve seen what happens to good-looking websites that were never built to be discovered.

What is SEO website design?

SEO website design (also called SEO web design, or simply web design and SEO ) is the practice of planning and building a website so that search engines can find, understand and rank it, while it still looks and works beautifully for the people who visit.

In a typical website design project, design and search sit in separate boxes. The designer makes decisions about layout, structure, page names and imagery. Search engine optimisation is dealt with afterwards, if at all. In SEO-friendly web design, those decisions are made with search in mind from the first conversation, because many of them are hard to change later, with the SEO specialist and designer working closely together.

That doesn’t mean the site is designed for Google instead of people. Good website design and SEO pull in the same direction far more often than they conflict: clear structure, fast pages, sensible navigation, genuinely useful copy. All of it feeds the same goals, which are a better user experience for visitors and more organic traffic for you. The skill is in doing both properly.

It also helps to see where this sits in the bigger picture. A website is the hub of your digital marketing: your social posts, PR, email and ads all send people there. If the hub is slow, confusing or invisible in search, every other channel works harder than it should.

1. Start with research, not with a mood board

The first question a genuine SEO web designer asks isn’t “what colours do you like?” It’s “who are you trying to reach, and what are they typing into Google?”

Before a single page is designed, there should be keyword research covering:

the words and phrases your potential customers actually use (which are often not the words you use)
what they expect to find when they search those phrases, which is what the search engine results pages (SERPs) tell you about intent
what the sites currently ranking for them look like
which of those searches are realistic for your site to compete for, and which are a long game, because search ranking is always relative to the competition

This research shapes everything that follows: which pages exist, what they’re called, and what each one needs to say. If a designer goes straight to visual concepts with no mention of search terms, that tells you something.

2. Site structure planned around how people search

The architecture of a website, meaning its pages, URLs, menus and the links between them, is one of the biggest influences on how well it performs in search, and it’s one of the hardest things to change once the site is live.

A well-planned structure gives each important service or topic its own page, with a clear purpose and a clear search target. It uses a URL structure that makes sense to a human reader (a short, descriptive address rather than a string of numbers). It links related pages together so that both visitors and search engines understand how everything fits.

That last point is about crawlability. Crawlers, the automated programmes search engines use to discover and read pages, follow links from page to page. If an important page is buried several clicks deep, or isn’t linked from anywhere, crawlers may never reach it, however good it is. A sensible structure makes your site easy to crawl, and that’s the first step towards it appearing in search results at all.

The classic mistakes are one page that tries to do everything (“Services” with six offerings crammed onto it, each competing for attention and none ranking for anything) and two pages that target the same search term and end up competing with each other instead of the competition.

3. The technical foundations are right, on whichever platform you choose

You don’t need to become an expert in this, but you do need a designer who is. Technical SEO is the behind-the-scenes work that lets a site be found and used, and the basics that should be in place before launch include:

Speed. Loading speed, page speed, website speed and loading time are all describing the same thing: how quickly your pages become usable. Slow pages frustrate visitors, who tend to leave before they’ve seen anything, and that pushes your bounce rate up. Speed also feeds into the overall experience Google wants to reward, so it matters twice over. Ask how the designer keeps images, code and plugins lean.
Responsive design and mobile responsiveness. Most people will meet your site on a phone first. Responsive design means the layout adapts properly to every screen size. Genuine mobile responsiveness goes beyond shrinking a desktop page: buttons should be easy to tap, text easy to read and forms easy to complete.
Clean subheadings. Each page should have one main heading and a logical set of subheadings beneath it. They help readers scan, and they help search engines understand what each section covers.
Meta tags. Descriptive page titles and meta descriptions, written individually rather than left as defaults, tell searchers what a page is about before they click.
Alt tags. Alt text on images (often called alt tags) helps visitors who use screen readers and gives search engines context for pictures they can’t otherwise interpret.
Search tools connected from day one. A sitemap submitted to Google Search Console, plus analytics, so you can see how the site is performing from the first week.
Structured data (schema) where it’s relevant to your business.

Here’s the part most people don’t realise: platforms differ in what they make easy. Popular platforms like WordPress, Shopify, Framer, Squarespace and Wix can all support an SEO-friendly website, but each has its own quirks, strengths and limits, and a template site and a fully custom build are very different propositions. A good designer will tell you honestly what your chosen platform can and can’t do, and won’t pretend they’re all identical.

4. Words planned alongside the design

Search engines read words. A site designed around placeholder text that is swapped for real copy two days before launch is almost always a site that underperforms, because the layout was never shaped around what the pages actually need to say.

In SEO-led web design, the content is considered early. That means thinking about how much space each page needs, where the key message sits, how questions are answered, and where the internal links go. It also means the copy itself needs to be good: clear, specific and written for a person first.

Good copy also does a commercial job. The best-ranking page in the world is wasted if visitors don’t know what to do next. Clear calls to action, honest descriptions and well-placed proof are what lift your conversion rate, meaning the share of visitors who go on to enquire or buy. Traffic is only half of the picture.

This is where my own background shows. I’ve spent a career making words work hard, and it’s the part of a website that is most often rushed.

5. Full ownership with a plan for after launch

Two things matter enormously and are rarely discussed at the quote stage.

Ownership. You should own your website, your domain, your content and your accounts. If you part ways with your designer, you should be able to take everything with you. Be wary of arrangements where the site only exists on someone else’s hosting, or where the access details are held by someone else. Hosting is usually managed directly through the website platform you choose, in your name, which keeps things simple and keeps control with you.

What happens next. A launch is the start of the process, not the end of it. Search ranking takes time to build, and a new site rarely takes off on its own. Over the following months, the things that move the needle include fresh content, such as regular blog posts, and backlinks, which are links from other reputable websites pointing to yours that act as a signal of trust.

The best designers can tell you how the site’s performance will be tracked in Google Search Console, how new content will be added, and who is responsible for the ongoing work. Ideally the answer isn’t “that’s a separate project”, with a handover to someone who has never seen the site.

And a note of caution: nobody can promise you a first-page ranking, whatever they say in the pitch. What a good designer can promise is that the site will be built properly, so that you’re giving yourself the best possible chance.

If you’re planning a new site, or you’re not sure why your current one isn’t bringing in enquiries, get in touch. I’m happy to talk through what you actually need, including what you don’t.

SEO Website Design: FAQs

What is SEO website design?

It’s the practice of planning and building a website so that search engines can find and understand it, while keeping it attractive and easy to use. Search decisions such as page structure, URL structure and copy are made at the start of the project rather than after launch.

Is SEO web design different from normal web design?

The visual skills are the same. The difference is in the planning: keyword research, a page structure built around those searches, technical foundations such as page speed and mobile responsiveness, and content planned alongside the design, not bolted on after.

Does SEO website design guarantee a first-page ranking?

No. Nobody can honestly promise a particular position. A well-built site gives you a strong foundation, but search ranking depends on competition, content and authority, and it takes time to build.

Which website platform is best for SEO?

WordPress, Framer, Squarespace and Wix can all support good SEO. The right choice depends on your business, how much control you need and how the site will be managed. A good designer will explain the trade-offs rather than recommending one platform for everyone.

Should I redesign my site or fix the SEO on my existing one?

It depends on what’s wrong. If the structure, platform or content is the problem, a rebuild may make sense. If the foundations are sound, improving the existing pages can be quicker and cheaper.
