Good design is invisible. When a website is designed well, visitors don't notice the design at all — they just find what they came for and get in touch. When it's designed badly, they leave. Here are the non-negotiables that separate a website that converts from one that just looks nice on a portfolio page.
Good design gets out of the way
A visitor lands on your site with one of three questions: can this business solve my problem, can I trust them, and how do I contact them? Everything on the page should exist to answer one of those three questions faster. If a design element doesn't, it's noise — and noise is what makes people leave.
The non-negotiables
- Speed. A homepage that loads in under two seconds on a mid-range phone on 4G. Anything slower and both Google and your visitors quietly punish you — see our guide on why PageSpeed Insights matters.
- Mobile-first layout. More than 70% of small business traffic is now mobile. If the mobile version feels like an afterthought, so does the whole business.
- Clear navigation. Five or six top-level items maximum. Every visitor should be able to name your services in under ten seconds.
- One obvious next action per page. "Call us", "Get a quote", "Book a chat" — not all three, competing.
- Real content. Actual photos, real testimonials, specific numbers. Stock imagery and vague promises kill trust faster than an ugly font.
Accessibility isn't optional anymore
None of this makes a site look worse. Done properly, an accessible site is a better site for every visitor — clearer typography, more logical structure, faster interactions. If a designer treats accessibility as an add-on, they're building you a site that will fail its next audit.
Design that's built to convert, not just to look good
That means clear pricing (or at least clear guidance towards it), obvious contact routes on every page, real proof of past work, and calls-to-action that use the visitor's language, not marketing jargon. "Start a project" beats "Engage our services" every time.
Quick self-audit: 5 questions to ask about your current site
- On mobile, does the homepage load in under 2 seconds on a normal connection?
- Within 10 seconds of landing on the homepage, does a first-time visitor understand what you sell and who it's for?
- Is there one obvious next action above the fold on every page?
- Does the site work — genuinely — on a phone as well as it does on a laptop?
- If a customer wanted to contact you right now, could they do so in a single tap from any page?
One "no" is fine. Three or more and the site is quietly costing you enquiries every month.
