Web Design Tips: 10 Simple Tips That Improve Conversion

Looking for a web design tip that actually moves enquiry numbers? I am Lewis. Creative Director at Berlew Design Studio, a web design agency in the UK, and these are ten practical changes we see make a difference on real business sites.

If you run a business, a website that converts visitors into customers or leads is not optional. Research cited by Sixth City Marketing suggests about 75% of people judge a website's credibility from its design alone, and users can form a first impression in roughly 0.05 seconds. That does not mean design guarantees sales; your offer, pricing and follow-up still matter. It does mean avoidable friction, slow pages, confusing menus, weak mobile layouts, costs you enquiries before anyone reads your pitch.

This updated July 2026 guide walks through ten simple web design tips that improve conversion. Work through them as a checklist, measure what changes, and keep what your analytics support.

10 Web Design Tips That Improve Conversion

1. Keep It Clean and Simple

Less is more. A clean, simple design is easier to scan and helps users find what they need quickly, which matters when attention is scarce.

Cluttering pages with too much information, competing buttons or flashy graphics rarely helps conversion. Strip back to what supports the journey: a clear headline, proof where sceptical visitors need it, and one primary action per section. If you want a broader checklist beyond conversion, our top 10 website design tips guide covers UX, SEO and when to bring in professional help.

2. Make It Mobile-Friendly

Most UK visitors browse on phones. A mobile-friendly website is not a nice-to-have, it is baseline credibility.

Responsive design means your site adapts cleanly whether someone is on a phone, tablet or desktop. Test on real devices: text should be readable without zooming, buttons large enough to tap, and forms usable with one thumb. A clunky mobile experience sends people back to search results. For why mobile-first discipline matters for rankings and usability, see why mobile-first design is essential and our responsive web design golden rules.

3. Obvious Calls to Action

Calls to action (CTAs) are signposts, they tell visitors what to do next. If they are vague or buried, conversion suffers.

Make primary CTAs visually distinct: strong contrast against the background, action-oriented labels ("Book a call," "Get a quote," "Start a project") and placement where people naturally pause, after a value proposition, not only in the footer. One clear primary action beats three competing buttons. Keep copy short; the surrounding page should do the persuading.

4. Speed Things Up

A slow site is a conversion killer. Every extra second of load time gives visitors a reason to leave.

Compress large images, enable caching, audit third-party scripts and consider a content delivery network if you serve visitors across regions. Google PageSpeed Insights shows where your pages lag. Quick loads keep people reading long enough to convert, and support UX for SEO signals too. Speed fixes often outperform a visual re-skin alone.

5. Smooth Navigation

Navigation is your site's map. If people cannot find services, pricing or contact details within a few clicks, design polish will not save the enquiry.

Use familiar menu labels. "Home," "About," "Services," "Work," "Contact", and keep top-level items focused. Dropdowns help when you have depth, but too many options create decision fatigue. Put your navigation where people expect it (usually top of page), keep layout consistent across pages, and add search if you publish a lot of content. Breadcrumbs help on deep pages.

Test with someone who has never seen your site. What is obvious to you may not be obvious to a first-time visitor. If you are unsure where friction hides, a structured website audit is a sensible starting point.

6. Stick to Your Branding

Consistent branding builds recognition and trust, both of which support conversion.

Colours, fonts and your logo should align across every page. When a site looks disjointed, visitors wonder whether the business behind it is equally scattered. If your logo uses a specific blue, use that blue for buttons and accents. Limit fonts to one or two families. Match tone of voice, casual or formal, across headings, body copy and CTAs.

Place your logo where people expect it (typically top left, linking home). Consistency is not vanity; it signals that you are a real, considered business. For how visual identity fits the bigger picture, see logo design vs brand identity.

7. Apply Visual Hierarchy

Visual hierarchy directs attention to what matters most, headline, proof, then action.

Use size, colour, contrast, spacing and placement deliberately. Bold headlines should lead; supporting copy should recede. CTAs should sit in the visual path, not compete with decorative elements. A strong hierarchy makes pages scannable on mobile and desktop alike, visitors grasp your offer before they decide to leave.

This overlaps with UX design principles we apply on client projects: hierarchy is how you guide behaviour without shouting.

8. Use Top-Notch Images

High-quality images hold attention and reinforce professionalism. Blurry, generic or off-brand visuals undermine trust.

Prefer unique photography where budget allows; stock can work when it matches your sector and feels authentic. Always optimise file size, high resolution does not mean multi-megabyte uploads. Tools like TinyPNG help compress without visible quality loss.

Place images to support content, not distract from it. Break up long text, illustrate services, show real work. Sites like Unsplash and Pexels are useful sources when you need placeholders, but relevance beats volume.

9. Try A/B Testing

A/B testing lets you compare two versions of a page, different button colours, headlines or hero images, and keep what performs better.

Change one element at a time. If you alter button colour, headline and layout simultaneously, you will not know which change moved the needle. Google Analytics (or your analytics platform of choice) tracks results. Run tests long enough to gather meaningful traffic; small sites need patience.

Testing is continuous improvement, not a one-off project. The goal is to learn what your audience responds to, not to chase vanity metrics. Pair tests with qualitative feedback when you can: watch session recordings or ask recent enquirers what almost stopped them.

10. Add Some Social Proof

People trust other customers more than marketing copy. Reviews, testimonials, client logos and awards reduce perceived risk at decision points.

Place credible proof near CTAs, not only on a buried testimonials page. Embed recent Google reviews, show logos of recognisable clients (with permission), and highlight certifications where relevant. Video testimonials can work when they are short and specific.

Keep social proof current. Outdated reviews or stale case studies can signal neglect. If you showcase work visually, our guide on building a design portfolio that converts covers how proof supports trust beyond a logo strip.
