If your site feels fine but enquiries are flat, a structured website audit, sometimes called a web design audit when the focus is layout, UX and visual hierarchy, is the fastest way to find out why. This 2026 guide walks through the full process, accessibility, user experience, user interface, brand consistency and performance, so you can fix what matters before spending on a redesign.
You can run most of this yourself with free tools and a few hours. When you need an independent expert review, especially before a rebuild, a professional website design audit adds judgement that automated scans cannot replace.
What a website audit covers
A website audit checks whether your site works for real people and supports your business goals. It is not a single Lighthouse score or a plug-in report, it is a structured review across five areas:
- Accessibility, can everyone use the site, including people who rely on keyboards or screen readers?
- User experience (UX), can visitors find what they need quickly on desktop and mobile?
- User interface (UI), is the visual design clear, consistent and responsive?
- Brand consistency, do logos, colours, fonts and tone match across every page?
- Performance and functionality, does the site load quickly, work in major browsers and link correctly?
Before you start checking boxes, write down what the site needs to achieve. An audit for lead generation looks different from one for e-commerce checkout or brand credibility, and that scope keeps the process honest.
Accessibility standards
Ensuring your website meets accessibility standards is essential for making your content available to all users, including those with disabilities. In 2026, WCAG 2.2 remains the reference most UK businesses aim for, even if full compliance is a longer project than a single afternoon audit.
Check for text readability
Text readability starts with contrast. Use a tool like colourcontrast.cc to check text against background colours, insufficient contrast is one of the most common failures on SME sites. Pair that with legible fonts and sizes large enough to read without zooming.
Test for keyboard navigation
Many users navigate with a keyboard alone. Tab through every interactive element, links, buttons, form fields, and confirm focus indicators are visible. Avoid autoplaying animations that flash or blink; they distract users and can trigger seizures in people with photosensitive epilepsy.
Assess alternative text for images
Every informative image needs descriptive alt text that conveys its purpose. Decorative images should use an empty alt attribute (alt="") so screen readers skip them. Missing or generic alt text ("image1") is a quick fix that improves both accessibility and image SEO.
Review form elements
Forms must have clearly associated labels, logical tab order and accessible error messages. Test validation states, if an error appears, can a screen reader user understand what to fix without guessing?
Clear page titles
Each page needs a unique, descriptive <title> and heading that reflects its content. Vague titles like "Home" or "Services" waste a chance to orient users and search engines.
Descriptive links
Avoid "click here" or "read more" without context. Link text should describe the destination, for example, "Read our UX design principles guide" or "Download the annual report."
Top tip: Google PageSpeed Insights includes an accessibility audit that catches many of these issues automatically, use it as a starting point, not the full picture.
User experience (UX)
User experience determines whether visitors stay, explore and convert. A positive UX supports engagement; a frustrating one sends people back to search results, regardless of how polished the visuals look.
Assess navigation
Navigation should be intuitive and consistent across pages. Check that your site hierarchy is logical, general topics at the top, specific pages nested beneath, and that important destinations are reachable within three clicks from the homepage.
See below for examples of clear versus confusing site structure:
Evaluate load times
Page speed affects both satisfaction and search visibility. Measure load times with PageSpeed Insights and note Google's Core Web Vitals thresholds: Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1. Compress images, enable caching and consider lazy loading for below-the-fold media. Some fixes need a developer. Start a project if you want help prioritising technical work.
Analyse mobile responsiveness
Test on real phones and tablets, not just browser resize tools. Touch targets should be large enough to tap without misclicking, and layouts should reflow without horizontal scrolling. Mobile traffic often exceeds desktop for UK service businesses, if the mobile experience is weak, the audit has found its first priority.
Examine content layout
Content should scan easily. Use headings, subheadings and bullet points to break up long paragraphs. If users cannot find the answer within a few seconds of landing, the layout needs work, not more copy.
Test interactivity
Buttons, links and forms should provide clear feedback on hover, focus and click. Test every interactive element on both desktop and mobile. Broken or unresponsive controls are conversion killers that a visual review alone will miss.
Enhance user interface (UI)
The user interface covers the visual layer, layout, colour, typography and interactive styling. A strong UI supports UX; a cluttered or inconsistent one undermines it.
Consistent visual design
Use a consistent colour scheme, font styles and imagery treatment across all pages. Inconsistency makes sites feel unfinished and erodes trust, especially when landing pages look nothing like the homepage.
Clear and intuitive layout
Important elements should be easy to find. Use white space deliberately rather than filling every pixel. Clutter does not build comfort, it increases cognitive load and makes users work harder to find what they need.
Responsive design
UI elements must adapt cleanly across screen sizes. Test navigation menus, image crops and form layouts at common breakpoints, not just desktop and mobile extremes.
Visual hierarchy
Size, colour and placement should signal what matters most. Primary actions. "Get a quote", "Book a call", should be visually obvious without competing with secondary links.
Interactive elements
Buttons and links need distinct styles and hover/focus states. If users cannot tell what is clickable, they will miss your CTAs.
Font choice
Use clear, legible web fonts. Google Fonts offers a wide range of open-source options. Confirm text contrast meets accessibility standards, a beautiful typeface at 12px light grey on white fails the audit even if it looks elegant.
Minimise distractions
Avoid excessive animation or flashy elements that pull attention from the main message. Engaging and overwhelming are different things, aim for the former.
Maintain brand consistency across pages
Brand consistency means logos, colours, fonts and messaging feel like the same business on every page. An audit spots drift, a blog that uses different colours, a landing page with an old logo, product pages with off-tone copy.
Consistent visual design
Check that colours, fonts and imagery follow your brand identity guidelines, or, if you do not have guidelines yet, that choices are at least consistent site-wide.
Check branding across pages
Verify logos, taglines and key messages match on the homepage, service pages, blog and footer. An outdated logo on one template is a common find on sites that have evolved without a full refresh.
Evaluate tone and voice
Content should sound like one brand, not a different writer on every page. Note where tone shifts from formal to casual without reason.
Assess logo and icon usage
Logos need correct clear space, minimum sizes and approved variants. Custom icon sets that match your brand strengthen recognition; mismatched stock icons weaken it.
Performance and functionality
Performance issues frustrate users and waste marketing spend, sending paid traffic to a slow site is an audit finding in itself.
Evaluate website speed
Analyse load times with Google PageSpeed Insights or GTmetrix. Identify slow assets, oversized images, unminified scripts, slow server response, and fix the biggest bottlenecks first. Speed improvements often deliver the fastest ROI of any audit fix.
Check for broken links
Broken internal and external links harm credibility and SEO. Use a broken-link checker to scan the site regularly. Fix or redirect dead pages rather than leaving 404s in navigation.
Test browser compatibility
Test in Chrome, Firefox, Safari and Edge, current and one version back. Layout shifts, font rendering issues and JavaScript errors often appear in one browser but not another.
Documenting findings and implementing changes
Findings without a plan become a forgotten spreadsheet. Use this five-step process to stay organised:
1. Create an audit report checklist
Document each issue with a description, severity (critical, major, minor), affected URL and a screenshot where helpful.
2. Prioritise the order of issues
Rank by severity and user impact. Accessibility failures and broken conversion paths come before cosmetic tweaks.
3. Develop a fix list
Cross-reference your findings with this guide and tool recommendations. Write the fix next to each issue so implementation is faster.
4. Implement changes
Work through the list systematically, critical items first. Batch similar fixes (all alt text updates, all contrast changes) to save time.
5. Re-audit the website
Re-test with the same tools and methods. Confirm fixes worked and check that nothing new broke in the process.
Bonus: monitor regularly
Schedule periodic audits, quarterly works for most active business sites. Set up uptime monitoring and run PageSpeed checks after major content or design changes.
Website audit FAQs
How do you do a website audit?
Start by defining what the site needs to achieve, leads, sales, bookings or credibility, then audit accessibility, UX, UI, brand consistency and performance in that order. Use free tools for speed and contrast checks, walk key user journeys manually on desktop and mobile, and record every issue with a screenshot and severity rating before you fix anything.
What is the website audit process?
The standard website audit process is: scope your goals, review each area (accessibility, UX, UI, brand, performance), document findings in a checklist or report, prioritise by impact and effort, implement fixes starting with the highest-severity items, then re-test with the same tools to confirm the issues are resolved. Schedule periodic re-audits, quarterly is reasonable for active sites.
What does a website audit include?
A thorough audit includes text contrast and readability, keyboard navigation, image alt text, form labels, navigation hierarchy, page load times, mobile responsiveness, visual design consistency, brand alignment across pages, broken links, browser compatibility and Core Web Vitals. It does not automatically include user testing with recruited participants or a full SEO content strategy, those are separate scopes.
How do you audit your website for UX?
Walk the paths your visitors actually take, homepage to contact, product to checkout, blog to enquiry, and note anywhere you hesitate, misclick or lose context. Check menu depth (important pages within three clicks), load times on mobile, touch target sizes and whether headings and CTAs make the next step obvious. Compare your site structure against a logical hierarchy, not just what looks fine to you.
How much does a website audit cost?
DIY audits cost nothing beyond your time and free tools. Professional website design audits from UK studios are typically quoted per project, scope, site size and depth of review all affect the price. Berlew audits are quoted individually; we deliver a written, prioritised report rather than an automated scan. Avoid treating a free Lighthouse PDF as a full audit, it catches technical signals but not whether the site actually converts.
When should I get a professional website design audit?
Call in expert help when you have traffic but weak enquiries, you are planning a rebuild and want to avoid repeating the same mistakes, or your internal team is too close to the site to spot confusing navigation and weak hierarchy. A professional audit is also worth it when accessibility compliance matters for your sector or when stakeholders need an independent, prioritised plan they can brief against.
Conclusion
A thorough website audit improves accessibility, user experience, brand consistency and performance, the foundations that turn traffic into enquiries. DIY audits catch most obvious issues with free tools and structured checklists. When you need independent expert judgement, especially before a rebuild or when conversions lag despite decent traffic, a professional website design audit delivers a prioritised plan you can act on.
