Send enquiryWebsite accessibility means building a website so people with different abilities can perceive, understand, navigate and use it. When design ignores this, visitors meet barriers: text they cannot read, buttons they cannot reach, forms they cannot complete.
A practical example: A customer who uses a screen reader opens your contact page. The form fields have no labels, so the reader only says "edit text, edit text." She cannot tell where to type her name or phone number, and leaves. A few correct labels would have fixed it.
This guide explains accessible website design, the WCAG guidelines, 15 essential practices, a checklist and a testing process. Accessibility works best when planned from the start, as covered in custom vs template-based websites.
An accessible business website has readable contrast, text alternatives for images, full keyboard use, clear headings, labelled forms, captioned video, simple navigation, responsive layouts and clean semantic code. It is tested manually and with tools, and reviewed after updates. General practices like these support inclusion but do not by themselves prove legal compliance.
Website accessibility, also called web accessibility, is the practice of designing and developing websites that work for people with different abilities. It covers permanent, temporary and situational needs.
| Term | Meaning | Focus |
|---|---|---|
| Accessibility | Removing barriers so people with disabilities can use the site | Access for specific needs, often guided by WCAG |
| Usability | How easy and efficient a site is for its intended users | Ease, speed and satisfaction for all users |
| Inclusive design | Designing from the start for the widest range of people | Diversity of ability, language, device and context |
Accessibility does not automatically bring better SEO, more conversions or legal compliance. Legal requirements vary by country and sector, so seek qualified advice for your situation.
The standard
The Web Content Accessibility Guidelines (WCAG) are an international set of recommendations for making web content accessible. Many website accessibility standards and policies refer to them. They are built on four principles, often remembered as POUR.
| Level | General meaning |
|---|---|
| A | The most basic requirements. Without them, some users cannot use the content at all. |
| AA | A stronger level that addresses the most common barriers. Often referenced as a practical target. |
| AAA | The highest level. Not always achievable for all content, so it is rarely required for a whole site. |
Which level applies to your business depends on your sector, location and any rules or contracts that apply to you. These four principles are an introduction, not a substitute for a full WCAG assessment.
The 15 practices
These website accessibility best practices form the core of any accessible business website. Each shows what it means, how to apply it and what to avoid. For wider design planning, see website design and development.
Text must stand out from its background, and so must buttons, icons and form borders. Low-contrast text is hard to read for people with low vision, and for anyone in bright light. WCAG sets minimum contrast ratios that depend on text size and element type, so check them with a contrast tool.
Screen readers read alt text aloud, so informative images need a short description of their purpose. Purely decorative images should have empty alt text (alt="") so they are skipped.
Many people cannot use a mouse. Everything must work with the keyboard: Tab and Shift+Tab to move, Enter and Space to activate, Escape to close menus or dialogs. Order should be logical and focus always visible, with no keyboard traps.
Screen reader users often jump from heading to heading to scan a page. Use one meaningful H1, then H2 and H3 in order, and use real heading tags only for headings.
Forms are where enquiries and sales happen. Each field needs a visible, properly linked label, clear instructions, a marked required status and helpful error messages.
Captions help people who are deaf or in noisy places. Transcripts help audio-only content, and audio description helps blind users when visuals carry meaning. Automatic captions often need human review.
Screen reader users can list all links on a page. "Click here" repeated ten times means nothing out of context. Links go somewhere; buttons do something, and should look and act that way.
Consistent menus in the same place on every page help everyone, especially people with cognitive disabilities. Provide a skip-to-content link, breadcrumbs where useful and clear labels.
Comfortable size, spacing and line length reduce effort. Use readable fonts, generous line spacing and short paragraphs, and let users resize text without losing content.
Many users zoom the page or use small screens. Layouts should reflow at narrow widths without sideways scrolling, and key functions must remain available on mobile.
People with colour blindness may not tell red from green. Errors, statuses, charts and required fields should also use text, icons or patterns.
Buttons, dropdowns, modals, tabs, accordions and menus need clear names, states (open, closed, selected) and sensible focus management. Test them with a keyboard and screen readers, not by eye alone.
Native elements such as header, nav, main, footer, button, a, lists and tables carry built-in meaning and keyboard behaviour. Use ARIA only when native HTML cannot do the job, and use it correctly, since wrong ARIA can make things worse.
Users need to know what happened and how to fix it: validation, login, payment errors, confirmations. Announce dynamic updates to assistive technology where appropriate and move focus to the error or summary.
Combine keyboard testing, screen reader testing, automated scans, contrast checks, mobile checks and manual review. Where possible, include people with disabilities. Automated tools cannot find every problem. Repeat tests after major design or code changes. Details follow in the testing section below.

Avoid these
| Mistake | How to avoid it |
|---|---|
| 1. Low-contrast text | Check every colour pair with a contrast tool before approving the design. |
| 2. Meaningful images without alt text | Add short, purposeful alt text; use empty alt for decoration. |
| 3. Placeholder text instead of labels | Add visible labels linked to each field. |
| 4. Menus that need a mouse | Build menus that open and close with the keyboard. |
| 5. Vague link labels | Name the destination: "View our corporate website service". |
| 6. Complicated navigation | Keep menus short and consistent. |
| 7. Ignoring keyboard focus | Keep a strong, visible focus style. |
| 8. Videos without captions | Add reviewed captions and a transcript. |
| 9. Colour as the only indicator | Add text or icons to colour cues. |
| 10. Adding ARIA incorrectly | Use native HTML first; use ARIA only when needed and test it. |
| 11. Trusting automated tools alone | Add manual keyboard and screen reader checks. |
| 12. Treating it as one-time work | Review after every major update and on a regular schedule. |
Testing
A good accessibility test mixes automated scans, which are quick and find common code problems, with manual testing, which finds problems in real use. Passing an automated scan does not prove full accessibility or WCAG compliance.
By business type
Accessibility and SEO
Some accessible practices also help search engines understand a page: descriptive headings, meaningful link text, image alt text, semantic HTML, readable content, clear navigation and mobile usability.
They are still different disciplines with different goals. Accessibility does not automatically improve rankings or guarantee traffic. For the search side, read why a website needs separate pages for each service.
Fixing barriers during development is usually easier than retrofitting a live site.
FAQs
Conclusion
Website accessibility makes a business website easier for more people to use. Contrast, alt text, keyboard access, clear headings, labelled forms, captions, simple navigation and semantic code are the foundation of an inclusive business website.
Treat these essential design practices as an ongoing part of development and maintenance, not a one-time task. Test after changes, and seek qualified advice on any legal requirements that apply to you. Related reading: AI website launch readiness checklist.
