Website Accessibility for Small Businesses: A Practical WCAG Checklist

Website accessibility for small businesses means people can perceive, understand, navigate and use your site across different abilities, devices and situations. It helps people with visual, hearing, motor and cognitive disabilities, and it often improves usability for everyone using a small screen, slow connection or temporary injury.

The W3C Web Content Accessibility Guidelines 2.2 provide testable criteria organized around four principles: content should be perceivable, operable, understandable and robust. The checklist below is a practical starting point, not a legal opinion or a substitute for testing with people with disabilities.

Make structure understandable

• Use one descriptive page title and a logical heading hierarchy.
• Write link text that explains the destination instead of “click here.”
• Use real lists, buttons and form controls rather than styled text that only looks interactive.
• Identify the page language so assistive technology can pronounce content correctly.

Support keyboard and focus navigation

Unplug the mouse and move through the page with Tab, Shift+Tab, Enter, Space and arrow keys. Every interactive control should be reachable, usable and visibly focused. The order should follow the visual and logical flow.

Avoid keyboard traps, unexpected pop-ups and menus that close before a keyboard user can choose an item. Provide a “skip to content” link on pages with repeated navigation.

Improve text, colour and images

Use readable type sizes and adequate line spacing. Do not communicate status by colour alone. Check text and interface contrast with a reliable contrast tool, including button states and form errors.

Give informative images concise alternative text that communicates their purpose. Decorative images should have empty alt text so screen readers can ignore them. Charts need a text summary or data table; screenshots containing essential text need that text in the page.

Make forms forgiving

• Associate a visible label with every field.
• Explain required formats before submission.
• Identify errors in text and connect each message to the affected field.
• Preserve valid answers when one field fails.
• Provide review and correction for important financial or legal submissions.

Provide accessible media and interactions

Caption prerecorded video with accurate dialogue and meaningful sounds. Provide transcripts for audio content, and audio description when important visual information is not in the soundtrack. Avoid autoplay with sound and give users a way to pause moving or updating content.

Make touch targets easy to activate and avoid interactions that depend on complex gestures. Test at 200% zoom and in both portrait and landscape orientations.

Use automated tools correctly

Automated scans can find missing labels, some contrast failures and invalid markup, but they cannot judge whether alt text is useful, headings make sense or the buying journey works with a keyboard. Combine scans with manual keyboard testing, screen-reader checks and real-user feedback.

Performance and accessibility reinforce each other when pages are simple and resilient. Pair this review with our Core Web Vitals guide.

A practical improvement order

1. Fix blockers in navigation, forms and checkout.
2. Repair templates so improvements reach many pages.
3. Correct high-traffic content and documents.
4. Add accessibility checks to publishing and release processes.
5. Publish an accessibility contact method and respond to reported barriers.

Frequently asked questions

Does using an accessibility overlay make a site compliant?

No tool can automatically correct every content, design and code issue. Sustainable accessibility requires accessible templates, content practices and human testing.

What conformance target should a business use?

WCAG 2.2 Level AA is a common practical target, but applicable requirements depend on your location, sector and contracts. Get qualified legal advice for compliance obligations.

How often should we test?

Test critical journeys after significant changes, scan regularly and include accessibility in every design and content review.
