Website Accessibility Basics for Small Businesses

Web accessibility means designing and building a website so that people with a wide range of abilities and circumstances can use it. That includes people who are blind or have low vision, are deaf or hard of hearing, have limited movement, or have cognitive differences, as well as anyone with a temporary or situational limitation, like a broken arm or bright sunlight on a screen.

Why it matters

It is the right thing to do. A website is often how people access services, information, and shopping.

It helps everyone. Clear structure, readable text, and keyboard support make sites easier for all visitors.

It overlaps with SEO. Headings, alt text, and well-organized content help both assistive technology and search engines.

There may be legal expectations. Many countries have laws or guidance relating to digital accessibility, which vary by region and sector. Check what applies to you. This article is general information, not legal advice.

The WCAG guidelines

The most widely used standard is the Web Content Accessibility Guidelines, or WCAG, published by the W3C. They are organized around four principles. Content should be:

Perceivable: people can see, hear, or otherwise sense it.
Operable: people can navigate and use it, including by keyboard.
Understandable: content and interface behavior are clear.
Robust: it works with different browsers and assistive technologies.

Most organizations aim for WCAG 2.1 or 2.2 Level AA.

First steps for small sites

Use meaningful headings in order. See using headings.
Add alt text to meaningful images. See alt text best practices.
Check color contrast. See color contrast.
Make sure everything works with a keyboard, and focus is visible. See keyboard navigation and focus.
Label form fields properly, and make errors clear. See accessible forms.
Use readable text sizes and spacing. See readable text.
Make touch targets large enough. See touch target sizes.
Write clear link text. "Read our pricing guide" is better than "click here."
Provide captions or transcripts for audio and video.
Do not rely on color alone to convey information.
Allow zoom and make layouts responsive.

Test it

Try navigating your site using only the keyboard. Zoom the page to 200 percent. Run an automated checker, but remember that tools catch only a portion of issues, so manual checks and, ideally, testing with disabled users are essential. A screen reader such as the one built into your operating system can reveal problems quickly.

Beware of overlay shortcuts

Accessibility "overlay" widgets that promise instant compliance with one line of code are widely criticized by accessibility professionals. Fix the underlying design and code instead.

Include accessibility from the start

Fixing issues later costs more than designing well from the beginning. Mention accessibility in your design brief.

Add an accessibility statement

Optionally, publish a short page describing your commitment and how to report problems.

The bottom line

Accessibility is a practice, not a one-time task. Start with the basics above, test regularly, and keep improving.
