Website accessibility means making sure people with disabilities, including people who use screen readers, keyboards or magnification, can use your website. For small businesses, the practical benchmark is the Web Content Accessibility Guidelines (WCAG) at level AA. Accessible websites reach more customers, are easier for everyone to use and reduce the risk of accessibility complaints.
This article is general information, not legal advice. Speak with an attorney about your specific obligations.
What are WCAG and the ADA?
WCAG is a set of technical guidelines published by the World Wide Web Consortium (W3C). Versions 2.1 and 2.2 are widely used, and level AA is the most common target. The Americans with Disabilities Act (ADA) is a civil rights law. Website accessibility lawsuits against businesses are common in the United States, and WCAG AA is the standard most often referenced when evaluating whether a site is accessible.
Why accessibility is good business
More customers: people with disabilities, and older adults, are a large and loyal customer group.
Better usability for everyone: clear structure, readable text and simple forms help all visitors.
SEO benefits: descriptive headings, alt text and clean HTML also help search engines and AI tools understand your content.
Reduced risk: fixing common issues lowers the chance of complaints.
The most common accessibility issues to fix first
1. Missing alt text on images
Meaningful images need short descriptions so screen reader users understand them. Decorative images should have empty alt text so they are skipped.
2. Low color contrast
Light gray text on white backgrounds is hard to read. WCAG AA calls for a contrast ratio of at least 4.5:1 for normal body text.
3. Forms without labels
Every form field needs a visible, properly connected label. Error messages should explain what went wrong and how to fix it.
4. Keyboard navigation problems
Everything should work using only a keyboard, including menus, forms and pop-ups, with a visible focus indicator.
5. Poor heading structure
Use one main heading per page and logical subheadings. Screen reader users often navigate by headings.
6. Vague link text
Links like "click here" or "read more" do not make sense out of context. Describe the destination instead.
7. Videos without captions
Add captions to videos and avoid autoplaying media with sound.
8. Inaccessible PDFs and menus
Restaurant menus and documents posted only as image-based PDFs are often unreadable to screen readers. Publish key information as regular web content.
Are accessibility overlays enough?
Automated overlay widgets promise instant compliance, but they generally cannot fix underlying problems in your code and content, and many accessibility experts and users criticize them. Fixing issues in the website itself is the more reliable approach.

Frequently asked questions
Does my small business website need to be accessible?
Making your site accessible is strongly recommended. Many businesses that serve the public have faced accessibility claims, and accessible design benefits all your visitors. Consult an attorney for advice on your situation.
What level of WCAG should I aim for?
WCAG 2.1 or 2.2 level AA is the most widely used target for business websites.
Can automated tools find every accessibility issue?
No. Automated tools catch many common problems, but manual testing with a keyboard and screen reader is needed for a complete review.
