ADA Website Compliance Checklist for Small Businesses (WCAG 2.2 AA)

The Department of Justice confirmed in 2022 that the ADA applies to business websites under Title III — meaning your website must be accessible to people with disabilities or you face legal risk. With demand letters costing $5,000–$25,000 to settle and full lawsuits averaging $75,000–$150,000, understanding your specific WCAG 2.2 AA compliance gaps is not optional for any business with an online presence.

What Is WCAG 2.2 AA and Why Does It Apply to Your Website?

WCAG (Web Content Accessibility Guidelines) 2.2 Level AA is the official accessibility standard published by the W3C and adopted by courts as the benchmark for ADA website compliance. The standard organizes requirements into four principles — Perceivable, Operable, Understandable, and Robust — and specifies 78 success criteria, of which Level AA requires compliance with 50. The DOJ finalized a rule in April 2024 making WCAG 2.1 AA explicitly required for state and local government websites, and federal courts routinely apply the same standard to private businesses under Title III.

For small businesses, WCAG 2.2 AA compliance is not a technology project — it is a legal risk management decision. A website that fails five or more WCAG AA criteria is statistically likely to receive a demand letter within 24 months based on current litigation volume data (UsableNet, 2024).

What Are the 7 Most Common ADA Website Violations?

Analysis of 4,600+ ADA website lawsuits filed in 2023 reveals that seven WCAG violations appear in over 70% of complaints (UsableNet, 2024). These are the first issues plaintiff attorneys check — and the first issues you should fix.

1. Missing image alt text (WCAG 1.1.1) — Images without text descriptions are inaccessible to screen reader users. Every meaningful image on your site needs an alt attribute that describes its content.
2. Insufficient color contrast (WCAG 1.4.3) — Text must have a contrast ratio of at least 4.5:1 against its background for normal text and 3:1 for large text. Light gray text on white backgrounds fails this test.
3. Keyboard traps (WCAG 2.1.2) — Users who navigate by keyboard (including those using assistive technology) must be able to move through all interactive elements. Modal dialogs that trap focus are a frequent violation.
4. Missing form labels (WCAG 3.3.2) — Every form input must have a visible, descriptive label. Placeholder text alone does not satisfy this requirement.
5. Non-descriptive link text (WCAG 2.4.4) — Links that say "click here" or "learn more" provide no context for screen reader users navigating by links. Link text must describe the destination.
6. No skip navigation (WCAG 2.4.1) — A "skip to main content" link must appear at the top of each page so keyboard users can bypass repetitive navigation menus.
7. Missing page language (WCAG 3.1.1) — The HTML lang attribute must declare the page language (e.g., lang="en") so screen readers apply correct pronunciation.

What Does an ADA Demand Letter Cost?

ADA demand letters typically demand $5,000–$25,000 in attorney fees and damages for website accessibility violations. Businesses that fight these letters in court face average legal costs of $75,000–$150,000 plus potential injunctions requiring immediate remediation (Seyfarth Shaw ADA Title III Update, 2024). The vast majority of cases — approximately 96% — settle out of court, but settlement still requires legal representation, remediation costs, and monitoring agreements.

The cost of prevention is substantially lower. A professional accessibility audit costs $500–$2,000 for most small business websites. Remediation of common violations costs $2,000–$8,000 depending on the website's complexity. Proactive compliance costs approximately 5–10% of the average settlement amount — making it the obvious financial choice.

Does WCAG Compliance Also Improve GEO Scores?

Yes — and significantly. WCAG compliance overlaps with GEO optimization in several critical areas. Properly structured HTML headings (required for accessibility) are the same heading hierarchy AI systems need to understand your content. Alt text on images provides textual content AI systems can index. Semantic HTML elements (nav, main, article, aside) that screen readers require are the same landmark elements AI systems use to identify page structure. A business that achieves WCAG 2.2 AA compliance simultaneously improves its GEO structure score by an average of 15–25 points based on SiteMarketing.ai audit data.
