A plain-language orientation to ADA web accessibility for small business owners who are encountering this subject for the first time.

You Probably Got Here One of Three Ways

Either someone mentioned ADA website compliance in a conversation and you wanted to understand what they meant. Or you received a letter or email about your website's accessibility. Or you came across this topic while reading about small business legal risks and wanted to understand it better.

All three are reasonable paths to this page. The good news: you don't need to understand everything at once. This page is designed to give you a grounded starting point.

Key Terms, Defined Simply

ADA
The Americans with Disabilities Act. A federal civil rights law enacted in 1990 that prohibits discrimination against people with disabilities in employment, public services, and places of public accommodation. Title III covers businesses open to the public.
WCAG
Web Content Accessibility Guidelines. A technical standard published by the World Wide Web Consortium (W3C) that describes how to make web content accessible to people with disabilities. WCAG 2.1 Level AA is the version most referenced in legal and regulatory contexts in the US.
Title III
The section of the ADA that applies to places of public accommodation — businesses that serve the public. Courts have interpreted this to include websites in various circumstances, though the exact scope remains contested in some jurisdictions.
Screen Reader
Software that reads the content of a screen aloud, used by people who are blind or have low vision. Common screen readers include JAWS (Windows), NVDA (Windows, free), and VoiceOver (built into Apple devices). Accessibility testing often involves checking how a site behaves with a screen reader.
Conformance Level
WCAG organizes requirements into three levels: A (minimum), AA (intermediate), and AAA (enhanced). Level AA is the standard referenced in most legal and regulatory contexts. Achieving AAA on a general commercial website is often impractical.
Overlay Widget
A third-party JavaScript tool that adds a floating accessibility button to a website. When clicked, it opens a panel with user-preference controls. These tools are marketed as compliance solutions, but their actual effect on accessibility is disputed.
Alt Text
Alternative text is a written description of an image, stored in the image's HTML "alt" attribute. Screen readers read this text aloud. Without it, a screen reader user has no way to know what an image shows.
Contrast Ratio
A measure of the difference in luminance between two colors — typically text and its background. WCAG requires a ratio of at least 4.5:1 for normal text at Level AA. Higher ratios are easier to read for people with low vision or color blindness.

A Suggested Reading Path

If you're starting from scratch, here's a sequence that builds understanding progressively:

Understand the Standard

Read the WCAG 2.1 section on our What We Cover page. It explains the four principles and the specific criteria most relevant to small business websites. You don't need to memorize the criteria — you need to understand the categories of issues they address.

WCAG 2.1 Explained

Run a Free Audit on Your Site

Install the WAVE browser extension and run it on your homepage. Don't try to fix everything at once — just look at what comes up. The audit gives you a concrete picture of where your site stands right now.

Audit Guide

Address the Most Common Issues

Review the common violations section and cross-reference with what your audit found. Start with the issues that appear in both places — those are your highest-priority items. Many can be fixed in your CMS without developer help.

Common Violations

Understand the Legal Context

Read the legal landscape section to understand what courts have decided, what the DOJ has said, and what demand letters typically look like. This gives you factual context — not legal advice — for understanding your situation.

Legal Landscape

Common Misconceptions

Common Belief

"My website is small, so I don't need to worry about this."

Reality

ADA Title III doesn't have a size threshold for businesses. Demand letters have been sent to very small businesses. Whether that creates a legal obligation that applies to you specifically is a question for an attorney — but size alone is not a safe harbor.

Common Belief

"I installed an accessibility widget, so I'm covered."

Reality

Courts have not accepted overlay widget installation as a compliance defense. Plaintiffs have successfully argued that overlays did not remove the barriers they encountered. An overlay may provide some user-preference features, but it is not a substitute for addressing underlying issues.

Common Belief

"Making my site accessible requires a complete rebuild."

Reality

Many of the most common accessibility issues — missing alt text, poor color contrast, unlabeled form fields, non-descriptive link text — can be fixed directly in a content management system without touching code. A complete rebuild is rarely the starting point.

Common Belief

"There's a certification I can get that proves compliance."

Reality

No official government certification for ADA website compliance exists. Third-party auditors can provide accessibility audit reports, but these are professional assessments — not legal certifications. Compliance is ultimately determined by courts, not by certificates.
