Free Website Accessibility Audit: What It Can (and Can't) Tell You
You've heard about ADA lawsuits. You've read that your website might have accessibility issues. You're a small business owner, not a developer or a disability rights lawyer — and you want a straight answer: Is my website accessible or not?
A free website accessibility audit is the fastest way to start finding out. But before you run one, it helps to understand exactly what you're getting — and where the edges of automated testing lie. This guide will walk you through what free accessibility audits actually do, how to read your results, and what steps come next.
What Is a Website Accessibility Audit?
A website accessibility audit evaluates your site against established standards — most commonly the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA. This is the standard the U.S. Department of Justice has formally recognized as the benchmark for ADA website compliance.
WCAG 2.1 Level AA contains 50 success criteria covering everything from image descriptions (alt text) to keyboard navigation to color contrast ratios. An audit checks how well your website meets those criteria.
Audits come in two types:
- Automated audits: Software scans your web pages and checks for detectable issues. Fast, free or low-cost, and a great starting point.
- Manual audits: A human accessibility expert navigates your site using assistive technologies like screen readers and tests for issues automated tools can't detect. More thorough, but expensive and time-consuming.
For most small businesses, an automated audit is the right first step — and often all you need to prioritize your most important fixes.
What a Free Accessibility Audit Can Detect
Automated accessibility scanners check your page's HTML, CSS, and JavaScript for patterns that are known to cause accessibility barriers. Here's what they're good at catching:
Missing or Empty Alt Text
Images without alt text are invisible to screen reader users. Automated tools can reliably detect when an element has no alt attribute, or when the alt attribute is empty when it shouldn't be. This is one of the most common issues on small business websites — and one of the easiest to fix.
Color Contrast Problems
WCAG requires that text have a contrast ratio of at least 4.5:1 against its background (3:1 for large text). Automated tools can calculate this precisely from your CSS and flag any text that falls below the threshold. Low contrast text is hard to read for people with low vision and creates compliance issues even for users without disabilities.
Missing Form Labels
HTML forms need to associate each input field with a visible label using proper markup. When developers use placeholder text instead of real labels, or when labels aren't programmatically linked to their fields, screen readers can't tell users what information to enter. Automated tools catch this reliably.
Missing Page Titles
Every web page should have a descriptive element. This helps screen reader users understand where they are and helps everyone navigate between browser tabs. Automated scanners check this in seconds.
Language Declaration
Your HTML should declare the language of the page (). This allows screen readers to use the correct pronunciation rules. Easy to miss, easy to fix, and easy for scanners to detect.
Keyboard Focus Indicators
When users navigate a website using only the keyboard (many people with motor disabilities do this), they need visible focus indicators — the outline that shows which element is currently selected. CSS that removes these focus outlines is a common problem that automated tools can flag.
Duplicate ID Attributes
HTML IDs must be unique on a page. Duplicate IDs can break assistive technology behavior in unpredictable ways. Automated scanners catch these reliably.
Missing Skip Navigation Links
Long navigation menus force keyboard users to tab through every menu item to reach the main content. A "skip to main content" link is the standard solution. Automated tools can check for its presence.
What a Free Accessibility Audit Cannot Detect
Here's where you need to set realistic expectations. Automated tools — even the best ones — can only detect roughly 30 to 40 percent of WCAG issues. The rest require human judgment.
Whether Alt Text Is Meaningful
A scanner can tell you that an image has an alt attribute. It can't tell you if "IMG_2847.jpg" or "image" actually describes what's in the picture. Meaningful alt text requires a human to evaluate the context and content of each image.
Whether a Form Is Truly Usable
A scanner can check that labels exist. It can't navigate through your checkout process as a screen reader user and evaluate whether the experience is actually understandable and logical. User flows require human testing.
Complex Interactive Elements
Dropdown menus, date pickers, custom modals, accordions, and other JavaScript-powered components often have deep accessibility issues that only emerge during real interaction. Automated tools can check basic attributes but miss behavioral problems.
Reading Order and Logical Structure
Does your content make sense when read linearly by a screen reader, even if it looks fine visually? Does your heading structure (H1, H2, H3) reflect the actual hierarchy of your content? Scanners can check if headings exist; they can't evaluate whether the structure makes sense.
Cognitive Accessibility
Is your content written in plain language? Are error messages clear and helpful? Is there enough time to complete tasks? These are real accessibility barriers, but they require human evaluation.
PDFs and Documents
If you link to downloadable menus, brochures, application forms, or price lists, those documents need to be accessible too. Most automated web scanners don't audit linked files.
How to Use Your Free Audit Results
Getting a list of issues is just the beginning. Here's how to turn your audit report into action:
Step 1: Look at the Issue Count and Categories
Don't panic if the number is large. Many pages have dozens of issues that fall into just a few categories. Group similar issues together — fixing "missing alt text" as a pattern is faster than treating each image as a separate problem.
Step 2: Prioritize by Impact
Not all issues are equal. Focus first on barriers that prevent users from completing critical tasks:
- High priority: Issues that block navigation, form completion, or checkout
- Medium priority: Issues that create friction but don't completely block access
- Lower priority: Minor structural or metadata issues
Step 3: Share the Report with Your Developer
If you have a developer who manages your website, send them the audit report. Accessibility fixes are almost always code changes — changes to your HTML, CSS, or JavaScript. You need someone who can actually edit the site.
Step 4: Fix and Retest
After your developer makes changes, run another audit to verify the issues are resolved. New content and site updates can also introduce new issues, so consider making periodic accessibility checks part of your routine.
Step 5: Know When to Go Deeper
If your website has complex functionality — e-commerce, booking systems, member portals — or if you've received an ADA demand letter, a manual audit by an accessibility expert is worth the investment. Automated tools can't give you the confidence level you need in high-stakes situations.
Why Small Businesses Should Start with Automated Scanning
For most small businesses, a full manual audit isn't the right first step. Here's why automated scanning makes sense as your entry point:
It's fast. CheckMyADA can scan your website in minutes. You get immediate visibility into your most common issues.
It's affordable. A free or low-cost automated scan gives you real information before you commit to developer time or professional services.
It creates a baseline. Once you know your starting point, you can measure progress as you make improvements.
It prioritizes your efforts. A 50-issue report might sound overwhelming. But when you see that 35 of those issues are missing alt text on product images, the fix becomes clear and manageable.
It's honest. A good automated scanner tells you what it found and is clear about what it didn't check. It doesn't claim to make you compliant — it gives you the information you need to get there.
What CheckMyADA Does (and Doesn't Promise)

What we do:
- Scan your pages against WCAG 2.1 Level AA criteria
- Return a clear report organized by issue type and severity
- Explain each issue in plain language with specific guidance for your developer

Frequently Asked Questions
How long does a free accessibility audit take?
CheckMyADA scans a typical small business website in under 2 minutes. Larger sites with many pages may take longer.
Do I need to give you access to my website?
No. Our scanner works on any publicly accessible URL. Just enter your web address and we'll do the rest.
What if my website is built on WordPress, Shopify, or Squarespace?
CheckMyADA works with any website platform. Platform-specific issues — like themes that add inaccessible elements — will show up in your results.
Will fixing the issues found in the audit make me fully compliant?
Fixing the detected issues will improve your accessibility and reduce your risk significantly. But remember: automated tools catch 30–40% of potential issues. For high-stakes situations, complement the automated audit with professional manual testing.
Is a free audit enough if I've received an ADA demand letter?
No. If you've received a legal demand, consult an attorney and engage an accessibility professional for a full manual audit. A free scan is a starting point for proactive businesses, not a legal defense strategy.
The Bottom Line
A free website accessibility audit is the smartest first step any small business can take. It gives you real information — specific issues, specific locations, specific guidance — so you can actually improve your website instead of just hoping you're covered.
The goal isn't a compliance certificate. The goal is a website that works for everyone, including the roughly 26% of American adults who live with some form of disability.
