Launch Free Scanner →Why You Need an ADA Compliance Checker
The ADA requires businesses that serve the public to make their websites accessible to people with disabilities. There is no grace period, no minimum business size, and no exemption for websites built on popular platforms. If your site is inaccessible, you are exposed to lawsuits, demand letters, and lost customers today.
The latest accessibility statistics show that 96 percent of the top one million websites have detectable WCAG failures. That means the overwhelming majority of businesses have at least some legal exposure. An ADA compliance checker is the fastest way to find out where your site stands and what needs to be fixed.
How the ADA Scanner Free Checker Works
ADA Scanner uses automated testing engines to crawl your page and evaluate it against WCAG 2.1 Level A and Level AA success criteria. Here is what happens when you run a scan:
- 1Enter your URL. Navigate to the scanner page and type or paste your website address. No account creation or login required.
- 2The scanner loads your page. ADA Scanner renders your page in a real browser environment, including JavaScript-rendered content. This catches issues that basic HTML validators miss.
- 3Automated checks run against WCAG 2.1. The engine tests for dozens of specific accessibility criteria: color contrast ratios, alt text presence, form label associations, heading structure, keyboard accessibility, ARIA attribute validity, and more.
- 4Results are organized by severity. Each issue is categorized as critical, serious, moderate, or minor. Critical issues are those most likely to trigger lawsuits or completely block access for users with disabilities.
- 5You get actionable fix guidance. Every detected issue includes the specific WCAG success criterion it violates, the HTML element involved, and clear instructions on how to fix it. No accessibility expertise required to understand the results.
What the Free ADA Scan Checks For
The free scan evaluates your page against the full set of automatically testable WCAG 2.1 Level A and Level AA criteria. Key areas include:
Color Contrast
Verifies that text and interactive elements meet the 4.5:1 minimum contrast ratio for normal text and 3:1 for large text.
Image Alt Text
Detects images missing alt attributes and flags images with suspicious alt text like filenames or placeholder text.
Form Labels
Checks that every form input has a programmatically associated label that screen readers can announce.
Heading Structure
Validates that headings follow a logical hierarchy and no levels are skipped, enabling screen reader navigation.
Keyboard Access
Tests that interactive elements are reachable and operable with keyboard-only navigation.
ARIA Validity
Ensures ARIA roles, states, and properties are used correctly and do not create misleading information for assistive technology.
Link Text
Identifies empty links, links with generic text, and linked images without alt attributes.
Document Language
Confirms the HTML element has a valid lang attribute so screen readers use the correct speech engine.
How to Read Your Accessibility Report
Your scan results are organized to help you take action immediately. Here is how to interpret each section:
Overall Score
Your accessibility score provides a high-level snapshot. A higher score indicates fewer detectable violations relative to the number of elements tested. Use it as a benchmark to track improvement over time, not as an absolute measure of compliance.
Issue Severity Levels
Critical and serious issues should be addressed first. These are the violations that completely prevent access for certain users and are most frequently cited in ADA lawsuits. Issues like missing form labels and inaccessible menus typically fall into the critical category.
Element-Level Detail
Each issue links to the specific HTML element on your page. You can see exactly which image is missing alt text, which form field lacks a label, or which text block fails contrast. This element-level precision means your developer or webmaster can go straight to the relevant code and fix it without guessing.
WCAG Reference
Every issue is mapped to its corresponding WCAG 2.1 success criterion. This documentation is valuable if you need to communicate with developers, report to compliance teams, or demonstrate due diligence in the event of a legal inquiry.
What Automated Scanning Cannot Catch
Automated tools are essential but not sufficient for full compliance. They detect roughly 30 to 50 percent of WCAG violations. Issues that require human judgment include:
- Whether alt text accurately describes the image content, not just whether it exists.
- Whether keyboard focus order follows a logical, intuitive sequence through the page.
- Whether video captions are accurate and properly synchronized.
- Whether error messages are clear enough for users to correct their input.
- Whether custom interactive components communicate their state correctly to assistive technology.
Automated scanning gives you the critical first layer of defense. For complete coverage, pair it with periodic manual audits. Healthcare providers should pay special attention to patient portal accessibility requirements that go beyond what automated tools can verify.
Step-by-Step: Scan Your Site with ADA Scanner
Step 1: Go to the Scanner
Open adascanner.org/scanner in any browser. The tool works on desktop and mobile.
Step 2: Enter Your Website URL
Type or paste the full URL of the page you want to scan. Start with your homepage, then scan critical pages like your contact form, checkout flow, or online menu.
Step 3: Review Your Results
Within 60 seconds, you receive a complete report. Review the summary score, then drill into critical and serious issues first. Each issue shows the exact element, the WCAG criterion violated, and a recommended fix.
Step 4: Fix Priority Issues
Share the report with your developer or web team. The element-level detail means they can fix issues directly without additional investigation. Most critical violations take minutes to resolve once identified.
Step 5: Re-Scan and Monitor
After fixes are deployed, run another scan to verify. For ongoing protection, set up scheduled monitoring to catch regressions automatically.

Frequently Asked Questions
Is the ADA compliance checker really free?
Yes. The free scan checks your page for WCAG 2.1 violations with no signup and no credit card. You receive a full report with specific issues, severity levels, and fix guidance. Paid plans add multi-page scanning, scheduled monitoring, and team features.
What WCAG standards does the checker test against?
ADA Scanner tests against WCAG 2.1 Level A and Level AA, the standard referenced by the DOJ in ADA enforcement. This covers contrast, keyboard access, alt text, form labels, heading structure, and ARIA usage.
Can an automated tool find all accessibility issues?
Automated tools catch 30 to 50 percent of WCAG violations, including the most common and most sued-over issues. Some criteria require human judgment. Start with automated scanning, then supplement with manual testing for comprehensive coverage.
How often should I scan my website?
Scan after every significant update. For sites with regular content changes, weekly or monthly automated monitoring catches regressions before they become legal exposure. Browse the blog for more guidance on maintaining compliance.
Does passing a scan mean my site is ADA compliant?
Passing an automated scan is a strong positive indicator but not a complete guarantee. It means your site is free of the most common detectable violations. For full compliance, combine scanning with manual audits and real-user testing.
