Why ADA testing matters
ADA Title III applies to private businesses, and courts consistently use WCAG as the yardstick for determining what an accessible website looks like. With 5,000+ lawsuits filed in 2025 and settlements typically running $25k–$50k plus mandatory remediation, the question is not whether to test — it's whether you test before or after the demand letter arrives. Our ADA testing covers all WCAG 2.2 AA success criteria with manual and automated review, giving you a complete picture of your exposure before a plaintiff's firm does.
- All WCAG 2.2 AA success criteria
- Manual screen reader and keyboard testing
- Colour contrast and visual accessibility
- Forms, error messages, and interactive components
- Third-party embeds and media accessibility
- Prioritized remediation roadmap

Frequently asked questions
Common questions about ada compliance services.
US courts have consistently held that websites of places of public accommodation fall under ADA Title III. There is no fixed deadline for private businesses — the obligation is always active, enforced through lawsuits. If the public can use your site to buy from you or book with you, you are in scope.
WCAG 2.2 Level AA — the current standard cited by courts and referenced in most ADA settlements. Meeting 2.2 also satisfies 2.1 and 2.0.
A demand letter from a plaintiff's firm cites specific WCAG failures on your site and demands remediation and compensation. First-letter settlements typically run $25,000–$50,000 plus mandatory remediation. Zylyn's test identifies and prioritises those exact failure points before a plaintiff does.
Automated scanners catch 30–40% of WCAG failures. The rest require human judgment. Our reviewers use screen readers, keyboard-only navigation, and assistive technology to find what machines miss — the gaps that generate demand letters.
