What is web accessibility and why is it important for my business?

Web accessibility ensures that websites are usable by everyone, including people with disabilities. For businesses, it's essential for legal compliance (ADA, Equality Act), expanding market reach to an estimated 16 percent of the global population, about 1.3 billion people, improving SEO rankings, and demonstrating social responsibility. Accessible sites also typically provide a better user experience for all visitors.

What are WCAG guidelines and which version should I follow?

WCAG (Web Content Accessibility Guidelines) are the international standards. WCAG 2.2 has been the current W3C Recommendation since October 2023. Most businesses should aim for WCAG 2.2 Level AA compliance, as it is the standard referenced by most legal frameworks and provides a robust level of accessibility without the strict constraints of Level AAA.

What are the most common web accessibility issues developers should fix?

The most frequent violations include low contrast text, missing alt text for images, empty links/buttons, missing form labels, and poor keyboard navigation. Fixing these five issues can resolve a significant portion of accessibility barriers. Our automated tools can help identify these instantly.

How do I implement WCAG 2.2 in my development workflow?

Start with semantic HTML5 (using , , correctly). Ensure all interactive elements are keyboard accessible with visible focus states. Use ARIA labels only when native HTML isn't sufficient. Integrate automated accessibility testing into your CI/CD pipeline and perform manual keyboard testing before every release.

What is the difference between WCAG Level A, AA, and AAA?

Level A is the minimum baseline (essential for some users to access content). Level AA is the global standard for legal compliance and general usability. Level AAA is the highest standard, ideal for specialized content but often not feasible for entire complex web applications. We recommend targeting Level AA.

How can I test my website for accessibility compliance?

Use a hybrid approach: 1) Automated scanning (like our URL Auditor) to catch ~40% of issues. 2) Manual keyboard testing (Tab through every page). 3) Screen reader testing (NVDA, VoiceOver). 4) Color contrast analysis. 5) User testing with people with disabilities for the most accurate feedback.

Are your accessibility tools free to use?

We offer a robust suite of free tools including the Contrast Checker, Heading Analyzer, and Color Palette Generator. We also offer premium AI-powered features for deep auditing, alt text generation, and remediation suggestions for professional teams.

How accurate are AI-powered accessibility tools?

AI tools are excellent for detecting programmatic errors and suggesting fixes (like alt text), but they cannot fully judge context or usability. Our tools use AI to speed up the process, but we always recommend human verification. Think of AI as a powerful assistant, not a replacement for human judgment.

What should I include in alt text for images?

Context is key. For informative images, describe the content and meaning. For functional images (icons in buttons), describe the action (e.g., 'Search', not 'Magnifying glass'). For decorative images, use an empty alt attribute (alt='') so screen readers ignore them.

How do I make my website keyboard accessible?

Ensure a logical tab order that follows the visual layout. Never trap the keyboard focus. Provide a clear, high-contrast visual focus indicator (outline) for all interactive elements. Ensure all custom widgets (modals, dropdowns) can be opened, navigated, and closed using only the keyboard.

What color contrast ratio do I need for compliance?

For WCAG 2.1/2.2 AA: Normal text needs 4.5:1. Large text (18pt+ or 14pt+ bold) needs 3:1. UI components and graphical objects also need 3:1. Use our Contrast Checker to verify your design tokens before implementation.

Do I need to make my mobile app accessible too?

Yes. Mobile accessibility is critical. Follow platform specifics (iOS/Android accessibility APIs) and WCAG principles. Ensure touch targets are large enough (44x44px minimum), support dynamic type (text resizing), and work with mobile screen readers (VoiceOver/TalkBack).

How much does a web accessibility audit cost?

Published market rates run roughly $1,500 to $5,500 for a small business site and $50,000 or more for large enterprise engagements, with per-page rates commonly $100 to $250. Our own fixed-price WCAG 2.2 AA audits are $950 for the Essential Audit (up to 5 page templates, 7-10 business days), $2,750 for the Product Audit, and $5,900 for the Complex Product Audit. The price is fixed before work begins rather than quoted hourly.

Who can audit my site for WCAG or European Accessibility Act compliance?

You can run free automated tools for a baseline, but they detect only about 40% of issues, so WCAG and EAA conformance requires manual testing by a qualified auditor. Accessibility.build is a founder-led practice run by Khushwant Parihar, who holds the IAAP CPACC certification and the DHS Trusted Tester credential, and offers fixed-price WCAG 2.2 AA audits from $950. Before committing, you can inspect a fully worked sample report at accessibility.build/sample-audit-report, built on a fictional product in the format every audit follows.

How much does PDF accessibility remediation cost?

We price PDF remediation per page, by document complexity rather than by flat rate. Simple text-led pages start at $3 per page, structured documents with tables and multi-column layouts are $7 per page, and complex pages with charts, forms, or scanned content are $12 per page. Every remediated file is tagged to PDF/UA and WCAG 2.2 AA and checked before delivery.
