What is Web Accessibility?

Web accessibility is about designing and developing websites that can be used by all people, regardless of their physical, sensory, or cognitive abilities. The Web Content Accessibility Guidelines (WCAG) 2.1, published by the W3C, define international accessibility criteria organized into three levels: A, AA, and AAA. Beyond legal compliance, accessibility improves the experience for all users: an accessible site is better structured, more navigable, and more performant. TeckBlaze uses axe-core, the most recognized accessibility audit engine in the industry, to analyze each page of your site against over 80 WCAG rules. Each detected violation is classified by impact (critical, serious, moderate, or minor) and accompanied by a technical description, the affected HTML element, and a recommended fix. Our tool detects color contrast issues, images without alt text, forms without labels, broken keyboard navigation, and many other accessibility barriers.

What We Check

• Text/background color contrast (WCAG AA and AAA ratios)
• Alt text on all images and graphic elements
• Labels and associations for all form fields
• Full keyboard navigation (visible focus, tab order)
• ARIA roles and semantic attributes
• Heading structure (logical H1-H6 hierarchy)
• Links: descriptive text, no generic links (click here)
• Data tables: headers, captions, and associations
• Multimedia content: captions and transcriptions
• Touch target size (minimum 44x44 pixels)
• Respectful animations (prefers-reduced-motion)
• Page language declared in the lang attribute

How It Works

TeckBlaze integrates axe-core into its crawl process. For each visited page, our engine runs a complete accessibility analysis in a real browser (Chromium via Playwright). This allows detecting not only issues in static HTML but also those related to dynamic JavaScript, interactive components, and client-side rendering. Results are aggregated into a unified dashboard that sorts violations by type, severity, and frequency. You can see exactly which pages are affected, which HTML element causes the issue, and how to fix it. The report also includes an overall accessibility score and a comparison with your industry benchmarks.

Why It Matters

Web accessibility is not just a legal obligation — it is an ethical duty and a business advantage. Over 15% of the world's population lives with a disability. By making your site accessible, you expand your audience, improve your brand image, and avoid legal risks. Moreover, Google values accessible sites: a clear semantic structure, well-written alt attributes, and smooth navigation are positive ranking signals. Accessibility is also correlated with better performance and a superior user experience for all visitors.
