Top Website Accessibility Tips to Meet WCAG Standards

Top Website Accessibility Tips to Meet WCAG Standards

7/21/2025

1) Use Semantic HTML for Structure and Meaning

Help assistive technologies interpret your content with proper headings (h1–h6), lists, and elements like nav, main, header, and footer. Use HTML for structure—not just visual styling.

Tip: Don’t skip heading levels, and ensure each page has a single, descriptive <h1>.

2) Provide Text Alternatives for Non-Text Content

Images and icons should include descriptive alt text that communicates their purpose or information.

Tip: Avoid “image of.” Instead, describe function: e.g., Download your contrast results.

Example of alt text that conveys purpose and outcome.

3) Ensure Sufficient Color Contrast

Low contrast is one of the most common barriers. WCAG recommends a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text.

Tip: Test early with a contrast checker before you lock in your palette.

4) Make All Functionality Accessible via Keyboard

Interactive elements must be operable with a keyboard alone (Tab, Shift+Tab, Enter, Space, Arrow keys). Ensure visible focus styles and logical tab order.

Tip: Unplug your mouse and try to navigate your site end-to-end.

Replace vague “Click here” with meaningful link text that explains destination or action. This helps screen reader users and improves SEO.

Tip: Example: Download the Accessibility Checklist.

6) Provide Captions and Transcripts for Multimedia

Caption videos and offer transcripts for audio. Accessibility improves comprehension for everyone—and can boost search visibility.

Tip: Use closed captions (CC) for video and include downloadable transcripts.

7) Test with Real Users and Accessibility Tools

Automated tools catch common issues, but real users reveal gaps in context and interaction.

  • Automated scanners (e.g., axe, WAVE) for quick checks
  • Manual keyboard and screen reader testing (NVDA, VoiceOver)
  • Feedback from users with disabilities for real-world validation
Tip: Combine automated, manual, and user testing for the best coverage.

Why Accessibility Matters for Your Business

Accessible sites reach more people, reduce legal risk around ADA compliant websites, and reflect a brand that values inclusion. Following WCAG guidelines also tends to improve overall UX, speed, and SEO.
