Accessibility Practices for SEO

Accessible sites often rank better, cost less to maintain, and reach broader audiences. It’s both ethical and an SEO factor. Key practices:

Optimize title tags: Screen readers announce titles first—describe the page clearly.
Descriptive URL slugs: Short, readable, accurate; easier for users and screen readers.
Alt text for images: Explain the image for accessibility and image search ranking.
Proper heading structure: H1/H2/H3 hierarchy helps navigation via screen readers.
Limit intrusive interstitials: Avoid full-page popups/auto-play noise that overload users.
Screen-reader friendly layout: Prevent CLS; reserve space for dynamic content/media.
Clear, readable text: Good fonts/sizes; scaling shouldn’t break layout; ensure contrast, avoid red-green combos.
Keyboard navigation: Skip-to-content, Tab/arrow operable menus/controls, visible focus states.
Captions or transcripts for video: Support hearing-impaired/sensory-sensitive users.
Avoid flashing videos: Prevent photosensitive triggers.

Conclusion: Baking accessibility into SEO workflows boosts UX and search visibility together.
