Accessibility gets filed under "compliance", which is a shame, because the things that make a site usable for someone with a screen reader are the same things that make it better for everyone — and for search engines.
Why it overlaps with SEO
- Proper headings and structure help both screen readers and crawlers.
- Descriptive alt text helps blind users and image search.
- Good contrast and clear labels reduce confusion and bounce.
- Fast, keyboard-friendly pages are simply better pages.
Build it in from the start and accessibility costs almost nothing. Bolt it on later and it costs a redesign. Clear, considerate design is the goal — accessibility is just what we call it when we take that seriously.
