Accessible Components Checklist — WCAG Wins That Also Boost SEO
Semantics before ARIA
Native button, nav, main, and heading elements give keyboard support and screen-reader meaning free. The first rule of ARIA is to not need it — audit for div-buttons and div-headings before adding a single role attribute.
Focus is a feature
Visible focus rings (never outline: none without replacement), logical tab order, focus trapped in modals, and focus returned to triggers on close. Skip links let keyboard users bypass navigation — one line of markup, enormous daily impact.
Forms that explain themselves
Every input needs a programmatic label, errors announced via aria-describedby, and success confirmed in text (never color alone). Test the entire checkout with keyboard only; the failures you find are the ones losing you customers.
Why SEO cares
Google's accessibility signals overlap with ranking factors: semantic headings structure understanding, alt text feeds image search, and usable pages earn the engagement metrics that rankings follow. Accessibility is SEO with a conscience.
