Built for screen readers, parsed by search engines and AI alike. Ảnh hưởng đến: SEO + AIO
One structure, three audiences
Alt text, labeled forms, a declared language and real link names make a site usable with assistive technology, and the same explicit structure is exactly what search crawlers and AI assistants parse. Accessibility work is machine-readability work.
It's also increasingly a legal expectation in many markets, and an audience you're otherwise turning away.
What this site measures
The machine-checkable subset: a lang attribute on the page, alt text coverage on images, labels on visible form fields, and links that have an accessible name. Color contrast and keyboard operation need a manual or in-browser audit; the review says so rather than guessing.
How to improve
- Describe informative images in alt text; use empty alt for pure decoration.
- Give every form field a label (or aria-label) that survives placeholder text.
- Never ship icon-only links without an aria-label.
- Declare <html lang="…"> so screen readers pick the right voice.
- Run a free automated audit (axe, WAVE, Lighthouse) and fix what it finds.
Common mistakes
alt="image123.jpg". Placeholder text used instead of labels, which disappears the moment someone types. Click-here links that read as 'click here, click here, click here' to a screen reader.
