Language & Structure
Verifies valid html lang attributes so text-to-speech engines use correct phonetic models.
Enter a domain to check accessibility hygiene across public pages.
Accessible HTML is fundamentally better understood by both assistive technology and neural crawlers.
Automated tools catch 30–40% of WCAG defects. Manual assistive tech testing is still required for full compliance.
We do not claim automated 100% scores guarantee ADA or legal compliance.
Without html lang, screen readers may read English text with a French or Turkish pronunciation engine, making it unintelligible.
Decorative images should have an empty alt='' attribute, not a missing alt attribute.
A div with an onclick handler cannot be navigated with Tab and activated with Enter/Space by keyboard users.
HTML&HTML prepares your website for visibility, citation eligibility and recommendation opportunity across AI search experiences. It shows measurable website-side blockers that can prevent discovery, understanding and source consideration.
robots.txt, sitemaps, canonicals, indexability and AI crawler access form the discovery foundation.
GEO, AEO, LLMO, entity graphs, schema and answer extractability reduce machine ambiguity.
RAG/retrieval, original information, E-E-A-T, freshness and evidence support source eligibility.
AAO, accessible journeys, intact links, measurable referrals and clear CTAs connect AI discovery to commercial action.
Recommendations, rankings, citations, traffic, customers and revenue are not guaranteed. HTML&HTML measures website-side technical and content blockers; it does not claim control over external AI systems.
