# Accessibility

In plain words

Accessibility refers to designing and building websites so people with visual, auditory, motor, or cognitive disabilities can use them, typically measured against the Web Content Accessibility Guidelines (WCAG). Accessible markup, like proper heading structure and alt text, also helps search engines and AI models parse a page correctly, making accessibility a shared foundation for usability, SEO, and AEO.

Example

Every button on a pricing page can be reached with the Tab key, shows a visible focus ring and has text that passes WCAG AA contrast against its background.

    ## How Do I Future-Proof My Website for AI Search and AI Agents?

    Build clean, well-structured content that directly answers real questions, keep your technical foundation fast and crawlable, and make sure your data is organized in a way machines — not just humans — can parse, including proper schema markup and clear page structure. AI agents browsing on a user's behalf and AI search tools both rely on the same underlying signals: clarity, structure, and accessibility. A site built well for AEO today is largely the same site that's ready for AI agents acting on visitors' behalf tomorrow.

    ## How Do I Optimize My Website for Search Engines?

    Start with clean technical SEO — fast load times, proper heading structure, mobile responsiveness — then build content around what your actual customers are searching for. Most sites over-invest in keywords and under-invest in structure. Google needs to crawl and understand your site before content quality even matters. Fix the technical foundation first, then focus content on answering real customer questions clearly.
