What is Semantic HTML?
Using main, nav, header, article, and proper headings so assistive tech and parsers understand page structure. The foundation of both accessibility and machine readability.

Accessibility Checker
Automated WCAG scanning (contrast, labels, alt text, empty controls) as an audit baseline. Machine checks catch the common failures; manual review covers what tools cannot detect.
Machine-Readable Content
Content structured so parsers extract it reliably: semantic HTML, one H1, real lists and tables, descriptive link text, alt text, and schema that mirrors visible content.
Heading Hierarchy
The nested H1→H2→H3 outline of a page. A clean hierarchy lets readers scan and lets parsers chunk sections accurately for retrieval and snippets.
One-Click Deployment
Publishing a site to production hosting without manual configuration. BYOB deploys to an edge network with rollback to known commits when a release misbehaves.
Custom Domain
Your own address (you.com) instead of a builder subdomain, with automatic SSL. The trust baseline for anything commercial: subdomains convert worse and rank no better.
Visual Editing
Clicking page elements in a live preview and asking the AI to refine text, spacing, or layout. It keeps non-developers in flow while the underlying code stays standard and editable.
