Markdown is the authoring layer. HTML is the delivery signal layer.
Markdown can improve editor efficiency and reduce token load in AI workflows, but HTML remains the reliable standard for SEO signals and consistent crawling.
For multilingual and global sites, focus on end-to-end signaling (semantic markup, structured data, and stable translations) rather than relying on file format alone.
Deploy a pragmatic mix: use Markdown for authoring and workflows where appropriate, but ensure clean HTML delivery with accessibility and multilingual signals for AI agents and humans.
Use Markdown for cleaner authoring, then ship semantic HTML with metadata, schema, accessibility, multilingual routing, and an llms.txt roadmap for AI-readable discovery.
