Page Metadata

Handles the meta tags that don't get as much love as title and description but still matter for indexing and international sites. Checks hreflang for multilingual setups, meta robots directives, viewport and charset declarations, and flags missing metadata across pages. It reads project context files if they exist to understand your language and indexing goals before auditing. Honestly most useful if you're launching in multiple regions or need to audit why certain pages aren't indexing the way you expect. Part of kostja94's marketing skills collection, which covers the full SEO and paid media stack.
