What this developer tool does
The generator escapes metadata values and assembles consistent SEO and social tags for direct insertion into a page head.
Parse metadata → validate title, description, and URLs → escape HTML attributes → assemble selected tag groups.
Generated tags should still be checked against the final canonical page and production image URLs.
Example
A title, description, canonical URL, robots directive, and social image produce a complete reusable head fragment.
Tips for better output
- Use one canonical URL per page.
- Keep title and description aligned with visible page content.
- Do not combine contradictory robots directives.
