Heading Outline Generator
Enter a URL or paste HTML to visualize the full H1-H6 outline and catch structural issues.
About this tool
This visualizes the full heading hierarchy as an indented outline and flags missing H1s, multiple H1s, skipped levels, and empty headings — a different view from the Heading Checker, which lists headings in a flat table. Use whichever view is more useful for your workflow.
