See your heading structure at a glance.

Extracts H1–H6 headings and detects skipped levels, duplicates, and missing tags. An essential tool for SEO audits and content QA.

Features

Lists all H1–H6 headings in DOM order, indented by level so you can see the structure at a glance.

Automatically flags skipped heading levels — like an H4 right after an H2 — so you can fix hierarchy issues fast.

Detects pages with zero H1s or multiple H1s — covering a fundamental SEO checkpoint.

Copy the heading structure as indented plain text — ready to paste into reports or feedback documents.
