Sobre Heading Analyzer

Paste your HTML and see the complete heading hierarchy (H1-H6). Identify missing headings, skipped levels, duplicate H1 tags, and other structural issues that affect SEO and accessibility.

Como funciona

The tool parses HTML to extract all heading tags (h1-h6) and builds a hierarchical tree. It checks for common issues like missing H1, skipped levels (e.g., H2→H4), and multiple H1 tags.
