Heading Hierarchy Checker maps every heading tag on your page and validates it against correct structural rules.
A proper H1–H6 hierarchy signals content organization to search engines, improves accessibility for screen readers, and helps users scan your page efficiently.
This tool catches the most common heading mistakes — missing H1s, multiple H1s, skipped levels, and decorative misuse of heading tags — and presents them in a clear visual outline so fixes are obvious and fast.
An essential check before any page goes live.
