Paste a page's HTML source below to instantly extract its full H1-H6 heading structure and spot hierarchy issues.
Headings (H1 through H6) create the outline of a page for both readers and search engines. A clear, logical hierarchy — one H1, followed by properly nested H2s and H3s — helps search engines understand what a page is about and helps screen readers navigate content for users with visual impairments.
Common issues include multiple H1 tags (which dilute topical focus), skipped heading levels (which break the logical outline), and headings used purely for visual styling rather than structure.
Most current SEO guidance recommends exactly one H1 per page that clearly states the main topic, with H2s and H3s used to structure supporting sections.
It's not a strict ranking penalty, but it breaks the logical outline of the page, which can hurt accessibility for screen reader users and make the content harder for search engines to parse cleanly.
It helps reinforce topical relevance when it fits naturally, but headings should primarily describe the content accurately — forcing keywords into every heading can hurt readability.
The visible page doesn't reveal which text is actually wrapped in heading tags versus just styled to look large — pasting the HTML source gives an accurate structural read.
