Analyze the H1–H6 heading structure of any webpage for SEO best practices.
Practical guide
Heading tags give readers, assistive technologies, search systems, and content extraction tools a navigable outline of a page. This analyzer fetches a public URL, lists its H1 through H6 elements in document order, and highlights the number of H1 headings. The result helps reveal missing section labels, skipped levels, empty headings, and headings used only for visual styling.
A useful review asks whether the main heading identifies the page, whether each H2 introduces a distinct section, and whether H3 headings belong to the H2 above them. Counts alone cannot judge clarity. Pages behind authentication, pages that block the fetch service, and content added only after complex client-side interactions may not be represented completely.
Spot sections that are visually obvious but have no semantic heading, or headings that do not describe the content below them.
Check whether keyboard and screen-reader users receive a logical outline instead of a sequence chosen only for font size.
A proxy response may differ from a fully rendered browser. Validate important findings in the final DOM when JavaScript changes the page structure.
A single descriptive H1 is a clear and dependable pattern. The more important requirement is that the page has an understandable primary heading and a logical outline.
It usually signals a missing section level. If the H3 is a subsection, introduce its parent topic with an H2 instead of selecting H3 for appearance.
The target may block cross-origin proxy requests, require authentication, rate-limit automated access, or render headings only after browser interactions.
Headings primarily improve organization and comprehension. They help systems interpret sections, but changing tags without improving the content is not a ranking guarantee.
