Headings Tell Google What the Page Is About
An H2 followed by an H4 followed by another H2 is a heading hierarchy that confuses both screen readers and search engines. The checker visualises the full structure and flags every skip, duplicate, and empty tag.
Run it on top-ranking pages and you usually find at least one or two ranking opportunities lost to a fixable heading mess.

FAQ
Frequently Asked Questions
Everything you need to know about heading tags and SEO.
Why are heading tags important for SEO?
Heading tags (H1 through H6) outline the structure of a page for both search engines and screen readers. Google uses them to understand the topic hierarchy, AI Overviews quote passages by heading depth, and assistive tech relies on them to navigate. A clean H1-H6 outline directly influences how a page is summarized, indexed, and ranked.
How many H1 tags should a page have?
One. Best practice for SEO and accessibility is exactly one H1 per page, used for the main page title. HTML5 technically allows multiple H1s inside sectioning elements, but Google and most screen readers still treat the first H1 as the page-level title. If you have multiple H1s, demote the extras to H2 or H3.
What does a skipped heading level mean?
A skipped level is when the heading hierarchy jumps levels, for example going from H1 directly to H3 with no H2 in between. This breaks the outline for screen readers (they announce sections as missing) and confuses Google about the page structure. Always step down one level at a time: H1 → H2 → H3, not H1 → H3 or H2 → H4.
Can I check headings on password-protected or JavaScript-rendered pages?
This Heading Tags Checker fetches the raw HTML of a public URL, so it sees what the server first sends. Pages behind a login (protected with HTTP auth or a session cookie) return a login screen instead of content. For JavaScript-rendered pages where headings are injected after page load, the tool reads only what is in the initial HTML response.
What is the correct heading structure for SEO?
The correct heading structure has one H1 at the top describing the page topic, then H2s for major sections, H3s for sub-sections inside each H2, and so on down to H6 if needed. Levels should always step down one at a time, never skip. Section headings should describe the section content, not act as decoration. This Heading Tags Checker shows the full tree so you can spot breaks at a glance.
Can a page have multiple H1 tags?
Technically yes, the HTML5 specification allows multiple H1s inside <section> or <article> elements. In practice Google still treats the first H1 as the page-level title and most screen readers announce all H1s, which can confuse users. The safe rule in 2026 is one H1 per page. Use H2-H6 for everything else.
How do I check heading tags without a tool?
Right-click any page and select View Page Source (or press Ctrl+U). Press Ctrl+F and search for "<h1", then "<h2", and so on. Note the order they appear and whether any level is missing. This works for the raw HTML only, JavaScript-injected headings will not show. For a faster check across all six levels, use this Heading Tags Checker which lists the full H1-H6 tree from any URL in one click.
Why does heading hierarchy matter for accessibility?
Screen reader users navigate web pages by jumping between headings using shortcut keys. A correct H1-H6 hierarchy lets them skim a page the way sighted users skim with their eyes. A missing H1 leaves them without a title anchor. Skipped levels (H1 to H3) sound like a content gap. Empty or duplicate headings break navigation entirely. Heading structure is a WCAG 2.2 requirement, not a nice-to-have.
