Check website H1, H2 and H3

Online H1–H3 heading check

Headings help visitors and search engines understand a page's structure and main topic. This tool checks H1, H2, and H3 tags at the specified URL and shows which headings are found and their order.

What the service checks

The check detects the main H1 heading, lists all second- and third-level headings, and helps reveal possible structural issues. It lets you quickly spot a missing H1, multiple main headings, overly generic wording, or an illogical section hierarchy.

Why analyze H1, H2, and H3

A correct heading structure makes content easier to read: users immediately see the main page topic and can quickly move to the needed section. For SEO, it is an additional signal about the document's content and the relationship between its parts. Analysis is especially useful after publishing new pages, redesigning a website, migrating content, or introducing a new template.

How to use the results

Usually, one H1 that accurately reflects the main topic is enough for a page. Use H2 for major content blocks and H3 for subsections within them. Write clear, meaningful headings, add keywords only where they sound natural, and do not use heading tags solely to change text size.
