Heading structure and SEO

How search engines read headings

Headings H1–H6 form the “table of contents” of a page. Search engines use them to understand the topic and structure of the content, and also to build sitelinks in the snippet.

The tool displays the page’s heading tree and finds duplicate H1s, empty headings and skipped levels — all the typical problems that arise during markup.

The right hierarchy

H1 is the page topic, one per document. H2 are the main sections, H3 are subsections within them. Do not use headings just for font size — that is what CSS is for.

Also check that the H1 does not repeat the title word for word: a small difference lets you cover more query wordings.

Frequently asked questions

How many H1 tags should a page have?+

The classic recommendation is one H1 per page reflecting its main topic. HTML5 allows multiple H1s in different sections, but for SEO and accessibility it is safer to stick to one.

Can I skip heading levels?+

It is not advisable. Jumping from H2 straight to H4 breaks the logical structure of the document. Search engines and screen readers use the heading hierarchy to understand the page content.

Do headings affect ranking?+

Yes. The H1 is one of the significant text factors, and H2–H3 help search engines understand the structure and coverage of the topic. Keywords in headings are taken into account by both Yandex and Google.

Should headings be built from keywords?+

A heading should first of all be useful to the reader. Keywords are appropriate, but stuffing H1–H2 can lead to over-optimization penalties, especially in Yandex.
