Headings and the H1: how to structure a page for SEO

Headings and the H1: how to structure a page for SEO

Headings are the outline of a page. The H1 names the page's main topic, and H2 to H6 headings break the content into sections and sub-sections. A clear outline helps search engines understand what each part of the page covers, lets screen-reader users jump between sections, and gives AI assistants clean passages to quote.

How many H1s should a page have?

Use one visible H1 per page that states the main topic in plain words. HTML allows more than one, and Google says it copes either way, but a single H1 keeps the page's subject unambiguous for every reader and tool.

What does a good heading structure look like?

H1  Dental implants in Pune
  H2  What is a dental implant?
  H2  How long does treatment take?
    H3  Consultation and scans
    H3  Placing the implant
    H3  Fitting the crown
  H2  How much do dental implants cost?
  H2  Frequently asked questions

Each level sits inside the one above it. Do not skip from H2 straight to H4, and do not use heading tags just to make text big; use CSS for styling.

Should headings be questions?

Where it fits, yes. Headings that match the questions people type, followed by a direct answer in the first sentence or two, are the passages search features and AI assistants pick up most easily. See how to appear in AI search.

Does the amount of content under each heading matter?

There is no ideal word count, but pages with only a few sentences rarely rank for anything competitive. Cover the topic fully enough that a reader does not need to go back to the results: answer the main question, then the questions that naturally follow.

Common mistakes

  • No H1, or an H1 that only contains the logo.
  • Headings used for styling, such as a footer full of H2s.
  • Vague headings such as "Overview" or "More info" that say nothing about the section.
  • The same H1 on many pages.
