Read articleHeading Tags for SEO: How to Use H1 to H6 Correctly
Headings are the outline of your page for readers, Google and AI tools. Here is how many H1s you need, how to nest H2 to H6 and the mistakes that confuse everyone.
This guide explains how to use heading tags for SEO, from the H1 down to H6. It is part of my on-page SEO checklist.
Quick answer
Use one H1 that states the page’s main topic, H2s for the main sections, and H3s for subsections inside an H2. Headings should read like a table of contents, use the words people search, and never skip levels just for styling. Clear headings help readers skim, help Google understand the page, and help AI tools find the passage that answers a question.
What are heading tags?
Heading tags (<h1> to <h6>) mark the titles of sections on a page. Browsers show them larger, screen readers use them to navigate, and search engines use them to understand the page’s structure.
How many H1 tags should a page have?
Google has said multiple H1s are not a problem for Search. For clarity and accessibility, one visible H1 that matches the page topic is still the best practice. Google’s title link documentation also notes it may use the main visible heading when it builds title links, so a clear H1 helps there too.

7 rules for better headings
- Make the H1 match the topic of the title tag. See title tags guide.
- Use real questions as H2s where people search questions. It helps featured snippets and AI Overviews.
- Answer right under each question heading in 1 or 2 sentences.
- Nest properly: H3 inside H2, H4 inside H3.
- Keep headings short and descriptive, not clever.
- Use CSS for size and style, not heading tags.
- Include related terms naturally; do not repeat the main keyword in every heading.
Common heading mistakes
- Logo or site name wrapped in an H1 on every page.
- Headings used for styling sidebars, footers and buttons.
- Skipping from H2 to H5 because of design.
- No headings at all on long text pages.
- Every heading stuffed with the same keyword.
How to check your headings
Paste any URL into my free heading structure checker to see the outline, missing H1s and skipped levels. In WordPress, use the block editor’s List View to see the heading order.
Example
Before: H1 “Welcome”, H2 “Our Services”, H2 “Why Us”. After: H1 “Emergency Plumber in Leeds, 24/7”, H2 “What we fix”, H2 “How fast we arrive”, H2 “Prices”, H2 “Reviews from Leeds customers”, H2 “FAQ”. The second outline tells readers and Google exactly what the page offers.

Frequently asked questions
Can a page have more than one H1?
Google says it is not a problem for Search, but one clear H1 is better for readers and accessibility.
Are heading tags a ranking factor?
They help Google understand the page structure and topic. Clear headings support rankings and featured snippets, but they are not a strong factor on their own.
Should the H1 be the same as the title tag?
They should match in meaning. The title can be shorter and include the brand.
Can I skip heading levels?
Avoid it. Skipping levels makes the outline confusing for screen readers and harder to follow.
How long should a heading be?
Short enough to scan, usually under 70 characters, and clear about what the section covers.
