Heading outline
Why heading structure matters
Headings are how people skim a page, and how search engines and AI assistants work out what each section is about. A clear outline, one H1 stating the page topic and H2s for each main question, makes it easier for Google to match sections to searches and for answer engines to lift a section as a direct answer.
- Use one H1 that says what the page is about.
- Use H2s for main sections, and H3s only inside an H2.
- Write headings as the questions or topics people search for.
- Don't use heading tags just to make text big; use CSS for styling.

Frequently asked questions
How many H1 tags should a page have?
One is best practice. Google can handle more, but a single H1 that states the page topic is clearest for readers, search engines and AI assistants.
Is it bad to skip heading levels?
It isn't a ranking penalty, but jumping from H2 to H4 makes the outline harder to follow for screen readers and for systems that summarize your page. Keep levels in order.
How do I check the headings on a web page?
View the page source (Ctrl+U or Cmd+Option+U), copy it, and paste it into this checker to see the full H1 to H6 outline and any issues.
