FAQ

Frequently asked questions

Why does heading hierarchy matter for SEO?

Headings help search engines understand the structure and topic hierarchy of your content. A logical order (H1 > H2 > H3) makes it easier for bots to crawl and index your page correctly.

Can I have more than one H1?

While HTML5 technically allows multiple H1s (one per section), SEO best practice is still to have exactly one H1 per page that matches your primary topic or title.

Is it okay to skip heading levels?

No, you should always go in order (H2 followed by H3, then H4). Skipping from H2 to H4 confuses both search engines and screen readers used by visually impaired users.

Should I include keywords in my headings?

Yes, including primary and secondary keywords in your H2s and H3s helps signal to Google what each subtopic is about.

How long should subheadings be?

Keep them concise and descriptive. Aim for 2-8 words that clearly summarize the section below.

What is the role of H4-H6 tags?

These are for further breaking down complex subtopics. They are less important for SEO than H1-H3 but still help with organization.

Does heading structure help with featured snippets?

Absolutely. Using questions as H2 or H3 headings and providing a direct answer immediately after is a great way to win snippets.

Can I use multiple H2 tags?

Yes, you can and should use multiple H2 tags to break up different main sections of your article.

Is this tool free?

Yes, the Heading Structure Validator is 100% free for all creators.

Does it work with Markdown?

Yes! Our validator automatically detects and parses Markdown headers (e.g. #, ##, ###) alongside standard HTML tags.

How do I fix a 'Missing H1' error?

Ensure that your main page title is wrapped in an <h1> tag. Most content management systems do this automatically, but custom HTML pages may need manual adjustment.

Is my content private during validation?

Yes. All parsing and validation happen locally in your browser. Your content is never sent to our servers.
