Enter any URL to analyze its heading hierarchy. Check H1-H6 structure, find skipped levels, and ensure your headings follow SEO best practices.
Why heading structure matters for SEO
Heading tags (H1-H6) create a content hierarchy that helps both search engines and users understand the structure and topics of your page. Google uses headings to grasp the main subjects covered on a page, and screen readers rely on them for navigation. A clear, logical heading structure improves crawlability, accessibility, and can boost your rankings by signaling well-organized content.
Heading tag best practices
- Use exactly one H1 per page. The H1 should clearly describe the page's primary topic. Multiple H1s dilute the main message and confuse search engines.
- Follow a logical hierarchy. Headings should nest properly — H2s under the H1, H3s under H2s, and so on. Think of it as an outline for your content.
- Include your primary keyword in the H1. This reinforces the page's topic for search engines. Keep it natural and descriptive.
- Don't skip heading levels. Jumping from H2 to H4 breaks the logical flow. Screen readers and search engines expect a consistent hierarchy.
- Use headings for structure, not styling. If you need bigger or bolder text, use CSS — not heading tags. Reserve headings for actual content sections.
Common heading mistakes
- Missing H1: Every page needs an H1 tag. Without one, search engines lack a clear signal about the page's primary topic.
- Multiple H1 tags: Using more than one H1 weakens the topical focus of your page and can confuse crawlers about which heading is most important.
- Skipping levels: Jumping from H1 to H3 or H2 to H5 breaks the document outline and hurts accessibility.
- Empty or generic headings: Headings like "Read More" or "Section 1" waste an opportunity to include descriptive, keyword-rich text.
- Using headings for visual styling: Applying H3 or H4 tags just to make text look a certain way creates a misleading content structure.
