What correct heading structure looks like

One H1 per page: Every page should have exactly one H1, the main topic of the page. It should contain your primary keyword and clearly describe what the page is about.

H2s are your main sections: Use H2 tags for the major sections of your content. Each H2 should represent a distinct subtopic under the main H1 topic.

Don't skip heading levels: Going from H1 directly to H3 (skipping H2) confuses both Googlebot and screen readers. Maintain a logical hierarchy, H1 → H2 → H3.

H1 ≠ title tag: Your H1 is visible on the page. Your title tag appears in Google search results. They can be different, and often benefit from slight variations.

Real Heading Structure Checker example: before vs. after

A landing page's heading hierarchy, broken vs. fixed.

Before · Broken structure

H1: (missing)
H1: "Welcome to Our Site" (2nd H1)
H3: "Our Services" (skips H2)
H2: "Contact Us"

No clear H1, two competing H1 tags, and a skipped H2 level, Google has to guess what the page is actually about.

After · Fixed structure

H1: "Project Management Software for Startups"
H2: "Our Services"
H3: "Task Tracking"
H2: "Contact Us"

One keyword-relevant H1 and a clean H1 → H2 → H3 hierarchy, a clear, unambiguous topic signal for both Google and readers.

Frequently Asked Questions

Do heading tags affect SEO rankings?

Yes. H1 is one of the strongest on-page SEO signals: it tells Google the primary topic of your page. H2–H3 tags reinforce the topical structure and help Google understand your content depth.

Can I have multiple H1 tags?

Technically yes, but SEO best practice is one H1 per page. Multiple H1s dilute the primary topic signal and can confuse Googlebot about what the page is actually about.

What if my CMS doesn't let me set headings?

Most CMS platforms (WordPress, Shopify, Webflow) let you set heading levels in the page editor. Check your theme, sometimes a theme's built-in 'page title' uses H1, and you should use H2 for your content headings.

Is a missing H1 a critical SEO issue?

Yes. Without an H1, Google has to infer your page topic from context. This weakens your relevance signal for your target keyword. Always add a clear, keyword-relevant H1.
