Why this matters
AI reads headings first
Before reading body text, AI scans your H1-H3 to understand what the page covers. Wrong structure = AI misunderstands your content.
H2s = AI sections
Each H2 becomes a 'topic' that AI can cite independently. 'How much does it cost?' as an H2 means AI can answer pricing questions from your page.
Accessibility + SEO
Proper heading hierarchy is required for accessibility (screen readers) and helps Google understand content structure. Double benefit.

Frequently Asked Questions
How do I check the H1 tag of a website?
Enter any URL in our Heading Checker above. We extract all H1-H6 tags in order, show the hierarchy visually, and flag issues like missing H1, multiple H1s, or broken structure.
How many H1 tags should a page have?
Every page should have exactly one H1 tag that describes what the page is about. Multiple H1s confuse both Google and AI crawlers about the page's primary topic. Use H2-H6 for sub-sections.
What is proper heading structure for SEO?
H1 for the main topic, H2 for major sections, H3 for sub-sections within H2s. Never skip levels (e.g., H1 → H3). AI uses this hierarchy to understand the structure of your content and extract key information.
Do H2 tags help SEO and AI visibility?
Yes — H2 tags tell AI what each section of your page is about. Use H2 headings that match what people ask AI (e.g., 'How much does it cost?' 'What features does it have?'). AI extracts these as section topics.
Should every page have an H1?
Yes. A page without an H1 is like a chapter without a title. AI crawlers use the H1 as the primary identifier for what the page is about. Missing H1 = AI doesn't know your page's purpose.
