Frequently Asked Questions

What is heading structure?

Heading structure refers to the hierarchy of HTML headings (H1-H6) in your content. H1 is the main title, H2s are major sections, H3s are subsections of H2s, and so on. Proper structure creates a logical outline of your content.

Why does heading structure matter for SEO?

Search engines use headings to understand content hierarchy and topics. Proper structure helps Google identify your main topic (H1) and subtopics (H2-H6). Well-structured content tends to rank better for featured snippets and related searches.

What are common heading structure mistakes?

Common issues: multiple H1s, skipping levels (H1 → H3), using headings for styling instead of structure, no H1 at all, headings in wrong order. These confuse search engines and screen readers about your content hierarchy.

How many H1 tags should a page have?

Generally, one H1 per page. The H1 should be your main title/topic. While HTML5 technically allows multiple H1s in different sections, for SEO and clarity, one H1 is best practice. Use H2-H6 for all other headings.

Does heading structure affect accessibility?

Yes, significantly. Screen reader users navigate by headings—they're like a table of contents for blind users. Skipping heading levels or using them incorrectly makes content difficult or impossible for these users to navigate.

How do I fix heading structure issues?

Ensure you have exactly one H1 (your title). Follow it with H2s for main sections. Use H3s only under H2s, H4s only under H3s, etc. Never skip levels. If you need larger text without a heading, use CSS instead of heading tags.
