Frequently Asked Questions

Why is the H1 tag important?

The H1 is the main heading of a page and signals the primary topic to search engines. Every page should have exactly one H1.

What are skipped heading levels?

Skipping from H1 directly to H3 (without an H2) breaks the logical hierarchy. This hurts accessibility and can confuse search engines.

Can I have multiple H1 tags?

While HTML5 allows multiple H1s, SEO best practice is to use a single H1 per page for clarity.

Do headings affect SEO?

Yes, proper heading structure helps search engines understand your content hierarchy, which can improve rankings and featured snippets.
