Frequently Asked Questions

Headings help search engines understand your content's structure and hierarchy. A well-organized heading structure improves crawlability, accessibility, and can influence featured snippet selection.

Best practice is to have exactly one H1 per page. HTML5 technically allows multiple H1s, but using a single H1 that describes the page's main topic is clearer for search engines and users.

Skipped levels occur when you jump from H2 directly to H4, for example. Headings should follow a logical hierarchy (H1 > H2 > H3) without gaps to properly structure your content.

Keep headings concise and under 70 characters when possible. Long headings are harder to scan and may not display well in search results or table of contents.
