Clear headings improve readability and search visibility.
Strong heading flow helps users and search engines understand.
Use H1 for titles, H2 for sections, H3–H4 for details.
Keep H1 short, clear, honest, and used only once.
H2 defines sections and supports clean content structure.
H3–H4 break content into simple, readable parts.
AI prefers clean heading order and simple content flow.
