What Is Heading Hierarchy?
Heading hierarchy refers to the logical structure of HTML headings (H1 through H6) on a web page. A proper heading hierarchy helps search engines understand your content structure and improves accessibility for screen reader users. The H1 tag represents the main topic, H2 tags represent major sections, H3 tags represent subsections, and so on. Skipping levels (e.g., jumping from H1 to H3) or having multiple H1 tags can confuse both search engines and assistive technologies, potentially harming your SEO and user experience.

Frequently Asked Questions
Should I have only one H1 tag per page?
While HTML5 technically allows multiple H1 tags in different sectioning elements, SEO best practice recommends using a single H1 tag per page that clearly describes the main topic. This makes it easier for search engines to understand your content.
Does heading structure affect search rankings?
While headings are not a primary ranking factor, they help search engines understand content hierarchy and can influence featured snippet selection. Proper heading structure also improves user experience, which indirectly supports SEO performance.
