How to Conduct a Heading Hierarchy on Webflow

Establishing a clear heading hierarchy is crucial for user experience and SEO. Properly structured headings (<h1>, <h2>, <h3>, etc.) help organize your content, making it easier for users to read and navigate while also signaling to search engines the importance and structure of the content on your page.

How to do it on Webflow?

Use <h1> for your main title, <h2> for primary sections, and <h3> for subsections, following a logical order that reflects the structure of your content.
