How many H1 tags should you use per page?

Best practice dictates using only one H1 tag per page. The H1 tag serves as the main heading, signaling the primary topic of the content to both users and search engines. Multiple H1s can confuse search engines about the page's main subject and dilute its SEO value. While HTML5 technically allows for multiple H1s within different sectioning elements, search engine algorithms still generally interpret a single H1 as the most authoritative signal for the page's overall theme. Using two to three H1s, or as many as needed, or having no limit, goes against established SEO best practices for clear content hierarchy and optimal search engine understanding.
