The H4 tag is an HTML element that defines the fourth-level heading (or subheading) on a web page to mark up a subsection of an H3 heading in the content. A web page can have any number of <h4> tags to break up the subsections of the <h3> subheading topics.
An H4 tag does not carry any weight for search engine optimization (SEO) because it’s too low in the informational hierarchy. You can choose to use H4 header tags to further break up an H3 subheading to help the users better understand the content, but trying to optimize the H4 tags for SEO will not provide any boost in search engine rankings.
