H6 Tag Definition & Meaning

The H6 tag is an HTML element that defines the sixth-level heading (or subheading) on a web page to mark up a subsection of an H4 heading in the content. A web page can have any number of <h6> tags to break up the subsections of the <h4> subheading topics.

H6 tags are not used much on standard web pages because most topics do not need to go this deep. H6 header tags are often reserved for technical documents that require finer points and details to explain a fifth-level subheading.

As a result, an H6 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 H6 header tags to further break up an H5 subheading to help the users better understand the content, but trying to optimize the H6 tags for SEO will not provide any boost in search engine rankings.
