H1 Tag Definition & Meaning

What Is the H1 Tag?

The H1 tag is an HTML element that defines the first-level heading on a web page to mark up the main subject for the content. The tag is often coded in website themes to be the first visible header tag on the page and includes the content’s title.

An H1 tag also carries the most weight for on-page SEO compared to the H2-H3 tags and is often confused with meta title tags, even though their roles differ.

A title tag is displayed for a web page listing in the search engine results pages (SERPs) to reassure a searcher that the page contains information relevant to their query, while an H1 tag introduces the post’s or page’s topic on the page. An article’s H1 and title tag can be the same or different; however, the best search engine optimization (SEO) practice is to make them identical or very similar.

A single post or web page should contain just one H1 tag introduced before the rest of the content. Putting text into the H1 header tag signals its importance to the search engine, improving a page’s chances of ranking on the first page of search results for a specific keyword.
