Heading tags are vital to user experience and a page’s rankings. For a website visitor, a heading tag can change the look and feel of a heading or subheading, usually making it bigger and bolder.
Heading tags indicate the hierarchy of a webpage to a search engine. An H1 tag is regarded as the main heading, followed by H2, H3, H4, and so on. These tags have SEO value dependent on their perceived importance.
Each heading tag will have a different look and feel in the browser, depending on your stylesheet, which can be edited in the CSS code of your site.
Like title tags, heading tags should be keyword-relevant, but since they act as part of the article, it is even more important that they are not stuffed with keywords for the sake of SEO alone.
SEO agencies can compose headings that use relevant keywords in a way that benefits search rankings without compromising on clarity for the reader.
