Using Heading Tags for on-page SEO
In descending priority of importance, H ref tags should be used to group content on the page, and the titles need to include one or more of the primary focus keywords within the title text.
Heading tags (<H1> to <H6>) are given an additional boost in Search Engine rankings by search engines. The reason for this is that headings traditionally carry important information about the structure of a page. For this reason, it is preferable to use headings to mark important elements in a document and to utilise keywords within the heading tags.
Use your keywords in the headings. Make sure the first level (<H1>) includes your most important keywords.
For greater SEO, only use one <H1> title per page.
