Without titles, a page cannot be found. Use many, carefully selected headings, with names that conceptually relate to the information or functions they describe. Headings provide strong cues that orient viewers and inform them about a page's organization and structure.
Headings also help classify information on a page.
Well-designed headings are an important tool for helping users scan text. Headings are often removed from the context of the full page and used in tables of content and search engine results. This means that the headings should clearly tell users what is at the other end of the link.
