Words placed within heading tags (often referred to as header tags, headings, or "h" tags) carry more weight with the search engines than plain text. An <h1> (header one) tag should always be used as the visible title within the design of the page. The <h1> tag should incorporate the primary keywords from the
title META tag of the page. "Heading Tags", for instance, is the <h1> tag used for this page.
It is a good idea to separate the text content on all pages into several paragraphs, giving each paragraph its own header which contains the keywords for that page.
