Titles & Headings
The single most important element of each webpage is the title. For standard articles this is pulled from the title used in the article.
Including relevant keywords in your title increases the chances of being recognised by search engines. Therefore something like “home” or “a story” is far less effective than “Using titles and headings in Joomla 1.5 websites”.
Titles should be unique and limited to 70 characters long (including spaces). If it exceeds 70 characters, then Google truncates the title to the first 64 characters. Avoiding words such as and, the, is, as, in etc. provides you with more space to use valuable key words. Just be careful it doesn’t become illegible.
Likewise a heading tagged in the Heading 1 format will be considered of great value (do not have more than one h1 tag per page though).
The other headers (Heading 2, Heading 3, Heading 4 etc) are also important keywords but they decrease in value.
