whats the most important part of html page in terms of SEO keyword targeting- the title?

From stackoverflow

• In my experience:

  1. The domain name (www.mykeywords.com)
  2. The name and path of the page itself (/key/word/lots-of-keywords.html)
  3. The Title (keywords first, the shorter the better)
  4. Header tags (from h1 -> h3)
  5. Stuff closest to the top of the page.
