A webpage has over 200 elements that can affect ranking. Although, it has been proved that you can get into a top position on links alone with even a blank page, who wants to? So I came up with a few "gotta haves" that should be in all your webpages. ( If you want to position well in the engines that is).

Robots.txt
w3 declaration
Google/Yahoo sitemap
Character Encoding in Header
Language Encoding
Links back to your home page that say your main keyword instead of "home page".
Title &, Description tags.
