What is the most important tag for SEO?

[JohnSuper]

You might say that html, body, or head are most important as maybe search engines are not so forgiving of seriously faulty markup.

This poll is more for keywords - which tag is most important for keyword optimization?

title

h1

other (please specify in post)

Both title and H1 are importnat, hard to say which one is more! I might give more importance to title, since there can be only one per page and that is supposed to be a very short summery of what the page is about.

Rather than just h1 or h2, the size of the text matters. So if you use stylesheet to make h1 small font, may not workout very well. I have seen lots of people trying to abuse the title tag, without much success.
