Valid HTML

I have seen varied opinions on this, but have never seen good evidence of the search engines penalizing pages that are not valid html. By valid html here we mean strictly conformant to the W3C specifications. This is a surprisingly high bar (most web pages are not stricly valid). Obviously, if your pages are very badly constructed, so that for example the major browsers cannot display them, then you may have trouble getting the crawlers to index them properly.
