your right that search does use meta tags but this is one of those freak occurences i was talking about
i read about it recently and everyone was shocked that a forum members site was described using meta tags
in essence google uses it as back up
the priority for google is this
Highest ranking: domain based. ie: search for mp3 turns up
www.mp3.com.
Appears whois domain information may be being used. The frequency of INC in the top ten results is no accident. We feel they are using Whois data now to influence results. (sept 1, 2000).
Page Linkage. Read their info on Page Rank. Highly informative and good reading for the search engine addict.
Title. As always, it is important, but it doesn't appear to hold the weight that other search engines give it.
GOVT, EDU, COM, NET seems to be the order of relevancy with some foreign domains ranking higher than their American .com mirror counterpart. Althought, .gov's and .edu's are starting to take a nose dive in Google due to the effects of Page Rank (.edu's and .gov's have historically had low linkage numbers).
Reciprocal Linkage text. (text of a link pointing to your site).
Keyword text within headings. h1...h6
Bold faced words or large font words.
Page size : smaller is better.
Stay away from dynamic page extentions (.asp, shtml, shtm, jsp...etc).
Density is not a major factor. In testing, keyword density has been all over the map from 20% to even 0%, yes zero (its that links thing again).
