This is a sidebar, but Google's technology is unaffected by Meta tags, because its rankings are based on how many other sites contain links to yours, not on a word count from your HTML. There are ways to artificially inflate the rankings, of course, but Meta tags wouldn't do it.
Google does use tags and embedded language to define content. Their ranking may be based on more discreet information, but a link from 'netquote' doesn't in and of itself define Geico as Geico the Auto Insurer.
