I used google.co.uk to look up the word "Bisous", which a rather lovely young lady from Paris used at the bottom of an email to me. Turns out it means "kisses for a friend".
As with most searches I do these days I had a good close look at the top ten. All the top positions are definitions of the word in one form or another, but there at #8 was a British site selling Belgian chocolates made to look like a human @nus... Well it certainly caught my attention... Why was this site anywhere near this serp?
Looking at the source code it transpires that the word "bisous" is included in the meta-keywords. There's no inclusion of the word in the text on the page and nothing in backlinks that I can find.
Although I'm loathe to draw any firm conclusions, it does suggest that Google is paying some form of attention to the meta-keyword tag. As this tag is an obvious place to keyword-stuff it might merit another look at your tags. I actually went through my site a couple of weeks ago and reduced the content of the keyword tag to one word or a two-word phrase that best described the page at hand. I think this example serp justifies the effort that took.
Incidentally, that serp still stands at the time of writing if anyone wants to do any further research...
