I have just checked my keyword with a meta tag analyzer and it says my keywords come to 80%, but when I add 1 more to see if it take the percentage up a but more, it actually take sit down even though I added the keword in part of a sentance!
why care so much about your keyword density??? there are a lot of other things you should worry about, such as title, description, content, internal link structure, inbound links...etc
