note that google ignores the keywords tag

Answer 2

Don't go too crazy. Meta Keyword isn't something that Google rates very high (if at all) on its list of things that move you up in the rankings. It's due to the fact that not too long ago, people would load the meta tags with "hot" terms so they would get all sorts of traffic. The search engines got smart.
