Just in case someone is trying to figure out how to get the Keywords to work according to the last post (like I was).
Use:
meta-keywords
instead of:
meta-keyword
Also why isn't this in the help documents?
You should also point out that you need to be sure you edit the php code in the header of your page and change the "pagename" to what you have the page named to within the CMS editor.
And lastly - These optimizations add the <p> tag to the meta tags so be sure you go back in and edit the opening and closing <p> tags out in your CMS editor.
