I can see how it could look that way. In fact, I never actually entered the keywords. We've been developing this site for the client. It appears that they've gone to the page settings and added them there. If I take out the keywords, the issue goes away. They have no access to the default.aspx file, and we never edited it for them.
What appears to be happening is that there are 2 places to enter keywords in the settings of the page. The first is in the basic settings. The second is in the advanced settings. If the words are in the advanced settings sections, it appears above the page. In the basic settings, this does not happen.
Someone suggested this could be an issue with the skin, have you heard of this being the case previously?
