well, if it's going in the header, then you'd drop it into the header insert in the cp; I do this at UGN Security (see my sig).
Be sure though, if you're using a program such as Dream Weaver or Front Page that you only copy the new content, most of these programs will add extra meta tags and html that you DO NOT NEED...
And if you're looking for a contractor to help you through things, I'm always available.
