Continuing from my previous post:
When starting to work with Google Webmaster Tools you will be asked to verify that you are the owner of the site. In reality it drills down to a check if you can add a meta tag or a html file to the website in question. FTP access is all that is needed.
If you choose meta tag, Google will ask you to add something like this:
<meta name=”verify-v1″ content=”<some string here>” >
