"Some of you aren't able to use our existing verification method, so we asked for your feedback on an alternate method of verification that uses a meta tag on the root page of your site. The response was overwhelmingly positive, so we've added this method as an option.""To verify ownership of your site using this method, simply click the Verify link for your site, choose Add a META tag as the verification option, and then copy the tag provided to the <head> section of your home page. Once you've done that, select the checkbox and click Verify."
