Paul Bearne

This is a simple tool that helps you provide the site verification code and file generator for any service that needs to verify the site 
via a comment / meta in the head section or via a file URL.
This is a generic site certification tool. 
To use it, just add the plug-in and turn it on as needed. 
You will no longer need to FTP a file to the site root or add extra tags to the header.php in the template to enable your site to be verified by third-party services.
Some examples: 
Google webmaster tool needs a file called googleXXXXXXXXXXXXX.html with no contents. 
OR 
<meta name=”google-site-verification” content=”XXXXXXXXXXXXXXXXXXXXXXXXXXXXX” /> in the HTML head, 
Without this plugin, you would have to create a file and FTP it to your server or edit your template. With the plugin, you can generate the verification method needed automatically via the control panel.
Similarly, Trustwave SSL wants a file called cert.html with the contents of 
“Trustwave SSL Validation Page”

WP Site Verification tool
