Did exactly what it was meant to do. Thanks a ton for developing it and removing the google bad guys headache.
Also special thanks to the two reviewers before me, generally avoid extensions which have not been rated and reviewed, but your confidence in the plugin helped me try it out.
Just two common sense hints
1. You must publish the plugin
2. You need to use this with the meta tag method (and not the file in root) and copy the key that google gives you within the quotation marks, including the '=' sign into the key of the plugin.
Very simple to use.
Well done.
