Enable Google Analytics on all of your pages instantly and add Google Analytics Stats to your Admin Dashboard and Posts.
Installing is as simple as downloading the file from this site, placing it in your wp-content/plugins directory and activating the plugin. For the more detailed instructions read on.
Please note that SimpleXML (http://us3.php.net/manual/en/book.simplexml.php) is needed for the stats part of this plugin. It is enabled by default in PHP version 5 but some hosting environments may have it turned off. The plugin will alert you if SimpleXML is not available. You may be able to contact your hosting company to enable this for you. Also, if it is not available the Javascipt insertion of the Google Analytics code will still work. Only your stats will be unavailable through the Dashboard and Post Section.
