GTag Extension for MediaWiki
The GTag extension lets you insert the new Google Analytics tracking tag on your MediaWiki site (gtag.js).
Download the file (a free account is required) and extract the file to your extensions directory. We recommend that you "follow" the download so that you are notified of new updates via email when they are released.
To install the extension, add the following to your LocalSettings.php file:
wfLoadExtension( 'GTag' );
$wgGTagAnalyticsId = 'UA-XXXXXXXX-X or G-XXXXXXXX'; // replace with your GA id
In addition to the required $wgGTagAnalyticsId, this extension features many optional configuration variables that you may add to your LocalSettings.php file.
$wgGTagAnalyticsId (string): Google Analytics ID, for example 'UA-XXXXXXXX-X' or 'G-XXXXXXXX'. Required.
$wgGTagAnonymizeIP (boolean, default false): If true, anonymize the IP address sent to Google Analytics.
$wgGTagHonorDNT (boolean, default true): If true, honor "Do Not Track" requests from browsers. If false, ignore such requests.
$wgGTagTrackSensitivePages (boolean, default true): If true, insert tracking code into sensitive pages such as Special:UserLogin and Special:Preferences. If false, no tracking code is added to these pages.
In addition to these configuration variables, you may assign the right gtag-exempt to user groups to prevent them from being tracked. This can be useful to give to staff groups so that your internal users and staff are not tracked, giving you a better idea of who is actually using your site. For example:
$wgGroupPermissions['sysop']['gtag-exempt'] = true;
Free community support is available on the mwusers.org forums. Paid support plans are available as well.
