It's been a while since the updates, but we have rebuilt and updated! We've looked at code, implementation method, support requests and much more in our new and improved version. It's been ten years and over 70,000 downloads of our free version of our plugin.

Here is what you will find in the FREE version of our Google Analytics Plugin.

Google Site Verification

Google Search Console Tools verification method. We've included the HTML meta tag verification method. This method is still the easiest verification method. However, if you're using this plugin for Google Analytics or Google Tag Manager, they too can be used to verify your site on Google Search Console.

Google Analytics

The asynchronous (where this plugin initially started) and universal versions of Google Analytics still work but have been superseded by the Global Site Tag (gtag.js).

Our method correctly renders the tracking code into the head of your Joomla website. Obtain your tracking ID from your Google Analytics account, and input it into the parameters of the plugin configuration screen and you're good to go!

Google Tag Manager

For those that want to take things further and integrate Google Analytics along with other third-party tracking scripts such as Hotjar, Heap Analytics, HubSpot or Facebook pixel tracking, then this advanced method is the way to go. Tag Manager will allow you to add and manage all the additional scripts within its interface outside of your website.

Our plugin correctly integrates the Tag Manager container ID into your Joomla website.

Obtain your container ID from Tag Manager and configure it within the plugin to start using Google Tag Manager on your Joomla website.

Google Analytics and Google Tag Manager options can be used in combination to manage different combinations of script execution.

Documentation

More and more documentation! Documentation is one of the biggest requests we have had, and we've added more and will be adding more documentation on how to used our plugin and to get the most out of Google Analytics and other third-party tracking tools.
