Drupal is one of the wonders of CMSs, emerging from the collaborative power of a global open-source community.
It is a little more complex than others and more of a CMS framework, but if you want to learn something and at the same time keep the power to expand, you can do magical things with it. When it comes to its flexibility, it requires a level of minimum technical knowledge, but once documented, creating a website and optimizing it could be just a game, thanks to its control over granulated access for any type of user.
Both Drupal 7 and 8 are considered very good content management systems at the moment, on the strength of their functionality as a whole. They are very powerful platforms, with lower resource consumption and can be used for any type of website, from a basic blog to a large content portal for a corporation that requires performance and a high degree of customization.
Visitor Analytics can now be added to your Drupal 7/8 site directly from Modules Market. You can either do a basic installation or add the service as a script.
For all the detailed steps on how to easily install Visitor Analytics on any Drupal website, as well as anything else there is to know about integration with this 3rd platform, please see the Installation Guide for Drupal Pages linked below.
