Google Analytics (WID:20200812160510-google_analytics)

Google Analytics if a very used system to track actions in a website. It is provided as a free service by Google, and at it\'s most simple it is very easy to integrate into an existing website.

Basically, to make a GA work on a website, you only need to add the tracking code provided when you create a property.

The gtag function

The gtag function is the main way of interacting with GA. The basic shape is gtag('<type>', '<key>', <parameters>*).

The most basic functionality is just to specify the config (which is like registering a property with the library):

gtag('config', 'UA-XXXXXXX-X');

More information about this can be found in the documentation.

Triggering events

We can register arbitrary events with GA also through the gtag function, in the following way:

gtag('event', eventName, {
    eventCategory: eventCategory,
    eventLabel: eventLabel,
    eventAction: eventAction,
    eventValue: eventValue
});

These events will then appear in the GA dashboard and be there for us if we want to analyze them.
