An event is the user’s interaction/activity with a web page element embedded on a website and/or mobile app.

The ‘recommended events’ are one of the four categories of events in Google Analytics 4(GA4). The other three categories are:

1. Automatically Collected Events
2. Enhanced Measurement Events
3. Custom Events

Recommended events are the events recommended by Google. They do not automatically get triggered and logged unless you manually implement them.

However for a recommended event to work correctly, you must use the exact same event name and parameter(s) as supplied by Google. 

Failing to do so, Google will not recognize your event as one of their recommended events and your event may either do not work the way you want or do not get triggered at all.

Google recommends events based on business verticals. 

For example, Google has recommended a certain set of events and parameters for the following business verticals:

1. Retail/ecommerce
2. Travel/Hotel
3. Gaming
