What Scope Applies to Custom Metrics?
Answer: Hit
On the Google Analytics exam, you’ll likely be asked, “What scope applies to Custom Metrics?” A typical question will be formulated like the one below:
Event
Session
User
Hit
The correct answer is Hit.
Custom Metrics, just like Custom Dimensions, can have various scopes. According to Google, “Scope determines which hits will be associated with a particular custom-dimension value.” The four answers above are the four levels of scope.
Custom Dimensions with hit-level scope will only apply its value to the hit with which the value was set. In the same vein, Custom Dimensions with product-level scope will only apply value to the product with which the value was set.
Session-level scope works a bit differently. If two values with session scope have the same index in a single session, the final value set will apply to all hits in the session.
Finally, as far as user-level scope, two custom dimension values set in the same session will allow the last value set to take precedence and be applied to future sessions.
