In Custom Metrics there are two types of metrics:

Query Metrics

A query metric is a specific metric from a single data source that may or may not have a filter applied to it.

Example 1:

Clicks from Facebook Ads in Colombia

Example 2:

Clicks from Facebook Ads but for a specific campaign

Example 3:

Clicks from Facebook Ads for desktop

Calculated Metrics

Calculated metrics are formulas that may include Query Metrics

Example: we have an account that spends money on Facebook and Google, and we want to calculate the total spent for the account:

First, we need to create two query metrics:

Then we add them together in a calculated metric:

*Metrics need to be inside [..]

We could do the same for conversions, adding conversions from Meta and Google, and calculating the conversion for the whole account. Finally, with a new calculated metric, we can calculate the cost per conversion of the whole account = [Spent $ Total] / [Conversiones Total]
