How to use the Metric Builder for Google Ads

A
Data Source: This is the Data Source that the Custom Metric is syncing data from.
B
Report: Select a Report from your Google Ads Data Source, such as "Account Performance Report," "Campaign Performance Report," or "Ad Performance Report." This selection determines where the data is being synced from the Google Ads Account and what data is included in the returned Custom Metric value.
C
Metric: Select a Metric from your connected Google Ads Data Source, such as "Impressions," "Avg. CPC" or "Conv. Rate."
D
Dimension (Optional): The Dimension parameter re-categorizes the returned Metric value based on common criteria. In general, the Report selection determines the Dimension options. For example, if you select
Campaign Performance Report as the
Report, you can select
Campaign as a Dimension. If you select
Ad Performance Report as the
Report, you can select
Ad as the Dimension.
Pro Tip: Add the word "by" in between the Metric and Dimension in order to determine an appropriate Custom Metric Name. From the Metric and Dimension examples outlined above, we could create the Custom Metrics "Reach by Campaign," "Clicks by Region," or "Impressions by Device Platform."
E
Invert Metric (Optional): This checkbox should be selected if a lower Metric value indicates positive growth / performance (i.e., Unsubscribers, Cost per Conversion, etc.) Inverting the Custom Metric in Databox will make it so an increase in the Metric value will show a red percentage change color on a Databolock, while a decrease in the Metric value will show a green percentage change color on a Datablock.
F
Filter by(Optional): Filters restrict the data that gets included in the Custom Metric. All data that is returned is tested against the Filter(s). Multiple Filters can be combined using AND boolean logic.
If the data synced from the Metric and Dimension fields meet the Filter specifications, the data is retained and included in the Custom Metric value. If the data synced from the Metric and Dimension fields don't meet the Filter specifications, the data is excluded from the Custom Metric value.
Pro Tip : If you don't know which Filters to put in place for your use case, use the Dimension + Data Preview to troubleshoot and get more insight into the data that is returned from your Google Ads Account for each field. Learn more

G
Data Aggregation: The Data Aggregation field is optional when a Dimension is selected for the Custom Metric. The Data Aggregation selection determines how the system will handle duplicate results that are returned from the Google Ads Account.
For example, if you create a Custom Metric called "Impressions by Campaign," the same Campaign will have multiple results synced Gooogle Ads Account. In that case, you would want to add together all individual Campaign entries of the same Campaign to produce aggregate values. So, you would select
SUM as the
Data Aggregation.
If you create a Custom Metric to track "Avg. CPC by Campaign," you would want the average of all individual Campaign entries of the same Campaign. In this case, you would select
AVG as the
Data Aggregation.
H
Data Preview: After clicking
Preview Data, a Data Preview of the Custom Metric will be displayed. Daily Metric values are displayed in this section, along with the total Metric values for the Date Range in bold at the bottom. You can view the Data Preview for different Date Ranges by clicking on the drop-down list at the top of the Data Preview.
I
Custom Metric Name: Enter a name for your Custom Metric. This Custom Metric name will be available in the Designer after saving.
J
Save: Save your Custom Metric.
How to create a Custom Google Ads Metric [Example]
In this example, we'll create a Custom Metric to report on "Click through Rate (CTR)" tracked in the Google Ads Account, split up based on the Campaign. We only want to view this data for Campaigns that we're actively working on, so "Cost" is above $0.
1
Navigate to
Metrics > Custom Metrics
2
Click the green
+ New Custom Metric button
3
Select the appropriate Google Ads Data Source
4
Since we want to view this on the Campaign level, we'll select
Campaign Performance Report as the
Report.
5
For the
Metric, we'll select
CTR
6
We want to split up all CTRs based on the Device where the action was performed, so we'll select
Campaign as the Dimension.
7
We want to restrict the Custom Metric to only retain data for Campaigns we're spending money on, so we'll add a Filter to the Custom Metric.
First, click on the
Advanced Options hyperlink to open the Filter section of the Metric Builder. Click on the
Field dropdown and select
Cost. Next, click on the
Operator dropdown, and select
Greater than. Lastly, in the
Value textbox enter
0.
8
Daily CTRs for each Campaign will be returned for this Custom Metric. When multiple results are returned for the same Campaign (i.e., Campaign 1 CTR on May 1 = 5.5, Campaign 1 CTR on May 2 = 6.5, etc.), we need to set a rule for how this is handled. In our case, we want to average the returned values to produce an Avg CTR value for each Campaign.
So, we'll select
AVG as the
Data Aggregation.
9
In order to accurately explain what this Custom Metric is reporting on, we'll name the Custom Metric "CTR by Campaign"
10
Click
Preview data to generate a Data Preview of the Custom Metric.
11
Once we confirm that these are the results we're looking for, we'll click
Save to save the Custom Metric.

Additional Information
- Using the Metric Builder for Google Ads, the "Criteria" Dimension differs depending on the Report you have selected. The "Criteria" returned always matches the first word of the Report selected (i.e. Keyword Performance Report ("Criteria" = "Keywords"), Gender Performance Report ("Criteria" = "Gender"), Geo Performance Report ("Criteria" = "Geo").
- When using the "City","Region" or "Country/Territory" Dimension, only ID's are returned and not the actual geographical names. You can use the feature within Metric Builder that enables you to rename or exclude Metric Dimensions. Learn more here.
