Google Ads Source dbt Package (Docs)

What does this dbt package do?

• Materializes Google Ads staging tables which leverage data in the format described by this ERD. These staging tables clean, test, and prepare your Google Ads data from Fivetran's connector for analysis by doing the following:
  • Name columns for consistency across all packages and for easier analysis
  • Adds freshness tests to source data
  • Adds column-level testing where applicable. For example, all primary keys are tested for uniqueness and non-null values.
• Generates a comprehensive data dictionary of your google_ads data through the dbt docs site.
• These tables are designed to work simultaneously with our Google Ads transformation package.

How do I use the dbt package?

Step 1: Prerequisites

To use this dbt package, you must have the following:

• At least one Fivetran Google Ads connector syncing data into your destination.
• A BigQuery, Snowflake, Redshift, PostgreSQL, or Databricks destination.

Databricks Dispatch Configuration

If you are using a Databricks destination with this package you will need to add the below (or a variation of the below) dispatch configuration within your dbt_project.yml. This is required in order for the package to accurately search for macros within the dbt-labs/spark_utils then the dbt-labs/dbt_utils.

dispatch:
  - macro_namespace: dbt_utils
    search_order: ['spark_utils', 'dbt_utils']

Step 2: Install the package (skip if also using the google_ads transformation or ad_reportin combination package)

If you are not using the Google Ads transformation package or the Ad Reporting combination package, include the following package version in your packages.yml file. If you are installing the transform package, the source package is automatically installed as a dependency.

TIP: Check dbt Hub for the latest installation instructions or read the dbt docs for more information on installing packages.

packages:
  - package: fivetran/google_ads_source
    version: [">=0.11.0", "<0.12.0"] # we recommend using ranges to capture non-breaking changes automatically

Step 3: Define database and schema variables

By default, this package runs using your destination and the google_ads schema. If this is not where your Google Ads data is (for example, if your google_ads schema is named google_ads_fivetran), add the following configuration to your root dbt_project.yml file:

vars:
    google_ads_database: your_destination_name
    google_ads_schema: your_schema_name 

(Optional) Step 4: Additional configurations

Union multiple connectors

If you have multiple google_ads connectors in Fivetran and would like to use this package on all of them simultaneously, we have provided functionality to do so. The package will union all of the data together and pass the unioned table into the transformations. You will be able to see which source it came from in the source_relation column of each model. To use this functionality, you will need to set either the google_ads_union_schemas OR google_ads_union_databases variables (cannot do both) in your root dbt_project.yml file:

vars:
    google_ads_union_schemas: ['google_ads_usa','google_ads_canada'] # use this if the data is in different schemas/datasets of the same database/project
    google_ads_union_databases: ['google_ads_usa','google_ads_canada'] # use this if the data is in different databases/projects but uses the same schema name

NOTE: The native source.yml connection set up in the package will not function when the union schema/database feature is utilized. Although the data will be correctly combined, you will not observe the sources linked to the package models in the Directed Acyclic Graph (DAG). This happens because the package includes only one defined source.yml.

To connect your multiple schema/database sources to the package models, follow the steps outlined in the Union Data Defined Sources Configuration section of the Fivetran Utils documentation for the union_data macro. This will ensure a proper configuration and correct visualization of connections in the DAG.

Passing Through Additional Metrics

By default, this package will select clicks, impressions, cost, conversions, conversions_value, and view_through_conversions from the source reporting tables to store into the staging models. If you would like to pass through additional metrics to the staging models, add the below configurations to your dbt_project.yml file. These variables allow for the pass-through fields to be aliased (alias) if desired, but not required. Use the below format for declaring the respective pass-through variables:

IMPORTANT: Make sure to exercise due diligence when adding metrics to these models. The metrics added by default (taps, impressions, and spend) have been vetted by the Fivetran team, maintaining this package for accuracy. There are metrics included within the source reports, such as metric averages, which may be inaccurately represented at the grain for reports created in this package. You must ensure that whichever metrics you pass through are appropriate to aggregate at the respective reporting levels in this package.

vars:
    google_ads__account_stats_passthrough_metrics: 
      - name: "new_custom_field"
        alias: "custom_field"
    google_ads__campaign_stats_passthrough_metrics:
      - name: "this_field"
    google_ads__ad_group_stats_passthrough_metrics:
      - name: "unique_string_field"
        alias: "field_id"
    google_ads__keyword_stats_passthrough_metrics:
      - name: "that_field"
    google_ads__ad_stats_passthrough_metrics:
      - name: "other_id"
        alias: "another_id"

Change the build schema

By default, this package builds the Google Ads staging models (10 views, 10 tables) within a schema titled (<target_schema> + _google_ads_source) in your destination. If this is not where you would like your google_ads staging data to be written to, add the following configuration to your root dbt_project.yml file:

models:
    google_ads_source:
      +schema: my_new_schema_name # leave blank for just the target_schema

Change the source table references

If an individual source table has a different name than the package expects, add the table name as it appears in your destination to the respective variable. This is not available when running the package on multiple unioned connectors.

IMPORTANT: See this project's dbt_project.yml variable declarations to see the expected names.

vars:
    google_ads_<default_source_table_name>_identifier: your_table_name
