Page Summary

outlined_flag

• Assets and their attributes can be retrieved using a Google Ads Query Language (GAQL) query on the asset entity.

• Type-specific attributes for assets like images or YouTube videos can be added to the query to access their unique properties.

• Asset metrics can be queried at the ad group, campaign, or customer level using resources such as ad_group_asset, campaign_asset, and customer_asset.

• Ad-level performance metrics for assets, particularly for App ads, are available through the ad_group_ad_asset_view, which also includes a performance_label to indicate asset performance.

• The source of mutable assets can be found in Asset.source, while the source of RSA Assets is in AdGroupAdAsset.source.

You can get a list of assets and their attributes by sending a Google Ads Query Language (GAQL) query to the GoogleAdsService. Assets are represented by the asset entity, which exposes a number of asset-specific fields.

Asset attributes

The following GAQL query lists all assets in a Google Ads account along with their resource name and type.

SELECT
  asset.id,
  asset.name,
  asset.resource_name,
  asset.type
FROM asset

You can add type-specific attributes to this query to read properties specific to assets such as ImageAsset or YoutubeVideoAsset.

For example, the following query lists the YouTube video IDs for all YoutubeVideoAsset objects in a Google Ads account by filtering the asset.type value. See a list of possible asset.type values.

SELECT
  asset.id,
  asset.name,
  asset.resource_name,
  asset.youtube_video_asset.youtube_video_id
FROM asset
WHERE asset.type = 'YOUTUBE_VIDEO'

Asset metrics

Asset metrics are made available through a few resources:

• ad_group_asset
• campaign_asset
• customer_asset

With these resources, you can query asset metrics at each respective level. For example, when you query the ad_group_asset resource, you can use the ad_group.id field to segment the results, thereby retrieving metrics for each unique combination of ad_group and asset:

SELECT
  ad_group.id,
  asset.id,
  metrics.clicks,
  metrics.impressions
FROM ad_group_asset
WHERE segments.date DURING LAST_MONTH
ORDER BY metrics.impressions DESC

Ad-level metrics

Key point: The ad_group_ad_asset_view only returns information for assets that are related to App ads, Demand Gen, and responsive search ads.

Ad-level performance metrics for assets are aggregated in the ad_group_ad_asset_view. This view collects metrics for assets per individual ad. Thus, querying this view returns one row per ad group and ad.

The ad_group_ad_asset_view exposes the view-specific attribute performance_label that gives insight into the performance characteristics of this specific asset-ad pairing. The following table enumerates the possible values of the performance_label fields.

The following GAQL query returns impressions, clicks, costs, and conversions for all assets in a Google Ads account during the last month, sorted by their performance_label:

SELECT
  ad_group_ad_asset_view.ad_group_ad,
  ad_group_ad_asset_view.asset,
  ad_group_ad_asset_view.field_type,
  ad_group_ad_asset_view.performance_label,
  metrics.impressions,
  metrics.clicks,
  metrics.cost_micros,
  metrics.conversions
FROM ad_group_ad_asset_view
WHERE segments.date DURING LAST_MONTH
ORDER BY ad_group_ad_asset_view.performance_label

Asset source

Asset.source is only accurate for mutable assets.

For the source of RSA assets use ad_group_ad_asset_view.source.
