Fetching Asset Attributes and Metrics

Reading asset attributes

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.

The following GAQL query lists all assets in an advertiser’s account along with their resource name and type.

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

Note that there are type-specific attributes that you could add to the above query to read properties specific to, say, ImageAsset or YoutubeVideoAsset. For example, the query below lists the YouTube video IDs for all YoutubeVideoAsset objects in an account by filtering the asset.type value (see the documentation for a list of possible type values) for YoutubeVideoAsset.

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

Fetching ad-level metrics

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 a row per ad group and ad.

Key Point: The ad_group_ad_asset_view only returns information of assets that are related to App ads.

Note: The ad_group_ad_asset_view exposes a view-specific attribute called performance_label that gives insight into the performance characteristics of this specific asset-ad pairing. The possible values of the performance_label fields are enumerated below.

performance_label	Description
BEST	Best performing assets.
GOOD	Good performing assets.
LOW	Worst performing assets.
LEARNING	The asset has started getting impressions but the stats are not statistically significant enough to get an asset performance label.
PENDING	This asset does not yet have any performance information. This may be because it is still under review.
UNKNOWN	Represents value unknown in this version.
UNSPECIFIED	Not specified.

The GAQL query below, for example, would return impressions, clicks, costs, and conversions for all assets in an 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
