Report and optimize

Key Point: Since v17 of the Google Ads API, all Demand Gen-related entities have been renamed from discovery to demand_gen. If you are using v16, Demand Gen is still referred to as "Discovery" in the Google Ads API.

Reporting information for Demand Gen campaigns can be retrieved at different levels, similar to other campaign types.

Campaign-level reporting

As with other campaign types, you can use GoogleAdsService.SearchStream to retrieve attributes and performance metrics for Demand Gen campaigns.

With Google Ads API v17 and later:

SELECT
  campaign.id,
  campaign.status,
  campaign.bidding_strategy_type
FROM campaign
WHERE campaign.advertising_channel_type = DEMAND_GEN

With Google Ads API v16:

SELECT
  campaign.id,
  campaign.status,
  campaign.bidding_strategy_type
FROM campaign
WHERE campaign.advertising_channel_type = DISCOVERY

To retrieve clicks in reporting for Demand Gen campaigns, filter by click_type of CROSS_NETWORK.

Ad-level reporting

There are three types of Demand Gen ads supported by the Google Ads API. Use these queries with GoogleAdsService.SearchStream to retrieve them.

With Google Ads API v17 and later:
