Creating a Shopping Campaign

The first step in implementing Shopping Ads is to create a Shopping campaign. Shopping campaigns allow users to see Ads that show an image of the product including title, price, store name and more. When creating a Shopping campaign, you will need to set its budget, bidding strategy and the shopping settings.

Before you can create a Shopping campaign, you need to link your Google Ads account to your Google Merchant Center account. Consult the article on linking your accounts for more information. Once you have linked accounts, you can use the Google Merchant Center account ID when specifying the shopping settings.

There are two types of Shopping campaign that can be created using the Google Ads API:

Standard Shopping campaigns
Smart Shopping campaigns

Different campaign settings are required to support these types of campaign, which are covered below.

Standard Shopping campaigns

This is the campaign required to create Product Shopping ads. Product Shopping ads allow you to include an image, title, price, and your store or business name inside your ads, without the need for you to create unique ads for each product you sell.

Here are the steps for setting up a standard Shopping campaign:

Set the campaign's advertising_channel_type to SHOPPING.
Create a ShoppingSetting, set the fields and then add it to the campaign.
Create a portfolio bid strategy or set a campaign level bid strategy.
Create a new campaign budget or set an existing shared budget.

For standard Shopping campaigns, ShoppingSetting supports the following fields:

Required

merchant_id: The Merchant Center ID of the account that contains the products to advertise.
sales_country: The target sales country of the products to include in this campaign.
campaign_priority: The priority of the shopping campaign. Campaigns with numerically higher priorities take precedence over those with lower priorities. Allowed values are between 0 and 2, inclusive.

Optional

enable_local: The option to enable ads for products sold in local stores for this campaign.

A bid strategy can be set up as a:

Portfolio bid strategy: An automated bid strategy that can be shared across campaigns, ad groups and keywords. Created using the BiddingStrategyService.
Campaign bid strategy: A bid strategy set directly on the campaign. This can include automated bidding strategies compatible with Shopping campaigns.

For standard Shopping campaigns, the following bid strategies are supported:

Portfolio bid strategy

Campaign bid strategy

This code example demonstrates how to create a standard Shopping campaign.

Smart Shopping campaigns

This is the campaign required to configure Smart Shopping ads. A Smart Shopping campaign combines standard Shopping and display remarketing campaigns, and uses automated bidding and ad placement to promote your products and business across networks.

Here are the steps in setting up a Smart Shopping campaign:

Setting the campaign's advertising_channel_type to SHOPPING.
Setting the campaign's advertising_channel_sub_type to SHOPPING_SMART_ADS.
Create a ShoppingSetting, setting the merchant_id and sales_country then adding it to the campaign.
Set a campaign level bid strategy.
Create a new campaign budget (only non-shared budgets).

For Smart Shopping campaigns, ShoppingSetting supports the following fields:

Required

merchant_id: The Merchant Center ID of the account that contains the products to advertise.
sales_country: The target sales country of the products to include in this campaign.

Optional

campaign_priority: The priority of the shopping campaign. Campaigns with numerically higher priorities take precedence over those with lower priorities. This field is optional for Smart Shopping campaigns, but must be equal to 3 if set.
enable_local: The option to enable ads for products sold in local stores for this campaign.

A bid strategy can be set up as a:

Campaign bid strategy: A bid strategy set directly on the campaign. This can include automated bidding strategies compatible with Smart Shopping campaigns.

For Smart Shopping campaigns, the following bid strategy is supported:

Campaign bid strategy

maximize_conversion_value

A ROAS target can be optionally set for maximize_conversion_value. This can be set using the target_roas field on MaximizeConversionValue. For more information on maximize conversion value, see the support article: About maximize conversion value bidding.

These steps are demonstrated in the following code:
