To serve ads for your standard Shopping campaign, you must create at least one
[`AdGroup`](https://developers.google.com/google-ads/api/reference/rpc/v26/AdGroup.md.txt).

## Overview

Standard Shopping campaigns support the [`SHOPPING_PRODUCT_ADS`](https://developers.google.com/google-ads/api/reference/rpc/v26/AdGroupTypeEnum.AdGroupType.md.txt#shopping_product_ads) ad group
type. This is the default ad group type for Shopping campaigns, serving standard
product ads. Set this by providing the ad group [`type`](https://developers.google.com/google-ads/api/reference/rpc/v26/AdGroup.md.txt#type) field when creating
the ad group.

Standard Shopping campaigns can contain multiple ad groups, each containing at
least one ad.

> [!NOTE]
> **Note:** You must have an existing standard Shopping campaign linked to a Google Merchant Center account before creating an ad group.

## Code example

The following code creates an ad group for a standard Shopping campaign and sets
a CPC bid to match the campaign's [`ManualCpc`](https://developers.google.com/google-ads/api/reference/rpc/v26/ManualCpc.md.txt) bidding strategy:


### Java

```java
private String addShoppingProductAdGroup(
    GoogleAdsClient googleAdsClient, long customerId, String campaignResourceName) {
  // Creates an ad group.
  AdGroup adGroup =
      AdGroup.newBuilder()
          .setName("Earth to Mars Cruises #" + getPrintableDateTime())
          .setCampaign(campaignResourceName)
          // Sets the ad group type to SHOPPING_PRODUCT_ADS. This is the only value possible for
          // ad groups that contain shopping product ads.
          .setType(AdGroupType.SHOPPING_PRODUCT_ADS)
          .setCpcBidMicros(1_000_000L)
          .setStatus(AdGroupStatus.ENABLED)
          .build();

  // Creates an ad group operation.
  AdGroupOperation operation = AdGroupOperation.newBuilder().setCreate(adGroup).build();

  // Issues a mutate request to add an ad group.
  try (AdGroupServiceClient adGroupServiceClient =
      googleAdsClient.getLatestVersion().createAdGroupServiceClient()) {
    MutateAdGroupResult mutateAdGroupResult =
        adGroupServiceClient
            .mutateAdGroups(Long.toString(customerId), Collections.singletonList(operation))
            .getResults(0);
    System.out.printf(
        "Added a product shopping ad group with resource name: '%s'%n",
        mutateAdGroupResult.getResourceName());
    return mutateAdGroupResult.getResourceName();
  }
}

      
```

### C#

```c#
private string AddProductShoppingAdGroup(GoogleAdsClient client, long customerId,
            string campaignResourceName)
{
    // Get the AdGroupService.
    AdGroupServiceClient adGroupService = client.GetService(Services.V26.AdGroupService);

    // Creates an ad group.
    AdGroup adGroup = new AdGroup()
    {
        Name = "Earth to Mars Cruises #" + ExampleUtilities.GetRandomString(),
        Campaign = campaignResourceName,
        // Sets the ad group type to SHOPPING_PRODUCT_ADS. This is the only value possible
        // for ad groups that contain shopping product ads.
        Type = AdGroupType.ShoppingProductAds,
        CpcBidMicros = 1_000_000L,
        Status = AdGroupStatus.Enabled
    };

    // Creates an ad group operation.
    AdGroupOperation operation = new AdGroupOperation()
    {
        Create = adGroup
    };

    // Issues a mutate request to add an ad group.
    MutateAdGroupResult mutateAdGroupResult =
        adGroupService
            .MutateAdGroups(customerId.ToString(), new AdGroupOperation[] { operation })
            .Results[0];
    Console.WriteLine("Added a product shopping ad group with resource name: '{0}'.",
        mutateAdGroupResult.ResourceName);
    return mutateAdGroupResult.ResourceName;
}
      
```

## Next steps

- After creating an ad group, [create a Shopping ad group ad](https://developers.google.com/google-ads/api/docs/shopping-ads/create-ad-group-ad.md.txt) and set up your [Shopping listing groups](https://developers.google.com/google-ads/api/docs/shopping-ads/create-listing-groups.md.txt) (product partitions) to define which products from your Merchant Center feed to target.
