Optimization score and recommendations

Video: Deep dive

Recommendations can improve your campaigns in a few ways:

  • Introduce new and relevant features
  • Get more out of your budget with improved bids, keywords, and ads
  • Increase the overall performance and efficiency of your campaigns

To increase optimization scores, you can use the RecommendationService to retrieve recommendations, and then apply or dismiss them accordingly. You can also subscribe to automatically apply recommendations by using the RecommendationSubscriptionService.

Optimization score

Video: Optimization score

Optimization score is an estimate of how well your Google Ads account is set to perform and is available at the Customer and Campaign levels.

The Customer.optimization_score_weight is only available for non-manager accounts and is used to compute the overall optimization score of multiple accounts. Retrieve the optimization score and optimization score weight of the accounts and multiply them together (Customer.optimization_score * Customer.optimization_score_weight) to compute the overall optimization score.

There are optimization-related metrics available for customer and campaign reports:

  1. The metrics.optimization_score_url provides a deep link into the account to view information on the related recommendations in the Google Ads UI.
  2. The metrics.optimization_score_uplift tells how much the optimization score would increase if all related recommendations are applied. It's an estimate based on all available recommendations as a whole, not just the sum of the uplift scores for each recommendation.

To group and order the returned recommendations, you can segment both of these metrics by recommendation type using segments.recommendation_type in your query.

Retrieve recommendations

Video: Live coding

Like most other entities in the Google Ads API, Recommendation objects are fetched by using the GoogleAdsService.SearchStream with a Google Ads Query Language query.

For each type of recommendation, details are provided in a recommendation-specific field. For example, CAMPAIGN_BUDGET recommendation details are in the campaign_budget_recommendation field, and are wrapped in a CampaignBudgetRecommendation object.

Find all recommendation-specific fields in the recommendation union field.

Recommendation impact

Some recommendation types populate the impact field of the recommendation. RecommendationImpact contains an estimate of the impact on account performance as a result of applying the recommendation. The following recommendation metrics are available in the impact.base_metrics and impact.potential_metrics fields:

  • impressions

  • clicks

  • cost_micros

  • conversions

  • all_conversions

  • video_views

The following sample code retrieves all available and dismissed recommendations of type KEYWORD from an account and prints some of their details:

Take action

Any retrieved recommendation can be applied or dismissed.

Depending on the recommendation type, recommendations can change on a daily basis or even multiple times a day. When that happens, a recommendation object's resource_name can become obsolete after the recommendation is retrieved.

It is good practice to take action on recommendations shortly after retrieval.

Apply recommendations

Video: Apply recommendations

You can apply active or dismissed recommendations with the ApplyRecommendation method of the RecommendationService.

Recommendation types can have mandatory or optional parameters. Most recommendations come with recommended values that are used by default.

Setting accounts for auto-applying recommendations is not supported for all recommendation types. However, you can implement similar behavior for the recommendation types that are fully supported by the Google Ads API. Refer to the DetectAndApplyRecommendations code example to learn more.

Use the apply_parameters union field of ApplyRecommendationOperation to apply recommendations with specific parameter values. Each suitable recommendation type has its own field. Any recommendation type not listed in the apply_parameters field does not use these parameter values.

Code example

The following code demonstrates how to build the ApplyRecommendationOperation and how to override the recommended values if you want to replace them with your own.

Java

/** Creates and returns an ApplyRecommendationOperation to apply the given recommendation. */
private ApplyRecommendationOperation buildRecommendationOperation(Recommendation recommendation) {
  // If you have a recommendation ID instead of a resource name, you can create a resource name
  // like this:
  // String resourceName = ResourceNames.recommendation(customerId, recommendationId);

  // Creates a builder to construct the operation.
  Builder operationBuilder = ApplyRecommendationOperation.newBuilder();

  // Each recommendation type has optional parameters to override the recommended values. Below is
  // an example showing how to override a recommended ad when a TextAdRecommendation is applied.
  // operationBuilder.getTextAdBuilder().getAdBuilder().setResourceName("INSERT_AD_RESOURCE_NAME");

  // Sets the operation's resource name to the resource name of the recommendation to apply.
  operationBuilder.setResourceName(recommendation.getResourceName());
  return operationBuilder.build();
}
DetectAndApplyRecommendations.java

C#

private ApplyRecommendationOperation BuildApplyRecommendationOperation(
    string recommendationResourceName
)
{
    // If you have a recommendation_id instead of the resource_name you can create a
    // resource name from it like this:
    // string recommendationResourceName =
    //    ResourceNames.Recommendation(customerId, recommendationId)

    // Each recommendation type has optional parameters to override the recommended values.
    // This is an example to override a recommended ad when a TextAdRecommendation is
    // applied.

Automatically apply recommendations

You can use the RecommendationSubscriptionService to automatically apply recommendations of a specific type.

To subscribe to a particular recommendation type, create a RecommendationSubscription object, set the type field to one of the supported recommendation types, and set the status field to ENABLED.

Recommendations in campaign construction

You can use RecommendationService.GenerateRecommendationsRequest to generate recommendations during campaign construction, for a given set of recommendation types.

GenerateRecommendations accepts as input a customer ID, an advertising channel type which must be either SEARCH or PERFORMANCE_MAX, a list of recommendation types to generate, and various data points dependent on the specified types. It outputs a list of Recommendation objects based on the data you provide. If there isn't sufficient data to generate a recommendation for the requested recommendation_types, or if the campaign is already in the recommended state, the result set won't contain a recommendation for that type. Make sure your application handles the case where no recommendations are returned for the requested recommendation types.

The following table describes the recommendation types that GenerateRecommendations supports, and the fields you must provide to receive recommendations for that type. As a best practice, send the GenerateRecommendations request after all information has been collected related to the requested recommendation types. For additional details on required and optional fields, including nested fields, consult the reference documentation.

Example usage flow

Suppose your company is an advertising agency which provides a campaign construction workflow to users, and you want to offer suggestions to users during that flow. You can use GenerateRecommendationsRequest to generate recommendations on-demand, and incorporate those recommendations into your campaign construction user interface.

The usage flow might look like the following:

  1. A user comes to your application to create a Performance Max campaign.

  2. The user provides some initial information as part of the campaign construction flow. For example, they provide details to build a single SitelinkAsset, and they select TARGET_SPEND as their Smart Bidding strategy.

  3. You send a GenerateRecommendationsRequest which sets the following fields:

    • campaign_sitelink_count: set to 1, which is the number of sitelink assets on the work-in-progress campaign.

    • bidding_info: set the nested bidding_strategy_type field to TARGET_SPEND.

    • conversion_tracking_status: set to the ConversionTrackingStatus of this customer. For guidance on how to retrieve this field, visit the Getting started guide for conversion management.

    • recommendation_types: set to [SITELINK_ASSET, MAXIMIZE_CLICKS_OPT_IN].

    • advertising_channel_type: set to PERFORMANCE_MAX.

    • customer_id: set to the ID of the customer creating the campaign.

  4. You can take the recommendations in the GenerateRecommendationsResponse — in this case, a SitelinkAssetRecommendation and a MaximizeClicksOptInRecommendation —and suggest them to the user by displaying them within your campaign construction interface. If the user accepts a suggestion, you can then incorporate it into the campaign creation request once the user completes the campaign construction flow.
