Get keyword theme, budget, and ad text asset suggestions

The Google Ads API exposes the SmartCampaignSuggestService to suggest configuration details when creating Smart campaigns. It uses details about the business being advertised (in the form of a SmartCampaignSuggestionInfo instance) to suggest keyword themes, a budget amount, as well as headlines and descriptions for the individual ads.

Create a SmartCampaignSuggestionInfo instance

Generating Smart campaign suggestions requires the use of a SmartCampaignSuggestionInfo instance that contains details about the business being advertised. Since it's possible to use the same SmartCampaignSuggestionInfo instance to retrieve all different types of Smart campaign suggestions, you can first create one and reuse it multiple times.

Key requirements for SmartCampaignSuggestionInfo:

  • A landing page is required, which can be either an existing website (final_url) or an automatic landing page created for your campaign using Business Profile information obtained with the business_profile_location identifier. If you plan to use an automatic landing page, be sure to set the business_profile_location field when generating suggestions.

    • If final_url is set, then either business_profile_location or business_name can be set.
    • If final_url is not set, then business_profile_location must be set.
  • When used to retrieve keyword theme suggestions from the SuggestKeywordThemes method, it's not necessary to set the keyword_themes field.

  • When used to retrieve ad suggestions from the SuggestSmartCampaignAd method, the language_code, and keyword_themes fields are required.

  • As many details as possible should be added to the object for optimal suggestions.

Build a list of keyword themes

A keyword theme is a single word or phrase that represents a group of related search terms. For example "bakery" is related to "bakery near me" and "local bakery." They are represented in the Google Ads API by the KeywordTheme resource, which is usually attached to a KeywordThemeInfo instance, and can either be a KeywordThemeConstant or a free-form keyword theme.

Suggested keyword themes

Given a SmartCampaignSuggestionInfo instance, the SuggestKeywordThemes service method suggests keyword themes using the details of your business, its location, and website content.

To fully optimize the performance of your Smart campaign, use the SuggestKeywordThemes method when creating keyword themes. Since it aggregates specific details about the business and its website, it generates significantly better keyword themes than the other two strategies, which are best considered as back-up options.

Java

    GoogleAdsClient googleAdsClient,
    long customerId,
    SmartCampaignSuggestionInfo suggestionInfo) {
  // Creates the service client.

This method should only be used if the SuggestKeywordThemes method can't be used or returns insufficient suggestions.

Free-form keyword themes

Lastly, free-form keyword themes can be created manually by setting the free_form_keyword_theme field on a KeywordThemeInfo instance.

Using free-form keyword themes is typically not recommended since they're less effective than suggested keyword themes. However, they are useful in situations where a very specific term needs to be targeted, or when you want to negatively target a term.

The SuggestKeywordThemes method might suggest free-form keyword themes, but only if you provide a final_url in the request.

Java

if (freeFormKeywordText != null) {
  keywordThemeInfos.add(
      KeywordThemeInfo.newBuilder().setFreeFormKeywordTheme(freeFormKeywordText).build());
}
      

C#

suggestionInfo.KeywordThemes.Add(keywordThemeInfos);
      

PHP

// Optionally includes any free-form keywords in verbatim.
if (!empty($freeFormKeywordText)) {
    $keywordThemeInfos[] =
        new KeywordThemeInfo(['free_form_keyword_theme' => $freeFormKeywordText]);
}
      

Python

def get_free_form_keyword_theme_info(client, free_form_keyword_text):
    """Creates a KeywordThemeInfo using the given free-form keyword text.

    Args:
        client: an initialized GoogleAdsClient instance.
        free_form_keyword_text: a keyword used to create a free-form keyword
          theme.

    """
    info = client.get_type("KeywordThemeInfo")
    info.free_form_keyword_theme = free_form_keyword_text
    return info
      

Ruby

def get_freeform_keyword_theme_info(client, free_form_keyword_text)
  client.resource.keyword_theme_info do |kti|
    kti.free_form_keyword_theme = free_form_keyword_text
  end
end

# Creates a KeywordInfo instance using the given free-form keyword text.
sub _get_free_form_keyword_theme_info {
  my ($free_form_keyword_text) = @_;

  return Google::Ads::GoogleAds::V16::Common::KeywordThemeInfo->new({
    freeFormKeywordTheme => $free_form_keyword_text
  });
}
      

These two strategies should be applied such that each of the different types of keyword themes gets attached to a KeywordThemeInfo instance:

Get suggested budget amount

The SmartCampaignSuggestService has a SuggestSmartCampaignBudgetOptions method that suggests three tiers of daily budget options when given a set of keyword themes and business details. The tiers are low, high, and recommended, and each option also includes an estimated minimum and maximum number of daily clicks.

Get suggested ad text assets

The SmartCampaignSuggestService has a SuggestSmartCampaignAd method that returns a SmartCampaignAdInfo instance with suggestions for up to three headlines and two descriptions for your Smart campaign ad. Each headline and description is contained in the field of an AdTextAsset instance attached to the SmartCampaignAdInfo.

This method might return no suggestions, or the AdTextAsset instances that are returned might have an empty string as their text field value. We recommend that you review these suggestions before they're used to create ads in order to ensure that ads are always created with the minimum of 3 headlines and 2 descriptions. If this minimum is not met, or if either asset text is too short, the request will fail with an error.

Suggestions for ad assets are largely derived from website content, so if a final_url is not specified on the SmartCampaignSuggestionInfo instance, suggestions are generated solely from the keyword themes provided in the request.

Java

private SmartCampaignAdInfo getAdSuggestions(
    GoogleAdsClient googleAdsClient,
    long customerId,
    SmartCampaignSuggestionInfo suggestionInfo) {
  // Unlike the SuggestSmartCampaignBudgetOptions method, it's only possible to use
