Create campaign criteria

  • Campaign criteria for Smart campaigns are created using KeywordThemeConstant objects retrieved from the KeywordThemeConstantService.

  • Smart campaigns support specific criterion types including AD_SCHEDULE, KEYWORD_THEME, LOCATION, and PROXIMITY.

  • For location targeting, you can use multiple location criteria but only one proximity criterion, and you cannot use both simultaneously.

  • Negative keyword theme criteria in Smart campaigns must use a free-form keyword theme and behave like a negative phrase match keyword.

In Get suggestions, we demonstrated how to retrieve a set of KeywordThemeConstant objects using a word or phrase. In this step, we use those same keyword theme constants to create a set of CampaignCriterion objects for the Smart campaign to target.

Similar to how we used the budget amount suggested by the SmartCampaignSuggestService when creating a budget, we recommend that you create campaign criteria based on the keyword theme constants retrieved from the KeywordThemeConstantService in Get suggestions.

Here are the key requirements for Smart campaign criteria:

In the following example, the keyword theme constants have been converted to KeywordThemeInfo objects by setting their resource name onto the KeywordThemeInfo.keyword_theme_constant field. We set the campaign field using the temporary resource name set on the campaign in the previous step.
