Starting on March 3, 2025, the Google Ads API and Google Ads scripts search term insight reports will return all search subcategories as empty. The Google Ads UI already removed this field, and the API is also rolling out this change to be consistent across Google Ads.
What do I need to do?
Starting March 3, 2025, it is expected that all values for segments.search_subcategory
will be empty.
If you query segments.search_subcategory
in the campaign_search_term_insight
or customer_search_term_insight
reports, then:
Check that your code can handle an empty value in segments.search_subcategory
. An empty string already is a catch-all, so your code should be already handling this.
We recommend removing segments.search_subcategory
from your query.
If you have any questions or concerns, you can reach out to us through our support form .
