Starting on July 5, 2023 we will gradually release a backend improvement on Google Ads keyword policy validation.
You might see an increase in keyword policy violation failures when you send Google Ads API  requests that create keyword criteria. The Google Ads API will catch more keywords that don’t adhere to our keyword policy as soon as you send the API request, rather than validating them offline after the keywords have been submitted.
Note that not all keywords created through successful API calls will be accepted. Keywords still undergo offline review.
Due to the new realtime check, you might need to account for new policy violation terms in the PolicyViolationDetails guide on keyword policy exemptions .
If you have any questions or concerns, please don't hesitate to contact us via the forum .
