Google Ads API v23.1 adds text guidelines, YouTube video uploads, and frequency metrics
Google has released v23.1 of the Google Ads API with several notable features. Text guidelines support is now available for Performance Max and Search campaigns, allowing programmatic control of AI-generated text assets.
This update uses a PMC cover because no suitable source image was available when checked on 8 Sept 2026. Available source and video links are retained.
What changed
A new feature YouTubeVideoUploadService enables uploading and managing videos directly through the API. New frequency metrics (unique_users_two_plus through unique_users_ten_plus) report how many users saw your ad at least 2, 3, 4, 5, or 10 times. Additionally, YOUTUBE_FOLLOW_ON_VIEWS conversion tracking is now available to track users who watch an ad and later watch a video from the same channel.
Why it matters for advertisers
For you, this means API users can now automate brand safety controls and gain deeper frequency insights.
