Google Similar Audiences
Another Google Ads upgrade, affecting comparable audiences targeting, is the result of the continuous focus on consumer privacy.
Google will phase out similar audiences targeting in 2023, according to Google Ads Liaison Ginny Marvin, who made the announcement recently on her Twitter account.
In August 2023, the second phase of sunsetting similar audiences will begin. Any current similar audience segments will be eliminated by Google from all ad groups and campaigns.
