Kirk Williams shared that starting March 19, 2025, Google Ads will automatically opt his account out of serving ads on parked domains.
This change means ads won’t appear on these low-value sites unless advertisers manually opt back in via Content Suitability settings.

First announced in September 2024, this update aims to improve ad placement quality. If you still want to run ads on parked domains, you must re-enable the settings in your account.
