Google has updated the Auto optimize feature in AdSense to give publishers more control and flexibility:
Site-level control: You can now enable or disable Auto optimize per individual site.
New location: Auto optimize settings are now managed from the Ads page, not the Experiments page.
Simplified options: “Suggestions only” is now a checkbox labeled “Auto-apply experiment winner”, letting you choose if Google should apply winning experiments automatically.
Clearer overview: A new Auto optimize column on the Ads page shows which sites have it enabled.
Default for new sites: Newly added sites will have Auto optimize turned on by default, with “Auto-apply experiment winner” selected, 50% traffic split, and no blocked experiments but you can change this anytime.
These changes are rolling out in the coming weeks, and your current settings will carry over automatically.
