Open one of your ad sets. Scroll down to Placements. Count the boxes you are still allowed to uncheck.

For some accounts, that number is heading to zero.

The notice nobody got a date for

On August 20, media buyer Jon Loomer published a message appearing inside the Placements section of ad sets for some advertisers. It read: "Excluding placements, platforms, devices and operating systems will no longer be available for your ad sets."

By August 21, the reporting was that Meta was removing ad-set-level placement exclusion controls entirely, meaning advertisers can no longer exclude individual placements — Facebook Search, Audience Network, Instagram Explore — from individual ad sets. The test began on Sales and Leads objectives, which is exactly where most coaches live.

Worth flagging honestly: Meta has published no announcement, and its own Business Help Centre pages still describe manual placement selection as available. No timeline has been announced. This is a rollout being mapped by practitioners, not a press release.

Your brand-safety exclusion becomes a discount

What replaces the checkbox is a value rule. Value rules let you bid up or down by placement, device and mobile OS, with bid cuts capped at 90%.

That cap is the whole story. A value rule does not remove a placement from delivery; it prices it differently. Exclusion is binary. A value rule is a dial, and the dial stops at 90%, not 100%.

So if you switched off Audience Network two years ago because the leads were garbage, that exclusion is about to turn into a discount. Meta will still buy there. Just cheaper.

Meta also tells you the bill up front. The value-rule setup screen carries a warning advertisers must confirm before proceeding: "your overall cost per result may increase when using value rules."

And the timing is unkind. Placement control moved from a hard exclusion to a bid nudge at the same moment the device breakdown stopped returning data by default — less control, and less visibility into the thing you no longer control.

The label you did not apply

Now the second half. In a June 1, 2026 update, Meta said it would begin automatically detecting ads created or edited using third-party AI tools through industry-standard signals, and apply an "AI info" label when detected. Meta said it uses detection methods such as C2PA to identify third-party generative AI in ad content.

Meaning: the coach does not decide whether the audience is told AI was involved. The metadata does.

Here is why media buyers flinched. The NYU Stern and Emory working paper on visual generative AI found fully AI-created ads increased click-through by up to 19% in field settings — and that disclosing AI involvement reduced advertising effectiveness by up to 31.5%. In the field study, the label cut click-through by about 1.17 percentage points against unlabeled human ads.

The machine made the better ad. Saying so made it worse.

The IAB leaned on exactly that number in version 2 of its AI Transparency and Disclosure Framework, published August 18, arguing for risk-based labeling rather than a blanket rule.

Do not overread the 31.5%

That figure came from a lab experiment and a field study on the Google Display Network, with an explicit label on the creative. It is not a Meta number.

Placement matters enormously. The feed-level label has a narrower confirmed rule — Meta places AI info beside "Sponsored" when its own advertiser tools generate a photorealistic human — and there is no published universal CTR penalty. Third-party detection mostly lands inside About this ad, behind the three-dot menu.

A disclosure most people never open is not a 31.5% haircut. But a generated face beside the word Sponsored is a different ad than the one you approved.

Four things to do this week

Export your placement data now, while you can still see it, and enable the three breakdowns that went opt-in.

Build the value rules before the checkboxes go. Rebuild your Sales and Leads placement exclusions as value rules now, ahead of a date Meta has not given.

Find your account-level controls. Account-level placement controls sit under Advertising Settings → Account Controls and apply to every campaign, not per ad set. Blunt, but binary.

Open your own ad as a stranger would. Three-dot menu. Look for AI info. Preserve provenance and measure label performance instead of repeating unsupported claims.

One more piece of context for anyone still running the same targets they set in January: average price per ad rose 12% year over year in Q2 2026, with impressions up 14%, per Meta's own results release. The room got more expensive while the light switches were being removed.
