Meta Removes Placement Exclusions From Ad Sets: What Breaks and What to Do

If you opened an ad set this week and could not find the familiar placement checkboxes, that is not a glitch. Since 25 August, advertisers have been reporting that manual placement selection has disappeared from the ad set level, replaced by value rules. The difference matters: a rule does not switch a placement off, it only makes it more expensive to win. Here is exactly what breaks in your account and what to do about it before peak season.

What actually changed

Until now every ad set carried a Placements block where you could untick Audience Network, Reels, in-stream comments or anything else. Those settings behaved as prohibitions: a disabled placement received no impressions at all.

Some accounts now see value rules in that block's place. The mechanic is different: you set a multiplier against your bid for a given placement, device or mobile operating system. The range runs from an eleven-fold increase down to a 90% reduction.

The status of the change is worth noting separately. Meta has published no announcement, its Business Help Centre still describes manual placement selection as available, and advertisers are seeing the block vanish selectively. It may still work the old way in your account while a colleague's account has already switched.

What to do right now

The sequence worth working through this week, before the season starts.

1. Check whether the change has reached you. Open any ad set and look for the placements block. If value rules sit there instead, you are on the new logic.
2. Write down what you excluded and why. Split it into two columns: brand safety prohibitions and efficiency-driven restrictions. Those are different jobs with different answers.
3. Move hard prohibitions to account level. Advertising Settings, then Account Controls, then Placement Controls. It is the one place where a block still behaves like a block. The downside is that it applies to the entire account rather than one campaign.
4. Convert efficiency exclusions into rules. If Audience Network was simply producing expensive leads, a -70% or -90% multiplier settles it as well as the checkbox did.
5. Review the placement breakdown for the last 30 days. It often turns out an exclusion has been running on inertia for years while the placement actually performs fine.
6. If the prohibition is critical and one account serves several brands, split the accounts. Account-level controls have no middle setting: they either apply to every campaign or to none.

Are placement exclusions even worth keeping

Since not everything needs migrating, it is worth checking which of your exclusions are actually justified. Below are the placements people argue about most, with an honest answer for each.

The headline conclusion from that table: most exclusions in older accounts were set three or four years ago on advice that has since expired. Before spending time migrating them, look at the placement breakdown and keep only what the numbers or the brand's own rules actually support.

If you are an agency or run several brands

Here the change creates a separate organisational problem. Account-level restrictions apply to every campaign inside the account, so the "one ad account for several clients" arrangement stops working the moment two clients have different placement requirements.

• Split accounts by brand. The most reliable option, even though it adds work in Business Manager.
• Put the change in writing. If a contract specified excluded placements, tell the client before they discover it themselves.
• Audit every account at once. The rollout is happening in waves, so some clients still have the block and others do not. Finding out mid-campaign is the worst case.

Why Meta is doing this

The reason is the same as behind every other change of the past two years: fewer manual constraints mean more room for the algorithm and better automated allocation. From the system's point of view, an excluded placement is a closed path to a cheap conversion.

Partly that is true. In many accounts placement exclusions genuinely raise costs: the audience stays the same while the inventory shrinks, so the auction gets denser. The problem is not the logic itself but the fact that brand safety and efficiency are different things, and one cannot be substituted for the other.

What not to do

• Do not apply -90% everywhere "just in case". Every such rule narrows the algorithm's room and raises cost per result across the remaining placements.
• Do not move exclusions to account level indiscriminately. It will also hit the campaigns where that placement was performing well.
• Do not wait for an official announcement. Meta regularly rolls changes out without one, and by the time the help pages catch up you will have been running under the new rules for weeks.
• Do not make sweeping edits right before peak season. Every significant change restarts learning, and in November the cost of that mistake is at its highest.

Frequently asked questions

My placements block is still there. How long will that last?

Unknown. The rollout is happening in waves with no published timeline. It is worth preparing your exclusion list now so you are not rebuilding it in a panic when the interface changes.

Can Audience Network still be blocked completely?

Not at ad set level any more. At account level, yes, through Placement Controls in Advertising Settings. It applies to every campaign in the account at once.

How much does -90% actually reduce impressions?

It depends on the auction. In cheap placements, even a 90% cut can leave your bid competitive and impressions will continue. The rule cannot deliver a guaranteed zero by design.

Does this affect Advantage+ campaigns?

Those never offered much manual placement control, so fully automated campaigns barely notice. The change lands hardest on classic manually configured campaigns.

What if a client demands a written guarantee about placements?

Explain honestly that the platform no longer offers that guarantee at ad set level, and move the restriction to account level. If the client genuinely needs isolated control, the reliable answer is a separate ad account for that brand.

This change looks minor, but it belongs to the category that surfaces at the worst possible moment: after the brand has already appeared somewhere it should not have, when the explanation has to be given retroactively.
