Meta is removing placement exclusions from ad sets. From late August 2026, advertisers in Sales and Leads campaigns started losing the ability to switch off individual placements, whole platforms, device types or mobile operating systems at the ad set level, and the official replacement, value rules, can turn a placement down by up to 90 percent but can never turn it off. The only true "off" switch left is the account-level placement control in Advertising Settings. If you run broad Advantage+ placements everywhere already, you barely notice. If you built Instagram-only, mobile-only or no-Audience-Network ad sets, you need to rebuild how those rules are enforced.
What Meta actually removed
The change showed up as an Ads Manager notice around 20 August 2026, first spotted by independent Meta ads analysts and then covered by Social Media Today. Meta has not published a big announcement or a firm completion date. It is rolling out as a phased test, and the reports so far put Sales and Leads objectives first.
Four ad set controls are going away:
- Individual placement exclusions. No more unticking Facebook right column, Reels in-stream or search results inside one ad set.
- Platform exclusions. You can't turn off Facebook to build an Instagram-only ad set, or the reverse.
- Device targeting. Mobile-only and desktop-only ad sets lose their switch.
- Operating system targeting. iOS-only and Android-only delivery at the ad set level is gone.
Separately, Messenger Stories was retired as a placement entirely on 27 August 2026. That one is simply finished — it's not a control you can rebuild.
The pattern matches everything Meta has done since Advantage+: remove the manual lever, then offer a weighting tool in its place. We wrote about the delivery side of that shift in our Andromeda ROAS recovery guide. This is the same move applied to placements.
Value rules: a dimmer, not a switch
Meta's answer is value rules. Per the Marketing API value rules documentation, a rule adjusts your bid based on criteria like age, gender, location, placement, device platform, mobile OS and audience labels. Increases run from 1 to 1,000 percent. Decreases run from 1 to 90 percent.
Read that last number again. Ninety percent is the floor. A placement you bid down by 90 percent is much less likely to win auctions, but it still enters them, and on a cheap placement a 10 percent bid can still win. Value rules shape where money goes. They don't guarantee where it doesn't go.
The limits matter more than the headline:
- Six rule sets per ad account, ten rules per set, four criteria per rule. Plenty for one brand. Tight for an agency account running a dozen offers with different placement needs.
- Only two bid strategies qualify. Value rules work with highest volume (lowest cost without a cap) and cost per result goal (cost cap). Bid cap and ROAS goal ad sets can't use them.
- Some conversion setups are excluded. Sales campaigns mixing web and in-store conversions, and lead campaigns mixing web and call conversions, can't attach value rules at all.
- There is no platform-level rule. You can bid down specific Facebook placements. You can't bid down "Facebook" as a whole.
That last point is the one that stings for service businesses. It's a common setup in local lead gen: an Instagram-only Stories and Reels ad set, built because Facebook feed leads came in cheaper per form but booked far fewer jobs once someone actually called them. Value rules can push Facebook feed down hard. They can't make that ad set Instagram-only again.
The one real off switch left: account-level placement controls
Account-level placement controls still work, and they're now the most important setting most advertisers have never opened.
Go to Advertising Settings in the ad account, find Placement Controls, turn on the option that your business only advertises on specific placements, and uncheck what you never want to buy. It applies to every campaign in the account.
There's a detail here that makes it stronger than the old ad set exclusion. Over the past year, excluding a placement inside a Sales or Leads ad set came with a checkbox, often on by default, that let Meta spend up to 5 percent of budget on each excluded placement "when it's likely to improve performance." Exclude four placements and up to 20 percent of the budget could still leak into them. The account-level control has no 5 percent allowance, so it is the only exclusion that actually means "never."
The catch is that it's account-wide. If one client in a shared account must never appear on Audience Network and another is fine with it, you've got two options: split them into separate ad accounts, or accept the stricter setting for both. For agencies running multiple brands under one ad account, this change quietly pushes you toward one ad account per brand. We think that's the right structure anyway.
Hard rules versus soft preferences
Before you touch anything, sort every exclusion you have into one of two buckets. This is the part most "what to do" articles skip, and it's the part that decides the replacement.
Hard rules are exclusions that exist for reasons performance can't override:
- Brand safety. A client in a regulated or sensitive category that can't appear next to Audience Network app inventory.
- Contract terms. A client agreement that specifies Instagram only, or no in-stream video.
- Creative fit. Assets that genuinely break in a placement, like a 1:1 static with critical copy that gets cropped in Reels.
Hard rules go to account-level placement controls. If the rule only applies to some campaigns, that's a signal to split the ad account.
Soft preferences are exclusions you added because a placement performed worse. Audience Network looked junky. Facebook right column never converted. Desktop leads were twice the cost.
Soft preferences become value rules. And honestly, a lot of them were never re-tested after they were set. Plenty of exclusions we find in audits have no note explaining them and predate the account's current pixel and Conversions API setup, so nobody knows whether the original reason still holds. This is a decent excuse to find out whether they still deserve the penalty.
How to set value rules without wrecking delivery
The instinct is to take every soft exclusion and set it to the maximum 90 percent decrease. Don't.
A 90 percent cut on a placement is close to an exclusion in practice, and you lose the one benefit of the new system: letting Meta test inventory you'd written off. Start around a 50 percent decrease on the weak placement, run it for two weeks, and read the placement breakdown. If spend share stays small and cost per result on that placement is still bad, push it to 75 or 90. If it's performing, you just found cheap inventory you were blocking.
Three things we check when setting these up:
- Your conversion signal has to be clean first. Value rules optimize toward whatever event you feed Meta. If your Conversions API setup is sending low-quality or duplicated leads, the system will happily buy more of them in the placements you just bid up. Our Conversions API setup guide covers the event quality side.
- Creative has to exist for every placement. If broad placements are now the default, an ad set with only a square image will serve cropped versions in Stories and Reels. Build 9:16 and 4:5 versions, which we go deeper on in our paid social creative guide.
- Lead forms need a quality gate. For lead gen, broader placements usually mean more volume and more junk. Higher-intent form settings and a qualifying question do more than a bid rule. Our Facebook lead ads guide for service businesses has the setup we use.
What to watch after the change reaches your account
Placement leakage is measurable, so measure it. Add the placement and device breakdowns to your weekly report and keep the export you made before the change. Compare three numbers per ad set: spend share by placement, cost per result by placement, and, if you have a CRM or Hyros feeding back booked or closed outcomes, the downstream quality by placement.
That last one is the real test. A placement that produces cheap form fills and no booked jobs will look great in Ads Manager and awful in revenue. Meta's reporting judges placements on the events you send it. Your CRM judges them on whether anyone paid.
Don't react to one week. Platform changes shake delivery for a week or two while the system re-learns, and the most common mistake we see is an agency reverting a structure on day six. Move a value rule only on a shift that holds for two consecutive weeks.
Our take
This is a small loss for advertisers who were already on Advantage+ placements, and a real loss for anyone who used placement exclusions as a precision tool. Meta's view is that its delivery system allocates better than your checkboxes. For most accounts with clean conversion data, that's probably true on average. It's not true for every client, and "on average" is cold comfort to the one whose brand-safety requirement just became a 90 percent bid reduction.
The practical answer is structure: hard rules at the account level, soft preferences as value rules, and a CRM feedback loop that tells you which placements actually make money.
Do this now: export your current placement setups, sort every exclusion into hard or soft, move the hard ones to account-level controls, and rebuild the soft ones as moderate value rules. Then report on placements weekly for a month.
If you'd rather have someone else untangle it, our ads management team does exactly this kind of restructure. Or start with a free automation audit — we'll map which of your ad sets depend on exclusions, what should move to account level, and whether your conversion data is clean enough for Meta's automation to deserve the extra control.
