Meta has made one of the most significant structural changes to its ads platform in years: the removal of manual ad placement exclusions at the ad set level. Advertisers who previously excluded specific placements — like Audience Network, In-Stream Video, or Marketplace — from individual ad sets can no longer do so. Instead, Meta is replacing that control with a system of bid reduction value rules and a new Exclusion-Only Custom Audiences feature.
The change, which began rolling out in August 2026, is now fully live for all Meta Ads Manager accounts globally. According to reporting from Admake AI and Bootcamp Digital, the removal was triggered by Meta's internal data showing that manual placement exclusions were causing campaigns to underperform by limiting the algorithm's optimisation surface area.
🔑 Key Takeaways
- Manual placement exclusions at the ad set level are now removed from Meta Ads Manager
- Replacement system: bid reduction value rules (up to 90% bid reduction for specific placements)
- New feature: Exclusion-Only Custom Audiences — suppress specific audience segments from seeing specific placements
- Meta CPM increased +13.24% YoY in Q2 2026 — $15.06 average, up from $13.30 in Q2 2025
- Campaigns that previously excluded Audience Network may now see higher costs if that exclusion was driving efficiency
- GCC advertisers should audit all campaigns immediately and set up bid reduction rules where needed
The Old System vs. The New System
| Feature | Old System (Before Aug 2026) | New System (Now) |
|---|---|---|
| Placement exclusions | ✅ Manual exclusion toggles per placement at ad set level | ❌ No manual exclusions — all placements eligible by default |
| Cost control for specific placements | Exclude placement entirely | Bid reduction rules (reduce bid by up to 90% for specific placements) |
| Audience suppression | Custom audience exclusions at ad set level | New Exclusion-Only Custom Audiences feature |
| Algorithm optimisation surface | Limited by manual exclusions | Broader — Meta AI optimises across all placements |
| Brand safety control | High — explicit placement blocking | Medium — dependent on bid rules and inventory filters |
Why Meta Made This Change
Meta's official position, stated in its Ads Manager update announcement, is that removing placement exclusions improves campaign performance by giving Meta's Advantage+ AI system a broader optimisation surface. When advertisers manually exclude placements, they are essentially overriding the algorithm's decisions about where conversions are most likely to occur — and Meta's own data showed this was frequently counterproductive.
Independent performance data from advertiser communities supports the principle, though with important caveats: campaigns running Advantage+ Placements (now the only option) with no manual restrictions do show higher conversion volumes in many cases. However, the CPM increases that accompany broader placement eligibility can offset conversion gains — particularly for advertisers who had specifically excluded Audience Network (which historically showed lower intent signals) to protect cost efficiency.

How to Use the New Bid Reduction Rules
The bid reduction value rule system works differently from placement exclusion but can achieve a similar outcome when configured correctly:
- Navigate to Ads Manager → Campaigns → Ad Sets → Bid Strategy → Add Bid Control Rule
- Select the placement you want to de-prioritise (e.g. Audience Network, Messenger Stories, In-Stream Video)
- Set a bid reduction value between 10% and 90%. A 90% reduction means Meta will only spend on that placement if the estimated bid needed is less than 10% of your normal bid — effectively excluding it in most auction scenarios
- Stack rules if needed — you can set different reduction percentages for multiple placements in a single ad set
🇦🇪 Immediate Action for UAE & GCC Advertisers
If your campaigns had placement exclusions set before August 2026, those settings have been removed. Your campaigns are now running across all eligible placements by default — including Audience Network and placements you may have previously avoided. Log into Ads Manager now, review your active campaign placements, and set up bid reduction rules for any placements you want to de-prioritise. This is especially urgent for brand-safety-sensitive advertisers in regulated sectors.
Understanding Exclusion-Only Custom Audiences
The second major change accompanying placement exclusion removal is the introduction of Exclusion-Only Custom Audiences. This feature allows advertisers to create audience segments that are used exclusively for suppression — meaning you can prevent specific groups of users from seeing your ads on specific placements, even without the old placement toggle system.
Use cases for this feature include: suppressing existing customers from prospecting campaigns on Audience Network while still reaching them on Feed; excluding high-churn audience segments from specific ad formats; and preventing overlap between retargeting and prospecting audiences on Instagram Stories.
While this feature partially compensates for the loss of manual placement controls, the granularity is different — it operates at the audience level rather than the placement level, requiring more upfront audience setup work.
