Meta AI Is Auto-Adding Unapproved Discounts to Your Facebook and Instagram Ads

On November 7, 2026, Meta advertising practitioners flagged a significant default setting in Commerce Manager: Meta is automatically detecting discount offers from advertisers' websites and displaying them inside Facebook and Instagram ads, including on duplicate ads where promotions had been explicitly turned off. For ecommerce brands running multiple promotions simultaneously, this means a discount intended for one campaign or audience segment can appear in unrelated ads without manual intervention.

What Does Meta's Automatic Offer Merchandising Mean for Your Campaigns?

Meta's "Detected offers" setting in Commerce Manager pulls live discount data from your website and surfaces it inside active ads, regardless of whether individual ads have promotions enabled. The critical issue is that this setting is controlled at the Commerce Manager level, not at the ad level. Turning promotions off on a specific ad does not stop Meta from pulling detected offers into a duplicate of that ad. For brands running percentage-off promotions, clearance events, or tiered discounts, this creates a risk of unintended offer exposure across campaigns.

The setting is located in Commerce Manager under Settings, then Offer merchandising, in a checkbox labeled "Detected offers." Meta's own interface language confirms the behavior: "Eligible promotions can appear with your new ad, even though promotions are turned off for your original ad." This is not a bug. It is a default feature that Meta applies at the account level unless explicitly disabled.

How Is Meta's AI Finding and Adding These Discounts to Your Ads?

Meta's system scans your connected website or catalog for active promotional pricing and applies that data to ads it identifies as eligible. The mechanism is part of Meta's broader Advantage+ Creative suite, which uses AI to automatically enhance ad content based on data signals it can access. For ecommerce brands running Meta campaigns with active promotional pages, this means any publicly accessible discount code, sale price, or promotional landing page is potentially a data source Meta will use to populate ad offers.

This is distinct from the existing Advantage+ Creative text overlay and image enhancement features that have been rolling out through 2026. The Detected offers setting specifically concerns promotional pricing data, not creative formatting.

What Is the Risk for Ecommerce Brands Running Multiple Active Promotions?

The highest-risk scenario is a brand running concurrent promotions with different discount depths for different audiences. If Commerce Manager's Detected offers setting is enabled, Meta may detect a 40% off clearance promotion from one landing page and surface it inside a full-price brand campaign that is targeting a different audience segment. The result is that shoppers outside the intended clearance audience see a discount they were not supposed to, compressing margin on campaigns where you were not offering that promotion.

For 7- and 8-figure brands running structured promotional calendars with audience segmentation, this is not a minor UI issue. It is a default behavior that can erode promotional strategy if left unmanaged. The fix is straightforward, but it requires knowing the setting exists in the first place, which is why this update matters for every brand using Commerce Manager.

What Should You Do Now with Meta's Detected Offers Setting?

1. Go to Commerce Manager immediately and check the setting. Navigate to Commerce Manager, then Settings, then Offer merchandising. Find the "Detected offers" checkbox. If it is enabled and you have multiple active promotions, disable it today.
2. Audit your currently running campaigns. Review active ads in Ads Manager to see if any are displaying offer badges or promotional pricing you did not explicitly configure. If you find unexpected offers appearing, this setting is the likely source.
3. Review all duplicate ads created in the past 30 days. Meta's interface warning specifically mentions duplicated ads. Any ad you have copied or duplicated while this setting was active may have inherited or acquired promotional overlays from your website.
4. Establish a Commerce Manager settings review as part of your campaign launch checklist. This is at least the third Commerce Manager setting in 2026 that has had material impact on campaign behavior without a formal Meta announcement. Add Commerce Manager settings audits to your standard pre-launch process.
5. If you want selective offer surfacing, re-enable selectively. If you want Meta to surface specific promotions on specific campaigns, disable the global Detected offers setting and configure promotions individually at the campaign or ad level instead, where you have explicit control.
