Meta's Ad Tools Can Add Website Discounts to Copied Ads Even With Promotions Turned Off

The behaviour matters most for businesses running several offers at once, as many will be in the run-up to Black Friday on November 27 and Cyber Monday on November 30. A discount intended for one campaign or one group of customers could appear in an unrelated ad, and Meta is changing its terms so that advertisers carry responsibility for what its AI features add to their ads.

Bram Van der Hallen, a Meta advertising specialist at the agency Edge.be, described the issue in a LinkedIn post on November 6. Meta "may now automatically detect offers from your website and use them in your Meta ads," he wrote, adding that this could happen even when the option had been turned off for the original ad.

The control sits in Commerce Manager, under an "Offer merchandising" settings page, PPC Land reported. A block labelled "All ads" contains a "Detected offers" checkbox that applies across an advertiser's ads, and a second block for ads leading to a shop or product browsing has boxes for sale events and seasonal event names. All three were ticked in the account Van der Hallen showed. When an ad is duplicated, Meta displays a notice that reads: "Eligible promotions can appear with your new ad, even though promotions are turned off for your original ad."

Van der Hallen said advertisers can stop the practice by changing the Commerce Manager settings so that detected offers are not used in other campaigns. Several basic questions remain unanswered. PPC Land said it could not establish whether the boxes are ticked by default, when the feature began, which countries it covers, whether every advertiser sees the settings page or only those with a shop or product catalogue, and whether an ad already running with promotions off can also pick up a detected offer. Meta has made no public statement about the feature, and neither PPC Land nor Social Media Today, which also covered the findings, included a response from the company.

The discovery adds to a series of changes that hand Meta's systems more control over ad content. PPC Land reported on October 22 that Meta's revised Commercial Terms add an "AI Features" section making advertisers solely responsible for what Meta's AI features create or change in their ads, including features Meta switches on itself. The terms were due to take effect on October 30, but on October 23 Meta moved the effective date to November 20, without saying it would change the wording. It is not clear whether an automatically inserted offer would fall under that section.

Separately, product browsing was switched on from October 28 for existing ads whose owners did not opt out. Meta has been promoting the results of its automated ad tools: it credited ad ranking improvements with an increase of more than 8% in ad clicks and a 15.7% uplift in conversions on Facebook in the second quarter of 2026, according to Social Media Today.

For merchants, the practical step before the holiday sales is to check the offer merchandising settings in Commerce Manager. Nirar Punj, a paid media specialist, responded to Van der Hallen's post: "I'm checking the offer merchandising settings in Commerce Manager on my accounts now." Meta's revised terms take effect on November 20.
