Yes, your campaign showing “Not Eligible” on Black Friday—despite year-round eligibility—is likely triggered by a combination of Buy Box loss and catalog competition spikes.
During high-traffic events like Black Friday, competition intensifies dramatically. If your product loses the Buy Box, Amazon or other platforms (like Walmart or Meta Shops) may mark your ad as ineligible—even if you were eligible before. Most ad platforms only allow Buy Box owners to advertise, especially in dynamic auction environments.
Another possibility is catalog overload. During sales events, the system often prioritizes top-performing or better-priced listings for limited ad inventory. If your listing’s performance (CTR, conversion rate, pricing, or ratings) drops compared to others, the algorithm may suppress visibility to maintain ad efficiency.
Additional triggers include:
Pricing parity issues across marketplaces
Policy changes on catalog quality or variant grouping
Delayed synchronization between inventory updates and ad eligibility
What You Can Do:
Regain the Buy Box by optimizing price, shipping, and fulfillment
Check retail readiness metrics (reviews, stock, pricing)
Audit ad diagnostics in Seller Central or Business Manager
Contact support for clarity—they can confirm if suppression is Buy Box-related or technical
To avoid recurrence, monitor eligibility daily during peak periods and set up alerts when Buy Box is lost or ad status changes.
In short, yes—limited Buy Box ownership or catalog competition likely caused your Black Friday ineligibility.
