Facebook Is Removing Ad Format Selection — What It Means for Affiliates

Carousel, single image, video, collection — these distinctions are going away. The algorithm will decide for you. Here's what's changing and how to work with it.

What Happened

Facebook has started sending notifications inside Ads Manager: manual format selection is being removed. Where you used to choose between carousel, single image, video, or collection, that choice will no longer exist.

In its place comes a unified system: you upload your media, and Facebook decides which format to show each user on each placement. You can upload both images and video in a single ad, and the algorithm will pick the right combination for each impression.

How This Is Different from Before

Previously, buyers selected formats manually — carousel, photo, video, and collection were separate campaign types. Flexible Ads existed as an optional tool. Now it becomes the only standard: you upload media, and the algorithm decides what each user sees.

This is essentially the evolution of Flexible Ads, except it's no longer an option — it's the default way everything works.

Why Facebook Is Doing This

The platform is moving toward full automation of its ad inventory. The logic is straightforward: the algorithm processes billions of behavioral signals and knows whether to show someone a carousel or a vertical video. Unifying formats is the next step after Advantage+, automated placements, and automated bid optimization.

Facebook's goal is for advertisers to simply upload creatives and let the platform handle everything else. For large brands, that's convenient. For affiliates, it's not always the case.

Where the Problem Lies

Facebook optimizes for clicks and engagement — toward the metrics it has been trained on. Affiliates care about conversions. Those are not the same thing, and the algorithm doesn't know the difference.

If a carousel built from three specific creatives was converting well, Facebook may now show them in a different order, to a different audience segment, or in an entirely different format. You upload several images without knowing how the platform will combine them. The sequence that made sense in a carousel may lose its logic. Feed-only setups will also behave differently — controlling placement manually will be harder.

How to Adapt

Make every creative self-sufficient. Each asset should work on its own, without relying on the context of a carousel. If an image only makes sense alongside another one, that's a risk. Review each visual independently before launch.

Think through how your assets work together. Facebook may assemble a carousel from your images that you never intended. Sequence, conceptual consistency, visual flow — all of this now needs to be considered in advance.

Mix formats within a single ad. Upload both images and video and let the algorithm figure out what works best for different audience segments. That's exactly what the new system is designed to do.

Focus on conversion metrics, not CTR. The algorithm will optimize for clicks — keep an eye on what happens further down the funnel. Compare results before and after at the conversion level, not engagement.

Affiliates who held onto manual placements after Advantage+ launched eventually made the switch anyway. The same will happen with formats. The platform is moving in one direction — toward advertisers simply uploading assets and letting the algorithm handle the rest. Fighting it is pointless. The advantage goes to those who adapt their creative production sooner rather than later.
