Meta released a couple of updates for catalog-based ads in Ads Manager. The first one requires careful consideration before using it.
Product set expansion (my name) When setting up a product set, there's now an option to let Meta advertise products not included in the set (these are supposedly shown less often than your default products). Meta says this could help lower the cost per result… However, if we’ve specifically chosen to promote certain products, and the ad text is written for that group, I think I’ll keep this setting OFF in most cases.
Dynamic Media: If your catalog contains videos of products, turning this ON lets Meta decide whether to show images or videos in the ads. A similar option also exists under the Advantage+ creative enhancements, which seems odd, and I guess Meta might address that. As we’ve discussed before, adding videos to Meta catalogs can be tricky, but if available, I’d recommend using this feature. Note: Once this feature is enabled, clicking the Edit button reveals more options: "Automatic video cropping" and "Always show videos" (the latter only appears if you're using the single image format). These were OFF by default for me, but it’s worth checking just in case.
