My niche is automotive. We have the inventory feeding into the Meta Commerce Manager and then use Product Sets to separate the inventory into different categories. The Meta Ads then link to these product sets. A typical use case would be to have a cover image that is the latest incentives for X vehicle, then behind it, the specific inventory comes up via the link to the product set. This is a critical piece to our Meta Ads. Any ecommerce type of business would be able to leverage this feature as well.
