Once a product goes out of stock, the ads for that product get removed from the advertising catalog thanks to our real time product updates, so there’s no need to untag! 😀
If you're seeing an ad featuring a product that has recently gone out of stock, it's likely that you're seeing a cached ad, which is normal. It can take a little bit for the product update to make its way through the system.
Once the product is back in stock, we will automatically include the product in your advertising catalog so your customers can be retargeted with it.
