A product catalog is basically just an overview of your products in a format that Facebook can read and understand. But it's handy to have
When you as a private person share a picture of people on Facebook, you have the option to tag them so people can see who's who and view their profile. You also have this option with products if your webshop has a page on Facebook and you have uploaded your product catalog so that Facebook can identify your products.
It's all about Facebook knowing the name, price and URL of your product. Then you can tag the product and Facebook can link directly to it from Facebook and Instagram. This is an immediate advantage for you, your customers and, in theory, Facebook. It's conceivable that Facebook will eventually introduce some measures that will make it more expensive for you to advertise/promote your products via this channel, but for now it's a user-friendly solution that you should take advantage of.
Once you have created a product catalog, you can, for example, create a video with some of the products and tag them in the video. Facebook will then show your products right underneath. Nice for you and user-friendly for your customers.
You can get a product catalog on Facebook very quickly. You just need a feed and here you can use your Google Shopping feed. Of course, it comes with your Shoporama shop without you having to buy extra. Here you will find a guide on how to create your product catalog from your feed.
