Facebook Marketplace was launched in 2016 and is a platform to buy and sell products or services locally. Click on Marketplace on the left of your screen when logged in.
Based on your region, Facebook will display products that have been sold and those that are trending.
On the other hand, Facebook Shop is for a particular business or brand selling its products. For example, by clicking on the ‘Shop’ CTA on Fitbit’s homepage, the user is redirected to the products landing page on its website.
In addition, business can link their Facebook and Instagram Shops, list their products on the page, categorize them, and have the ‘add to cart’ and checkout options.
