Brands that want to enter the social commerce space should first have a basic understanding of how it works on popular social channels. Facebook: Brands can use Facebook's social commerce functionality by setting up Shops through their company pages. When someone wants to buy something, they can browse on the page's Shop and pay directly through Facebook, without being redirected to your website. 

Pinterest: Pinterest has a blue price tag feature called a Buyable Pin, which allows shoppers to purchase anything they see on the site. Since Pinterest users are accustomed to interacting with product-driven images, the platform is conducive to having people purchase items when they find something they want to buy. Plus, these pins are easy to spot while browsing search results and on different boards. Brands can promote the pins, similarly to sponsored content on other social networking sites.

Instagram: Last November, the platform experimented with a new strategy: adding a shopping bag icon to posts to "tap to see more details from products featured in posts, and even click to a business's website if you're ready to buy." This makes it easier for the consumer to purchase products by redirecting them to a product listing from an external link. Business owners can also view insights from these buttons as well as for any sponsored ads they put out.
