This has been around for a long time, but the company has changed it up some recently. You can get paid on Sponsored Tweets to tweet, blog, take photos, and take videos. And you also are now able to connect multiple social media accounts to help ensure you get the most brand exposure (paid opportunities). You can go here to sign up and check it out.
Also, realize that people aren’t going on social media to buy things. Instead that want to be engaged or entertained and possibly learn something. With that being said, I’ve found out about a lot of great products and services via social media so if you do choose to promote affiliate products, realize that many of your followers probably won’t buy but the larger your following is, the more likely you are to make a sale.
This is probably the most direct way to make money off social media. You utilize your (hopefully sizable) list of followers by selling to companies the rights to promote their products or services as a post on your social media account. Check out this site to learn more. The chances of making a lot of money this way is high if your number of followers is in the six figures, but rather low if you have less than a thousand followers.
Thanks Mike for your comment. I don’t trust Facebook either. There’s been many times where I have seen ads come up on FB of subjects that I’ve been talking about offline. Its happened on more than one occasion which is a bit scary if you ask me. Although I do think FB has had its best days and will gradually fall in user numbers as new and innovative platforms come to market over the next 5 years.

If you use social media you need to engage with your customers, involve them in a dialogue, and ask them for their opinions. Post a picture of two items you are considering carrying in your store and ask customers which one they like best. This creates a dialogue which leads to shared posts which leads to engaged followers. Plus, if you follow this example, it will also lead to enhanced margins because your back and forth conversation will prevent you from buying the item that won't sell as well.
Just remember that it is always a good practice to add a disclosure about your affiliate links to your social media audience. This builds up a trust with them. Secondly, don’t spam your social media communities with affiliate links as this puts off the people. Always have a healthy ratio of generic informational posts (which are of interest to your audience) to the promotional posts (with your affiliate links).
If you ever find yourself in a bind, your advocates will help remind the rest of the world who they're rooting for. Advocacy is not something that you can stumble upon or buy. Advocacy is earned over time through continuous and positive engagement with your customer base. It is earned through experiences that delight, and through the delivery of the highest class of customer service.
A unique way to create revenue in collaboration with a brand is to co-create a physical product, collection or range. We see this type of influencer monetization across every niche, from fashion capsule collections and co-branded beauty products to food, fitness, travel and health products. A great example of this is makeup artist and beauty YouTuber Jaclyn Hill’s collaboration with cosmetics brand Becca.  
The variety of evolving stand-alone and built-in social media services makes it challenging to define them.[2] However, marketing and social media experts broadly agree that social media includes the following 13 types of social media: blogs, business networks, collaborative projects, enterprise social networks, forums, microblogs, photo sharing, products/services review, social bookmarking, social gaming, social networks, video sharing, and virtual worlds.[17]
