Just as one can make money on YouTube by agreeing to let the company add ads at the beginning and pay you on the basis of viewership, Facebook has a similar model. A lot of small businesses have flourished by creating pages on Facebook and selling their products online. Not that this means creating a page for your goods on Facebook will increase sales from day one but you will have a higher viewership and a Facebook page is way easier managed than a website and is also free of cost. Even if you don’t sell a lot via Facebook, your presence on Facebook is important, it at least informs the people of your presence and the sort of products that you sell.
Besides, you may collaborate with Brands because Social media has become the best way to reach people and thus influence them. An influencer is basically anyone with a huge following and someone whose posts have high traction and can gather the attention of the online crowd. You can have a technology-related page or even have a page that focuses on being a book reviewer or an artist who has a huge follower base and collaborates with many brands to promote products. Brands love collaborating with good content creators and reaching their target audience in an indirect manner.
Another way of earning money with your Facebook page is to add links to affiliate products on your Facebook page and earn a commission when those products are purchased using your link. So whatever area you are writing or creating content on, you can add links and tabs to earn via affiliate marketing as well.
Moreover, you can sell Likes and shares since a lot of big brands prefer their posts to be liked and shared by people with high followers. Remember, here again, your viewers and followers define the worth of your likes and shares.
