As of my last update in September 2021, I can provide you with five legitimate ways that people were making money on Facebook. However, please note that the digital landscape evolves quickly, and the effectiveness of these methods might have changed since then. Always research and adapt to current trends and policies. Here are five ways people were making money on Facebook:


1. **Facebook Ads and Sponsored Posts**: If you have a sizable following or a popular Facebook page, businesses may pay you to promote their products or services through sponsored posts. Facebook's ad platform also allows you to create and run ads for other businesses.


2. **Facebook Marketplace and Buy/Sell Groups**: Utilize Facebook's marketplace to sell products, or join local buy/sell groups to buy and sell items to make a profit.


3. **Affiliate Marketing**: You can promote products from other companies and earn commissions on sales generated through your unique affiliate links. Be sure to comply with Facebook's advertising policies when using affiliate links.


4. **Facebook Live and Video Content**: Create engaging video content and use Facebook Live to interact with your audience. Once you build a significant following, you can monetize your content through ad revenue, sponsorships, or merchandise sales.


5. **Offering Services and Consulting**: If you have expertise in a specific field, you can use Facebook to promote your services and offer consulting or coaching to individuals or businesses.


Keep in mind that Facebook has specific policies and guidelines about commercial activities on its platform, so make sure you read and comply with their terms of service. Also, prioritize building genuine connections and providing value to your audience, as success on Facebook often relies on community engagement and trust.
