Facebook Groups are good places for sharing, discussion and networking. They are also a gold mine where you get plenty of opportunities to earn revenue. For example, you can sell the stuff that may not be useful for you anymore but can help other people. For both sellers and buyers, it is a gain. You can propose your freelance service web design, SEO, mame, graphic design…carpooling, home service, babysitting, teaching… and get paid for your work. Write a short story to tell people what it is about and include a call-to-action to invite people to take a look. If group members like what you share, they may also share it in other groups or on their personal timeline. In this way, you can drive traffic to your blog or site, or get views for your videos to get paid. If you work for your customers and help them get traffic to their monet, YouTube Channels, Facebook pages and groups, then you can explain to them how you get visitors and targeted audience for them and get paid per post click.
