There are a few ways to advertise on Facebook for free. One way is to create a Facebook ad campaign and use the budget you set to $0. This will allow your ad to be shown to a limited number of people, but it’s a good way to start experimenting with Facebook advertising.
Another way to advertise for free on Facebook is to use the power of organic reach. This means creating content that is interesting and engaging enough to be shared by your followers, and then promoted by Facebook’s algorithm.
A third way to advertise for free on Facebook is to use the paid advertising features of Facebook’s Power Editor. This allows you to target your ads more specifically, and to use more advanced features like conversion tracking.
