Having a community means there are people paying attention to something you provide.
A community starts to exist when people share an interest, recognize your judgment and come back because they find something useful, close or hard to get elsewhere.
If that community is healthy, participates, asks questions, recommends you, waits for your content or returns for more, there is a real opportunity to generate revenue. It may be large or small at first; what matters is starting with an offer you can sustain and improve.
If you are still clarifying what you could sell exactly, this guide on how to sell your knowledge online can help first.
To monetize a community, identify what members need and define what they receive in return for payment. State the content, access, duration and price.
