There’s many options of course, but this is how my system should look like:
1 a website that explains who I am, what I do and why and links to my other online real estate
2 a mailing list through which I keep in touch with my followers
3 a patreon account where people can follow me and support through subscription
4 a blog on which I regularly write about my topics
5 products and services: ebooks, video series, affiliate products, consults
6 instagram account
7 advertising system
8 landing pages
9 a funding page
All these assets need to be set up so that they support each other maximally. Skills like SEO and data analytics are needed skills to control this system.
If this system runs and the content in it is valuable for the target audience, it generates several income streams.
