Enjoy sitting at the shite end of the Pareto income distribution.

OF is a marketing gig, if you don't have a way to push your content and leverage network effects, you're not going to make any money.

The revenue from an only fans is the customer count × avg customer lifetime × avg subscription price, customer count is a function of your exposure to potential customers, and lifetime is a function of your content frequency and originality (I assume if you upload the same content types the fan base gets bored).

So, if you want a successful OF, you need to first focus on exposure, but the algos on most social media reward the haves, so your first issue is getting into people's feeds. The best way to do this is targeting niches, areas with lower volume or high demand for content.

Then you need to keep your audience by engaging with them but pushing new concepts, which will present it's own challenges. There's very much a quick copy culture on these networks that you'll probably have to emulate to keep on the front of the engagement curve, and expect anything you do that success to be quickly replicated ad infinitum until it doesn't anymore. I think this is a losing battle over time.

You can also offer whale services like "girlfriend experiences" to try and lock in big spenders, but first you need them on a hook.

It's not just snap some pics and you're good.

You'll need a school full of students and probably some news sites to run an article about you in order to make those kinds of profits.
