I've been working on this project part-time for about 2.5 years. Only a few hours a week.
I earn an average of $679 a month from selling digital products. Monthly traffic is around 9,000 users. I don't use advertising, my only income stream is my own products. I don't use any paid advertising to generate traffic either as my product pricing is low so it's difficult to get a decent ROI.
It's a difficult niche I think (mental health/wellbeing). How am I doing? I have no idea..
I was considering making everything free (I already give away a lot for free) and generating money from advertising. Or just stopping working on it and starting something new.
