I'm going to give you a 100% white-hat way of making money with Reddit.
The first thing that you need to do is you need to set up a mailing list that is tied to a domain.
On that domain, you're gonna promote your mailing list.
The mailing list should be clear as to the kind of information that you cover and how that information is going to benefit the people on your list.
Now once that is out of the way, you need to look at your niche and find subreddits where problems involving your niche are being talked about.
And then join as many subreddits as possible as long as they're within your niche.
Don't worry about the member count.
While it would be great if every single one of these subreddits has at least a thousand members, even if they have a few hundred, that's okay.
What's important is niche specificity.
The next thing is to participate in the discussions.
Offer real information.
You can also contribute value by asking questions that help people ask or start conversations to clarify what it is that they're after.
This way, you help the conversation long.
Whatever the case may be, you become an asset to these different communities because they know that you're not a drive-by spammer.
You're not just there to bullshit.
You're there to help people learn as you yourself learn.
And once you start sharing information, stuff that isn't published by you but by experts in the niche that you are promoting, people will start seeing that you're the real deal.
And then slowly, you start sharing your blog posts, and then your blog is the one that markets your mailing list.
You can also start sharing snippets of your past updates from your mailing list.
Pretty soon, people will want to join your mailing list, and you can then talk about it on your profile page.
When people click your profile, they can quickly figure out where your mailing list is.
In other words, you let your expertise do the marketing for you.
Don't start with the link to your mailing list.
Don't do that.
Invest some time first.
Build that credibility.
I know this scares a lot of people because this sounds like actual work and it is.
But the good news is that with certain types of work, the little that you put in scales up over time.
You can't do that with a typical 9–5 job.
