Build your own blog, market it (I'm doing it now). I think the important thing is to build trust and help people. The important thing is SEO, and there are people who are really expert at it (not me though
![Sad](https://bitcointalk.org/Smileys/default/sad.gif)
).
Website flipping (again, SEO skill needed).
Invest in a well established website. Maybe you can buy a website for ~5000$ that get 500$/month with potential growth. Check Flippa and stuff (but don't get scammed).
Freelance (writing, programming, design). Nowadays, you can learn programming online with some motivation ! Writing is a little saturated but still possible.
You can check Pat Flynn's website. He seems very honest and he made a killing at doing business online.
http://www.smartpassiveincome.com/I've heard some people are freelancing + outsourcing. Like you have a skill in programming, ok but you don't have time for the next contract. You can outsource the thing to Bangladesh and still make a profit (you'll need to review the code and supervise).
Oh I forget the "dropshipping" thing, the games "reskinning" as well. I think that's all I know.
