The best strategy would be to find a niche in the field. For example, Jonathan Wold made over $5,000 a month by building websites with WordPress and doing small theme customizations. You’ll probably be able to earn more if you offer the right kind of services to the right clients.

4. Content Marketing/Writing

Thanks to the boom in online marketing trends and the development of new methodologies, like Inbound Marketing, content writing is now considered as one of hottest fields for freelancers.

You don’t need to go anywhere to find proof of how well freelance writers are doing. Take me for example. Right now, I make around $5,000 a month (at least in most months) doing blogging work for businesses, writing, and content marketing work. And I know there are other freelance writers who do much better than me.
