Yes, You Can Find Freelance Writing Gigs Without Job Boards

Rather than passively looking for gigs, reach out to prospects you want to work with:

• Search on Google the keyword “(Your niche) brands)” or “(Your niche) companies)” to find a list of companies within your writing niche.
• Head to each website and write a few things you like about the company, like a webpage or blog post you enjoyed — What makes their content unique? Why do you enjoy reading it?
• You might want to check out their social media as well. Give them a follow and interact with their posts — the goal is to get in front of their radar.

Freelance writing communities are the spot for: 

• Asking for feedback 
• Sharing gigs you can’t take on 
• Holding each other accountable.

The easiest way to connect with writers is via Facebook groups. You can also join indie hackers, a platform for creators, and join their "freelancing" group. When you join a group, go to make friends rather than finding clients.
