One of the main drawbacks of freelancing, in general, is that you may need to spend a lot of time finding work, which leaves less time to actually make money. But that’s not usually the case with freelance writing.
Ideally, the posts on your blog will cover the same types of topics or the same industries that you pursue as a freelance writer. When you apply for gigs or reach out to people about writing for them, you can include links to a few articles on your blog that show your writing.
Let them know that you’re working as a freelance writer and list the topics that you cover or industries that you work in, and ask them to let you know if they have any contacts that might be in need of your services.
