One ex-freelancer told me: "If I was ever light on promotion or marketing for one month, I wouldn't notice it at the time, but I would a couple of months later."

In crowded marketplaces, how can freelancers make the most of the opportunities that social media provides?

There are many opportunities available:

• Establishing more diverse, bigger networks
• Direct marketing to interested prospects
• Keeping up-to-date on industry stats and developments
• Promoting your own content - and curating other pieces of content - to become known as a trusted source of information.
