How do I market my staffing agency?

You really have to understand your own brand strategy. If you don't understand your brand strategy, you're less than a commodity, because you won't be able to differentiate yourself from the competition. To figure out your brand, talk about your story. Why did you create this agency? What are your attributes in your benefits? How does your clients benefit functionally? How do they benefit emotionally? And who exactly are your clients? What problem is it that you're trying to solve? When you have all that written down in a clear and concise fashion, you'll be able to start to market yourself to those clients.
