Once you've completed a detailed SWOT Analysis for your company, you should then be able to more clearly atriculate your competitive advantage.

What is a competitive advantage -- and why is it important?

• It defines the one thing that you do (that you provide) that is different or better than any of your competitors.
• Offering greater value to your customers than what your competition can offer.
• Competitive advantage can be price, but it is better to be benefits provided.
• You may have more than one competitive advantage, but its best to select just one or two (to keep it simple for your customers to understand)
• Once you identify your competitive advantage, you can claim your position in the market. Positioning is the image you create about your business for your prospective customers.
