Today, a business has many ways to find their audience

Today, a business has many ways to find their audience and gather so  much more information than was ever before thought possible. However, I  meet many small business clients for my marketing consulting business  who tell me that “Adwords doesn’t work” after spending a lot of money on  campaigns with poor results. Why do you think that there is such a  disconnect when Google gives you so much free information to help you  create and monitor your campaign to achieve success? Are there 'human'  issues that prevent people from fully using Adwords to its full  potential? How can you avoid those yourself?
