If you were living on the east coast of the US, and wanted to drive to a small town on the west coast, would you just get in your car and start driving without a mapped out route???
Of course not. The same applies to business, and especially your social media strategy. You may already possess all the tools (in the example above, a car, gas, etc….in social media, a facebook page, twitter account, blog, email newsletter, etc), but without a carefully planned and implemented strategy, you will definitely get lost along the way.
