Hopefully you’re using an analytics suite like Google Analytics to track your efforts. The information you get from these statistics enable you to make decisions, change your methods and better target your revenue sources. What most people don’t do however, is use their analytics to improve their marketing calendar strategy.
Let’s take Halloween for example. You’ve used Google Trends (among other ways) to figure out when your marketing should begin, you’ve used your keyword research tool to figure out what to write about, and you’ve used the AdWords Contextual Targeting Tool to help figure out how to structure your internal linking.
And then you’ve got Google Analytics (and to some degree WebmasterTools) to help you assess your progress. Well if you stop there, you’re only using half your resources. What you learn in your analytics package is how you begin putting together your marketing calendar in the first place. (it’s like a vicious circle)
