The key to a successful content campaign is the ability to measure the results. You’ll have no real idea of how well or poorly your campaigns are doing if you can’t understand how it’s performing. You must know which key metrics you’re tracking and how to evaluate them to help you improve your content to maximize conversions.
Writing content without a plan is like building a house without a blueprint. You can come up with a stellar-looking wall that everyone loves, but it wouldn't do you any good without a foundation.
