Most marketers today would agree that it is reckless and risky to make decisions without data and research to guide and influence that decision. Modern marketers are willing to dig through data to find answers to critical questions. If the data isn't available (conversion rate, cost-per-conversion, engagement rates, customer lifetime value, multi-touch attribution, funnel/pipeline, etc.), a savvy marketing professional will work tirelessly to figure out how to get the data.
