• A. Analyzing data and drawing insights from it
• B. Creating hypotheses without data
• C. Copying competitors' strategies
• D. Focusing only on creative assets

Answer: (A)

Analyzing data and drawing insights from it is essential to decision-making in digital advertising. When you measure performance—think metrics like impressions, clicks, conversions, cost per action, and return on ad spend—you uncover what’s actually driving results and what isn’t. This foundation lets you test ideas, run controlled experiments, and attribute changes in outcomes to specific actions such as creative changes, audience targeting, or bid adjustments. A data-driven approach helps you allocate budget where it delivers the most impact, optimize campaigns in real time, and continuously improve ROI rather than guessing. Relying on hypotheses without data leaves you vulnerable to bias and misinterpretation; copying competitors ignores your unique audience and measurement context; and focusing only on creative assets overlooks how targeting, bidding, and the overall measurement framework shape results.
