As a marketer, in what way should you evaluate your campaign?

The most effective way to evaluate a campaign is by comparing its results against specific, predefined objectives. If a campaign's performance exceeds its goals (e.g., higher conversion rates, lower cost-per-acquisition than targeted), it's successful. If it falls short, adjustments are needed. Focusing solely on worst-performing ads without considering overall objectives is too narrow and might miss the bigger picture. Checking budget usage alone doesn't indicate campaign effectiveness; a campaign could spend its entire budget without achieving its goals. While lifetime value analysis and brand lift are valuable metrics, they are often part of broader, long-term strategic evaluations, not the primary method for immediate campaign performance assessment against specific objectives.
