What’s a realistic ROI expectation for different marketing channels?
ROI expectations vary significantly by channel and industry. Generally, I recommend targeting 3:1 ROI as a minimum, with top-performing channels achieving 5:1 or higher. Email marketing often delivers 4-7:1, while paid search typically ranges from 2-4:1. The key is understanding your specific business model and customer acquisition costs to set realistic benchmarks.
How often should I calculate and review ROI metrics?
I recommend real-time monitoring with formal reviews monthly and quarterly. Daily tracking helps identify trends quickly, while monthly reviews allow for tactical adjustments. Quarterly analysis is perfect for strategic planning and budget reallocation. The key is having systems in place that make measurement automatic, not manual.
