How to Use the Channel Focus vs Diversify Calculator
Deciding whether to concentrate marketing spend on one channel or spread it across several requires weighing expected return alongside risk, not return alone. This calculator divides each strategy's expected ROAS by its volatility (risk) to produce a risk-adjusted return, then compares the two strategies directly.
At the same expected return, lower volatility produces a higher risk-adjusted return, and a higher ratio signals a more risk-efficient strategy. Single-channel focus strategies often show a higher expected ROAS, but performance can swing heavily if that channel's algorithm or policy changes, which tends to push volatility up as well.
Multichannel diversification often has a lower expected ROAS per channel, but risk tends to offset across channels, lowering overall volatility. Keep in mind that diversification also requires more management resources since you're running and optimizing multiple channels at once.
Frequently Asked Questions
It's expected return divided by volatility (risk). At the same expected return, lower volatility produces a higher ratio, and a higher ratio means a more risk-efficient strategy.
Generally, yes. Relying on a single channel means an algorithm or policy change on that channel can swing performance heavily. That said, a focus strategy is simpler to manage and lets you build deep expertise in one channel.
