Analyzing budget shifts based on campaign performance

A company has three marketing channels with the following monthly returns on ad spend (ROAS): Channel A: 4.0, Channel B: 1.5, Channel C: 0.8. If the total budget is $10,000, which allocation best reflects a data-driven approach?

A $3,000 to Channel A, $4,000 to Channel B, $3,000 to Channel C

B $5,000 to Channel A, $3,000 to Channel B, $2,000 to Channel C

C $7,000 to Channel A, $2,000 to Channel B, $1,000 to Channel C

D $4,000 to Channel A, $4,000 to Channel B, $2,000 to Channel C

💡 Hint

Higher ROAS means better returns, so allocate more budget there.

Channel A has the highest ROAS, so it should get the largest share of the budget to maximize returns.

Identifying risks in data-driven budget allocation

Which of the following is a potential risk when relying solely on historical data for budget allocation?

A Ignoring emerging channels that have no past data but high potential

B Using data to reduce waste and improve campaign efficiency

C Ensuring budget is always spent evenly across all channels

D Increasing budget for channels with proven high returns

💡 Hint

Think about what might be missed if only past data is considered.

Relying only on past data can cause marketers to overlook new channels that might perform well but lack historical data.

Optimizing budget allocation with diminishing returns

A digital marketing team notices that increasing budget on Channel X improves sales but with diminishing returns after $5,000. How should they adjust their budget allocation if the total budget is $12,000 and Channel Y has steady returns?

A Allocate all $12,000 to Channel X since it has higher returns initially

B Allocate $5,000 to Channel X and $7,000 to Channel Y to maximize overall returns

C Allocate $10,000 to Channel X and $2,000 to Channel Y to focus on the best channel

D Split the budget evenly: $6,000 to Channel X and $6,000 to Channel Y

💡 Hint

Consider how diminishing returns affect the value of extra budget on Channel X.

Because returns diminish after $5,000 on Channel X, it's better to allocate the remaining budget to Channel Y which has steady returns, maximizing total sales.
