Question: You may need to adjust your bids depending on the performance of your bid optimization strategy. Which of the following bid adjustments should you consider?
- Identify keywords and products with higher conversion rate and increase their bids
- Identify the keyword and products with higher viewable cost per mille (vCPM) and decrease bids
- Identify the keyword and products with lower ACOS and decrease bids
Explanation
Higher conversion rate indicates that specific keywords or products are turning ad traffic into purchases more effectively. Increasing bids for these stronger performers can help secure more competitive placements and increase traffic from high-intent shoppers. This bid adjustment supports performance growth because spend is directed toward targets with proven conversion efficiency. It should be monitored with sales and cost metrics to maintain profitable delivery.
Why the other options are incorrect
Higher viewable cost per mille relates to viewable impression cost, not the strongest signal for increasing conversion-focused bids.
Lower ACOS indicates cost efficiency, so decreasing bids may reduce delivery for targets that are performing well.
