What optimization strategy would be best to use if a line item has high performance and high delivery?
- Consider pausing the line item
- Maintain bids and frequency caps
- Remove additional supply
Explanation: The correct answer is **Maintain bids and frequency caps** because when a line item has high performance and high delivery, it indicates that the campaign is effectively reaching and engaging the target audience, driving strong results. In such a case, maintaining the current bids and frequency caps is the best strategy to sustain the successful performance. By leaving the bids unchanged, you continue to capture the same valuable audience while keeping the frequency caps intact to avoid overexposure. This approach allows you to maintain the balance of performance and delivery without risking overspending or diminishing returns. Pausing the line item or removing additional supply would limit the campaign’s reach and potentially reduce its effectiveness.
