You're reviewing your campaign set-up using the pre-optimization checklist. Which of the following steps should you complete as part of the checklist?

Confirming correct campaign budget allocation is a crucial step in pre-optimization. An insufficient or incorrectly distributed budget can severely limit campaign reach and performance, regardless of other settings. Ensuring the budget aligns with your advertising goals and expected spend is fundamental for effective campaign execution. Checking for correct on-Amazon.com conversions associated with the order is not a standard pre-optimization checklist item for campaign setup. Conversion tracking is typically set up at a broader account or product level, and while important for post-launch analysis, it's not a direct campaign setup configuration that needs to be verified before launch in the same way budget is.
