Which of the following is NOT a standard lever you can pull to optimize a campaign mid-flight? Select the best answer.

Adjusting upvotes is not a standard optimization lever because upvotes are a user-driven metric reflecting community engagement, not a setting advertisers can directly control or manipulate within the Reddit Ads platform. While high upvotes can indicate successful creative, advertisers cannot "adjust" them. The other options are all standard optimization levers. Adjusting targeting allows you to refine your audience. Adjusting creative involves changing the ad copy, image, or video to improve performance. Adjusting budgets allows you to increase or decrease spending to scale or constrain campaign reach.
