Jake noticed his Reddit campaign has low impressions and is underspending. What should he consider changing to improve his spending and delivery? Select all that apply.

Low impressions and underspending often indicate that the campaign isn't reaching enough of its target audience or isn't competitive enough in the auction. Expanding targeting allows the campaign to reach a broader, yet still relevant, audience, which can increase impression opportunities and spending. Increasing bids makes the campaign more competitive in the ad auction, improving its chances of winning impressions and delivering ads. Pausing the campaign would halt spending entirely, worsening the problem. Doubling or tripling budgets without addressing targeting or bid issues won't necessarily lead to more delivery; the campaign still needs to be able to win impressions.
