A Consideration campaign has been running for three weeks and is meeting goals, but under pacing. The campaign uses custom bids, multiple broad ad groups targeting women users, aged 18-24, and broad match keywords. What can the advertiser do to ensure the campaign delivers in full?

The term "underpacing" means the campaign is not spending its allocated daily budget. When a campaign is meeting its performance goals (like a good Cost Per Click) but failing to spend, the custom bid is likely acting as a "ceiling" that prevents the ad from winning enough auctions. Automatic Bidding: By switching to automatic bidding, you allow Pinterest to bid dynamically on your behalf. The system’s primary objective changes to spending your full budget while finding the lowest cost results. This is the most direct solution for underpacing issues.
