An advertiser is running a Conversions campaign with narrow targeting and custom bidding. The campaign is not spending as much as it should, so what should the advertiser do to fix the issue?

When a Conversions campaign is struggling to spend its budget, it is usually because the combination of narrow targeting and a custom bid is making the ad uncompetitive in the Pinterest auction. Shift to automatic bidding: This is the most effective way to fix delivery issues. Automatic bidding allows Pinterest’s algorithm to adjust your bids in real-time to ensure you are winning enough auctions to spend your daily budget. It removes the guesswork of setting a "custom" price that might be too low to reach your narrow audience.
