Diagnose a campaign that cannot spend its budget
Identify whether delivery is limited by eligibility, bids, or demand.
The scenario
A niche business-to-business campaign spends only $35 of its planned $120 daily budget.
If ads are eligible and search volume is low, higher bids may buy only a few more impressions. Expanding from exact product names to related problem terms changes the audience and warrants its own budget.
Apply it to your own work
Check disapprovals and billing first, then geography, scheduling, search demand, and bid constraints. Expand one constraint at a time and label any new traffic segment.
What to watch for
Increasing a campaign cap is useful only if the cap is the binding constraint. Avoid interpreting underspend alone as a platform error.
Separate a launch issue from a ceiling
Build a delivery log with eligibility, bid settings, daily demand, and last change. If the campaign has no eligible impressions, check account and targeting restrictions before adjusting bids. If it wins most eligible impressions and still underspends, demand is more likely the ceiling.
Set a small separate budget for any expansion. A new audience can improve delivery and still miss the original conversion goal. Compare its cost and quality on its own terms before moving spend from the original campaign.
