The percentage of times your ad didn't show on the Search Network due to insufficient budget.
Impression share lost (budget) estimates how much visibility you missed because your budget was too low. It doesn’t mean you should always increase spend - it means the campaign couldn’t enter every eligible auction.
If lost budget is high on a profitable campaign, it’s often one of the simplest levers for growth - assuming tracking is correct and capacity exists.
