The calculation
Pacing
Month-to-date Grant cost is divided by the current day and extended across the selected month. That projected cost is compared with the allocation equivalent in the account currency.
Screening bands
Zero delivery means no month-to-date cost. Material under-utilisation is below 25% projected, partial utilisation is 25% to 59.9%, and high utilisation is 60% or more. These are tool triage bands, not Google policy thresholds or account targets.
Constraint order
Policy and measurement signals come before demand, bidding and landing-page alignment. This prevents a higher spend figure from hiding a more important account problem.
Action selection
The first three checks follow the earliest reported constraints. They are investigation priorities, not performance guarantees or automatic account changes.
