Bidding & Pacing
Programmatic bidding and pacing
Understand how bidding goals, budget limits and pacing settings work together, and what to check when spend or campaign outcomes drift.
Bidding decides which eligible impressions a campaign tries to buy and at what price. Pacing governs how quickly its budget is used. Set both against the campaign outcome, flight and spending limits, then review delivery and results together.
A campaign can spend on schedule while missing its goal, or achieve a useful result while leaving budget unused.
Give each control a job
A bidding goal tells the buying platform what to favour within the inventory it can access. Depending on the line item, that might be clicks, conversions or a view. A demanding cost-per-outcome target can cause the bidder to pass up opportunities and underspend. Prioritising budget delivery gives the bidder more flexibility, but does not make every purchase valuable.
Pacing sets a spending pattern. In Display & Video 360, Even pacing aims for a consistent pattern when supply is steady; Ahead pacing aims to run faster than an even flight target; ASAP aims to use an available allocation quickly. These settings cannot guarantee a daily spend amount.
| Decision | Question to settle | Evidence to review |
|---|---|---|
| Bid goal | Which measurable outcome is closest to the campaign objective? | Outcome volume, cost and quality |
| Bid constraint | How much delivery may be traded for efficiency? | Spend, eligible opportunities and auction losses |
| Pacing | How much budget should remain for later in the flight? | Spend to date, days remaining and daily pattern |
| Budget level | Which setting limits the combined line items? | Saved insertion-order and line-item settings |
Read platform pacing targets as limits
In Display & Video 360, insertion-order and line-item pacing settings work together as caps: delivery follows whichever cap is lower. If a line item reaches its daily cap, it stops serving for that day even when the insertion order still has room; the insertion order cap applies the same way.
For flight pacing, Ahead aims to spend up to 120% of the prorated daily target, updated in real time. Flight Even divides the remaining flight budget by the days remaining at the insertion-order level; a line-item Flight Even target also accounts for serving hours per day. These targets describe intended distribution, not a promise of available impressions.
Pacing Strategies in Display & Video 360: Key Differences
- Even PacingConsistent daily spend based on remaining flight budget divided by days left. Suitable when supply is steady.
- ASAP PacingUses available budget as quickly as possible. Best for campaigns needing rapid delivery.
Check the budget hierarchy
In Display & Video 360, an insertion-order budget can restrict the combined spend of its line items. The insertion order caps their combined spend at its own limit, even if the line items’ daily targets add up to more. Check both levels before treating a quiet line item as a bid problem.
Record what the authorised budget includes. Display & Video 360 monetary budgets use total cost under the partner revenue model, not media cost alone. Use a consistent cost definition when comparing the plan with reports. Name the reporting time zone and currency so Australian teams working across daily cut-offs compare the same period.
How Budget Hierarchy Works in Display & Video 360
- Set Insertion Order BudgetDefines the total spend cap for all line items under it.
- Assign Line Item BudgetsEach line item has its own daily or total budget, but cannot exceed the insertion order cap.
- Monitor Combined SpendActual spend across line items is capped at the insertion order level, even if individual line items have higher targets.
Keep budget types aligned
An insertion order and its line items must use the same budget type in Display & Video 360: a monetary insertion-order budget cannot contain line items budgeted by impression count. Budgets can be expressed as money to spend or impressions to buy, so confirm the chosen unit matches the campaign’s authorised limit before comparing delivery with the plan.
Make the trade-off explicit
For an outcome-led campaign, choose a measurable goal and a target the team can defend. Monitor whether the bidder finds enough opportunities at that target. For a fixed-date delivery commitment, agree how far an efficiency target may be relaxed, if at all. A switch to a spend-first strategy changes the decision being optimised.
For a reach or exposure brief, use a relevant delivery measure rather than treating clicks as proof that people noticed the message.
Even pacing can be a starting point when supply is fairly steady. Ahead pacing may reduce the risk of a late shortfall, but can use money before a later opportunity. ASAP suits a deliberate need to buy quickly. None overrides eligibility, auction competition or a restrictive bidding goal.
Trade-offs of Outcome-Led vs Spend-First Bidding Goals
- Outcome-Led BiddingPros: Targets meaningful results (e.g., conversions). Cons: May underspend if targets are too strict.
- Spend-First BiddingPros: Maximises budget usage. Cons: May sacrifice efficiency; not all purchases are valuable.
Review spend and results together
Compare actual spend with the amount needed per remaining day, then put the campaign outcome beside it. Display & Video 360 shows today’s spend, historical daily average and a remaining-flight daily target in its pacing view.
If spend falls behind, locate the constraint before changing a setting. Display & Video 360’s Troubleshooter can show why a deal is not spending, why impression availability was lost, and why a line item is not winning available inventory. More detailed data may take longer to become available, and native creatives are not supported.
Record each material change, its reason and its expected effect on both spend and results. If the eligible pool remains too small, revise the spending expectation or seek approval for a wider brief. A faster pacing setting cannot manufacture suitable opportunities.

Use forecasts as planning signals
Display & Video 360’s line-item spend forecast simulates delivery using historical bid requests that match the current targeting, bid, budget and flight settings. The historical period is based on the flight length, up to 30 days into the future; the forecast changes as line-item settings change.
Treat a forecast as an estimate, not a delivery guarantee. The platform may indicate that underspend risk is high, low or cannot be determined; high-risk forecasts can include suggestions about creative, bids or targeting. Forecasts are available only for specified YouTube and display line-item types, and overlapping targeting is not included in the calculation.
