DV360 Cheat Sheet: Campaign Setup, Targeting, Bidding & Optimization

Display & Video 360 (DV360) is Google's demand-side platform (DSP) that helps advertisers and agencies plan, manage, optimize, and measure programmatic advertising campaigns across eligible digital inventory.

DV360 supports programmatic media buying through campaign management, audience targeting, creative management, bidding, inventory selection, and performance reporting. It is widely used by programmatic specialists, media buyers, campaign managers, and ad operations professionals.

This DV360 cheat sheet covers the platform's structure, insertion orders, line items, targeting, bidding, creatives, pacing, reporting, and troubleshooting workflows.

1. What Is DV360?

Display & Video 360 is part of Google Marketing Platform. It enables advertisers to manage programmatic advertising campaigns using automated buying technology.

Depending on campaign configuration and available inventory, advertisers can use DV360 for display, video, audio, connected TV, and other supported advertising formats.

Key Capabilities

• Programmatic media buying.

• Campaign and budget management.

• Audience targeting.

• Inventory and deal management.

• Creative assignment and management.

• Automated and manual bidding options.

• Frequency management.

• Campaign reporting and optimization.

• Integration with other advertising and measurement technologies.

DV360 does not guarantee campaign performance. Results depend on the campaign strategy, inventory, targeting, creative quality, bidding, measurement, and execution.

2. Understanding DV360 Campaign Structure

A common DV360 hierarchy is:

Advertiser → Campaign → Insertion Order → Line Item → Creative

Understanding this hierarchy is essential for campaign setup and troubleshooting.

Advertiser

The advertiser is the top-level entity representing the business or client.

Advertiser-level settings and integrations may influence campaign management, measurement, and access to platform features.

Campaign

A campaign groups related advertising activity under a shared objective.

Campaigns may contain multiple insertion orders, depending on how the advertiser organizes budgets, objectives, audiences, or buying strategies.

Insertion Order (IO)

An insertion order groups line items and provides budget and flight-management controls.

Common settings include:

• Start and end dates.

• Budget.

• Pacing.

• Budget allocation across line items.

• Other available delivery settings.

The precise controls depend on the IO configuration and current DV360 capabilities.

Line Item

A line item defines a specific buying and delivery strategy.

It can contain settings such as:

• Inventory source.

• Targeting.

• Bidding strategy.

• Budget allocation.

• Flight dates.

• Frequency caps.

• Creative assignments.

• Optimization settings.

Creative

The creative is the advertisement delivered to users.

Examples include display banners, HTML5 ads, native creatives, and video assets, subject to the supported format and inventory.

Remember: When investigating a delivery problem, check the status and configuration at each relevant level instead of assuming the issue is always within the line item.

3. IO vs Line Item

A line item can be correctly configured but still fail to deliver because of an issue at the IO or campaign level.

4. Understanding Line Item Types

DV360 provides different line-item options for different buying approaches and inventory types. Availability and naming can change as Google updates the platform.

Depending on the setup, buying approaches may include:

• Open-auction buying.

• Private marketplace deals.

• Preferred deals.

• Programmatic guaranteed transactions.

• Other supported buying methods.

Line-item options can also vary according to the format, inventory, and campaign requirements.

Why Line Item Configuration Matters

The line item determines how the campaign evaluates and purchases eligible advertising opportunities.

An incorrect buying approach, unsuitable inventory configuration, restrictive targeting, or incompatible creative can affect delivery.

Before launch, verify that the line item matches the intended inventory, deal, creative format, and campaign objective.

5. DV360 Targeting Options

Targeting determines which advertising opportunities are eligible for a line item.

The options available depend on the campaign, inventory, market, and platform configuration.

Geographic Targeting

Targets eligible users or inventory associated with selected geographic locations.

Examples include countries, regions, and cities where supported.

Device Targeting

Allows campaigns to use available device-related controls, such as desktop, mobile, tablet, or connected TV environments where supported.

Audience Targeting

Uses eligible audience segments to help reach relevant users.

Possible audience sources include supported interest-based segments, custom segments, and first-party audience data.

Contextual Targeting

Targets advertising opportunities based on the content or context of the environment in which an ad may appear.

Inventory and Content Targeting

Campaigns may use available controls to select inventory sources, content categories, or other placement characteristics.

Retargeting

Retargeting aims to reach eligible users who previously interacted with a website, app, or other supported touchpoint.

It depends on valid audience collection, privacy requirements, consent, and platform eligibility.

Targeting Best Practices

• Align targeting with the campaign objective.

• Avoid unnecessary restrictions that limit delivery.

• Review audience availability and eligibility.

• Apply appropriate brand-safety and suitability controls.

• Verify geographic and device settings.

• Use first-party data only when its collection and use are permitted.

• Review targeting changes when performance shifts unexpectedly.

6. Understanding DV360 Bidding

Bidding determines how the advertiser competes for eligible impressions.

DV360 supports bidding approaches that can vary by line-item type and campaign objective.

CPM-Based Bidding

Cost per thousand impressions is a common programmatic buying metric.

A CPM bid expresses the cost associated with one thousand impressions, according to the applicable buying and reporting model.

Automated Bidding

Where available, automated bidding can adjust bids to support a defined objective using platform signals and campaign settings.

Performance-Oriented Bidding

Depending on the setup, bidding and optimization may focus on objectives such as conversions, conversion value, or other supported performance outcomes.

Bid Optimization Checklist

• Confirm that the bidding strategy matches the objective.

• Check bid settings and any applicable targets.

• Review campaign performance and conversion measurement.

• Assess whether targeting or inventory restrictions are limiting opportunities.

• Avoid making repeated bid changes without reviewing the effect.

• Check whether the campaign has sufficient time and relevant data for meaningful evaluation.

A bid that is too restrictive may reduce participation in eligible auctions. A higher bid does not automatically guarantee better business results.

7. Budget, Pacing, and Flight Dates

Budget and pacing settings influence how advertising spend is distributed over a campaign's duration.

Budget

The budget defines the amount allocated to campaign activity at the relevant level.

Confirm whether the intended budget is managed at the insertion-order level, line-item level, or through the applicable combination of controls.

Flight Dates

Flight dates define when the campaign or line item is scheduled to run.

Check start dates, end dates, and time-related settings when investigating delivery issues.

Pacing

Pacing controls how spending is distributed over time.

Depending on the available settings, campaigns may aim to spend evenly or deliver more aggressively within the scheduled period.

Common Pacing Problems

• Underspending: The campaign spends more slowly than expected.

• Overspending risk: Spend is progressing faster than planned.

• Uneven delivery: Spend varies substantially across days.

• Budget exhaustion: Available budget is depleted before the intended period ends.

Pacing Troubleshooting

1. Check campaign and IO status.

2. Verify the budget and remaining budget.

3. Confirm flight dates.

4. Review pacing configuration.

5. Check line-item budgets and allocations.

6. Examine bids and targeting restrictions.

7. Review inventory and deal availability.

8. Investigate creative eligibility.

9. Monitor delivery after making a change.

Do not immediately increase the budget when a campaign underspends. First identify whether the actual constraint is targeting, bidding, inventory, eligibility, or configuration.

8. Creative Management in DV360

Creatives must be suitable for the intended inventory and supported by the applicable line-item configuration.

Depending on the campaign, supported formats may include:

• Display banners.

• HTML5 creatives.

• Native ads.

• Video creatives.

• Other eligible advertising formats.

Creative Status and Approval

Creative availability and approval can influence whether an advertisement is eligible to serve.

When a creative is not delivering, check:

• Creative status.

• Approval or policy status.

• Format compatibility.

• Dimensions and technical requirements.

• Assignment to the correct line item.

• Landing-page accessibility.

• Other inventory-specific restrictions.

Important: A creative that has been uploaded or assigned is not necessarily eligible to serve in every intended environment.

Creative QA Checklist

• Confirm the correct creative is assigned.

• Verify supported format and dimensions.

• Check approval and policy status.

• Test the destination URL.

• Confirm that the offer and landing page match.

• Review tracking requirements.

• Validate rendering where appropriate.

9. Deals and Inventory Management

Programmatic buying can involve open-auction inventory and negotiated deals.

Open Auction

Eligible buyers compete for available impressions through the applicable auction environment.

Private Marketplace

A private marketplace provides selected buyers with access to specified inventory under agreed conditions.

Preferred Deal

A preferred deal generally provides a buyer access to negotiated inventory under specified pricing or buying conditions without necessarily creating a commitment to purchase all available impressions.

Programmatic Guaranteed

Programmatic guaranteed buying typically involves an agreed inventory commitment and pricing arrangement executed through programmatic technology.

Deal Troubleshooting

If a deal line item is not delivering, check:

• Deal status and dates.

• Buyer and seller configuration.

• Inventory availability.

• Line-item targeting.

• Bid settings and applicable deal terms.

• Creative compatibility and approval.

• Budget and pacing.

• Any platform-specific eligibility restrictions.

Deal availability, terminology, and transaction mechanics vary. Confirm the actual deal configuration before making changes.

10. Essential DV360 Metrics and Formulas

Impressions

The number of impressions recorded by the applicable reporting system.

Clicks

The number of recorded ad clicks.

CTR — Click-Through Rate

Measures clicks relative to impressions.

Formula:

CTR = (Clicks ÷ Impressions) × 100

CPM — Cost per Thousand Impressions

Formula:

CPM = (Cost ÷ Impressions) × 1,000

CPC — Cost per Click

Formula:

CPC = Cost ÷ Clicks

Conversions

The number of conversion actions recorded under the selected measurement configuration.

CPA — Cost per Acquisition

Formula:

CPA = Cost ÷ Conversions

Conversion Rate

Formula:

Conversion Rate = (Conversions ÷ Eligible Interactions) × 100

Specify whether the denominator is clicks, sessions, or another defined interaction.

Viewability Rate

Formula:

Viewability Rate = (Viewable Impressions ÷ Measured Impressions) × 100

Use the applicable measurement provider's definition.

ROAS — Return on Ad Spend

Formula:

ROAS = Attributed Conversion Value ÷ Advertising Cost

A ROAS of 3.0 represents ₹3 of attributed conversion value for every ₹1 of advertising cost. It does not represent net profit.

11. Reporting and Performance Analysis

Use reporting to identify what is working, where delivery is constrained, and whether the campaign is meeting its business objective.

Useful reporting dimensions and metrics may include:

• Campaign and line item.

• Date.

• Creative.

• Device.

• Geographic location.

• Inventory or deal information.

• Impressions and clicks.

• Cost and CPM.

• Conversions and CPA.

• Viewability information.

• Conversion value and ROAS, where measurement supports them.

The exact dimensions available depend on the report, data source, campaign setup, and platform capabilities.

How to Analyze a Campaign

Step 1: Check delivery. Confirm that impressions and spend are progressing as expected.

Step 2: Review costs. Compare CPM, CPC, and total spend with the campaign's objective and expectations.

Step 3: Evaluate engagement. Examine CTR and relevant post-click behavior.

Step 4: Evaluate conversions. Review conversion volume, CPA, conversion value, and downstream business outcomes.

Step 5: Segment the data. Use available dimensions to investigate differences across creatives, devices, geographies, or inventory.

Step 6: Validate measurement. Check whether tracking issues or reporting differences could explain unexpected results.

Do not rely on one metric in isolation. For example, a high CTR does not necessarily indicate strong conversion performance.

12. DV360 Troubleshooting Framework

Use this structured process when a campaign suddenly stops delivering or underperforms.

Step 1: Reproduce the Issue

Confirm the issue in platform reporting. Identify whether it affects the entire campaign, a specific IO, one line item, or particular creatives.

Step 2: Check Status

Review the status of the campaign, insertion order, line item, and creative.

Look for paused items, completed flights, budget limitations, approval issues, or other delivery restrictions.

Step 3: Identify When the Problem Started

Compare performance before and after the change.

Determine whether the issue began after a configuration update, budget adjustment, creative replacement, or other event.

Step 4: Review Change History

Inspect recent changes to targeting, bidding, budgets, dates, pacing, and creatives.

Step 5: Check Targeting

Look for restrictive audience settings, geographic limitations, device filters, inventory exclusions, or incompatible targeting combinations.

Step 6: Check Creative Eligibility

Confirm that the correct creative is assigned, approved, compatible, and accessible.

Step 7: Review Bidding

Check whether bids or automated bidding targets are limiting participation in eligible auctions.

Step 8: Review Budget and Pacing

Verify IO and line-item budgets, remaining budget, pacing, and flight dates.

Step 9: Inspect Inventory and Deals

Check inventory availability, deal configuration, and buying-method restrictions.

Step 10: Validate Tracking

If delivery is normal but conversions have declined, verify the measurement setup before changing campaign settings.

Step 11: Fix, QA, and Monitor

Make the appropriate correction, verify the configuration, and monitor delivery and performance to confirm the outcome.

Quick troubleshooting sequence:

Reproduce → Status → Drop Time → Change History → Targeting → Creative → Bid → Budget & Pacing → Inventory & Deals → Tracking → Fix → QA → Monitor
