How to Choose a DV360 Agency That Actually Moves the Needle

Why the Right DV360 Agency Matters

Display & Video 360 is one of the most capable demand-side platforms available, but capability and outcomes are not the same thing. The platform rewards teams who understand its bidding logic, inventory sources, audience architecture and measurement stack — and it quietly punishes those who don't. That's why so many marketing leaders start their DV360 journey by looking for a partner rather than building an in-house desk from scratch.

A good DV360 agency does more than "run campaigns." It brings platform access, negotiated inventory relationships, trafficking discipline, and a measurement framework that ties spend back to business results. The wrong one simply relabels your budget and adds a margin. This guide will help you tell the difference.

What a DV360 Agency Actually Does

Before you evaluate vendors, it helps to be clear about the work. A capable DV360 partner typically owns or supports:

• Account and seat provisioning — giving you access to DV360 under a partner or reseller structure, or helping you stand up your own.
• Campaign architecture — insertion orders, line items, audience lists and creative rotation built to a logical, testable structure.
• Inventory strategy — combining open exchange, private marketplaces (PMPs), programmatic guaranteed deals and Google-owned inventory like YouTube.
• Audience and first-party data activation — connecting your CRM segments, building lookalikes, and layering contextual and third-party signals responsibly.
• Optimisation — bid strategy tuning, frequency management, brand safety controls and creative testing.
• Measurement — attribution, incrementality thinking, and reporting that a CFO can actually read.

If a prospective agency can't speak fluently to each of these, treat that as a signal.

The Main Engagement Models

There is no single "right" way to work with a DV360 agency. The best structure depends on your team's maturity, your spend level, and how much control you want to retain.

Model	Who owns the platform	Best for	Trade-off
Self-serve (supported)	You	Teams with in-house traders wanting their own seat	You carry execution risk
Managed service	The agency	Lean teams wanting outcomes, not operations	Less day-to-day visibility
Co-managed	Shared	Teams building capability while running live campaigns	Requires clear role definition
Partner account	The agency (you get access)	Advertisers below direct-seat thresholds	Dependent on partner terms

Each of these maps to a distinct way of working. If you want to own the seat and simply need enablement, a self-serve DV360 account is often the cleanest path. If you'd rather hand execution to specialists, DV360 managed services remove the operational burden entirely. And if you're building an internal desk but need cover today, co-managed services let you learn while you scale.

When a partner account makes sense

Many advertisers don't meet the minimum spend commitments required for a direct DV360 seat, or simply don't want the overhead of a direct contract. A DV360 partner account gives you access to the full platform through an established partner, usually with faster onboarding and shared billing. It's a pragmatic route into the ecosystem without a long procurement cycle.

Questions to Ask Before You Sign

The sales conversation is where good agencies separate themselves. Come prepared with pointed questions and listen for specific, unhedged answers.

On transparency

• How is your fee structured — flat management fee, percentage of media, or a hybrid?
• Do we get log-level or platform-level access to see actual spend and placements?
• Who owns the data, audiences and campaign structures if we leave?

On capability

• Which inventory relationships and PMP deals can we access through you?
• How do you approach brand safety, viewability and ad fraud controls?
• Walk me through how you'd structure a first-party audience strategy for our business.

On measurement

• How do you attribute conversions, and how do you think about incrementality versus last-click?
• What does a typical reporting cadence and dashboard look like?

On the team

• Who actually manages the account day to day, and what's their DV360 experience?
• How do you handle escalations and platform issues?

Answers that are vague, defensive about data access, or evasive on fees are the most common early warning signs.

Red Flags to Watch For

Not every problem shows up in a pitch deck. Watch for these patterns during evaluation and the first 90 days:

• Opaque media costs. If you can't reconcile what you paid against what reached inventory, you don't have a partner — you have a reseller.
• One-size-fits-all campaign templates. Reused structures with no thought given to your funnel or audiences rarely perform.
• Vanity metrics. Impressions and clicks without a line to pipeline, revenue or incremental reach signal a measurement gap.
• No exit plan. If leaving means losing your audiences and historical data, you're locked in by design.
• Overpromising. Anyone guaranteeing specific results before understanding your data and margins is selling, not advising.

Managed, Self-Serve or Co-Managed: Making the Call

The decision usually comes down to three variables: internal expertise, available time, and desire for control.

• If you have experienced traders and want to keep everything in-house, choose supported self-serve and use the agency for enablement and troubleshooting.
• If your team is stretched and you care about outcomes more than operating the console, managed services free you to focus on strategy.
• If you're actively building capability, co-managed engagements let your team shadow experts on live budgets — the fastest way to learn without the risk of learning alone.

Many organisations move along this spectrum over time, starting managed and gradually taking the wheel. A good partner supports that transition rather than resisting it. You can compare the full range on our services page.

What Good Looks Like After Onboarding

A healthy DV360 engagement shows measurable signs within the first few months:

• Campaign structures are documented and logical, not a tangle of duplicated line items.
• Reporting connects media activity to business outcomes, with clear commentary on what changed and why.
• Optimisation decisions are explained, not hidden behind a black box.
• First-party data is being activated and refreshed, not sitting idle.
• You feel more informed about programmatic each quarter, not less.

If you're getting slick dashboards but can't explain to your leadership why performance moved, something is missing.

Bringing It Together

Choosing a DV360 agency is really a decision about where your team wants to invest its attention. The platform's power is real, but so is its complexity — and the gap between a mediocre setup and a well-run programme is enormous. Prioritise transparency, insist on data ownership, match the engagement model to your team's reality, and hold your partner to measurement that a business leader would recognise.

Done well, a DV360 partnership becomes a genuine performance advantage rather than another line on the invoice.
