Google Display & Video 360 (DV360): The Complete Beginner's Guide to Programmatic Advertising

If you've run campaigns on Google Ads or Meta Ads and are now being asked to "just set this up in DV360," the jump can feel steep. The interface is deeper, the vocabulary is different, and the number of options can be overwhelming.

At Optimum360 Agency, we work with enterprise-level media buying every day. This guide walks through what DV360 is, how it fits into programmatic advertising, how its structure differs from other platforms, and how a campaign is built from scratch.

What Is DV360?

Display & Video 360 (DV360) is Google's demand-side platform (DSP), a tool advertisers and agencies use to buy digital ad inventory across a huge range of publishers, formats, and devices from one dashboard.

Google didn't build DV360 from scratch. Like YouTube, it came through acquisition, starting with DoubleClick, which Google bought in 2008. Today it sits at the heart of Google's Marketing Platform.

How Programmatic Advertising Works

To understand DV360, you need to understand the ecosystem around it.

The whole process is automated, and that's why it's called programmatic advertising. When you buy an ad slot on a publisher's homepage through DV360, no phone calls or manual negotiations are needed.

Who Uses DV360, and Why?

DV360 is typically used by advertisers and agencies who have outgrown Google Ads. Picture a global brand launching a new phone across many countries at once. Each market has its own key publishers, budgets, audiences, and objectives. Managing that through standard self-serve tools quickly becomes messy. DV360 gives you one place to plan, buy, control, and report on all of it.

Here is what DV360 offers that Google Ads and Meta Ads generally don't:

• Broader inventory access: Connected TV (CTV), audio and podcast platforms, mobile apps, and digital out-of-home (DOOH) screens such as billboards and mall displays, all bookable from one desk in any city.
• More sophisticated audience options: Third-party data providers are integrated directly, so you can reach niche segments (for example, users showing intent to travel to a specific destination), alongside Google's own affinity and in-market audiences.
• Brand safety controls: You choose exactly where your ads run, and where they don't, and you can integrate third-party verification partners.
• Detailed frequency management: Caps can be set at the campaign, insertion order, and line item level.
• Transparent media buying: You can see how much went to the publisher, how much to platform fees, and how much to data costs.
• Multiple buying methods, covered below.

Multiple Ways to Buy Media

On Google Ads and Meta, you're essentially working with open auctions. DV360 supports several buying modes:

You can combine all of these, plus CTV, YouTube, and DOOH, in a single campaign. That flexibility is a major reason large brands rely on DV360.

DV360 Hierarchy: Two Extra Layers

The structure of DV360 is one of the biggest adjustments for people coming from other platforms.

The two additions are:

• Partner: The top-level layer, mainly used by agencies to manage many clients. Each client usually gets its own advertiser account.
• Insertion order (IO): A layer between campaign and line item that lets you split a campaign into budget-controlled segments, such as by country, flight, or objective.

For example, a launch campaign for a phone might have one campaign, then a separate insertion order for each country (each with its own budget), and inside each insertion order several line items: open auction, programmatic guaranteed deals, YouTube, and so on.

Step-by-Step: Setting Up a DV360 Campaign

1Create the Campaign

Inside your advertiser account, click New → Campaign and add a name, a goal (such as raising awareness), a KPI, planned spend, and dates.

2Create an Insertion Order

The IO is where budget and pacing controls start to take effect. Key settings include:

• Type and objective: Choose standard (display and video), CTV, or DOOH. Selecting an objective such as brand awareness narrows down the available KPIs, bid strategies, and line item types. If you want maximum flexibility at line item level, create the IO without an objective.
• Budget: Set in currency or impressions, with the option to add multiple budget segments across different date ranges. This is useful for seasonal pushes, like spending a small share of budget before a holiday and most of it in the peak days.
• Pacing: Choose even pacing to spread spend across the flight or day, or ASAP to spend faster. Big brands often struggle with underpacing, so front-loading can be useful. Pacing can be set per flight or per day.
• KPI: For awareness campaigns, options include cost per thousand viewable impressions (vCPM) and viewability percentage.
• Optimization level: Optimize at the IO level (similar to campaign budget optimization in Meta), or manage bids and budgets at the line item level.
• Frequency cap: More on this below.
• Partner costs: Agencies can add their own fees (fixed CPM or percentage markup) so they flow through to client invoices.

3Create Line Items

Line items are where the media plan gets executed. Options depend on your IO objective and can include display, video, CTV, audio, mobile app install, and YouTube.

Key settings:

Understanding Viewability

Viewability is central to DV360 planning. An ad counts as viewable when it actually appears on screen for people to see, under the industry standard (MRC) of at least 50% of its pixels in view for one continuous second for display ads. An ad placed far down a page that nobody scrolls to still counts as an impression, but it isn't viewable, so you may be paying for nothing. Optimizing to viewable impressions or targeting a high viewability percentage helps your budget go toward ads that had a real chance of being seen.

Third-Party Audiences and Costs

DV360's integrations with third-party data providers give you very granular audiences (for example, users showing recent intent to travel to a certain destination). Keep in mind that these carry an additional CPM cost paid to the data provider on top of your media cost, so factor it into your bid strategy and budget.

Planning and the Marketplace

Two features worth exploring beyond basic setup:

• Inventory planning: You can build a campaign structure (campaigns, insertion orders, line items) in advance, get client approval, and then generate it in one click.
• Marketplace: This is where you discover publishers and negotiate deals. You can browse by format, audience, or category, or search directly for a publisher, review its traffic and audience information, and send a proposal request with your budget, dates, and targeting. The publisher responds with pricing. If you accept, the deal appears in the Deals and packages section of your line item, and you have a programmatic guaranteed campaign.

How to Get Access to DV360

Direct sign-up isn't available the way it is for Google Ads or Meta. Historically, Google worked directly with large advertisers, but today access typically goes through authorized Google partners and resellers. You can find them in Google's DV360 partner directory, filtered by country. Requirements and commercial terms vary by partner and region.

DV360 vs Google Ads: Which Do You Need?

DV360 isn't automatically "better," and it's more complex to run and manage. It's the right choice when you need premium inventory access, guaranteed placements, granular controls, and enterprise-level structure.
