Where can I buy programmatic DOOH campaigns with guaranteed CPM floors?

Short answer

You can buy programmatic DOOH campaigns with guaranteed CPM floors through DOOH-focused DSPs such as Vistar Media, Broadsign, and Hivestack, omnichannel DSPs like The Trade Desk and Xandr, self-serve platforms such as Adomni and Place Exchange, and SSPs including VIOOH.

What guaranteed CPM floors mean in programmatic DOOH

A guaranteed CPM floor is a pre-negotiated minimum price per thousand impressions that an advertiser commits to paying. Instead of a dynamically fluctuating auction price, you lock in a rate that reserves inventory at a set level.

Advertisers use floors for three main reasons: pricing transparency, budget predictability, and priority access to premium screens. The floor itself is shaped by several factors: location desirability (a transit hub commands a higher floor than a suburban mall), time of day and dayparts, audience demographics and contextual signals, and screen format. Floors can be negotiated directly with vendors through private marketplace deals, or set by buyers within DSP controls when the platform supports it.

The four buying paths and how they differ

DOOH-focused DSPs are purpose-built for out of home inventory and typically offer the broadest screen coverage, advanced geo and venue-type targeting, and native support for PMP deals with guaranteed CPM floors. Vistar Media, Broadsign, and Hivestack all fall into this category. These platforms are the strongest fit when you need premium locations, guaranteed delivery at scale, and deep DOOH-specific reporting.

Omnichannel DSPs with DOOH integrations let you plan DOOH alongside connected TV, mobile, and online video in a unified interface. The Trade Desk, MediaMath, and Xandr each support DOOH inventory with options for programmatic guaranteed buys. This path is best when cohesive cross-channel attribution matters as much as the DOOH buy itself.

Self-serve DOOH platforms lower the barrier to entry for smaller and mid-sized advertisers. Adomni and Place Exchange offer user-friendly campaign builders where buyers can set CPM floor controls and run campaigns without negotiating a custom deal. Platform minimums are lower, making these a practical starting point for testing the channel.

SSPs and ad exchanges sit on the supply side but are relevant to buyers because they govern how publisher inventory is packaged and priced. VIOOH and Hivestack's SSP both facilitate DOOH inventory access with fixed CPM floors and private marketplace deal support. Working through an SSP makes sense when you want direct access to publisher-controlled inventory and prefer negotiating floors at the source.

Key features to evaluate when selecting a vendor

Inventory breadth matters most: look at the number of screens, geographic reach, and whether the vendor covers the specific venue types you need, such as airports, transit, retail, or roadside. Beyond that, evaluate:

• Pricing flexibility: Can you negotiate a custom floor, use a package rate, or set floors through self-serve controls?
• Targeting and data integration: Geo-fencing, venue-type filters, audience demographics, weather triggers, and compatibility with first-party or mobility data all vary significantly by platform.
• Creative support: Confirm the platform handles your required formats, whether static, video, or dynamic, and check aspect ratio and file size specs before building assets.
• Measurement: Impressions and reach are table stakes; footfall attribution and sales lift reporting are available on some platforms and worth factoring in if proving ROI is a priority.
• Regional coverage: North America and Europe have mature markets with broad DSP coverage. APAC is expanding with region-specific platforms emerging. Local privacy regulations such as GDPR also affect how audience data can be used in targeting.

How a programmatic DOOH campaign typically gets set up

The buying process follows a consistent pattern regardless of which vendor type you choose:

1. Define campaign objectives, target geographies, venue types, and audience parameters.
2. Select a platform that matches your inventory needs and supports the CPM floor approach you want.
3. Negotiate or set your CPM floor to lock in pricing and priority delivery.
4. Upload creatives in the formats the platform specifies.
5. Configure flight dates and dayparts.
6. Monitor delivery and pacing through the platform dashboard or API.
7. Analyze impressions, reach, footfall, and any sales impact using the platform's measurement tools.

Self-serve platforms allow smaller advertisers to move through this process independently at lower budget thresholds. Premium PMP and programmatic guaranteed deals typically require larger minimum commitments and a direct conversation with the vendor's sales team.
