Programmatic DOOH vs Direct Buying in Europe: Which Approach Fits Your Campaign?

If you have already decided that Digital Out-of-Home can add value to your wider media mix, the next question is practical:

How should you buy it?

Should you secure inventory directly with media owners? Activate programmatically? Or use a combination of both?

For advertisers and agencies running campaigns across Europe, there is no single correct answer.

The right buying route depends on what you are trying to achieve, the locations and formats you need, how much flexibility the campaign requires, and which inventory is available through each buying method.

The important shift is to stop thinking of direct and programmatic DOOH as competing choices.

They are different ways of accessing the same medium — and each can play a useful role within the right campaign.

What Is Direct DOOH Buying?

Direct buying generally involves agreeing inventory, campaign dates, formats and commercial terms directly with a media owner or through an OOH buying partner.

It can be particularly useful when your campaign is built around specific placements that you already know you want.

Imagine a brand launching a new product in London.

The campaign brief identifies a particular group of high-profile digital screens around key retail and commuter locations. Those placements are central to the media plan and need to run during a defined launch period.

In that situation, securing the inventory directly may make sense.

Direct buying can be well suited to campaigns involving:

• specific or premium locations
• fixed campaign periods
• predetermined screen packages
• negotiated media-owner agreements
• campaigns where placement certainty is especially important

Direct should not be viewed as the “old” way of buying DOOH.

For many campaign requirements, it remains a practical and effective route to market.

What Is Programmatic DOOH?

Programmatic DOOH uses advertising technology to support the buying and activation of eligible digital OOH inventory.

For marketers already familiar with digital media buying, parts of the process will feel familiar: campaign parameters can be set around factors such as location, timing, audience or context, depending on the inventory and data available.

This can make pDOOH useful when a campaign requires greater flexibility.

For example, a campaign could be designed to activate during selected dayparts, focus on particular environments or adjust activity around contextual conditions where those capabilities are supported.

Programmatic can also make it easier to manage some DOOH activity alongside other digitally activated media.

But there is an important distinction.

Programmatic does not simply mean open-auction buying.

The World Out of Home Organization's 2026 pDOOH study found that 75.7% of global programmatic DOOH spend in 2025 was transacted through Private Marketplace deals, showing that much of the market still uses structured agreements between selected buyers and sellers. worldooh.org

That is useful context for digital marketers entering DOOH: automation can change how inventory is accessed and activated without removing the importance of inventory relationships, availability or commercial agreements.

Direct vs Programmatic DOOH: How Should You Decide?

The question is not “Which buying method is better?” It is: “Which buying route best supports this campaign?”

Budget alone should not determine the choice.

Start with the campaign objective, audience, environment and inventory requirements, then decide how that media should be accessed.

Why the Answer Can Change Across Europe

European DOOH is already highly digital, but the maturity of programmatic buying is not identical from one market to another.

WOO's latest pDOOH research illustrates that difference. Its September 2026 study, based on full-year 2025 supply-side revenue, estimates programmatic DOOH penetration at 21.3% across Western Europe. Germany reached 31.8%, the highest penetration among major markets globally, while France reached 16.7%.

These figures measure programmatic DOOH spend as a share of DOOH spend, not the overall digitisation of OOH.

That distinction matters.

A market can have substantial digital OOH infrastructure without every screen, format or media owner being accessible through the same programmatic buying route.

So a campaign spanning London, Berlin, Paris and Milan might have one audience strategy but use different activation methods in each market.

The buying route should follow the opportunity available locally rather than forcing every campaign into the same model.

Sometimes the Better Answer Is Both

For many European campaigns, direct and programmatic buying do not need to be mutually exclusive.

Consider a campaign built around a major product launch.

You might secure high-impact hero placements directly in central London because those specific screens are essential to the campaign.

At the same time, programmatic DOOH could support additional activity across relevant commuter, retail or business environments where suitable inventory is available.

The strategy stays consistent.

The buying method changes according to what each part of the campaign needs to do.

This hybrid approach can be particularly useful when you want the certainty of predetermined placements alongside the flexibility of programmatic activation.

It also reinforces an important point:

One DOOH strategy does not necessarily require one buying method.

Buying Should Start With Planning, Not the Platform

It is easy to start with the technology question:

“Can we buy this programmatically?”

But the better starting point is the campaign itself.

Who are you trying to reach? Where are the most relevant environments? Are there specific screens you need, or do you need more flexibility around timing and location?

Once those decisions are clear, the buying route becomes easier to define.

A campaign built around fixed premium placements may lean towards direct buying. A campaign that needs greater flexibility around timing, audience or context may benefit from programmatic activation. In some cases, a combination of both will make more sense.

The important point is that buying should follow the media strategy, not lead it.

From there, the workflow becomes more straightforward:

Plan → Activate → Verify → Measure

Planning helps identify the right audience and environments. Activation determines how the inventory is accessed. Delivery data confirms what ran, and measurement helps assess what the campaign contributed.

The buying method is one decision within the wider campaign — not the strategy itself.

Connecting Direct and Programmatic DOOH Across Europe

This is where a more connected approach becomes valuable.

Moving Walls helps advertisers and agencies use audience and location intelligence to plan DOOH campaigns, identify relevant media opportunities and activate through direct or programmatic buying routes depending on campaign requirements and available inventory.

Campaign delivery and measurement can then be brought back into the same wider workflow.

Moving Walls' European campaign offering follows this approach across planning, activation and measurement rather than treating programmatic buying as a standalone activity.

The objective is not to make every campaign programmatic.

It is to help teams choose the activation approach that fits the media strategy.

So, Direct or Programmatic?

If your campaign depends on fixed premium placements, negotiated packages or specific inventory, direct buying may be the logical choice.

If you need greater flexibility around timing, location, contextual activation or available audiences, programmatic DOOH can create additional options.

And if the campaign requires both certainty and flexibility, the answer may be a combination.

For European marketers, the more useful question is therefore not:

“Should we buy DOOH directly or programmatically?”

It is:

“What are we trying to achieve - and which buying route gives this campaign the right combination of inventory, control and flexibility?”

That is the decision that should guide activation.
