How DOOH Advertising Works: A Complete Guide for Venues and Advertisers

What Is DOOH Advertising?

Digital out-of-home (DOOH) advertising refers to any paid advertising displayed on digital screens in publicly accessible or semi-public commercial locations — outside of the home environment. This includes:

• Indoor venue screens in bars, restaurants, gyms, waiting rooms, and retail stores
• Large-format outdoor digital billboards and transit displays
• ATM and kiosk screens in high-traffic locations
• Gas station pump screens, elevator displays, and airport media

YAXI TV operates in the indoor venue segment — bars, restaurants, gyms, auto service centers, retail, and waiting rooms — which differs from outdoor billboards in several important ways: shorter viewing distances, more controlled environments, longer dwell times, and more predictable audience contexts.

Unlike traditional out-of-home advertising (static billboards and posters), DOOH screens can be updated remotely and instantly, scheduled by time of day and day of week, targeted to specific venue types, and verified with machine-generated proof-of-play logs that traditional OOH cannot produce.

The Three Actors in Every DOOH Transaction

Every DOOH ad impression involves three distinct parties, each with a different role and incentive:

1. The Venue (Publisher)

The business that owns or controls the physical screen location. The venue provides two things: the audience (their customers) and the physical space where the screen lives. In exchange, they receive a share of advertising revenue based on the verified impressions their screens deliver.

A venue's value to advertisers is determined primarily by: venue category (what kind of place it is), foot traffic volume, dwell time (how long customers spend in the space), and geographic location. A busy gym in Los Angeles with 400 members per day has more advertising value than a small convenience store with 50 daily visitors.

2. The Advertiser (Buyer)

The brand or business paying to reach the venue's audience. Advertisers may be local businesses running neighborhood campaigns, regional brands targeting specific cities, or national brands running geo-targeted campaigns as part of a larger media mix.

Advertisers care about: reaching the right audience in the right context (a gym screen reaches health-conscious adults; a bar screen reaches social evening audiences), verifiable delivery (did the ad actually play?), and cost efficiency (CPM rates relative to other channels).

3. The Platform (Ad Network / SSP)

The technology layer connecting venues to advertisers. The platform manages the technical delivery of ads (connecting to demand sources, routing creatives, managing playlists), handles billing and revenue calculation, generates proof-of-play records, and provides reporting to both venues and advertisers.

YAXI TV operates in this role — connecting venue screens to programmatic demand from DSPs through Vistar Media and Google Ad Manager, while also providing the CMS, player software, and analytics infrastructure. This is what makes YAXI TV a supply-side platform (SSP) in industry terminology, though the platform also provides services beyond pure inventory management.

How Programmatic DOOH Works

Programmatic DOOH automates the buying and selling of ad impressions using real-time bidding technology — the same fundamental infrastructure used in digital display advertising, adapted for the physical screen environment.

The Participants in Programmatic DOOH

• DSP (Demand-Side Platform): The tool advertisers or agencies use to buy programmatic inventory. DSPs like The Trade Desk, DV360, or specialized DOOH platforms let buyers set targeting parameters, bid strategies, creative assignments, and campaign budgets. When screen inventory is available, DSPs bid on it automatically.
• SSP (Supply-Side Platform): The technology that represents the venue's inventory to DSPs. The SSP aggregates available ad slots across its screen network, creates bid request packages with venue metadata, and runs the auction that selects the winning advertiser. YAXI TV's ad server functions as an SSP for the screens in its network.
• Demand Partners / Exchanges: Platforms like Vistar Media and Google Ad Manager that operate in the middle layer — they aggregate demand from multiple DSPs and connect it to SSPs. YAXI TV connects to Vistar Media and Google Ad Manager as demand aggregators, which means DOOH buyers using those platforms can access YAXI TV inventory.

The Real-Time Bidding Sequence

When a YAXI TV screen reaches an ad break slot in its playlist, the following sequence occurs in milliseconds:

1. The YAXI TV ad server generates a bid request containing: the screen's venue type, geographic location, daypart, creative requirements (resolution, duration), and floor price.
2. This bid request is sent to connected demand partners (Vistar Media, Google Ad Manager), who distribute it to eligible DSPs.
3. DSPs with campaigns targeting the venue's profile submit bid responses with a CPM price and creative identifier.
4. The ad server evaluates all bid responses and selects the winning bid (highest valid CPM above the floor price).
5. The winning creative is returned to the player device and displayed on the screen.
6. A proof-of-play record is generated upon display completion.

This entire sequence — from bid request generation to creative delivery — typically takes 500ms to 2 seconds, which is why ad breaks in digital signage appear brief before the content begins. The latency is deliberate: if no bid is received within the timeout window, the slot falls back to house content or the next playlist item.

Direct-Sold DOOH

Not all DOOH inventory sells programmatically. Direct-sold campaigns are negotiated and booked directly between an advertiser (or their agency) and the platform or network owner, bypassing the real-time auction.

When direct selling makes sense:

• When the advertiser wants guaranteed placement in specific venues or at specific times (not available in programmatic buying, which is opportunistic)
• When the campaign requires custom creative formats or non-standard durations
• When the advertiser wants a single point of contact and managed campaign service
• When the advertiser is new to DOOH and wants guidance rather than self-serve buying

For YAXI TV venues, direct-sold inventory is managed by the YAXI TV sales team and typically commands higher CPMs than programmatic fill. However, programmatic fill provides inventory that runs without requiring a sales effort — making it the foundation for most venues' revenue model.

Ad Delivery: From Bid to Screen

Once a bid is won, the creative must reach the screen. Unlike web advertising (where creative is rendered in a browser at the moment of display), DOOH has different delivery mechanics depending on the creative format:

• Pre-cached creatives: For campaigns booked in advance, creative files (images and videos) are downloaded to the player device and cached locally. When the ad break arrives, the cached file plays immediately without requiring a download. This is how most planned campaigns work and why ad playback is smooth even on modest internet connections.
• Real-time streaming creatives: Some programmatic campaigns deliver creative at the moment of ad break — the player fetches the creative URL in real time. This requires a reliable network connection at the moment of the ad break and is more sensitive to connectivity issues.

For creative formats and technical requirements specific to the YAXI TV network, see the creative specifications page.

Proof-of-Play and Impression Verification

Proof-of-play (POP) is the mechanism that makes DOOH verifiable — and it is what distinguishes digital out-of-home from traditional OOH media like printed posters and static billboards.

When an ad plays on a YAXI TV screen, the player device generates a POP record immediately upon completion of the display. This record is transmitted to the cloud in near real time and contains:

• Screen ID: The unique identifier of the specific physical device
• Creative ID: The specific ad creative that played
• Campaign/line item ID: Which campaign and flight the ad belongs to
• Timestamp: Exact date, time, and time zone of playback — accurate to the second
• Duration: How long the ad displayed, in seconds
• Venue metadata: Venue type, geographic region, screen position

POP records are the authoritative source of truth for both venue revenue payouts and advertiser billing. They are not estimated, sampled, or modeled — they are event-driven logs generated at the moment of actual display.

This creates a closed-loop accountability system: advertisers pay for what was actually delivered (as logged by POP), venues are paid for what was actually delivered (as verified by the same POP records), and discrepancies between ad decision records and POP logs surface any delivery anomalies.

How Venue Revenue Is Calculated

Venue revenue in DOOH flows from the advertiser's CPM payment through the technology stack to the venue partner. The waterfall looks roughly like this:

1. Advertiser pays CPM: The advertiser pays a CPM rate for the impressions delivered by their campaign. This rate varies based on targeting, market, venue category, and how competitive the auction was.
2. Demand partner fee: Platforms like Vistar Media and Google Ad Manager take a percentage for operating the exchange and demand aggregation layer.
3. Platform fee: YAXI TV retains a percentage for operating the ad server, player infrastructure, CMS, reporting, and network management.
4. Venue revenue share: The remaining revenue is distributed to the venue partner based on verified POP impressions from that venue's screens during the billing period.

The exact revenue share percentage for YAXI TV venue partners is set during the onboarding process and governed by the partner agreement. We do not publish standard rates here because they vary by venue type, market, and arrangement.

What drives venue earnings:

• Total verified impressions: Screens with more hours of operation and higher foot traffic deliver more impressions.
• Market advertiser demand: Markets with more active DOOH advertisers have higher fill rates and CPMs.
• Venue category: Certain venue types (fitness, medical) may attract higher-CPM demand from relevant advertisers.
• Ad fill rate: Screens that are consistently online and have minimal category blocks fill more inventory.

We do not publish guaranteed earnings estimates because actual results depend on all of these variables, which we cannot control on behalf of any specific venue.

Targeting in DOOH: What's Real and What Isn't

DOOH targeting differs fundamentally from digital display advertising, and understanding the difference helps both venues and advertisers set accurate expectations.

What DOOH targeting is based on:

• Venue type: The category of business (gym, bar, restaurant, auto shop, etc.) predicts the demographic and behavioral profile of its customers.
• Geographic location: City, metro area, or neighborhood targeting based on where the screen is physically located.
• Daypart: Time of day (morning commute, lunch, evening, late night) predicts audience context and mindset.
• Day of week: Weekday vs weekend audience compositions differ significantly for many venue types.

What DOOH targeting is NOT:

• DOOH does not use cookies or device IDs to track individual viewers
• DOOH targeting is probabilistic (reaching the audience type the venue attracts) rather than deterministic (reaching a specific known individual)
• You cannot retarget a specific person who saw a DOOH ad

This makes DOOH a reach medium rather than a precision targeting medium — excellent for brand awareness, local market coverage, and contextually relevant messaging, but not a substitute for direct-response digital channels where individual user targeting matters.

Common Pitfalls and Misconceptions

For venues

• "My screens will be full of ads immediately" — Fill rates depend on market demand and monotization approval. In new markets or lower-demand time windows, a meaningful percentage of ad break slots may go unfilled and display entertainment or house content instead.
• "I'll earn a predictable amount per month" — Revenue varies with fill rate, market conditions, and seasonal advertiser demand. It is not a fixed amount.
• "More screens always means more revenue" — More screens means more potential impressions, but revenue per screen depends on the audience reaching each screen. An additional screen in a low-traffic corner generates less than a well-placed screen in a high-dwell zone.

For advertisers

• "Reach works the same as online advertising" — DOOH reach is estimated based on venue traffic data, not tracked to individual devices. The same person may see your ad multiple times if they frequent a venue. Frequency and reach calculations use different methodology than digital advertising.
• "DOOH works for direct response" — DOOH is most effective for awareness, brand building, and contextual messaging. It is generally not the right channel for driving immediate clicks or form fills. Attribution requires secondary measurement (promo codes, URL tracking) rather than pixel-based conversion tracking.
• "Proof-of-play guarantees viewership" — POP confirms that the creative displayed on the screen for the logged duration. It does not verify that anyone was looking at the screen at that moment. Viewership is estimated based on venue traffic data.
