About this format
Highways, arterials and city approaches, using LED displays that rotate multiple advertisers. Unlike online media, the physical context is part of the product: approach angle, viewing distance, speed, dwell time, surrounding light and audience purpose all affect performance.
The label is not always standardized internationally. Suppliers may use a brand name, sheet size, panel nickname or local term for a similar canvas. Treat “digital bulletin” as a starting description, then verify the individual unit and its current specification sheet.
How to buy
Directly by loop position/share of voice, by daypart or audience package, and increasingly programmatically by impressions or plays.
Ask the seller to separate these commercial components:
For digital inventory, establish whether the purchase is direct, programmatic guaranteed, private marketplace or open auction. For static inventory, confirm whether the buy is an individual face, a fixed package or a rotating program.
- Media: the right to display the ad for a stated period, share of voice or number of impressions.
- Production: artwork adaptation, printing or file creation, fabrication, installation and removal.
- Delivery: the exact units, dates, loop position or posting schedule included.
- Verification: proof-of-posting, proof-of-play, photos, play logs and audience reporting.
- Extras: permits, municipal fees, electricity, data, freight, lifts, traffic control, special access, maintenance and reinstatement.
Costs & lead times
A useful early planning range is $250-$20,000+ for a four-week presence in many markets; premium spectaculars and dense metro coverage can exceed this substantially. The final price depends less on the format name than on the specific location, visibility, audience delivery, demand and contract terms.
A practical production planning estimate is No print or posting cost. Allow roughly $300-$5,000 for static or motion asset adaptation; dynamic feeds and approvals can add more. Production may be quoted by the media owner, an OOH specialist or a local fabricator. Compare quotes on the same scope: design, prepress, materials, color proof, finishing, freight, access, installation, maintenance, removal and disposal.
Plan on 1-5 business days for standard static creative once approved; dynamic integrations need longer. Add contingency for brand approval, landlord or transit review, permits, weather, fabrication, technical testing and restricted installation hours. Premium custom work should be scoped before the media contract becomes non-cancellable.
Creative specifications
Pixel dimensions, aspect ratio, file type, file weight, dwell time and motion rules are screen-specific. A common US digital bulletin submission is around 400 x 1,400 px, but never resize blindly.
Before design begins, request a current mechanical or digital specification sheet for every unit. Confirm:
Never assume that two units sold under the same format name accept the same artwork. The operator-issued specification takes precedence over dimensions found in a general guide.
Creative best practices
Make every frame understandable on its own. Avoid small type, long animation builds and calls to action that require typing while driving.
A strong execution normally has a clear hierarchy: one idea, one dominant visual, one short message and unmistakable branding. Use contrast that survives the real environment, not just a bright laptop screen. Mock up the ad from the expected viewing distance and angle. If the audience is moving, test comprehension in seconds; if the audience is waiting, use the extra dwell carefully rather than filling every empty area.
For localized campaigns, use place names, neighborhood cues, nearby landmarks, route context or a genuinely useful local offer when they improve the message. Location relevance supports both human response and clear machine understanding of what the campaign is designed to do.
Campaign fit
This format is a weaker fit when the campaign depends on long explanations, precise individual-level targeting, immediate last-click attribution or production changes that the operator cannot make within the flight.
- Time-sensitive retail
- Events
- Launches
- Weather-triggered messaging
- Multiple creative variants and short campaign flights.
Measurement and KPIs
Ad plays and proof-of-play, estimated impressions, reach/frequency, brand or search lift, web response, visits and outcome studies.
Start with the business objective, then choose the smallest defensible set of KPIs. Delivery evidence is not the same as effectiveness: a posting photo or play log confirms that media ran, while a lift or outcome study asks whether it changed awareness or behavior.
For digital OOH, document how a play becomes an impression and whether multipliers, audience models or venue counts are used. For outcome measurement, agree on exposed and control methodology, attribution windows, deduplication, privacy thresholds and incrementality before the campaign begins.
Buying checklist
- Obtain a unit list with addresses or coordinates, format, orientation, illumination, audience estimates and photos.
- Verify dates, availability, cancellation terms, exclusivity, content restrictions and make-good policy.
- Request exact specifications and an itemized production quote before approving creative.
- Review sightlines or venue context, not just beauty shots supplied in a proposal.
- Define proof-of-delivery, reporting frequency, measurement method and ownership of campaign data.
- Add realistic time for approval, production, installation, troubleshooting and removal.
FAQ
Questions about this format
5 questions
Is this format static or digital?
The answer depends on the inventory. Some suppliers offer only printed or fabricated units, some offer only screens and many offer both. The proposal should identify the technology and delivery model for every unit.
What specifications does this format use?
Pixel dimensions, aspect ratio, file type, file weight, dwell time and motion rules are screen-specific. A common US digital bulletin submission is around 400 x 1,400 px, but never resize blindly. A format nickname is not a production template, so always design to the current specification from the media owner.
Can this format be bought programmatically?
Only digital inventory connected to an eligible supply platform can be transacted programmatically. Static placements and many premium digital takeovers are still negotiated directly. Ask for the supported exchange, deal type, deal ID, bid floor, auction model and reporting fields.
What should a quote include?
It should identify media, production, installation, removal, taxes/fees, exact units, dates, share of voice or impressions, creative changes, reporting, measurement and any optional services. Avoid comparing a media-only quote with an all-in proposal.
How should advertisers compare this format with alternatives?
Compare audience quality, location, reach, frequency, dwell, creative impact, flexibility, production burden, lead time, measurement and total delivered cost. The cheapest face or CPM is not automatically the most effective placement.
