Outdoor media buying is complex—billboard placements, transit ads, and digital out-of-home (DOOH) networks each have different costs, audiences, and lead times. When you issue an RFP to vendors, being specific about your needs upfront saves time, prevents misaligned proposals, and helps you compare apples to apples. Here's what to request to get proposals that actually serve your business goals.
Define Your Campaign Objectives First
Before sending any RFP, clarify what success looks like. Are you building brand awareness across a metro area? Driving foot traffic to specific store locations? Promoting a limited-time event? Your objective determines which outdoor channels make sense and what metrics matter.
Include target CPM ranges (cost per thousand impressions) or budget caps in your RFP. For traditional billboard placements, expect $2,000–$15,000 per month depending on location and market size. DOOH networks typically cost $800–$5,000 weekly for premium placements in major cities. Being upfront about budget prevents vendors from proposing inventory you can't afford.
Request Detailed Inventory & Audience Data
Ask vendors to provide specific placements with measurable audience metrics. Don't accept vague promises like "high-traffic locations"—demand actual numbers.
Require the following details for each proposed placement:
- Daily traffic counts (foot traffic for pedestrian-focused boards, vehicular counts for roadside billboards)
- Demographic breakdowns (age, income, commute patterns where available)
- Dwell time and visibility metrics (how long viewers are exposed, sightlines, obstruction risks)
- Geographic coverage (exact neighborhoods or routes served)
- Placement dates and availability (construction conflicts, seasonal blackouts, minimum contract lengths)
For DOOH vendors, ask for programmatic capabilities—can they target by time of day, weather conditions, or audience segments? Some networks offer impression guarantees; others sell on a best-efforts basis. Get that distinction in writing.
Specify Creative Requirements & Deadlines
Outdoor media has strict production lead times. Request a detailed timeline from brief to live execution.
Ask vendors to confirm:
- Lead time required before launch (typically 3–6 weeks for traditional billboard, 1–2 weeks for DOOH)
- File specifications and format requirements (resolution, file type, animation limits for digital)
- Proof and approval processes
- Who handles creative design—vendor, your agency, or you
- Revision policies and associated costs
- Installation and dismantling schedules
DOOH vendors should specify refresh rates, whether ads rotate across multiple creative assets, and how frequency capping works if you're running multiple placements.
Ask for Performance Reporting & Verification
Outdoor media attribution isn't as straightforward as digital, but vendors should still offer measurable reporting.
Request:
- Impression delivery documentation (third-party verification, audit reports)
- Foot traffic analytics (for location-based campaigns, tools like foot traffic counters or mobile geolocation data showing visits post-exposure)
- Brand lift studies (if applicable to your budget; surveys measuring awareness lift among exposed audiences)
- Campaign monitoring photos (proof that ads are live and in good condition)
- Real-time DOOH reporting (dashboards showing daily impressions, engagement rates, if available)
- Frequency reports (how many unique vs. repeat impressions you're getting)
Ask whether they use Nielsen, Geopath, or proprietary measurement tools. Different vendors use different standards, so knowing the methodology helps you compare fairly.
Include Contract & Support Terms
Vendor proposals should address legal and operational details:
- Payment terms (deposits, payment schedule, penalties for early termination)
- Weather/maintenance guarantees (what happens if a billboard is damaged or obscured during your contract)
- Exclusivity clauses (are competitors blocked from adjacent placements?)
- Cancellation or rescheduling policies (what flexibility exists if your campaign needs adjustment?)
- Account management (who's your primary contact, response time for issues?)
Request references from recent campaigns in your industry or geography. Ask for case studies or previous client results, especially if you're committing to a six-figure spend.
Comparing Proposals Effectively
Once proposals arrive, create a comparison matrix: list each vendor, placements offered, total cost, audience reach, lead time, and reporting capabilities side by side. Platforms like Mercoly help you compare and find trusted outdoor media buying providers in one place, streamlining vendor evaluation.
Score vendors on criteria that matter most to your campaign—budget efficiency, audience alignment, timeline feasibility, and reporting depth. The cheapest option isn't always the best if it sacrifices reach or measurement.
Frequently Asked Questions
Q: What's a realistic timeline for launching an outdoor media campaign? A: Traditional billboard campaigns need 4–6 weeks from approval to live execution; DOOH campaigns can launch in 2–3 weeks if assets are ready. Always add 1–2 weeks for RFP review and vendor selection.
Q: How do I know if a vendor's audience data is accurate? A: Verify they use third-party metrics like Geopath (standardized traffic counting) or Nielsen outdoor ratings. Ask for audit reports and cross-check traffic counts against multiple vendors in the same location—numbers should align.
Q: Can I negotiate outdoor media contracts, or are prices fixed? A: Prices are negotiable, especially for longer commitments (6+ months) or multiple placements bundled together. Bulk discounts of 10–20% are common; flexibility increases during off-peak seasons.
