Billboard Advertising Agencies: Do You Need One? (And How to Choose)
Updated 2026-10-18
Short answer: you need a billboard advertising agency if you're running multiple markets, multiple formats, or a large budget and don't have out-of-home expertise in-house. If you're a local business buying a few boards in one city, you usually don't. Buying directly from local operators typically costs less and gives you more control.
What a billboard advertising agency does
An outdoor (OOH) advertising agency handles the campaign from plan to report:
- Strategy: goals, audience, markets and budget
- Planning: choosing formats and locations, building reach and frequency
- Negotiating and buying: getting availability and rates from many operators
- Creative: designing, or adapting, the ads for each format
- Production and installation: coordinating printing and posting
- Proof and reporting: photos of the ads up, impressions and results
Some agencies specialize in out-of-home. Others are full-service or media agencies that buy OOH alongside TV, radio and digital. There are also brokers and marketplaces that sit in between, like Blue Line Media and AdQuick, which source inventory from many operators.
How billboard agencies get paid
Agencies have traditionally been paid through a commission built into the media price: the client is billed the gross rate, and the agency pays the operator a lower net rate and keeps the difference. The commonly cited standard is 15% for most media and 16.67% for outdoor, based on the gross rate (Barron's Dictionary via AllBusiness). Many agencies now charge fees instead of, or on top of, commissions.
Ask any agency to spell out:
- whether they're paid by commission, fee or both
- whether the commission is included in the quoted rates or added on top
- whether production and installation are marked up
When an agency is worth it
| Situation | Agency? |
|---|---|
| Campaign across several cities or states | Yes, usually worth it |
| Mixing billboards, transit, airports and digital | Yes |
| National brand launch with a big budget | Yes |
| No time or in-house marketing staff | Often |
| Want programmatic DOOH with audience targeting | Agency or programmatic platform |
| One local business, one or two boards | Usually not; buy direct |
| Testing billboards on a small budget | No; try self-serve digital or a small local buy |
The case for buying direct
For local campaigns, going straight to the operators who own the boards usually wins:
- No commission on top of the media rate
- Direct negotiation with the people who set prices
- Local knowledge: operators know which boards perform in their market
- Flexibility: independent operators often have shorter minimums and better terms
The catch is legwork: you contact each operator yourself. OOHGuide lists the operators in every market in our city and state guides, and our free quote request sends your request to up to 3 matching local operators at once. See how to buy billboard advertising for all your options.
How to choose a billboard advertising agency
- Out-of-home experience. Ask for recent OOH campaigns in your category and markets.
- Market knowledge. Do they know the local operators and the best boards in your area?
- Transparency on pricing. Will they show you the operators' net rates?
- Independence. Are they tied to particular operators, or do they shop the whole market?
- Measurement. How will they report impressions and results? Can they run attribution or lift studies?
- Creative capability. Billboard design is its own discipline. See billboard design tips.
- Contract terms. Minimums, cancellation, and who owns the creative files.
