What this covers
|
An outdoor proposal is a short document that looks simple and is not. It contains a handful of figures, most of which describe the road rather than your campaign, and it leaves out two costs that will land on you regardless.
Here is how to read one.
“Estimated Impressions” or “Daily Effective Circulation”
The headline figure, and the one most advertisers anchor on.
It is a measure of traffic passing the structure, adjusted in the better versions for things like visibility and which direction the face points. It is a reasonable description of a road.
It is not a description of your audience. It does not distinguish a commuter who lives four miles away from a driver crossing the state, and for a local business those are not remotely the same person.
The question to ask: what proportion of this traffic originates within my service area? A vendor who has thought about it can answer directionally. One who cannot is quoting you the road.
“Share of Voice” or “Spots per Loop”
On a digital face this is the figure that actually determines your exposure, and it is frequently buried.
A digital board runs a loop of advertisers, each holding the screen for around eight seconds. If six advertisers share the loop, you are on screen for roughly one pass in six. A commuter passing twice a day sees your creative once or twice a week rather than ten times.
That is not a problem, it is how the format works. It becomes a problem when an advertiser reads the impressions figure, which counts every vehicle, and assumes their creative was in front of all of them.
The question to ask: how many advertisers are in this loop, and what is my share? Then divide the impressions figure by it, because that is your actual number.
The Rate, and What Period It Covers
Outdoor is quoted per face, per four-week period. Not per month, which is a different length, and the difference matters when you are comparing quotes.
The questions to ask: is this rate held if I commit to consecutive periods, and what does it become if I commit to a quarter? Operators discount meaningfully for a run and for booking ahead, and the first number quoted is rarely the last one.
Production, and Whether It Is in There
On a digital face there is nothing to print, so production is design only.
On a static bulletin the vinyl must be printed to that board’s dimensions and a crew scheduled to install it. That is a separate cost, it is weather dependent, and it is occasionally left off a proposal entirely so the comparison against digital looks closer than it is.
The question to ask: is print and install included, and what is the lead time on it?
The Map, and What Is Missing From It
Good proposals include a map with the structures marked. Look at what is not marked.
You want the direction each face points, because a board catching the evening commute home is a different asset from one catching the morning run out. You want to know what sits in front of it. And you want the specific structure identified rather than a package of unnamed positions, because a package lets the vendor fill it with whatever is unsold.
The question to ask: which exact structures am I buying, facing which way?
The Two Costs the Proposal Will Not Contain
Artwork designed for the format. Seven words or fewer, contrast over color, one idea per face, produced to that board’s specification. This is a real design job and it is not resizing a social graphic. A proposal quotes media, not creative.
Whatever the board points people at. This is the larger of the two and it never appears anywhere.
A billboard creates demand; it does not capture it. Somebody sees your name at speed, remembers it that evening, and searches. If what they find is a stale business profile and a slow website, the campaign worked and the customer went to a competitor who was easier to find.
Budgeting for the board without budgeting for the destination is the most expensive omission in outdoor advertising, and it is invisible until the campaign is already running.
What a Good Proposal Looks Like
Named structures with direction of travel. Traffic figures with a note about composition. Share of voice stated plainly for digital faces. Rate per face per period, with the consecutive-period rate beside it. Production broken out. Lead times stated.
And ideally, a vendor willing to tell you a face is wrong for your business. That happens less often than it should, and it is the strongest signal in the whole conversation.
The same reading applied to a larger metro is set out under billboard advertising in Kansas City with the corridors named and what each is worth. The business profile shows the market it is written from, and there is more on what drives the quoted price. Our own office is a marketing agency in Springfield, Missouri and we buy these campaigns for trades across the region.
Line by Line Through an Outdoor Proposal
Proposals from media sellers follow a format. Knowing what each line is and what it omits turns a document designed to be accepted into one that can be questioned.
| Line item | What it means | What to ask |
| Impressions or DEC | Estimated daily effective circulation | Measured how, and in which direction of travel |
| Rate | The media cost for the period | Is production included, and is it negotiable late in a cycle |
| Flight dates | When the creative runs | What happens to unsold inventory before it |
| Share of voice | On digital, how much of the loop you hold | How many advertisers share the face |
| Production | Design, print and installation | Quoted separately or bundled |
The share-of-voice line is the one to press on for a digital buy. A face rotating between six advertisers is a different product from one rotating between three, and the rate rarely reflects the difference as cleanly as it should.
The Flags Worth Walking Away From
| What you see | Why it matters |
| A rate quoted before you describe your customers | The proposal is inventory-led, not audience-led |
| Impressions with no direction of travel | Half that traffic may never face the board |
| No production line at all | It will appear later, after commitment |
| Pressure tied to a deadline that is not yours | Unsold inventory, dressed as scarcity |
| Reluctance to name which faces are weaker | An honest seller has a worst board and will say so |
That last row is a genuine test. Every inventory has faces that underperform, and a seller who concedes which ones is worth more than one whose entire book is described as premium.
What a Good Proposal Contains That Most Do Not
A proposal worth signing names the audience before it names the boards. It states which roads the target customers use, why those roads, and which faces on them are worth the money. It also says what the campaign cannot do.
In a larger metro this matters more, because the number of available faces makes it easy to assemble an impressive-looking schedule that reaches the wrong people efficiently.
One Number to Add Yourself
Before signing, work out your own figure: cost per period divided by your share of voice, divided again by your rough estimate of what proportion of that traffic is local.
It will be a much smaller and much less impressive number than the one on the proposal. It is also the only one that describes what you are actually buying.
Two further points apply once a schedule is on the table. The first is that a proposal built around a package rather than a route is usually inventory the seller needs to move, bundled to look like a plan. Ask for the faces individually priced and the picture changes quickly.
The second is that a larger metro rewards concentration over spread. A schedule with one face on each of six corridors reaches a wide audience thinly, which buys reach and almost no frequency. The same budget on two corridors that the target customers actually use buys the repetition that makes a name stick. Sellers rarely propose the concentrated version, because a spread schedule uses more of their inventory.
One last habit worth building. Keep every proposal you are sent, including the ones you decline, and compare them across a year. Rates move, inventory changes hands, and the same face can be described very differently by two sellers in the same quarter. A buyer with a file of past proposals negotiates from evidence. A buyer working from memory negotiates from whatever the current document says, which is precisely what it was written to achieve.
A proposal is a sales document. Read as one, it becomes a useful starting point rather than a decision already made on your behalf.
