How to Share a Billboard Inventory Map with Advertisers

Sending an advertiser a spreadsheet of available billboard locations — with addresses, facing directions, and daily traffic counts in columns they have to decode — is asking them to imagine geography instead of showing it to them.

OOH advertising is a geographic medium. The advertiser buying a billboard program isn't buying a list of structures; they're buying coverage at specific locations on roads their customers travel. When you show them that coverage on a map, the sale becomes a planning conversation rather than a feature list review. When you share the same map with their agency's media planner, the agency can overlay their client's target audience data against your available inventory and build a program that serves the brief — a conversation that couldn't happen with a spreadsheet.

Atlas gives OOH sales teams the ability to publish curated inventory maps for specific advertisers and agencies — showing exactly the structures relevant to each prospect's campaign, with the level of detail appropriate for an external audience, accessible via a shareable link that doesn't require any software installation.

Here's how to build advertiser-facing maps that accelerate the sales cycle.

Why Map-Based Proposals Close Faster Than Spreadsheet Lists

An advertiser who can see your inventory geographically can make a faster and more confident buying decision than one who can't.

An advertiser who can see your inventory on a map is an advertiser who can say yes faster — because the spatial case for the buy is visible, not imagined.

Step 1: Configure a Public or Shared Inventory View

Your internal inventory map has data that external audiences shouldn't see:

• Create a public view in Atlas that includes only the fields appropriate for advertiser visibility: format, dimensions, facing direction, daily traffic count, illumination, and availability status — without internal fields like lease rent, maintenance history, permit details, or rate card information
• Style the public view for advertiser readability using simple color coding — available structures in green, recently posted or coming available in blue — rather than the full operational status palette your internal teams use
• Configure the public layer as read-only so viewers can explore the inventory but cannot modify any records
• Set up the view filter to show only currently available inventory by default — advertisers don't need to see your sold inventory; they need to see what they can buy
• Test the shared view from an incognito browser and from a mobile device to confirm it's accessible and readable without software installation or login requirements

Step 2: Build Curated Proposal Maps for Specific Campaigns

The general availability map is a starting point; the proposal map is what closes the deal:

1. Filter the inventory map for structures that match the advertiser's brief — format, geographic area, traffic threshold, facing direction, or proximity to specific points of interest
2. Build a curated view showing only the proposed structures with a visual presentation layer that highlights their geographic positioning relative to the advertiser's key locations — their stores, their competitor locations, their target demographic zones
3. Add context layers relevant to the advertiser's category — retail locations for a retail advertiser, major commuter routes for a daily-need product, event venues for entertainment advertising — that visually demonstrate why the proposed locations serve the campaign objective
4. Include structure-level callouts at key positions showing format, dimensions, daily traffic, and availability window — the information an advertiser needs to evaluate each structure without opening a separate document
5. Save the proposal map as a named view that can be shared via link and updated if the proposed program changes — so the advertiser always sees the current state of the proposal, not a PDF snapshot from when it was first sent

Step 3: Enable Direct Advertiser Map Exploration

Beyond proposals, give advertisers a way to explore inventory independently:

• Publish a market-level public inventory page on your company website showing currently available structures on an interactive map — the equivalent of your "inventory browser" that lets agencies scope programs without needing to contact a sales rep first
• Add filtering tools for the public inventory view — filter by market, format, facing, or traffic threshold — so media planners can self-serve their initial program scope before requesting a formal proposal
• Include contact integration on the public inventory page so a planner who finds a program they like can submit a request to the sales team directly from the map — capturing intent while it's active rather than requiring a separate contact step
• Track inventory page engagement to identify which markets and formats receive the most advertiser map views, informing sales focus and inventory development priorities

Step 4: Create Campaign Confirmation Maps for Closed Business

Once a campaign is sold, the map continues to serve the advertiser relationship:

• Update the confirmed campaign map to show sold (not just available) structures with the confirmed posting schedule, production specifications, and location details — the campaign confirmation document that replaces a location list PDF
• Include photos for each confirmed structure showing the primary read approach — the most frequently requested item in any OOH campaign confirmation, now accessible from the map record
• Share the campaign map with the advertiser's agency and internal teams as the authoritative reference for the campaign geography — so the creative team knows what size structures they're producing for and the media team has the location documentation their billing systems require
• Track posting confirmations by updating each structure's status to "Posted" with a photo of the installed creative, giving the advertiser and agency a real-time view of campaign deployment across their confirmed locations

Step 5: Build Proof-of-Performance Documentation from the Map

Post-campaign accountability maps build long-term relationships:

• Generate a posting confirmation report from the campaign map showing every structure in the buy, its confirmed posting date, and a photo of the installed creative — the standard proof-of-performance document that agencies require for client billing and campaign verification
• Document uptime for digital campaigns using the structure-level operational status history, showing total impressions delivered by display and any dark time that triggers makegoods or credit
• Include engagement data for digital campaigns where content management system data is available — plays, dwell time, audience attribution — presented in the context of the campaign geography
• Package the proof-of-performance as a shareable campaign report linked to the campaign map rather than as a PDF that requires re-opening if the advertiser has questions about a specific location

Step 6: Use Advertiser Map Engagement to Improve Sales

Advertiser interactions with your inventory maps are sales intelligence:

• Track which structures appear most frequently in advertiser proposal maps and exploration sessions — high-interest structures that aren't selling quickly may be priced too high or have availability windows that don't match buyer demand
• Monitor which markets generate the most external map engagement — strong map engagement in a market with below-average revenue suggests a sales or pricing problem, not a demand problem
• Use proposal conversion rates by map type — proposals with interactive maps vs. proposals without — to quantify the sales cycle impact of map-based selling if you need to make the internal case for the investment in the workflow
• Collect advertiser feedback about the map proposal experience — what information they wished was included, what format they found easiest to use — to improve the presentation for future proposals

Use Cases

Sharing a billboard inventory map with advertisers matters for:

• OOH sales teams at companies where the current proposal process involves sending Excel spreadsheets and PDF location maps, and where showing an interactive map to advertisers and agencies would accelerate the buying decision
• OOH operators competing against larger platforms that can provide programmatic inventory browsing to agencies — a map-based proposal capability levels the playing field for independent operators competing for agency-managed media budgets
• Premium OOH operators building long-term relationships with major advertisers who expect transparency, accountability, and campaign documentation that reflects the strategic investment their OOH programs represent
• Multi-operator OOH networks that need to present combined inventory from multiple participating operators to agencies as a unified market buy — a combined map that shows the full market reach of the network is far more compelling than separate proposals from each operator
• Transit and street furniture OOH programs where the distributed, high-density nature of the inventory makes map-based visualization particularly powerful for demonstrating market coverage and audience saturation to city-wide campaign advertisers

It matters for any OOH organization where the geographic nature of the product is being communicated to buyers in a non-geographic format — and where showing the map would close the gap between what the inventory offers and what the advertiser understands it offers.

Tips

• Show the map before the rate card — advertisers who understand the geography buy the geography; advertisers who see the rate card first evaluate the price before they understand the value
• Include competitive context in proposal maps — showing an advertiser their proposed buy alongside competitor structure locations demonstrates the coverage advantage of your inventory relative to what they'd get from the competition
• Use the same map for the proposal and the campaign confirmation — a consistent map interface that the advertiser interacts with from initial proposal through final proof-of-performance creates a professional, coherent campaign experience
• Don't share the full inventory in proposals — a proposal that shows 400 available structures in a market is overwhelming; a proposal that shows the 12 structures best-suited to the advertiser's brief is compelling
• Archive proposal maps for past campaigns — the proposal map that closed a client's Q4 campaign is useful context for the Q4 proposal you'll send them the following year, showing what was in their last program and what's changed

Map-based billboard selling in Atlas turns OOH proposals from documents that explain a location-based product to presentations that show it — and what gets shown gets sold faster.
