Economic impact — with the math on the table
Drag the assumptions. Black-box platforms won’t show you these dials.
60 clicks-to-book × 20% booking rate × 2.0 nights × $205 ADR = $4,920 lodging revenue floor on $1,000 spend
$4,920
Lodging revenue floor (bookings only)
4.9 : 1
Hard-dollar ROAS floor
62 : 1
Same result, black-box methodology*
*Applies the incumbent vendor’s own multipliers (destination spending × visitor days) to the identical
campaign — shown so boards can compare like for like. The floor is what you can bank on; the starred
number is what you’re being sold elsewhere.
Why DMOs switch
| Black-box platforms (Datafy & similar) | Postcard | |
|---|---|---|
| Can your board audit the numbers? | No — modeled phone-location panel | Yes — your GA4, your ad accounts, public tax records |
| Who grades the ads? | The platform that sold the ads | Independent of media — we don’t serve ads |
| Ground truth | Estimated trips & modeled visitor spend | Lodging-tax dollars the city actually collected |
| Methodology | Proprietary | Open formula, adjustable assumptions (above) |
| Attribution coverage | Ads served through its own DSP | Every channel — paid, organic, PR, email |
| Data handling | Location data brokered from phones | Reads with your logins; nothing brokered, nothing resold |
| Annual cost | $35–85K+ (platform + bundled media) | A fraction — no media bundle required |
