Case studies: measurable offline campaigns in Barcelona
Every CARTO campaign leaves a verifiable trail: GPS routes, photo proof, QR scans and a dashboard the client can see in real time. These are the cases that show how the method works in practice.
How we measure every campaign
Zone selection by data
Neighbourhoods chosen by client profile and demographic density, not by availability.
Photo proof on every block
Brand Missionaries photograph each letterbox bank they cover during distribution.
QR on every flyer
The QR code connects the physical flyer to a landing page, offer, or WhatsApp link.
Live dashboard
GPS routes, photos and QR scans visible in real time by zone and time of day.
Published cases
Barcelona Beer Festival: 345 leads in 2.5 days
A flyer distribution campaign with QR tracking in the neighbourhoods surrounding the festival venue. The QR on each flyer measured response by zone and by day. The main result: 345 leads captured in 2.5 days of distribution, with scan data visible in the client dashboard in real time. The key takeaway: better neighbourhood targeting generates more response than increasing flyer volume.
Campaigns in progress
GPS door-drop for a yoga studio in Poblenou (campaign in progress)
A yoga studio based in Poblenou commissioned CARTO to run a GPS-verified buzoneo campaign to attract new students from the neighbourhood. The client remains anonymous during execution. This is the methodology we are applying.
- Streets and blocks within Poblenou selected by residential density and proximity to the studio.
- Brand Missionaries carry out letterbox drops with photo proof of every block covered.
- GPS route logged on every distribution session: every street is traced and verified.
- The flyer includes a QR linked to a first-class offer to measure the response from each zone.
- Live dashboard showing routes, photos and QR scans, plus a weekly report for the client.
Results from this campaign will be published here when it concludes. The QR measures response and scan timing; the GPS route is the precise proof of distribution.
