The economics of owned vs. rented DOOH

The DOOH (digital out-of-home) market in South Africa is fragmented between two business models: owned networks (premium locations, limited inventory, high CPM) and rented networks (aggregated sites, high volume, lower CPM). Most B2B buyers default to rented networks — it's cheaper, easier to scale, lower risk. But the unit economics tell a different story.

Owned DOOH locations command 25–40% CPM premiums over rented networks, because they filter traffic: a screen in O.R. Tambo International attracts 65,000 premium commuters daily, versus 8,000 mixed-demographic visitors at a secondary shopping mall. Premium B2B buyers — financial services, luxury goods, enterprise software — have historically accepted the CPM premium because the audience quality justifies it.

But here's where the unit economics flip. Owned network math: 8–12 premium metro locations at 200,000 impressions per month each yield 1.6–2.4 million monthly impressions at a CPM of R45–R65, for R72,000–R156,000 per month. Rented network math: 200+ locations at CPM R28–R38 deliver 8–12 million impressions for the same total budget — 3–4x the impressions, but across fragmented, lower-quality inventory. Rented networks look cheaper per impression. They are. But conversion efficiency per qualified prospect is typically 40–60% lower because audience quality is diluted.

Where RMH's thesis differs: most DOOH analyses focus on impressions and CPM. Our investment thesis focuses on venue quality and audience confidence. An airport screen reaches a known demographic — business travellers, high-net-worth individuals, decision-makers — the venue itself is a quality filter. A shopping mall screen reaches a mixed audience that the venue doesn't filter, it accumulates. For B2B buyers, venue quality compresses the consideration cycle.

The attribution model matters too: most DOOH campaigns measure impressions, estimated reach and foot-traffic correlation — proxy metrics that don't measure actual prospect engagement. RMH's model introduces venue-to-web tracking (geofencing owned locations to measure website visits within 24 hours of exposure), prospect confidence scoring (an impression on someone who chose to be in that venue is higher-confidence than one on a passer-by), and cross-channel attribution (owned venues allow cleaner attribution because the audience is known and segmentable).

The continental play: South Africa has three tier-1 airports, Nigeria has four, Kenya has two. A Pan-African B2B company can build a DOOH strategy concentrated on owned airport networks across these hubs — reach that is continental, an audience that is filtered, and attribution that is cleanable. Rented networks cannot match this precision, even at three times the volume.

The unit economics, clarified, for a B2B company with a four-month sales cycle and R15,000 average deal size: an owned DOOH strategy across 8 premium locations at R120,000/month spend delivers roughly 320 qualified prospects at a 20% confidence rate, a cost per customer acquisition of R11,720 against a R45,000 lifetime value — a 3.84x ROAS. The equivalent rented DOOH spend across 150+ mixed-quality locations, at a 5% confidence rate, produces a cost per customer acquisition of R46,880 against the same R45,000 lifetime value — a 0.96x ROAS, effectively loss-making.

The rented DOOH market is designed for volume plays — FMCG, automotive, retail. The owned DOOH market is designed for precision plays — B2B, luxury, finance. Most B2B buyers treat DOOH as a volume channel; they should treat it as a precision channel: identify owned networks in your target markets before you think about impressions, build venue-to-web attribution, stack DOOH with email and digital retargeting, and negotiate long-term owned placements rather than one-month bookings. The owned DOOH market in South Africa is undersized relative to rented networks — but for B2B companies with premium price points and long sales cycles, it's the most efficient channel available.
