OOH CPM Arbitrage and Where to Find Deals

Billboards at $0.75 CPM. Streaming TV you can actually measure. Tim Rowe breaks down how to blend OOH + CTV to drop blended CAC, spark geo-lift, and build “living-room” brand equity—without massive budgets.

Streaming has turned TV into a performance channel you can buy, cap, and measure like digital—often at CPMs rivaling or beating social. Tim explains how their ad server + pixel connect living-room exposure to down-funnel actions, with many brands seeing $3–$4 cost per visit and 3–4× higher conversion vs other traffic sources. On OOH, the overlooked arbitrage is static or digital boards priced like real estate: win by buying the biggest formats in the largest markets at the lowest biddable entry price, then engineer earned media (social virality) and geo-lift. Start with ~$5k for a real CTV test (smaller tests can still work as an add-on), measure blended CAC, branded search, and market-level lift, and let creative—not hyper-granular targeting—do the heavy lifting.

What You’ll Learn

• Why streaming made TV relevant again—and cheap ($1–$2 CPMs in some geos).
• How to attribute TV exposure → search → site visit → purchase within a 48-hour view-through window.
• The out-of-home (OOH) arbitrage: buying big signs in big markets for sub-$1 CPMs.
• How OOH + CTV lower blended CAC and lift branded search in target geographies.
• Practical first tests: budgets, pixels, frequency caps, creative, and geo measurement.
• Event playbooks: digital billboard trucks, rideshare screens, street teams, and QR flows.
• Targeting reality: on CTV, less targeting often wins—use creative as the filter.
• Retargeting on TV (yes): pixel site traffic and follow with CTV/audio/display.

Playbooks & How-Tos

1) Fast OOH Test (2–4 weeks)

• Pick 1–2 large markets your sales team targets.
• Buy largest formats you can afford (static or digital) at the lowest CPM; test via https://www.blipbillboards.com/
  (entry-level) or via PMPs/direct with operators.
• Creative: one bold claim + large logo + simple URL/QR. Design for 0–3 second read.
• Measure: branded search & direct/organic sessions from those geos; compare pre/post.

2) Streaming TV (CTV) Starter

• Pixel your site (for attribution + retargeting).
• Launch a broad geo campaign; cap frequency; rotate 1–2 :15–:30 creatives.
• Budget: aim for $5k to reach statistical signal; smaller ($1.5–$2k) still useful as a display-like add-on.
• KPI: cost per visit ($3–$4 is common in Tim’s data), conversion rate lift vs other traffic, branded search lift, blended CAC shift.

3) Event Swarm Tactics

• Digital billboard truck looping near venue entrances all day.
• Rideshare TV for the event radius; add a QR to capture emails or drive an offer.
• Street team + product samples or demo cards; sponsor a coffee cart beside the venue.

Key Takeaways (Skimmable)

• CPMs: OOH can hit ~$0.75; CTV often $1–$2 in the right geos.
• Attribution: Use a 48-hour view-through window from TV exposure to on-site actions.
• Blended CAC: Expect downstream CAC reductions across channels from brand lift.
• Targeting: On CTV, broader = cheaper CPMs and often better performance; let creative and 1P audiences do the work.
• Budget: $5k is a solid first test; smaller tests still demonstrate directionality.
• Creative: Be bold; engineer shareable moments to multiply paid with earned.
