What is OTT & Connected TV Advertising Services?
OTT/CTV Advertising: Video advertising delivered via streaming services (Over-The-Top, or OTT) to Connected TV devices (smart TVs, streaming sticks, gaming consoles) — enabling TV-quality video ads with digital-level audience targeting and attribution.
OTT/CTV campaigns are executed through programmatic platforms (The Trade Desk, DV360, Amazon DSP), direct publisher deals with streaming networks, or specialized CTV-focused DSPs. Agencies build audience segments using first-party data, demographic targeting, and behavioral signals — then optimize toward reach, frequency, and completion rate goals with post-campaign attribution using pixel-based or panel-based measurement.

Frequently Asked Questions
What is the difference between OTT and CTV?
OTT (Over-The-Top) refers to streaming content delivered over the internet, bypassing traditional cable/satellite. CTV (Connected TV) refers to the device — smart TVs, streaming sticks, gaming consoles — used to watch OTT content. In advertising, the terms are often used interchangeably.
How much does CTV advertising cost?
CTV CPMs typically range from $25–$50 for broad audience segments, with premium inventory on top streaming services running $40–$80+ CPM. Campaigns typically start at $10,000–$25,000 minimum for meaningful scale.
Can I target specific audiences on CTV?
Yes — CTV enables demographic, interest, behavioral, and custom audience targeting using household IP data, device graphs, and first-party data matches. This precision is impossible with traditional linear TV.
How do I measure CTV advertising effectiveness?
Track video completion rate (VCR), reach and frequency against target audience, branded search lift, website visit lift from exposed vs. unexposed households, and for e-commerce, pixel-based attribution connecting TV exposure to online purchases.
