What Is Connected TV Advertising?
Connected TV refers to any TV that connects to the internet to stream content, whether it’s through Smart TVs, Roku, Apple TV, Amazon Fire Stick, or gaming consoles. Unlike traditional (linear) television, CTV offers a personalized, on-demand experience, and now, a prime opportunity for brands to run precision-targeted ads with smarter household targeting.
At Next Millennium, our content-driven CTV approach is powered by metadata-driven ad placement. This means ads align with the content being watched, improving engagement and performance. Our technology scans show content and episode details to place ads at the perfect moments ensuring alignment with viewer engagement and making the message an organic part of the experience.
Premium Audiences
CTV viewers are not passive, they’re lean-in audiences who intentionally stream content in an ad supported environment. CTV lets brands reach these high-value consumers with custom and seamless messaging with smarter targeting.
Massive Reach + Niche Precision
CTV blends scale with hyper-targeting. Reach millions of viewers or segment by interest, behavior, or household data.
Transparent, Actionable Metrics
Track impressions, view-through rates (VTR), conversions, and platform-specific engagement with real-time dashboards. CTV removes the guesswork.
Omnichannel Journey
With cross-device sync, your CTV ads can influence user behavior across mobile, desktop, and social platforms.
Privacy-First + Brand Safe
All CTV placements from Next Millennium are in brand-safe, pre-vetted environments with compliance-ready targeting strategies and fraud protection built-in.
How to Advertise Using CTV
Define Your Ideal Viewer
Even though the cookie phase out is no longer urgent, smart advertisers aren’t waiting around and first-party data is key in 2025. Start by building a smart, first-party data profile. Then layer on contextual signals and DSP audience segments to focus delivery.
Pro Tip: Combine demographic data with content context for more impactful results. The more precise your targeting, the better your return on investment (ROI).
Choose the Right Content Environment
Ads perform best when placed inside relevant, immersive content. Want your ad in a foodie docuseries? Sports highlight show? Metadata ensures your placement makes sense, and performs. This alignment creates more natural brand moments.
Select Your Media Buying Strategy
- Open Exchange: Broad reach, less control
- Private Marketplace (PMP): Premium inventory and curated environments (learn more)
- Direct Deals: Guaranteed spots and negotiated terms
Next Millennium’s programmatic stack supports all three, optimizing for efficiency, flexibility, and scale.
Track, Analyze & Optimize
Our CTV dashboard helps advertisers monitor metrics like view-through rate (VTR), video completion rate (VCR), frequency caps, CPM, and real-time audience engagement. Smart tracking turns campaign insights into measurable gains.
CTV Success Stories
CTV Pitfalls to Avoid
CTV offers enormous potential, but like any powerful channel, it can underperform if misused. Avoiding these common pitfalls can save your campaign from wasted budget, low engagement, and lost opportunities.
- Over-targeting Too Narrowly
Precision is one of CTVs biggest strengths, however, hyper-specific audience segments can drastically reduce scale and stall your campaign’s performance. Use layered targeting strategies that still offer relevance and reach. - Ignoring Frequency Caps
Without proper frequency controls, you risk bombarding viewers with repetitive messaging, leading to ad fatigue and negative brand perception. Optimize exposure levels across platforms. - Running Generic Ads Across Irrelevant Content
Context still matters. Serving a high-end fashion ad during a gaming livestream? That’s a disconnect. Next Millennium combines metadata-driven placement with premium inventory and high-impact ad formats to ensure your ads appear in brand-aligned, high-quality environments. - Neglecting Cross-Device Optimization
CTV doesn’t live in isolation. A unified view of CTV + mobile + web ensures you’re not double-serving or missing sequential storytelling opportunities. Our platform uses cross-device sync for seamless user journeys. - Failing to Test Formats
Interactive and shoppable ad units are growing rapidly. Brands that stick to static or traditional video formats may miss out on performance lift. A/B testing various formats can unlock new performance ceilings. - Measuring the Wrong Metrics
CTV metrics go beyond impressions. Focus on completion rates, view-through conversions, and lift in brand engagement to gauge true ROI.
CTV Innovation: Interactive & Shoppable Ads
Digiday reports that over 50% of advertisers plan to use interactive or clickable CTV ad formats in 2025. These formats invite viewers to shop, learn more, or sign up, directly from their screen.
Next Millennium supports interactive and shoppable formats designed to improve engagement and drive action.
