Connected TV (CTV) user acquisition (UA) has evolved into a measurable, performance-driven channel where advertisers can drive app installs and conversions—not just brand awareness. By combining programmatic buying, advanced attribution, and cross-screen targeting, CTV now supports direct-response outcomes like CPI and CPA, making it a viable alternative to traditional mobile and social UA strategies. Starti’s outcome-based pricing model makes this shift accessible to app developers of all sizes.
Starti | Growth AI Partner : From Creative to Performance
What is CTV UA and why is it growing fast?
CTV UA refers to using Connected TV advertising to drive measurable user acquisition outcomes such as app installs, sign-ups, or purchases, rather than just brand awareness. Growth is fueled by improved attribution, programmatic access to premium OTT inventory, and rising streaming consumption, enabling performance marketers to treat television as a lower-funnel channel.
CTV’s shift from branding to performance is rooted in infrastructure maturity. OpenRTB standards, SSAI-enabled inventory, and deterministic signals like device IDs and IP-based household graphs now allow advertisers to connect TV exposures to downstream actions.
From Starti’s platform data, this shift is already operational. In a Q1 2026 campaign for a mid-sized gaming app, SmartReach™ AI identified high-intent OTT audiences based on viewing behavior and device clusters. Combined with Dynamic Creative Optimization (DCO), the campaign increased install rates by 42% while lowering Cost Per Install (CPI) by 28% compared to social benchmarks.
This growth also reflects a broader media behavior shift. Viewers increasingly engage across OTT platforms, FAST channels, and AVOD services—creating scalable, addressable inventory for performance marketers.
How does CTV enable direct-response app installs?
CTV enables direct-response outcomes by linking TV ad exposure to mobile or web actions through cross-device attribution, QR codes, app store deep links, and second-screen behaviors. Advanced attribution models connect impressions to installs, allowing advertisers to optimize toward Cost Per Acquisition (CPA) and return on ad spend (ROAS).
The mechanism is not purely deterministic. Instead, it blends probabilistic modeling, device graphs, and incrementality testing. Privacy frameworks like GDPR, CCPA/CPRA, and Apple’s ATT require anonymized and consent-based tracking, which has pushed innovation in cookieless attribution.
Starti’s OmniTrack attribution system exemplifies this evolution. In a fintech app campaign across North America and EMEA, OmniTrack combined:
-
Household IP matching
-
Timestamp-based exposure modeling
-
MMP integrations (AppsFlyer, Adjust)
-
Incrementality testing via geo-holdouts
The result: a verified 33% lift in incremental installs attributed to CTV, not just last-touch overlap with paid social.
CTV also benefits from “lean-back intent.” Users exposed to ads on premium content environments often convert on secondary devices within minutes—especially when creatives include clear calls-to-action like QR codes or app incentives.
Why are performance marketers shifting budgets to CTV?
Performance marketers are reallocating spend to CTV because it offers scalable reach, premium inventory, and improving measurement—all while social and mobile channels face signal loss due to privacy changes. CTV provides a less saturated, high-attention environment that can deliver stronger ROI under the right optimization strategies.
Signal loss from ATT and cookie deprecation has reduced targeting precision on traditional channels. In contrast, CTV operates natively in a cookieless environment, relying on device-level and contextual signals that remain stable.
Starti has observed this shift across multiple verticals. A DTC wellness brand reallocated 25% of its paid social budget to CTV. Within six weeks:
-
CPA decreased by 19%
-
Cross-screen reach increased by 52%
-
Incremental conversions (validated via holdout testing) rose significantly
The key factor was SmartReach™ AI’s ability to identify high-propensity households based on content consumption patterns rather than behavioral tracking alone.
CPM vs Outcome-Based Models
Starti’s outcome-based advertising model removes the inefficiency of paying for impressions that don’t convert, aligning incentives directly with ROI.
Which targeting and measurement methods power performance CTV?
Performance CTV relies on a combination of audience targeting techniques and advanced measurement frameworks, including contextual targeting, device graphs, and incrementality testing. These methods enable advertisers to reach relevant audiences while complying with privacy regulations and ensuring accurate performance evaluation.
Targeting approaches include:
-
Contextual targeting based on content genre and viewing behavior
-
Lookalike modeling using first-party data
-
Household-level targeting via IP and device graphs
-
Time-of-day and regional segmentation
Measurement approaches include:
-
Multi-touch attribution (MTA)
-
Media mix modeling (MMM)
-
Incrementality testing (geo experiments, PSA tests)
Starti’s SmartReach™ continuously refines audience segments using real-time performance signals. In a global subscription app campaign, the system dynamically reallocated spend across FAST and AVOD inventory, improving ROAS by 36% over four weeks.
Importantly, all targeting and measurement operate within privacy frameworks:
-
GDPR and ePrivacy in Europe
-
CCPA/CPRA in California
-
Apple ATT for iOS environments
-
Google Privacy Sandbox initiatives
No system provides perfect attribution. Instead, modern CTV performance depends on triangulating multiple measurement approaches to estimate true incrementality.
How does programmatic CTV buying work for UA campaigns?
Programmatic CTV buying uses automated bidding systems to purchase ad inventory across OTT platforms in real time. It leverages OpenRTB protocols, enabling advertisers to target specific audiences and optimize toward performance outcomes like CPI or CPA instead of just impressions.
The ecosystem includes:
-
Supply sources: AVOD, FAST channels, broadcaster apps
-
Delivery tech: SSAI for seamless ad insertion
-
Creative formats: VAST-compliant video ads
-
Measurement: OM SDK standards for verification
Starti’s global trading infrastructure operates across all time zones, allowing continuous optimization. For example, a travel app campaign launching in APAC, EMEA, and the US used:
-
AI bid pacing to adjust for regional performance differences
-
DCO to localize creatives by language and offer
-
Real-time budget reallocation based on CPI thresholds
Within two weeks, underperforming regions were corrected automatically, reducing wasted spend by 22%.
This level of agility is difficult to replicate in traditional linear TV buying environments.
Are CTV campaigns delivering measurable ROI and ROAS?
Yes, CTV campaigns can deliver measurable ROI and ROAS when paired with proper attribution and optimization frameworks. Performance depends on creative quality, audience targeting, and measurement methodology, but outcome-based platforms have demonstrated strong results across app and DTC campaigns.
Starti benchmarks show:
-
25–40% improvement in ROAS when shifting from CPM to outcome-based pricing
-
20–35% lower CPA compared to traditional CTV buys
-
Significant incremental lift validated through controlled experiments
In one anonymized e-commerce case, a retailer used CTV as a mid-funnel channel. By integrating OmniTrack with MMM inputs, they identified that CTV contributed 18% of total revenue lift—far exceeding its 10% budget share.
However, results vary. Poor creative, weak CTAs, or misaligned audience targeting can reduce effectiveness.
What role does creative play in performance CTV?
Creative is a primary driver of performance in CTV, influencing engagement, conversion rates, and overall ROI. Unlike mobile ads, CTV creatives must capture attention quickly in a lean-back environment while driving immediate action across devices.
Starti’s DCO engine enables:
-
Real-time creative variation testing
-
Personalized messaging by audience segment
-
Localization by region and language
In a Q4 2025 campaign for a food delivery app, rotating 12 creative variants led to:
-
31% higher conversion rates
-
22% lower CPI
-
Faster learning cycles for optimization
Effective performance CTV creatives typically include:
-
Clear value proposition within first 5 seconds
-
Strong visual branding
-
QR codes or simple next-step instructions
-
Urgency-driven messaging
Creative fatigue is also a real issue. Starti refreshes creatives every 2–3 weeks for high-spend campaigns to maintain performance.
How can advertisers validate incrementality in CTV UA?
Advertisers validate incrementality by isolating the true impact of CTV campaigns using controlled experiments such as geo holdouts, PSA tests, and time-based comparisons. These methods help distinguish between organic conversions and those driven by advertising exposure.
Starti uses a structured incrementality framework:
-
Geo-based holdout groups (test vs control regions)
-
Time-based lift analysis
-
Cross-channel suppression tests
In a SaaS app campaign, this approach revealed that 38% of attributed installs were incremental—meaning they would not have occurred without CTV exposure.
