Connected TV (CTV) has quickly become one of the most powerful environments for storytelling. It is immersive, high attention, and increasingly measurable. The CTV audience has grown to over 129 million users in 2025, marking an 85–87% year-on-year surge, driven by the rise of OTT consumption and smart TV adoption.
At the same time, mobile continues to dominate as the device where decisions are made and actions are completed, with 93% of Indians consuming video on mobile devices, while 71% still engage with TV screens. This makes cross-screen behavior the norm rather than the exception.
The real opportunity lies in how seamlessly these two screens work together. Here’s a checklist of creative strategies you need to make CTV ads that convert on mobile.
The foundation of a high-performing CTV campaign lies in choosing formats and durations that align with both storytelling and conversion goals.
While 30-second ads offer a balanced canvas for narrative and action, 15-second formats are effective for reinforcing messages and driving frequency, especially when supported by mobile retargeting. Longer formats, such as 60 seconds, create room for deeper storytelling but require multiple engagement cues throughout the ad.
Layering QR-enabled creatives or interactive formats within this mix allows brands to move beyond passive viewing and introduce clear pathways to mobile action.
Build Creatives for the Big Screen, Not as an Extension of Mobile
CTV requires a fundamentally different creative approach compared to mobile or social.
The large screen, viewing distance, and lean-back experience demand bold visual hierarchy, uncluttered frames, and highly legible typography. Standard 16:9 formats should be designed with safe zones to avoid UI overlaps.
When QR codes or calls to action are introduced, their placement, size, and contrast become critical to usability.
Treating CTV as a distinct creative environment, rather than repurposing mobile assets, significantly improves both comprehension and engagement.
Campaign analysis across streaming platforms consistently shows that optimized CTV creatives drive higher completion rates and stronger brand recall, resulting in a more qualified audience for mobile conversion.
QR codes are most effective when they are integrated into the storytelling rather than added as a final prompt. Its role is to create a seamless bridge between the TV and mobile experience. This requires thoughtful execution across timing, placement, and incentive.
Keeping the code visible for a sustained duration, positioning it consistently within the frame, and pairing it with a clear value exchange, such as an exclusive offer or app-led benefit, encourages interaction without disrupting the viewing experience.
When supported by deep linking, QR-driven journeys can take users directly into relevant in-app or mobile web experiences, reducing friction and improving conversion outcomes.
Structure the Ad to Sustain Attention and Prompt Action
CTV’s high view-through rates create an opportunity to build layered storytelling within a single ad. Rather than concentrating all messaging at one moment, effective creatives distribute key elements across the timeline. They introduce the brand and hook early, develop the narrative through the middle, and reinforce action toward the end.
For longer formats, repeating visual cues or reintroducing the QR code at key intervals helps maintain engagement as attention shifts.
This structured approach ensures that the ad captures both early attention from second-screen users and sustained engagement from viewers who watch through to completion.
Connect the CTV Experience Seamlessly to Mobile
A CTV ad is not a standalone touchpoint. It is the starting point of a broader cross-device journey. The transition to mobile must feel consistent and intuitive. This includes aligning visual identity, messaging, and offers across CTV creatives, mobile ads, and landing environments.
For app-first brands, deep linking directly into specific in-app destinations shortens the path to conversion.
How mDSP’s CTV App Sync Works
CTV App Sync connects CTV exposure with measurable app outcomes across screens. It uses the big screen to build attention and intent, then tracks how that exposure drives installs and downstream app activity.
1. Impression Tracker Setup
The measurement partner provides impression trackers built for TV ads or prepared for IP matching. This establishes the foundation for accurate cross-screen measurement.
2. CTV Ad Delivery and Signal Capture
The ad is served on connected TV, and the household IP address is sent to the measurement partner through the tracker. In CTV app conversion flows, TV native ID can also be passed for deterministic attribution where available.
3. User Action Across Screens
After seeing the CTV ad, the user takes action by downloading the app on mobile or by installing it directly on CTV. The measurement partner then attributes the resulting app events to the ad exposure. For CTV app conversions, attribution occurs deterministically when possible using TV-native ID, and through IP matching when not.
4. Real-Time Measurement and Assisted Conversions
Real-time conversions are counted through the measurement partner, and assisted conversions are also captured when household matching is found, but direct attribution is not. Converted users can also be automatically suppressed.
5. Creative and Conversion Readiness
To support stronger conversion performance, campaigns can make use of high‑quality videos, engaging creatives, voiceovers, QR codes displayed throughout the full duration of the ad, strong calls‑to‑action such as ‘Play,’ ‘Download,’ or ‘Scan,’ and official app store icons for easier identification. Creative production support is also available.
Building Seamless Journeys Across Screens
As CTV advertising continues to evolve, creative strategy is becoming central to unlocking its full potential. The combination of format, structure, and cross-screen continuity determines how effectively attention is converted into action.
High-performing CTV ads increasingly follow a composite creative approach, where multiple conversion cues work together within a single frame. This includes strong visual storytelling, persistent QR codes, clear calls to action, app store signifiers, and supporting elements such as voiceovers and subtitles.
When these elements are thoughtfully integrated, they create a cohesive experience that guides the viewer naturally from awareness to action.
The result is a CTV strategy that builds multiple pathways for engagement and delivers stronger mobile conversion outcomes.
