Connected TV has moved well beyond its early “experimental” phase, but that doesn’t automatically make it a performance channel for every mobile app.
As streaming becomes the default way people consume long-form content, CTV is attracting growing interest from mobile marketers looking for incremental reach and stronger brand presence beyond crowded mobile feeds. At the same time, deeper industry scrutiny has revealed that not all CTV inventory delivers the premium attention it promises, particularly on the programmatic side.
Rather than treating CTV as a must-buy channel, we’ll have a more grounded look at where CTV can add value, where it still falls short, and how it fits into a modern UA strategy without overpromising on performance.
CTV Is Growing Fast But Growth Alone Isn’t the Signal
There’s no question that CTV adoption continues to rise:
- CTV ad spend grew nearly 6% in Q3 (excluding political ads)
- US CTV spending is projected to grow ~14% next year, moderating to ~11% by 2029 (including YouTube)
- CTV impressions grew ~18% in 2024, while ad investment still trails total streaming time
On paper, this creates a familiar narrative: consumer attention is growing faster than advertiser investment.
Historically, that kind of gap has represented opportunity. But in CTV, growth needs to be interpreted carefully. More inventory doesn’t always mean better inventory, and more impressions don’t always translate into more real viewers.
The takeaway for mobile marketers isn’t “CTV is cheap and wide open,” but rather:
CTV is expanding and quality varies significantly depending on how and where inventory is bought.
What CTV Still Does Well for Mobile Apps
Despite its challenges, CTV does offer real advantages when used for the right objectives.
1. A Premium, Distraction-Free Environment (When Inventory Is Legitimate)
At its best, CTV delivers something mobile ads rarely do:
- Fullscreen placement
- No scrolling or feed competition
- Longer, uninterrupted creative exposure
For apps that rely on visual storytelling, emotional hooks, or clear product explanation, this environment can drive stronger brand recall than standard mobile placements.
This makes CTV especially relevant for:
- New category creation
- Brand-led apps (finance, lifestyle, entertainment, subscriptions)
- Products where trust and familiarity matter before install
That said, the “premium screen” promise only holds when inventory is genuinely viewed by real households, a distinction that has become increasingly important in programmatic CTV.
2. CTV as a Mid-Funnel Catalyst (Not a Last-Click Channel)
CTV’s real strength for mobile apps often sits between awareness and action, not at the point of conversion.
Consider common viewing behavior:
- A majority of viewers use a second screen while watching TV
- Ads spark curiosity, not immediate installs
- Search, store visits, and installs often happen minutes or hours later
In this context, CTV works best as:
- A trigger for intent
- A reinforcement layer for other UA channels
- A way to prime users before mobile retargeting or search
This influence is real, but it’s indirect, and it doesn’t always show up cleanly in last-touch attribution.
Measurement Has Improved, But It’s Not Bulletproof
CTV measurement has come a long way. Today, marketers can lean on:
- QR codes
- Cross-device graphs
- MMP integrations
- Probabilistic and deterministic matching
These tools help connect exposure to downstream actions like installs, sign-ups, or purchases.
However, improved measurement does not eliminate uncertainty.
Attribution in CTV is still:
- Heavily modeled
- Sensitive to assumptions
- Vulnerable to distortion if invalid traffic enters the supply path
The risk isn’t that CTV can’t be measured, it’s that results can look convincing even when underlying inventory quality is weak.
The Reality Check: Programmatic CTV Still Has a Fraud Problem
This is the part many CTV conversations skip, but it matters.
Industry reporting has made it increasingly clear that programmatic CTV remains vulnerable to fraud, including:
- Made-for-advertising (MFA) CTV apps
- Spoofed devices posing as smart TVs
- Fake households generating ad requests
- Unauthorized or misrepresented sellers in open auctions
In some cases, more CTV inventory is sold than can realistically be watched.
For mobile marketers, this creates a real risk:
- Budgets can be spent on impressions that never reach real viewers
- Performance metrics can be inflated without driving true incremental impact
- “Premium CPMs” can mask low-quality supply
This doesn’t mean all CTV is unsafe but it does mean that how you buy matters as much as whether you buy.
Where CTV Fits and Where It Doesn’t
CTV Makes Sense When:
✔ You’re looking for incremental reach, not cheap installs
✔ Your product benefits from storytelling and brand context
✔ You want to support mobile UA, not replace it
✔ You can prioritize curated or direct inventory paths
✔ Success is measured holistically (lift, search, downstream impact)
CTV Is a Poor Fit When:
✖ You’re optimizing purely for short-term ROAS
✖ You expect deterministic, last-click attribution
✖ You lack strong creative assets
✖ You can’t control or audit supply quality
✖ You treat CTV like a scaled mobile network
How to Approach CTV Pragmatically in 2025
If you do test CTV, a cautious, controlled approach matters more than scale:
- Favor curated marketplaces and direct publisher relationships
- Use third-party verification and fraud detection
- Watch for abnormal patterns (completion rates, traffic spikes, device anomalies)
- Treat CTV as a learning channel, not an optimization race
- Evaluate success across the full funnel, not just installs
Final Thoughts
CTV in 2025 is neither a silver bullet nor a channel to ignore.
Viewership continues to grow.
Creative impact can be strong.
Measurement is improving.
But programmatic risk remains real.
For mobile apps, CTV works best when positioned honestly:
as a brand and intent amplifier, not a performance shortcut.
If you already understand the basics, the next step isn’t rushing in, it’s deciding whether CTV fits your goals, your risk tolerance, and your broader UA mix.
Used carefully, it can strengthen mobile growth. Used blindly, it can quietly waste budget.
That distinction is what matters most in 2025 (and 2026🙂).
