CTV Ads Are Coming for Your Social Budget in SEA

Social media ad costs are doing what ad costs always do when a channel matures: they go up, and the results get harder to defend in a board deck. If you’ve been running paid channels for the last three years, you know the pattern by feel. CPMs creep higher each quarter, attribution windows keep shrinking, and a single algorithm update can quietly undo six months of bid strategy optimisation. Finance wants answers you can’t fully give, because — as the adtech world’s collective obsession with measurement uncertainty keeps reminding us — you’re often arguing about a number that changes depending on when you look at it.

Connected TV is having its performance marketing moment. The question for teams in Southeast Asia isn’t whether to pay attention. It’s how fast to move.

Why Social CPMs Are Losing the Efficiency Argument

The structural problem with Meta and TikTok isn’t the targeting — it’s the auction dynamics. Both platforms run closed ecosystems where demand consistently outpaces quality inventory. As Douglas Karr notes via Martech.zone, the compounding effect is brutal: rising CPMs, contracting attribution windows, and algorithm volatility that punishes optimisation work retroactively. The result is that your blended CAC on social looks fine in month one and quietly deteriorates by month four without a clear signal of why.

For performance marketers managing budgets across multiple Southeast Asian markets, this is amplified. A brand running campaigns across TH, MY, and ID is dealing with three separate auction environments, three different platform-algorithm maturity curves, and — in markets like Indonesia — platform trust dynamics that don’t always mirror Western user behaviour. Social still works. But the efficiency ceiling is visible, and it’s getting lower.

CTV’s Performance Credentials Are Getting Harder to Dismiss

Streaming TV advertising, once the exclusive domain of brand teams with video production budgets and vague awareness KPIs, has genuinely shifted. Platforms built specifically for performance marketers — Vibe being one recent example — are packaging CTV inventory with deterministic audience matching, real-time reporting, and attribution integrations that speak the same language as a search or social campaign. Household-level targeting tied to first-party data, combined with completion-rate signals that social video can rarely match, creates a measurement framework that finance can actually engage with.

The creative barrier is also lower than teams assume. Repurposing existing 15- or 30-second video assets for CTV placements is a legitimate starting point. The production overhead that used to gate brands out of TV is largely gone in the streaming context — what you need is a clean cut and a clear CTA, not a broadcast production budget.

In Southeast Asia specifically, streaming adoption across platforms like Netflix, Disney+, and regional players has accelerated substantially post-pandemic, with mobile streaming consumption in markets like Thailand and the Philippines running well ahead of traditional TV viewing among the 25–44 demographic most brands are chasing.

What CeraVe Understood About Audience Architecture

CeraVe’s decision to bring Carmelo Anthony in as the figurehead of its dandruff campaign isn’t primarily a celebrity endorsement story — it’s an audience architecture story. As Digiday reports, the brand identified that NBA fandom gave it access to a Gen Z audience that is diverse, highly engaged, and notoriously difficult to reach through conventional skincare creative. The channel mix and creative strategy were built backward from the audience signal, not forward from the product.

This is the mental model performance teams should apply to CTV. The question isn’t “should we do streaming TV?” It’s “which audience segment are we currently underserving on social, and does CTV inventory give us a cleaner path to them?” For many brands in SEA, that audience is the 30–45 urban professional who has largely moved their prime-time attention to streaming and is increasingly ad-fatigued on Meta.

The parallel lesson from Honda’s establishment of Honda Digital Innovation India is instructive, even if the geography differs. Honda is investing in owned digital infrastructure because it recognises that customer touchpoints in high-growth Asian markets require direct data relationships — not just rented audience access through third-party platforms. Brands that build first-party data assets now will have significantly better targeting inputs for CTV campaigns in 18 months.

Making the Channel Shift Without Breaking the Model

The practical risk in moving budget to CTV isn’t creative or technology — it’s measurement parity. Your social campaigns have years of benchmarks, optimisation history, and attribution logic baked in. CTV sits in a different part of the funnel for most teams, which means the first 60–90 days will generate data that looks incomparable to your existing channel performance.

A few tactical guardrails worth building in from the start: Run CTV as an incremental budget test, not a reallocation, for the first cycle. Set measurement expectations with stakeholders before launch — agree on which metrics constitute a signal worth scaling. Prioritise platforms that offer third-party attribution integrations over walled-garden reporting. And map your CTV creative to specific funnel stages rather than defaulting to brand-awareness positioning, which is where CTV campaigns go to produce unactionable results.

For Southeast Asian teams, also factor in platform fragmentation. CTV inventory in the region is split across a wider range of streaming services than in Western markets, and programmatic access is less consolidated. Buying through a DSP with verified regional CTV supply paths is meaningfully different from buying direct — know which you’re doing, because the inventory quality and audience verification standards are not equivalent.

Key Takeaways

• Social CPM inflation is structural, not cyclical — building a CTV pilot now positions you ahead of the efficiency curve before competitors bid up that inventory too.
• Audience architecture should drive channel selection: identify which segments you’re underserving on social, then test whether CTV inventory gives you a measurably cleaner path to them.
• Set measurement frameworks with stakeholders before the first CTV campaign launches — retrofitting attribution logic after the fact is how promising pilots get killed by bad data reads.

The harder question underneath all of this: if the platforms you’ve built your performance model on are structurally less efficient each year, and measurement uncertainty is baked into every channel you’re running, at what point does diversification stop being a nice-to-have and become a competitive necessity? The brands stress-testing CTV now will have a meaningful head start on that answer.

At grzzly, we work with marketing teams across Southeast Asia navigating exactly this kind of channel mix decision — building the measurement frameworks, creative strategies, and DSP configurations that make new channel bets actually accountable. If you’re thinking about where CTV fits in your paid media architecture, we’d rather have that conversation before your next budget cycle than after it. Let’s talk
