Buying connected TV in Latin America: what works differently here

Almost all CTV literature is written for the United States, and it transfers badly. The channel is the same — ads inside streaming apps on TV screens — but in Latin America four things change, and they decide whether a campaign works: what supply you can actually reach, what currency you pay in, how it is invoiced, and what you can measure.

For the channel fundamentals, see the CTV advertising guide. This is what gets added when the market is the region.

Demand is not the problem

Latin America will be the world's second-fastest-growing region in digital ad spending in 2026, per eMarketer. Smart TV and ad-supported service penetration have grown quickly in the region's large markets, and advertisers are paying attention.

What has not kept pace is the buying infrastructure. That is where plans copied from a US case study break.

Difference 1: supply varies a lot by country

This is the most important and the most underestimated. The inventory available programmatically in one country in the region bears little resemblance to another, both in volume and in what is auctioned versus sold directly.

What to check	Why it matters
Which streaming publishers and apps are reachable via deal in that country	It sets the ceiling on campaign quality
How much local inventory moves through auction versus direct sale	If most is sold direct, a programmatic-only plan will not reach it
Whether the formats you planned exist in that market	Format availability is not global
How deep the supply is at the frequency you need	Thin supply at high frequency concentrates on few households

The practical rule: never promise reach in a plan before verifying availability for that specific country. This is not a formality. It is the difference between a campaign that delivers and one that paces at 40% while nobody can explain why.

Difference 2: currency and billing

This is the region's real operational blocker, and it has nothing to do with advertising.

• Platform spend is usually denominated in dollars while the client's budget is in local currency. A devaluation mid-flight changes the plan.
• Local payment terms are long. Fronting platform spend for clients who pay at 60 or 90 days is a financing problem dressed as a media problem.
• Enterprise contracts ask for committed volume sized for larger markets. A serious regional advertiser can fail to qualify on size rather than on quality.

The first two are solved by who carries the platform cost. The third, by the access route — covered in DV360 access from Latin America.

Difference 3: measurement has to be simpler

The panels and cross-media measurement solutions available in mature markets are not available the same way across the region. Designing measurement as if they were is how you arrive at the wrap meeting with nothing to show.

What does work here:

1. Geo holdout. Leave cities or provinces unexposed and compare. The most robust tool available, and the least used.
2. Household reach and frequency from the DSP's own reporting, which does not depend on local vendors.
3. Movement in branded search and direct traffic in exposed areas.
4. Publisher and app level delivery, which doubles as your quality control.

What not to promise: brand lift with sample sizes that are not obtainable, or person-level attribution in a channel whose unit is the household. Measurement detail is in CTV measurement and attribution.

Difference 4: YouTube weighs differently

Across much of the region, YouTube is a far larger share of video consumption than in the US, and it is watched on the television. A regional CTV plan that leaves it out is leaving out the largest surface — and it is only buyable through Google's stack. That is covered in YouTube CTV advertising.

A planning mistake that keeps repeating

The most expensive one in the region is planning several countries at once on one country's budget. The logic sounds reasonable — "we are a regional brand, it should look regional" — and the result is a frequency curve too thin to change behaviour in any of the markets, plus data split into pieces too small to learn from in any of them.

The uncomfortable alternative works: pick one market, do it properly, measure it with a holdout, and only then replicate with evidence in hand. One country with real reach and frequency teaches more than five countries with token presence, and leaves you a case of your own rather than a borrowed benchmark.

The same reasoning with the numbers attached is in programmatic for mid-market brands.

What to ask before building the plan

• Which streaming publishers can I reach via deal in each country on the plan?
• What share of that market's inventory is available programmatically?
• Do the formats I want exist there?
• What currency is invoiced, and who absorbs the exchange difference?
• Who fronts platform spend while the client pays at 60 days?
• What measurement is genuinely available, and what am I assuming?

Where SeatNMD fits

SeatNMD gives agencies and advertisers access to DV360 without a direct Google contract and without the spend minimums Google asks of an agency, with access provisioned in days rather than months. You buy YouTube, CTV, DOOH, audio, display and video with Google audiences and premium inventory, and choose how it runs: Self, Support or Managed. Billing is monthly and platform costs sit on our credit lines — which is exactly the cash-flow problem that appears when operating in the region. Audiences, history and measurement stay yours.

FAQ

Can you run CTV advertising in Latin America?

Yes, programmatically through a DSP. What has to be verified before planning is which streaming publishers are reachable via deal in each country, and how much of that inventory is transacted programmatically rather than sold direct.

How much does CTV cost in Latin America?

It depends on the country, the publisher and the buying route far more than on the region. Get a quote for your specific market rather than using US benchmarks, which average a supply mix that is not yours. The cost structure is in how much CTV advertising costs.

Do I need a Google contract to buy CTV in the region?

Not necessarily with Google, but you do need contracted DSP access. An access provider gives you an advertiser account without the minimums of a direct agreement. The routes are in how to get DV360 access.

How do I measure CTV in a market without panels?

With geo holdouts, household reach and frequency from the DSP itself, movement in branded search and direct traffic in exposed areas, and publisher-level delivery. Design measurement around what exists in that market, not around what exists in the US.

Is a regional budget enough for CTV?

It is if it is concentrated. Narrow geography and audience until the reach and frequency arithmetic works, rather than spreading thin across several countries. The calculation is in DV360 minimum spend.
