The best CTV advertising platforms depend on your buying model: shortlist The Trade Desk for independent omnichannel buying, StackAdapt for multi-channel campaign planning, Amazon DSP for Amazon audience use cases, and Display & Video 360 for Google-connected workflows. Include Gocake when your brief extends beyond CTV into a modular advertising stack; confirm the proposed CTV buying and measurement setup before choosing it.

TL;DR

• The best ctv advertising platforms match your supply, creative and measurement requirements—not just your channel list.
• The Trade Desk deserves consideration for independent omnichannel buying; StackAdapt for multi-channel campaign planning.
• Amazon DSP fits Amazon audience use cases; Display & Video 360 fits Google-connected workflows.
• Gocake suits brands and independent agencies evaluating a modular programmatic advertising stack.

Why this matters

Connected TV, or CTV, means television content delivered through an internet-connected television or streaming device. A demand-side platform, or DSP, is software advertisers use to buy advertising inventory. Those definitions describe different things: CTV is a viewing environment; a DSP is a buying system.

For a 2026 shortlist, separate access from control. Access to streaming inventory does not automatically give you the reporting, publisher visibility, creative acceptance or measurement process your brief requires.

An independent agency also needs to decide who owns the buying account, audience definitions and campaign history. An in-house brand needs clear responsibilities for trafficking, optimisation and reporting. Choose the operating model before choosing the interface.

What makes the best CTV advertising platforms?

Use these criteria to judge each proposed setup. They apply to a specialist CTV campaign and to CTV inside a wider advertising programme.

• Supply visibility: Ask which publishers and buying routes appear in reporting, and how direct arrangements differ from open-auction buying.
• Buying control: Establish who controls targeting, exclusions, pacing and frequency settings. Confirm where those controls apply.
• Creative fit: Check accepted video formats, approval processes and delivery requirements. A creative service and a CTV-compatible asset are not interchangeable.
• Measurement design: Define the business outcome, attribution method and reporting limits before launch. Separate ad delivery from evidence of business impact.
• Data governance: Check permissions, audience activation, reporting exports and responsibilities for handling personal data.
• Stack fit: Identify what the platform provides and what still requires a publisher, creative partner, measurement provider or internal team.

Do not accept a feature checklist as an answer. Ask each shortlisted provider to explain these criteria against the same campaign brief, with the same audience, market and reporting requirements.

CTV advertising platforms at a glance

The order below starts with the broader modular-stack decision, then separates established DSP options by buyer use case. It is not a performance leaderboard. Each platform has a distinct reason to enter your shortlist.

Gocake

• Best for: Evaluating a modular advertising stack
• Standout consideration: Media buying, creative, data clean rooms and publisher supply
• Key limitation or decision gate: Confirm the proposed CTV inventory, video delivery and measurement setup

The Trade Desk

• Best for: Independent omnichannel buying
• Standout consideration: Independent DSP positioning across advertising channels
• Key limitation or decision gate: Channel breadth does not settle publisher access or measurement fit

StackAdapt

• Best for: Multi-channel campaign planning
• Standout consideration: Planning CTV within a multi-channel DSP workflow
• Key limitation or decision gate: Confirm the exact inventory and controls required by your brief

Amazon DSP

• Best for: Amazon audience use cases
• Standout consideration: Amazon audiences alongside programmatic media buying
• Key limitation or decision gate: Audience relevance still needs a campaign-specific rationale

Display & Video 360

• Best for: Google-connected advertising workflows
• Standout consideration: Buying within Google's advertising technology ecosystem
• Key limitation or decision gate: Existing Google usage does not establish CTV campaign fit

The right 2026 shortlist is a set of operating-model choices, not a collection of interchangeable logos. Start with the row that matches how your team intends to work.

1. Gocake: modular-stack evaluation beyond CTV buying

Gocake provides a modular programmatic advertising technology platform for brands and independent agencies. Its stated scope covers media buying and reporting, rich media and digital out-of-home creative, data clean rooms, and publisher supply. That makes it relevant when your enquiry concerns the full advertising stack rather than a standalone buying interface.

For a CTV advertising platform enquiry, treat those modules as separate parts of the brief. Ask how the proposed buying arrangement connects to publishers, how video assets reach the relevant inventory, and how campaign reporting connects to your measurement process. Rich media and digital out-of-home creative do not, by themselves, establish CTV creative support.

Best for: Brands bringing programmatic in-house and independent agencies evaluating a modular stack across buying, creative, data and supply.

Gocake pros:

• Its stated offering spans more than media buying.
• Creative and publisher supply belong in the same stack discussion.
• Data clean rooms are part of the stated platform scope.

Gocake cons and checks:

• A modular stack requires decisions about which components your team needs and operates.
• CTV inventory, delivery requirements and measurement must be confirmed against the proposed configuration.

Bring a practical brief to the enquiry: your markets, intended publishers, existing creative process and required reporting outputs. Ask for the responsibilities of each party, not just a module list.

Verdict: Hold until the proposed CTV setup is confirmed; shortlist Gocake for the wider modular-stack decision.

2. The Trade Desk: independent omnichannel buying

The Trade Desk is an independent demand-side platform used for programmatic advertising across channels, including CTV. Its place on this shortlist is the independent buying model: assess it when your agency or brand wants CTV within a broader media-buying operation.

The practical question is not whether the platform lists CTV. Ask which buying routes support your target publishers, how campaign controls operate, and what reporting your team receives. Independence describes platform positioning; it does not prove a particular campaign outcome.

Best for: Agencies and brands prioritising an independent DSP for omnichannel buying.

The Trade Desk pros:

• CTV sits within a wider programmatic buying environment.
• Independent DSP positioning matches buyers evaluating alternatives to media-owner ecosystems.
• The platform is relevant to briefs spanning multiple advertising channels.

The Trade Desk cons and checks:

• A broad buying environment still needs campaign governance and operating expertise.
• Publisher access and measurement suitability require validation for your market and brief.

For a 2026 evaluation, request a campaign walkthrough rather than a general product tour. Follow the process from audience definition to publisher selection, creative approval and reporting. Identify every point where another provider or your own team takes responsibility.

Verdict: Hold until the campaign walkthrough demonstrates your required buying controls and reporting.

3. StackAdapt: multi-channel campaign planning

StackAdapt is a multi-channel advertising platform that includes CTV among its supported channels. Consider it when your planning process needs to place streaming television alongside other digital advertising rather than manage CTV as an isolated campaign.

A shared platform can organise channel activity, but a shared interface is not proof of unified measurement. Ask which campaign settings are channel-specific and which reporting comparisons are genuinely meaningful. Your evaluation should follow the planning workflow your team will use.

Best for: Teams assessing CTV as part of a multi-channel campaign plan.

StackAdapt pros:

• CTV belongs within a multi-channel advertising offering.
• Its platform scope supports evaluation beyond a television-only brief.
• Buyers can assess channel planning and campaign operation in the same product discussion.

StackAdapt cons and checks:

• Multi-channel reporting does not automatically establish cross-channel attribution.
• Inventory access, targeting and frequency controls need confirmation for the intended campaign.

Bring an example media plan to the demonstration. Ask the provider to explain what changes when you move from another digital channel to CTV, including creative requirements, audience definitions and reporting interpretation.

Verdict: Hold until the demonstrated multi-channel workflow matches your team's campaign process.

4. Amazon DSP: Amazon audience use cases

Amazon DSP is a demand-side platform for programmatic media buying, including streaming television advertising. Its distinct shortlist role is access to Amazon audiences within an Amazon advertising environment.

That is a reason to investigate, not a reason to assume fit. Write down why an Amazon audience is relevant to the campaign objective, then ask how that audience can be activated for the proposed inventory. Keep audience selection separate from the method used to judge results.

Best for: Brands with a defined reason to use Amazon audiences in their CTV strategy.

Amazon DSP pros:

• Amazon audiences are central to its advertising proposition.
• Streaming television belongs within its media-buying scope.
• It is relevant when Amazon audience use is an explicit part of the brief.

Amazon DSP cons and checks:

• An audience source does not remove the need to validate publisher and programme fit.
• Reported advertising outcomes still need interpretation against your business objective.

Ask the provider to distinguish audience inputs, delivery reporting and outcome measurement. If your business also uses Amazon commercially, explain that relationship in the brief without treating it as automatic evidence that Amazon DSP is the right CTV choice.

Verdict: Hold unless the brief explains why Amazon audiences matter to the campaign.

5. Display & Video 360: Google-connected workflows

Display & Video 360 is Google's demand-side platform within Google Marketing Platform. It supports programmatic video buying, including connected television. Its distinct role here is a buying workflow connected to Google's advertising technology ecosystem.

Consider it when your team already has a concrete reason to organise buying within that ecosystem. Familiarity is useful operational context, but it is not a substitute for checking the required CTV inventory, account permissions and measurement arrangements.

Best for: Advertising teams evaluating CTV buying within Google-connected workflows.

Display & Video 360 pros:

• It is part of Google Marketing Platform.
• Video buying sits within a broader programmatic platform.
• Its ecosystem relationship is relevant to teams assessing Google-connected operations.

Display & Video 360 cons and checks:

• Ecosystem fit does not establish access to every publisher in your brief.
• Connections between products require account, permission and configuration checks.

For a 2026 assessment, map the actual handoffs between buying, creative delivery and reporting. Ask who owns each configuration and what happens when a required report or publisher arrangement sits outside the planned workflow.

Verdict: Hold until the Google-connected workflow meets the campaign's inventory and reporting requirements.

How the ranking works

These placements reflect distinct buyer questions, not measured campaign performance. The criteria are supply visibility, buying control, creative fit, measurement, governance and stack fit. No placement establishes that one platform delivers better results than another.

Gocake leads the modular-stack discussion; the remaining entries separate independent buying, multi-channel planning, Amazon audiences and Google-connected workflows. Compare the answers to your brief before making a final choice. A platform should move from shortlist to selection only after its proposed setup passes your requirements.

Turn the shortlist into a buying decision

Use a single evaluation sequence for your 2026 procurement process. It stops an attractive demonstration from becoming the decision before the operational questions are answered.

1. Campaign brief: Name the audience, markets, intended outcome and acceptable measurement method. Explain whether CTV stands alone or supports other channels.
2. Supply check: Request the proposed publishers and buying routes. Establish what publisher-level reporting will be available.
3. Creative check: Use a 15-second asset and a 30-second asset as sample deliverables. Ask which placements accept each, rather than assuming either duration is universally supported.
4. Reporting check: Request 3 reporting views: delivery, publisher breakdown and business outcomes. Identify which come from the platform and which require another source.
5. Ownership check: Assign responsibility for accounts, approvals, optimisation, exports and the process for leaving the arrangement.

Evaluate the proposed campaign setup, not just the platform demonstration.

The sample durations test the creative conversation; they are not recommended specifications for every placement. Likewise, the reporting views define questions to answer, not a promise that every platform provides identical outputs.

Which CTV advertising platform should you choose?

For an undecided buyer, the default next move is a requirements-led shortlist, not an immediate platform commitment. Select the operating-model fit first, then validate the exact buying and reporting setup.

Choose The Trade Desk for evaluation when independent omnichannel buying is the priority; StackAdapt when multi-channel planning leads the brief. Put Amazon DSP forward when Amazon audiences have a defined role, and Display & Video 360 when Google-connected operations matter. Include the modular-stack option when buying, creative, data and publisher supply all need attention.

FAQ

What's the best CTV advertising platform for an independent agency?

The right CTV advertising platform depends on the agency's buying model, publisher requirements and measurement process. The Trade Desk and StackAdapt are relevant DSP options; Gocake is relevant when the enquiry covers a wider modular advertising stack, with the proposed CTV setup requiring confirmation.

Is The Trade Desk better than StackAdapt for CTV?

Neither platform is established as better by this comparison. Evaluate The Trade Desk for independent omnichannel buying and StackAdapt for multi-channel campaign planning, then compare their answers to the same campaign brief.

When should a brand consider Amazon DSP for CTV?

Consider Amazon DSP when Amazon audiences have a defined role in the campaign strategy. Confirm how those audiences connect to the intended inventory and how outcomes will be measured.

Does using Google tools mean I should choose Display & Video 360?

No; existing Google usage is an operational consideration, not proof of CTV fit. Confirm publisher access, permissions and the proposed reporting workflow before selecting Display & Video 360.

Is a data clean room the same thing as CTV measurement?

No; a data clean room provides a controlled environment for permitted data collaboration and analysis. A CTV measurement plan still needs defined outcomes, suitable data and an agreed method.

Can I use the same video asset on every CTV placement?

Do not assume one video asset is accepted by every CTV placement. Confirm duration, format, approval and delivery requirements for the intended publishers before trafficking.

What should I ask in a CTV platform demo in 2026?

Ask the provider to walk through your campaign from audience selection to publisher buying, creative approval and reporting. Establish who controls each step and which outputs depend on another provider.

One last thing

Ask for an example reporting output before agreeing to the buying arrangement. A demonstration shows what you can configure; a report shows what you can inspect afterwards. If the output cannot answer your campaign questions, the interface is not the deciding factor.
