Amazon DSP vs DV360 vs The Trade Desk: How buyers should think about inventory, Data, and optimization

Choosing a demand-side platform is not simply a technology decision.

The platform affects the inventory a buyer can access, the audience data available for targeting, the level of campaign control, and how media performance is measured.

Amazon DSP, Display & Video 360, and The Trade Desk are three of the most widely considered platforms for enterprise programmatic advertising. However, they are built around different strengths.

A useful way to compare them is through three areas:

• Inventory access
• Audience and identity data
• Optimization and measurement

This guide explains how each platform approaches these areas and how advertisers can choose the right DSP for their campaign objectives.

Amazon DSP vs DV360 vs The Trade Desk at a glance

The platforms can be broadly positioned as follows:

• Amazon DSP: Built around Amazon’s commerce, shopping, streaming, and first-party audience signals
• Display & Video 360: Closely integrated with Google’s advertising and measurement ecosystem, including YouTube
• The Trade Desk: Focused on independent, cross-channel media buying across the open internet

These descriptions are useful starting points, but no platform is automatically the best option for every advertiser.

The right choice depends on where the target audience spends time, what data the advertiser can activate, and how campaign success will be measured.

Comparing DSP inventory access

Inventory determines where ads can appear.

It also affects campaign reach, media quality, pricing, creative formats, and the level of control a buyer has over placements.

Amazon DSP inventory

Amazon DSP provides access to Amazon-owned properties as well as third-party publishers and exchanges.

Amazon-owned inventory can include environments such as:

• Amazon shopping properties
• Prime Video
• Fire TV
• Twitch
• IMDb
• Amazon devices and services

Amazon DSP also provides access to premium third-party websites, mobile apps, streaming television, video, and audio inventory. This means the platform is not limited to ads displayed on Amazon itself.

Where Amazon DSP is strongest

Amazon DSP is particularly valuable when an advertiser wants to connect media exposure with shopping and purchase behaviour.

Its inventory strategy works well for:

• Retail and e-commerce campaigns
• Consumer packaged goods
• Product launches
• Connected TV campaigns supported by commerce data
• Customer acquisition and remarketing
• New-to-brand measurement

What buyers should consider

Amazon DSP’s strongest differentiation is not simply its media inventory.

It is the ability to combine that inventory with Amazon’s first-party shopping, browsing, streaming, and purchase signals.

Advertisers whose products are not sold on Amazon may still use the platform, but the strategic value depends on whether Amazon’s audiences and measurement capabilities support the campaign objective.

Display & Video 360 inventory

Display & Video 360, commonly known as DV360, provides access to display, video, connected TV, audio, native, mobile app, and digital out-of-home inventory.

A major advantage is its ability to buy YouTube inventory through YouTube and partners line items.

DV360 also supports inventory from exchanges, publishers, private marketplace deals, and programmatic guaranteed agreements.

Where DV360 is strongest

DV360 is often considered when campaigns rely heavily on:

• YouTube
• Online video
• Connected TV
• Google advertising products
• Campaign Manager 360
• Floodlight conversion tracking
• Cross-channel campaign management

The platform can be particularly useful for advertisers that already use Google’s marketing and measurement tools.

What buyers should consider

YouTube inventory is an important reason many advertisers include DV360 in their media strategy.

However, buyers should not assume that every targeting, creative, and measurement option available for standard DV360 inventory works in the same way for YouTube.

YouTube and partners line items have their own targeting, creative, and measurement requirements.

The Trade Desk inventory

The Trade Desk is positioned as an independent demand-side platform for buying media across the open internet.

It supports channels such as:

• Display
• Online video
• Connected TV
• Audio
• Native
• Mobile
• Digital out-of-home

The platform works with publishers, broadcasters, streaming services, and media owners across these channels.

Where The Trade Desk is strongest

The Trade Desk is often considered for campaigns that require:

• Cross-channel reach
• Connected TV buying
• Audio and digital out-of-home activation
• Flexible supply-path decisions
• Third-party data integrations
• Detailed control over inventory and bidding
• Independent open-internet media buying

What buyers should consider

Unlike Amazon and Google, The Trade Desk does not depend on a large consumer marketplace or search-and-video ecosystem of its own.

Its value comes from connecting advertisers to external publishers, media owners, data providers, and measurement partners.

This can offer greater flexibility, but it may also require stronger programmatic expertise from the buying team.

Comparing audience data and identity

Inventory determines where an ad can appear.

Data determines who the advertiser tries to reach and how those audiences are evaluated.

Amazon DSP data

Amazon DSP can use signals generated across Amazon’s shopping, browsing, streaming, and purchasing environments.

These signals can help advertisers build audiences based on activities such as:

• Product research
• Category interest
• Past purchases
• Brand interactions
• Streaming behaviour
• Shopping patterns

Amazon describes its platform as using browsing, streaming, and purchasing signals from across Amazon properties to support campaign delivery and optimization.

Key advantage

The main advantage is the connection between advertising and commerce behaviour.

An advertiser can move beyond inferred interest and use signals related to what customers browse and buy.

This makes Amazon DSP useful for campaigns focused on:

• Product consideration
• Purchase intent
• Customer acquisition
• Repeat purchases
• New-to-brand growth
• Retail sales measurement

Limitation to consider

Amazon’s data is most valuable when its commerce signals are relevant to the advertiser’s category and customer journey.

It should not automatically be treated as a complete replacement for an advertiser’s own first-party customer data.

DV360 data

DV360 supports Google audience segments, advertiser first-party data, contextual targeting, custom audiences, and campaign measurement through products such as Floodlight.

Depending on account access, campaign type, market, and privacy requirements, buyers may use:

• Affinity audiences
• In-market audiences
• Custom segments
• Customer data
• Website visitor data
• Contextual and content targeting
• Geographic and device signals

Key advantage

DV360’s main data advantage is its integration with Google’s broader advertising and measurement environment.

For organizations already using Campaign Manager 360, Floodlight, Google Analytics, or YouTube, this can simplify activation and reporting.

Limitation to consider

Google has continued to change how targeting and inventory controls work across DV360.

For example, some settings have been consolidated at the partner and line-item levels rather than the insertion-order level. Buyers should therefore confirm current platform documentation before designing campaign structures or automation workflows.

The Trade Desk data

The Trade Desk supports first-party data, third-party data, retailer data, publisher data, and identity integrations.

It also supports Unified ID 2.0, an open-source identity framework intended to support targeting and measurement in a more privacy-conscious advertising environment.

Key advantage

The main strength is flexibility.

Advertisers can combine:

• Customer relationship management data
• Data clean-room outputs
• Retail media data
• Publisher first-party data
• Third-party audience segments
• Identity solutions
• Measurement partner data

This can be valuable for advertisers that want to control their data strategy instead of relying mainly on one platform’s owned consumer ecosystem.

Limitation to consider

A flexible data environment can also require more planning.

Advertisers need clear governance around:

• Consent
• Identity resolution
• Audience onboarding
• Data quality
• Measurement methodology
• Regional privacy requirements

The technology alone does not guarantee a strong data strategy.

Comparing bidding and optimization

A DSP does more than place bids.

It evaluates users, placements, devices, publishers, audiences, creative assets, and conversion signals to decide when and how much to bid.

Amazon DSP optimization

Amazon DSP is designed to optimize campaigns using Amazon’s first-party signals and the advertiser’s selected campaign goal.

Optimization may focus on outcomes such as:

• Reach
• Detail-page views
• Purchases
• Return on ad spend
• New-to-brand sales
• Video completion
• Brand awareness

Where Amazon DSP performs well

Amazon DSP is especially relevant when the campaign objective can be connected to product discovery or purchase behaviour.

This makes it useful for lower-funnel and full-funnel retail media strategies.

Buyer consideration

Advertisers should look beyond total attributed sales.

Important questions include:

• Were the customers new to the brand?
• Did the ads create incremental purchases?
• Which products were purchased after exposure?
• Was the platform capturing demand or creating demand?
• How much conversion activity would have happened without advertising?

DV360 optimization

DV360 provides automated bidding strategies that optimize toward goals such as:

• Conversions
• Revenue
• Cost per acquisition
• Viewable impressions
• Video completion
• Reach
• Custom bidding objectives

Its close connection with YouTube and Google measurement products can make it useful for full-funnel campaign optimization.

Where DV360 performs well

DV360 is a strong option when advertisers want to connect:

• YouTube reach
• Display and video activity
• Floodlight conversions
• Campaign Manager 360 reporting
• Brand and performance objectives

Buyer consideration

Optimization quality depends heavily on conversion setup.

Before relying on automated bidding, teams should verify:

• Floodlight configuration
• Conversion priority
• Attribution windows
• Event quality
• Data volume
• Campaign learning periods

Automated bidding cannot correct inaccurate conversion data.

The Trade Desk optimization

The Trade Desk uses its Koa artificial intelligence engine and Kokai platform to support bidding, audience selection, inventory decisions, and cross-channel optimization.

Koa can prioritize inventory based on campaign goals and help determine an appropriate price for an impression.

The platform has also introduced omnichannel optimization features designed to evaluate performance across the broader media mix rather than optimizing every channel in isolation.

Where The Trade Desk performs well

The Trade Desk is often preferred by teams that want:

• Granular campaign controls
• Cross-channel frequency management
• Supply-path visibility
• Flexible data activation
• Custom optimization strategies
• Open-internet campaign management

Buyer consideration

The platform can provide significant control, but buyers need the expertise to use it effectively.

More controls do not automatically lead to better performance.

The campaign team still needs to make informed decisions about:

• Bidding
• Frequency
• supply paths
• Audience quality
• Inventory quality
• Creative rotation
• Measurement

Amazon DSP vs DV360 vs The Trade Desk comparison

How buyers should choose a DSP

The better question is not, “Which DSP is the best?”

The better question is, “Which DSP gives this campaign the right combination of inventory, data, control, and measurement?”

Choose Amazon DSP when commerce signals are central

Amazon DSP may be the right fit when:

• The advertiser sells physical products
• Amazon shopping signals are relevant
• The campaign is focused on purchases or product consideration
• Retail attribution is important
• The team wants to reach audiences across Amazon-owned and third-party inventory
• New-to-brand reporting is part of the measurement strategy

It can support both endemic advertisers that sell on Amazon and non-endemic advertisers whose audiences are represented in Amazon’s data.

Choose DV360 when YouTube and Google integration matter

DV360 may be the right fit when:

• YouTube is a major part of the media plan
• The advertiser uses Campaign Manager 360 or Floodlight
• Video reach and completion are important
• The campaign combines brand and performance goals
• The team wants to manage multiple inventory types within Google’s enterprise ad technology stack

DV360 is often strongest when its campaign and measurement tools are used as part of a broader Google-based workflow.

Choose The Trade Desk when flexibility and omnichannel control matter

The Trade Desk may be the right fit when:

• The campaign runs across CTV, audio, display, video, native, or digital out-of-home
• The advertiser wants to activate custom data partnerships
• Supply-path transparency matters
• Cross-channel frequency control is a priority
• The buying team wants granular campaign controls
• The advertiser is building an open-internet media strategy

It is especially relevant for advanced programmatic teams managing complex, cross-channel campaigns.

When a multi-DSP strategy makes sense

Large advertisers do not always need to choose only one platform.

A multi-DSP strategy can make sense when each DSP has a specific role.

For example:

• Amazon DSP may support commerce audiences and retail measurement
• DV360 may support YouTube and Google-connected video buying
• The Trade Desk may support independent CTV and omnichannel open-internet activation

However, using several DSPs also creates operational challenges.

These can include:

• Duplicate audience reach
• Inconsistent frequency controls
• Competing bids
• Different attribution methodologies
• Fragmented reporting
• Higher platform and staffing costs

A multi-DSP strategy should therefore be based on a clear inventory or data advantage, not simply the desire to use more platforms.

Questions to ask before selecting a DSP

Before choosing a platform, buyers should ask:

What inventory is genuinely unique or strategically important?

Identify the publishers, platforms, channels, and formats that the campaign needs.

Which audience data creates a real advantage?

Determine whether the strategy depends on commerce data, Google audiences, advertiser first-party data, publisher data, or independent identity solutions.

How will success be measured?

Confirm whether the campaign will be evaluated using sales, conversions, reach, brand lift, incrementality, or another business outcome.

How much control does the team need?

Some teams prefer automated workflows. Others need detailed bidding, supply, and frequency controls.

Does the team have the right expertise?

A more advanced platform may require experienced traders, analysts, engineers, and measurement specialists.

How will duplication be managed across platforms?

Advertisers using multiple DSPs need a clear approach to audience overlap, frequency, attribution, and reporting.

Common mistakes when comparing DSPs

Comparing feature lists without considering strategy

A long feature list does not show whether a platform is suitable for a specific business objective.

Assuming owned inventory means limited reach

Amazon DSP and DV360 can access inventory beyond their owned properties, while their owned ecosystems remain important strategic advantages.

Assuming independence automatically means transparency

An independent DSP can provide more flexibility, but transparency still depends on reporting configuration, supply-path choices, and commercial agreements.

Choosing a platform before defining measurement

The measurement framework should influence the DSP decision, not be added after activation.

Using multiple DSPs without clear roles

Every platform should have a defined purpose. Otherwise, the advertiser may create duplication rather than incremental reach.

Final takeaway

Amazon DSP, DV360, and The Trade Desk are not interchangeable platforms.

Each is built around a different strategic advantage:

• Amazon DSP connects programmatic media with commerce and purchase signals
• DV360 connects enterprise media buying with YouTube and Google’s advertising ecosystem
• The Trade Desk provides flexible, cross-channel access across the open internet

The best platform depends on the campaign objective.

Buyers should evaluate which DSP offers the strongest combination of inventory, audience data, optimization, measurement, and operational control for the specific task.

For some advertisers, that means selecting one primary DSP.

For others, it means building a coordinated multi-DSP strategy in which every platform has a clearly defined role.

The competitive advantage does not come from using the most platforms.

It comes from using the right platform for the right purpose.
