Understand ad:personam Data Marketplace targeting options: audience, contextual, and IAB cookieless segments. Compare providers, CPMs, and best uses.
The Data Marketplace in ad:personam gives you three complementary ways to improve targeting precision: cookie-based audiences, contextual segments, and cookieless IAB household segments. Each option serves a different planning objective, budget profile, and privacy requirement.
This guide summarises how these segment types work, when to use each one, and how to combine them for stronger campaign outcomes.
What Is the Data Marketplace?
The Data Marketplace is where you select third-party targeting segments and apply them to your campaigns. Segment costs are added to your media CPM and affect your effective bid and forecast outcomes.
You can apply these segments across Display, Video, CTV, and In-App campaigns.
1) Audience Targeting
Audience targeting uses cookie-based behavioural and demographic profiles to reach users likely to engage or convert. It is ideal when you need granular persona precision, in-market intent, or B2B segment logic.
Coverage
Audience segments are available across EMEA, APAC, LATAM, and MENA regions.
Strengths
- Detailed demographic and behavioural segmentation
- Strong prospecting and conversion support
- Large category catalogue for advanced persona design
Watchouts
- Cookie dependency can reduce match rates in Safari, Firefox, and some app environments
- Segment fees should be monitored to preserve efficient CPM

2) Contextual Targeting
Contextual targeting matches ads to page topics instead of user profiles. It is a strong privacy-first approach and works well for upper-funnel reach, brand alignment, and cookieless execution.
Coverage
Contextual segments are available across EMEA, APAC, and US inventories.
Strengths
- No cookie dependency
- Strong message-to-content relevance
- Useful for prospecting and privacy-safe scale
Watchouts
- Context signals reflect page intent, not user identity
- Topic selection should align tightly with campaign objective

3) IAB Audience Targeting
IAB Audience targeting provides cookieless, household-level segments based on deterministic IP signals and privacy-safe modelling. It is particularly effective for CTV and In-App inventory, where cookie-based data is limited.
Coverage
IAB segments are available across EMEA, APAC, MENA, and US regions.
Strengths
- Built for cookie-restricted environments
- Strong privacy compliance profile
- Cost-efficient audience layer for broad activation
Watchouts
- Household-level logic may be less granular than individual cookie profiles
- Country availability differs by segment package

How to Choose the Right Segment Strategy
Use this practical decision framework:
- Need user-level precision and behavioural depth: start with Audience Targeting.
- Need privacy-first reach at scale: start with Contextual or IAB.
- Running CTV/In-App campaigns: prioritise IAB and Contextual.
- Need balanced performance and resilience: combine Audience + Contextual or IAB + Contextual.
Budget and Forecast Considerations
Segment fees directly influence your total CPM and may reduce effective bid competitiveness if stacked aggressively.
Before launch:
- Validate segment costs in your setup.
- Run Forecast with your intended targeting mix.
- Adjust CPM or simplify segment combinations if win rate drops below target.
Recommended Workflow
- Define goal: awareness, traffic, leads, or conversion.
- Select initial segment family (Audience, Contextual, or IAB).
- Add only high-intent categories first.
- Forecast expected delivery and win rate.
- Launch, monitor, and iterate segment mix by performance.
