What is segmentation in AEP?
Segmentation defines rules over profile attributes and events to create audiences. The Segmentation Service evaluates them and makes the resulting audiences available for activation and for Adobe applications.

What are the segmentation types in AEP?
Batch evaluates all profiles on a schedule, streaming evaluates qualifying rules continuously as data arrives, and edge evaluates rules at the Edge for same-page personalisation. Each has its own eligibility rules and latency.

Which segmentation type applies to a customer whose balance rises above 10,000 in real time?
Streaming segmentation, provided the rule is streaming-eligible and the balance attribute arrives through a streaming path. Batch would only qualify after the next scheduled run.

How do I segment customers with more than three purchases in seven days?
Build an audience in Segment Builder using a purchase event count with a rolling seven-day time constraint. Check whether the rule is streaming-eligible or will run in batch.

What is PQL?
Profile Query Language (PQL) is the language behind audience rules. Segment Builder generates it, and the Segmentation API accepts it for programmatic audience creation.

What is edge segmentation?
Edge segmentation evaluates simple audience rules on the Edge Network so a visitor can be qualified and personalised within the same interaction, using recently collected data.

What is audience composition?
Audience composition lets marketers combine existing audiences with set operations and filters, and optionally bring in data from other sources, in a visual canvas.

What is federated audience composition?
Federated audience composition builds audiences directly on data in your own warehouse and brings the results into Experience Platform without copying the full dataset first. Availability depends on your licence.
What is a lookalike audience?
A lookalike audience finds profiles similar to a seed audience using Adobe's modelling. It is a product capability, so check current availability and licence in the documentation.
Why does an audience have fewer profiles than expected?
Common causes: dataset not Profile-enabled, missing identities, the rule uses an attribute that is not populated, a time window that excludes the events, consent or merge policy filtering, or the batch run has not completed.

Why did batch segmentation finish but streaming did not qualify the profile?
The rule may not be streaming-eligible, the event may not have been processed yet, or the profile may qualify only under a different merge policy. Check eligibility and processing status.
What is a merge policy's role in segmentation?
Audiences are evaluated against the profile as merged by a chosen merge policy, so the same rule can return different members under different policies.

How do I analyse overlap between audiences?
Use the audience overlap tools in Segment Builder or audience insights, or query profile exports with Query Service when you need custom analysis.

How do I group offers or audiences for a festive campaign?
Audiences are built from rules, so name and tag the campaign audiences consistently. For offers, group them in Offer collections in Journey Optimizer decisioning.

What is the difference between an audience and a segment?
In current Adobe terminology, audience is the broader term used across products. Segment usually refers to a rule-defined audience built in Segment Builder.
