A Visitor Profile is a unified, real-time representation of a user. It stores attributes such as demographics, behavior, engagement history, and enrichment data, continuously updating as new events are received.
Visitor attributes are data points stored within a visitor profile. They can be:
Badges are boolean attributes that represent whether a visitor meets certain conditions. They are commonly used to flag behaviors such as "High-Value Customer" or "Cart Abandoner".
A Tally attribute counts how many times an event or condition occurs. For example, tracking the number of purchases or page views over time.
Sets store unique values without duplication, such as product IDs viewed or campaign names interacted with by a visitor.
Enrichments are rules that define how visitor attributes are updated. They process incoming event data to create meaningful customer insights.
Audiences are groups of visitors who meet specific criteria based on attributes and behaviors. These audiences can be shared with marketing and analytics tools for personalization and targeting.
Visitor-level data persists across sessions, while visit-level data applies only to a single session. AudienceStream primarily focuses on visitor-level data for long-term profiling.
Connectors allow AudienceStream to send data to external systems such as:
Event-based connectors send data immediately when an event occurs, while profile-based connectors trigger when visitor profile attributes change.
The data layer is a structured set of variables capturing user interactions. It ensures consistent data collection and feeds clean, reliable data into AudienceStream.
The Trace tool helps debug visitor data in real time by showing how events, attributes, and audiences are processed within AudienceStream.
AudienceStream supports consent flags and privacy controls to ensure compliance with regulations like GDPR and CCPA by controlling data collection and activation.
Identity resolution merges multiple identifiers (cookie ID, email, CRM ID) into a single visitor profile, enabling cross-device and cross-channel tracking.
Lookup tables enrich visitor data by mapping values, such as converting postal codes into city or region names.
APIs enable data ingestion, profile lookup, and real-time activation, allowing integration with backend systems and custom applications.
Real-time segmentation updates audiences instantly based on live user behavior, allowing immediate personalization and activation.
Visitor stitching connects multiple sessions and devices into one profile using identifiers, ensuring a unified customer view.
A CDP focuses on first-party, persistent customer profiles, while a DMP primarily manages third-party anonymous data for advertising.
It integrates data from web, mobile, CRM, offline, and IoT sources to deliver consistent experiences across all customer touchpoints.
AudienceStream empowers marketers to move from siloed data to actionable insights, enabling real-time, personalized, and privacy-compliant customer engagement.
