# Contextual targeting

## Context

Check [User guides documentation](https://userguides.mediarithmics.io/contextual/introduction-to-contextual-targeting) to learn more about this feature.

## Prerequisites 

URLs & hits must be captured into mediarithmics in order to perform the contextual extraction and semantic analysis. This can be done either through:

* [User event tag](/data-streams/data-ingestion/real-time-user-tracking/web-events.md) (user tracking)
* [Contextual targeting tag](/advanced-usages/contextual-targeting/general-setup.md#event-rule-configuration) (no user tracking)
* [User activities import](/data-streams/data-ingestion/bulk-processing/imports/offline-activities.md) (for mobile app only. `url` field needs to be populated in that case)

## Setup

To configure the Contextual targeting feature, follow the setup steps below depending on your needs:

1. [General setup](/advanced-usages/contextual-targeting/general-setup.md) - **MANDATORY**. This initial configuration is required for all customers using the Contextual targeting feature
2. [Activation setup](/advanced-usages/contextual-targeting/activation-setup.md) - OPTIONAL. Complete this step only if you plan to activate your contextual targeting lists. You do not need this step if your goal is solely to use contextual extraction for audience building within the platform
