# Signal structure

Each signal in InGrow is a rich data object that contains detailed information about the engagement and the person who initiated it. Understanding the structure of a signal will help you better interpret the data and identify key prospects.

A signal is composed of the following main components:

### Signal Profile

This section contains information about the LinkedIn user who generated the signal. It includes:

* **Full Name:** The full name of the user.
* **Headline:** The user's professional headline from their LinkedIn profile.
* **Profile Picture URL:** A link to their profile picture.
* **Username and URN:** Unique identifiers for the user's LinkedIn profile.
* **Company Information:** The name of the company where the user is currently employed, if available.

### Signal Score

This is a numerical value that represents the intensity of the user's engagement. The score is calculated based on the type, frequency, and recency of their interactions. A higher score indicates a more engaged and potentially higher-intent prospect.

### Activity Details

This section provides specifics about the engagement itself:

* **Latest Activity Type:** The type of the most recent interaction (e.g., "comment," "interaction," "connection").
* **Latest Activity Date:** The timestamp of the most recent interaction.
* **Interactions:** A list of all reactions (likes, loves, etc.) the user has had with the tracked profile's content.
* **Comments:** The full text of any comments the user has made.
* **Connection and Profile View Data:** Information about connection requests and profile views, if applicable (requires LinkedIn Premium).
