## Tracked Signal Types

InGrow captures the following types of signals:

* **Reactions:** All forms of reactions to posts, including Likes, Loves, Celebrates, Supports, Insightful, and Funny.
* **Comments:** The full text of comments made on posts, providing context to the engagement.
* **Connections:** New connection requests and acceptances related to the tracked profile.
* **Profile Views:** Notifications of who has viewed the tracked profile.

By tracking these signals, InGrow provides a comprehensive view of the audience's interaction with the tracked profiles, helping you identify the most engaged prospects.
