# Signals
Signals are explicit indicators of relevance or buying intent,\
They also feed segmentation, scoring, and automation.
SalesMonk supports:
* Built-in signals (traffic, hiring, funding, etc.)
* Custom AI signals generated from public web data
Signals can be:
* Boolean (true/false)
* Numeric (counts, scores)
* Textual (research-based)
\
How These Concepts Connect at a system level:
* Accounts contain Leads
* Leads and Accounts generate Activities
* Signals enrich Accounts
* Segments group Leads or Accounts
* Plays act on Segments
* Campaigns execute outreach
* Meetings close the GTM loop
This shared model allows inbound and outbound to function as one system.
