A lead source is where a lead comes from (a database, a referral, an event). A channel is how you reach or attract them (email, SEO, ads). Knowing both helps you invest in what works.

- LinkedIn and professional networks
- Maps and local directories
- Industry associations and directories
- Events and trade show lists
- Website visitors and inbound forms

Frequently asked questions
What are the best B2B lead sources?
Referrals and partners usually produce the best leads; databases, LinkedIn and maps produce the most scalable ones. Most teams combine both.
What is the difference between a lead source and a channel?
The source is where the lead came from (e.g. a database or event); the channel is how you contacted or attracted them (e.g. email or SEO).
