Lead
A person or organization that has shown identifiable interest and may have a relevant business need.
Also called: leads, sales lead, sales leads
Definition
A lead may begin as a call, form submission, booking, referral, message, or other identifiable inquiry. Its value depends on relevance, intent, fit, timing, and whether the business can respond effectively.
Why it matters
Clear lead definitions keep marketing reports connected to real opportunities rather than treating every interaction as equal.
Common misunderstanding
Traffic, impressions, clicks, and anonymous website events are not automatically leads.
