Definition (canonical)
A lead is a person or company that has shown identifiable interest in your offer and left a way to contact them. Both halves matter: anonymous traffic is not a lead, and a purchased contact list shows no interest — a lead is interest PLUS reachability, sitting at the entry of the sales funnel.
The qualification ladder
Raw leads vary wildly, so operations grade them: MQL (marketing-qualified — behavior signals: downloaded the pricing guide, attended the webinar, visited pricing twice) → SQL (sales-qualified — a human confirmed fit and intent, classically via BANT-style checks: budget, authority, need, timeline) → opportunity. The ladder exists to protect the scarcest resource — salespeople's hours — from being spent on the curious. Two failure modes bracket it: gates too loose (sales drowning in students and competitors "just researching") and too tight (marketing celebrates MQL volume nobody can sell to). The fix is a WRITTEN definition of each stage agreed by both teams, revisited quarterly against closed-won data.
Scoring and speed — the two levers that pay
Scoring ranks leads by fit (industry, size, role) and behavior (recency, depth of engagement), so the best get called first; models needn't be fancy — a transparent points sheet beats an opaque black box nobody trusts. Speed-to-lead is the brutally underrated lever: contact within minutes versus hours changes reach and conversion by multiples, because interest decays and competitors answer faster. If you automate one thing in lead ops, automate the first response and the routing to a human (CRM territory).
What a lead costs and is worth
Cost per lead alone misleads — a 20 lead converting at 1% costs 2,000 per customer; an 80 lead at 8% costs 1,000. Always price leads THROUGH the funnel to cost per customer (CAC) and margin. This is also the honest lens for buying leads from vendors and marketplaces: demand transparency on source and exclusivity, test small, and measure to revenue, not to inbox volume.
FAQ
Are leads only a B2B concept? The mechanics shine in B2B and high-ticket B2C (real estate, finance, autos) — anywhere a human touch precedes purchase.
When is a lead "dead"? Later than sales feels — nurture no-timing leads with useful content; a meaningful share buys quarters later. Route them out of active pipeline, not out of the database.
Legal footnote? Consent and data-protection rules govern lead capture and outreach in most markets — a lead obtained wrong is a liability, not an asset.
