Lead Generation
The practice of converting interest into contactable records, like form fills, tool signups, and demo requests, that sales or nurture can follow up with.
Lead generation is often used as a synonym for demand generation, and the confusion is expensive. Lead gen is one stage inside the larger discipline: the capture stage, where anonymous attention becomes a reachable audience. Demand gen also creates the interest in the first place and nurtures it afterward; lead gen is the moment of exchange in the middle.
The classic failure mode is buying volume. Gate enough content and you will hit any lead target while sales complains that every record is junk, because a form fill says nothing about fit or intent. The fix is to measure capture quality one stage downstream: the lead-to-MQL rate tells you whether what you captured was demand or just contact data.
The strongest capture mechanisms give value before they ask: calculators, audits, templates, and tools that high-intent buyers seek out on their own. The demand gen vs lead gen guide unpacks the relationship in full.
