Lead Scoring vs Lead Grading: What's the Difference?

Lead scoring measures a lead's engagement and behaviour with your brand quantitatively - points added for email opens, clicks, page visits, or a demo request, usually accumulating (and often decaying) over time. It answers the question: how active and interested is this lead right now?

Lead grading measures fit against your ideal customer profile - firmographic and demographic attributes like company size, industry, job title, and budget authority - typically expressed as a letter grade from A to F. It answers a different question entirely: is this the right kind of lead at all?

The two need to be read together, not separately. A high-score, low-grade lead - an intern at a five-person company who's opened every email - is not a good lead despite the activity. A high-grade, low-score lead - a perfect-fit VP who hasn't engaged much yet - deserves continued nurturing, not disqualification. Combining score and grade into a single matrix, rather than relying on either number alone, is what actually predicts whether a lead is ready for sales.
