Marketing Qualified Lead: Agreeing the Definition

Most explanations of the marketing qualified lead cover what it is and which actions signal intent. This one is about the harder part: who agrees on the definition, what happens when they disagree, and how the bar goes stale. The MQL bar is a handshake between two roles. On one side, marketing, who wants leads counted and passed on. On the other, whoever closes: a sales rep, a course creator answering waitlist emails, a store owner replying to a high-ticket enquiry, a consultant taking a booking. Marketing sets a threshold, the closer works the leads, and the two must agree the threshold marks people worth a real conversation. When they disagree, it shows up fast. The closer says the leads are junk and stops working them. Marketing says the closer is lazy and hoards good leads. Both are usually half right: the bar is set to a number that flatters marketing's report, not one that matches who actually buys. The fix is not a meeting about attitude. It is a shared definition of the qualifying action, written down, that both sides accept before any lead is passed. The quieter failure is drift. A definition set once and never revisited stops predicting revenue. Buyer behaviour changes, a channel starts sending different traffic, a new offer pulls a different crowd, and the old threshold keeps firing on people who no longer close. The label still gets applied, the count still looks healthy, but the closer's trust quietly erodes. Revisiting is concrete work, not a hunch. Take the leads that qualified over a recent window, split them by which qualifying action tripped the bar, and check which actions preceded a real sale. Actions that led to closes stay or tighten. Actions that never converted get dropped. A course waitlist signup, a store size-fitting request, a service consultation booking: each earns its place only if the people who did it went on to buy. And some businesses never need the stage. A self-serve store checkout or an app install has no MQL to agree on, because nobody needs qualifying once they have bought or installed. The definition only matters when a considered decision sits between interest and purchase.

Why it matters

The MQL is where marketing and the person selling either align or quietly stop trusting each other. Get the definition agreed and revisited against what closed, and follow-up lands on real buyers while both sides believe the count. Leave it as a stale number marketing set alone, and you pass browsers, the closer disengages, and the pipeline number lies. Better ad targeting helps upstream: reach people who fit the buyer and the actions they take carry more signal, but the two teams still have to agree what the signal means.
