Marketing Qualified Lead (MQL)

What MQL actually means

An MQL is a definitional artifact, not a natural category. It exists because marketing and sales needed a shared line for when a lead is worth a human's time. That line is typically drawn using firmographic fit and behavioral scoring. Because the definition is internal, MQL counts are only meaningful inside one company and only comparable over time if the definition has not quietly moved.

Worked example

A company generates 2,000 leads a month. Its criteria require a company size above 50 employees, a target job function, and at least one high-intent action such as a pricing page visit or demo request. 240 leads clear that bar, a 12 percent MQL rate. Sales accepts 180 of them, revealing a 25 percent disagreement rate on the definition itself.

Why the board cares

Boards do not care about MQL volume. They care about MQL-to-revenue conversion holding steady while volume grows. When MQLs rise 40 percent and pipeline stays flat, either the definition loosened or the traffic mix degraded, and both are marketing problems rather than sales problems.

Common mistakes

• Changing scoring thresholds without restating history, which manufactures a growth trend out of arithmetic.
• Treating MQL count as a primary marketing goal, which reliably incentivizes volume over quality.
• Failing to agree the definition with sales, which guarantees a permanent argument about lead quality.
