The MQL was designed to identify contacts ready for sales engagement. The intent was sound. What happened in practice is that it became a volume target.
When marketing teams are measured on MQL count, every program decision optimizes for more contacts. Higher-volume sources get funded. Quality signals that would reduce volume get deprioritized. The result: more contacts, lower conversion rates, and a sales team that stops trusting the metric.
‘The Metric Replacement Gap’ is what follows: every senior demand gen leader knows the MQL is broken. Few have replaced it with something sales, finance, and marketing will all accept. The gap is not awareness. It is the absence of a replacement framework that survives the quarterly review.
At Forrester’s B2B Summit North America 2026, MQLs were challenged as an insufficient proxy for revenue confidence, even where teams still report them. Stronger measures included opportunities created, opportunities accepted by sales, stage progression, pipeline value, account quality, and business outcome alignment. The change was not about better contacts in isolation. It came from changing what the team optimized toward.
The current state of most B2B demand gen programs reflects this measurement gap in a different form. Only 28% of marketing professionals consider their attribution strategy very successful in achieving strategic objectives, while 66% call it only somewhat successful (Ascend2, 2024 Marketing Attribution Survey). Attribution and lead-stage metrics are different problems, but they share the same root cause: teams are still measuring what’s easy to count rather than what connects to revenue. When the primary metric does not connect to revenue, neither does the budget justification.
