Why your MQLs do not convert

The short answerAn MQL that does not convert is rarely a bad lead. It is usually a lead that met a threshold nobody agreed to, arrived without the context that made it interesting, sat for three days before anyone called, or was already being worked by another rep under a different record. Fix those four and conversion moves without changing a single campaign.

Nobody agreed what qualified means

Ask the head of marketing and the head of sales to write down the MQL definition separately. If the two answers differ, and they usually do, then every argument about lead quality is really an argument about a threshold that was set once and never renegotiated.

The fix is boring and works: one definition, written down, owned by both, reviewed monthly against what actually converted.

The context gets dropped at the handoff

A lead that downloaded a pricing comparison and attended a demo webinar is a different animal to one that grabbed a blog PDF. If both arrive in the CRM as "MQL" with the source field blank, the rep treats them the same, because they have nothing to treat them differently with.

Speed to first touch

The single most reliable predictor of whether an inbound lead converts is how fast somebody contacts it. Most mid market teams measure this in days without realising it. Routing rules that depend on a nightly job, or a round robin that assigns to someone on holiday, turn a hot lead into a cold one before anyone speaks to it.

Duplicates hide the real history

If the same company exists three times, the rep calling the new MQL cannot see that another rep spoke to that account six weeks ago and got a firm no. So the conversation starts from zero, sounds uninformed, and converts worse.

What to measure before blaming the leads

Median hours from form submit to first human contact
Percentage of MQLs with a populated source field
Duplicate rate on accounts created in the last quarter
Conversion by source, not in aggregate, for the last two quarters

Questions

What is a good MQL to SQL conversion rate?

It varies enormously by motion and source, which is why the useful comparison is your own rate by source over time rather than an industry benchmark.

Should marketing or sales own the MQL definition?

Both, in writing, reviewed on a set cadence. Single ownership is how the definition drifts away from what the other team will accept.

How fast should we contact an inbound lead?

Hours rather than days. The exact number matters less than the direction, and most teams discover their median is far worse than they assumed once they measure it.

Is this a lead quality problem or a process problem?

Measure speed to first touch, source completeness and duplicate rate first. If those three are poor, you cannot yet say anything about quality.
