MQL vs SQL — What Is the Difference?

~1 min read

The MQL-to-SQL handoff is one of the most important — and most contentious — processes in B2B revenue operations. Misalignment here is a top driver of poor funnel conversion and sales-marketing friction.

MQL Definition

A Marketing Qualified Lead is a prospect who has engaged enough with your content or product that marketing deems them worth pursuing. Typical MQL criteria:

  • Job title matches your Ideal Customer Profile (ICP)
  • Company size within target range
  • Has requested a demo, downloaded a high-intent asset, or crossed a lead score threshold

SQL Definition

A Sales Qualified Lead is an MQL that a sales rep has reviewed and confirmed meets BANT (or MEDDIC) criteria:

  • Budget: Sufficient budget exists or can be allocated
  • Authority: The contact has or influences the buying decision
  • Need: A genuine business problem that your product solves
  • Timeline: An actionable timeframe within your selling cycle

MQL→SQL Conversion Benchmark

Industry median MQL-to-SQL conversion is 20–40%. Below 20% signals over-permissive MQL criteria (marketing qualifying too broadly). Above 50% can indicate under-permissive criteria (leaving valid leads in marketing nurture too long).

Improving the Handoff

Define MQL criteria in a joint marketing-sales SLA. Review the conversion rate monthly. When rates drop, audit rejected MQLs to recalibrate scoring — not just chase more volume.
