Marketing Qualified Lead (MQL)

A marketing qualified lead is a lead that has met specific criteria defined by your marketing and sales teams — based on both demographic fit and behavioral engagement — indicating they are likely interested enough to warrant direct sales follow-up.

The MQL is arguably the most debated concept in GTM operations. When defined well, MQLs create a clear handoff point between marketing and sales that ensures reps receive leads worth their time. When defined poorly (or when marketing games the numbers), MQLs become a vanity metric that frustrates sales and wastes resources.

MQL criteria typically combine fit signals and engagement signals. Fit signals include: matches your ICP (right industry, company size, job title). Engagement signals include: downloaded multiple pieces of content, attended a webinar, visited the pricing page, or reached a specific lead score threshold.

For example, a contact might become an MQL when they: work at a company with 100+ employees (fit), hold a director-level or above title (fit), AND have visited the website 3+ times in the past 30 days and downloaded at least one piece of gated content (engagement). Both fit and engagement should be required — a perfect-fit contact who visited once isn’t ready, and a highly engaged intern doesn’t have buying power.

The health of your MQL program shows up in the MQL-to-SQL conversion rate. If sales accepts and qualifies more than 30% of MQLs, your criteria are well-calibrated. Below 15%, your threshold is too low and you’re passing junk. Above 50%, your threshold might be too high and you’re missing opportunities.

Review MQL criteria quarterly with both sales and marketing stakeholders. Analytics tools help you track MQL conversion rates and continuously refine your scoring thresholds.
