MARKETING GLOSSARY
What Is a Marketing Qualified Lead (MQL)?
DIRECT ANSWER
A marketing qualified lead (MQL) is a prospect who has engaged with marketing content or signals at a level that indicates readiness for sales outreach, as defined by a shared marketing-sales scoring model. MQL status is typically assigned by lead score thresholds based on demographic fit and behavioral engagement, triggering a handoff to sales.
How MQL Scoring Works
MQL scoring combines two dimensions: fit (does this person match the ideal customer profile?) and intent (have they engaged in ways that signal purchase consideration?). Fit attributes — company size, industry, job title, geography — are weighted by how closely they match the ICP. Intent behaviors — visiting the pricing page, downloading a product comparison guide, attending a live demo webinar — carry higher weights than passive behaviors like reading a blog post. A prospect crosses the MQL threshold when their cumulative score exceeds a negotiated cutoff, typically between 50 and 100 points in common models.
Score decay is a frequently overlooked element. A prospect who downloaded a whitepaper 18 months ago and never returned is not MQL-ready, but many models don't time-decay older signals. Best-practice implementations reduce score by 20–30% per quarter of inactivity, ensuring the MQL pool reflects current intent rather than historical curiosity. Autonomous scoring systems can apply decay continuously rather than through batch nightly jobs.
MQL-to-SQL Conversion and Where the Model Breaks Down
Industry benchmarks for MQL-to-SQL (sales qualified lead) conversion range from 13% to 27% across B2B SaaS, with higher-intent signals (free trial, demo request) converting at 40–60% and lower-intent signals (content downloads) converting at 5–15%. If your MQL-to-SQL rate is below 10%, the scoring model is generating noise; above 35%, you're likely setting the threshold too high and leaving pipeline in the queue.
The MQL model breaks down when marketing and sales define quality differently. Marketing optimizes for MQL volume (often tied to targets), while sales prioritizes accounts with real budget and authority. This misalignment produces the chronic complaint from sellers that 'marketing MQLs are garbage.' The structural fix is a shared pipeline-quality SLA — both teams agree on a minimum MQL-to-opportunity conversion rate and review it monthly. Some high-performing GTM teams have abandoned MQLs entirely in favor of account-level engagement scoring and buying-committee identification, which better reflects B2B buying dynamics.
FAQ
Marketing Qualified Lead (MQL) — common questions
What is the difference between an MQL and an SQL?
An MQL is qualified by marketing based on scoring criteria. An SQL (sales qualified lead) is an MQL that a sales rep has spoken to and confirmed has real budget, authority, need, and timeline (BANT or equivalent). SQLs become opportunities in the CRM pipeline; most MQLs do not.
How should MQL thresholds be set?
Run a historical regression: pull the last 12 months of closed-won deals and map what score each account had at the point of sales outreach. The score at which conversion rates materially increase is your empirical threshold. Revisit quarterly — ICP and buying behavior shift, and static thresholds degrade.
Are MQLs still relevant in a product-led growth model?
In PLG, MQLs are replaced or supplemented by PQLs (product qualified leads) — accounts that have hit specific in-product activation milestones. Mixing MQL and PQL criteria in one model is common in hybrid PLG-SLG motions, but requires careful weighting to avoid double-counting.
