What Is a Marketing Qualified Lead (MQL)? MQL Definition & Examples
Discover the definition of Marketing Qualified Lead (MQL), key criteria, real-world examples, and best practices in digital marketing lead generation.


A Marketing Qualified Lead (MQL) is a prospect identified by the marketing team as more likely to become a customer based on specific behavioral, demographic, and engagement criteria.
In-Depth Explanation
MQLs are not just any leads who show casual interest—they are individuals or organizations that have met tailored, measurable criteria indicating they are ready for deeper sales engagement. Typical signals include visiting high-value web pages, downloading gated content, signing up for webinars, or interacting with targeted campaigns. The precise definition and scoring system are established collaboratively by marketing and sales, ensuring both teams agree on what constitutes true purchase intent source.
Key Components of MQL Qualification
1. Lead Scoring Rubric
- Demographic/Firmographic Fit: Role, company size, industry
- Behavioral Signals: Downloads, demo requests, repeat site visits
- Engagement Level: Email opens/clicks, webinar participation, social interaction
Criteria | Example Action | Points |
---|---|---|
Job Title (decision maker) | Yes | +20 |
Downloaded Case Study | Yes | +15 |
Attended a Webinar | Yes | +10 |
Visited Pricing Page | Yes | +10 |
Unsubscribed from Email | Yes | -10 |
Threshold for MQL: Customizable, e.g., ≥ 40 points.
2. Lifecycle Stage
A potential customer becomes an MQL after surpassing the threshold, meaning the lead is engaged and closely matches the Ideal Customer Profile (ICP). The next stage, the Sales Qualified Lead (SQL), is determined once the sales team further vets readiness (e.g., confirmed need, budget, and buying timeline).
Practical Example: SaaS Scenario
Imagine a B2B software company:
- Initial Lead: John, a mid-size company IT manager, downloads a white paper (+15), attends a live demo (+10), and visits the pricing page repeatedly (+10). He has a decision-maker title (+20), totaling 55 points.
- MQL Transition: John passes the MQL threshold and is handed to sales.
- SQL Evaluation: Sales confirms his company’s budget and current need. John is now an SQL and enters the proposal stage.
Why MQLs Matter
Identifying the right MQLs streamlines the sales process, improves team alignment, and increases conversion rates. Modern lead scoring often uses AI for predictive analytics, adjusting criteria dynamically as more conversion data is collected source.
