TL;DR:
A Marketing Qualified Lead (MQL) is a prospect who has shown interest in your offering and meets predefined criteria indicating they are more likely to become a customer compared to other leads. MQLs sit between general leads and sales-qualified leads in the funnel.

What is a Marketing Qualified Lead?

An MQL is a contact who has engaged with your marketing content and demonstrated interest or intent that suggests they are ready for more direct engagement from the sales team. Unlike raw leads, MQLs meet certain behavioral and demographic thresholds – such as downloading gated content, repeated site visits or job title relevance – that make them more likely to convert into a customer.

MQL criteria are defined collaboratively by marketing and sales teams and can include:

  • High engagement with key website content
  • Submission of forms (for demos, ebooks, webinars)
  • Matching an ideal customer profile (ICP) based on firmographics or technographics

How MQLs Drive Sales Efficiency

MQLs help prioritize outreach, allowing sales teams to focus on leads that are more likely to convert, increasing efficiency and win rates.

Tracking the journey to MQL status allows marketing teams to attribute pipeline impact to specific campaigns, channels or assets.

Clear MQL criteria create alignment on what qualifies as a “ready” lead, reducing friction between marketing and sales handoff points.

By pre-qualifying leads, MQLs reduce the time sales reps spend filtering out unqualified prospects, shortening the sales cycle.

What to Watch When Defining MQLs

Lead Scoring

MQLs are typically defined using lead scoring models that combine:

  • Behavioral signals: Pageviews, downloads, email opens, ad clicks
  • Demographic or firmographic data: Company size, role, industry, geography

Data Quality

Accurate contact and engagement data is critical. Poor data hygiene can result in false positives or missed opportunities.

Evolving Definitions

The MQL definition is not static – it should be updated regularly based on conversion data and market shifts.

Limitations

  • False positives: Some MQLs never convert to SQLs (Sales Qualified Leads)
  • Over-optimization: Chasing MQL volume can distract from deeper funnel performance (pipeline or revenue)
