What it means
An MQL is defined by rules the business agrees in advance, not by gut feel. Those rules usually mix who the person is (job title, company size, industry) with what they have done, such as visiting the pricing page, requesting a demo, or opening five emails in a fortnight.
MQL counts matter because they are the first point in the funnel where marketing spend turns into something the sales team can act on. If you only track total leads you flatter yourself, and if you only track closed deals you find out about a broken campaign six months too late.
Most teams score contacts out of 100 and set a threshold, say 60 points, above which a contact is promoted to MQL. Points come from fit, so a head of finance at a 500-person firm scores higher than a student, and from behaviour, where a demo request is worth far more than a single blog visit.
The number that actually matters is not MQL volume but the rate at which MQLs turn into opportunities, because it is easy to manufacture MQLs simply by loosening the threshold. Sales teams stop trusting the label within weeks if half the contacts they call have never heard of the product.
Common variants include the sales qualified lead, which sales has formally accepted, and the product qualified lead, someone already using a free version of the software. Many companies now agree a single shared definition across marketing and sales so the two sides stop arguing about where the handover sits.
In practice
Real-world examples.
Example
A payroll software firm runs a webinar that attracts 1,200 registrations. Only the 180 attendees who work in HR at companies with more than 50 staff and who stayed past the demo section are marked as MQLs. The rest stay in the nurture list and receive monthly emails until their behaviour changes.
Example
A commercial roofing contractor treats any enquiry from a facilities manager with a building over 2,000 square metres as an MQL, regardless of scoring. Anything smaller goes to a self-serve quote form. This crude rule works because the sales team is small and only wants larger jobs.
Example
A fitness equipment supplier notices its MQL count doubled after a discount campaign, but the sales team closes fewer deals than the previous quarter. On review, the campaign attracted individual consumers rather than gym operators, so the scoring model is rewritten to weight business email domains far more heavily.
Think of it
“MQLs are leads that marketing has vetted and passed to sales-qualified prospects.
Formula
Calculation
MQL conversion rate = (MQLs / total new leads) x 100. Cost per MQL = marketing spend / number of MQLs. Suppose a business software company generates 4,000 new leads in March and 900 of them cross the 60-point scoring threshold. The MQL conversion rate is 900 / 4,000 = 0.225, or 22.5%. If marketing spent $180,000 that month, the cost per MQL is $180,000 / 900 = $200. If sales then accepts 25% of those MQLs as real opportunities, that is 900 x 0.25 = 225 sales qualified leads for the quarter's pipeline.Case study
Seen in the real world.
In this illustrative example, Harborline Analytics, a fictional data reporting company, set marketing a target of 1,000 MQLs a quarter. Marketing hit the number easily by counting every e-book download, and the team celebrated. Sales, working through the list, found that fewer than one in twenty contacts had any buying authority.
The two teams rebuilt the definition together. A contact now needed a business email address, a company of at least 100 employees, and one high-intent action such as a pricing page visit or a demo request. Quarterly MQLs fell from 1,000 to 340, which felt like a step backwards on the dashboard.
The pipeline told a different story. Opportunities created from MQLs rose from 48 to 91, and the cost per opportunity fell by more than a third. The fictional board stopped asking about lead volume and started asking about the conversion rate instead.
Watch out
Common mistakes.
- Treating every form fill as an MQL, which inflates the number and destroys the sales team's trust in the label within a single quarter.
- Scoring only on behaviour and ignoring fit, so an enthusiastic student who reads every blog post outranks a quiet buyer with a budget.
- Setting the MQL target as a volume goal with no matching conversion target, which quietly rewards marketing for sending sales the wrong people.
Questions
People also ask.
What is the difference between an MQL and a sales qualified lead?
An MQL is marketing's judgement that the contact is worth a call, while a sales qualified lead is one the sales team has looked at and formally accepted as a real opportunity.
How often should the MQL definition be reviewed?
Once or twice a year is sensible, and immediately after any large shift in product, pricing or target market, because an old definition quietly stops matching who actually buys.
Can a contact become an MQL more than once?
Yes, and most systems allow recycling, so a lead that went cold can be promoted again when new buying behaviour appears months later.
