A marketing qualified lead has shown enough interest for marketing follow-up. A sales qualified lead has been checked by sales and may be a real buying opportunity.
The MQL-to-SQL framework defines when a lead transitions from marketing ownership to sales ownership. Getting this handoff right is one of the most impactful improvements a B2B company can make.
An MQL is a lead that has demonstrated interest through marketing engagement: downloading content, attending a webinar, visiting pricing pages, or meeting lead scoring thresholds. Marketing has qualified them as potentially valuable based on behavior and firmographic data.
An SQL is a lead that sales has personally vetted and confirmed as a real opportunity. This typically requires a conversation where the sales rep validates budget, authority, need, and timeline (BANT). An SQL has a defined problem, the authority to buy, and a realistic timeline.
The conversion rate from MQL to SQL is one of the most important metrics in B2B marketing. Benchmark it against your own history rather than a borrowed industry average. If the rate drops, either marketing is sending unqualified leads or sales is not following up effectively. Both are fixable.
The MQL-to-SQL handoff is where most B2B companies lose a large share of their pipeline. Marketing generates leads that sales ignores. Sales complains about lead quality. The real problem is usually unclear definitions and inconsistent follow-up processes.
Not having agreed-upon MQL and SQL definitions between marketing and sales teams
Setting MQL thresholds too low, which floods sales with unqualified leads
Not tracking MQL-to-SQL conversion rate, so neither team knows if the handoff is working
Lead nurturing keeps in touch with potential customers until they are ready to decide. It uses relevant information and timely follow-up instead of repeated sales pressure.
Demand generation helps the right people learn about a business and become interested in buying. It can include useful content, search, paid media, and events.
AI lead qualification sorts incoming leads using approved fit and intent signals before a person decides what follow-up is appropriate.
Sales enablement gives sellers the information, tools, training, and proof they need to help buyers make a decision.
There is no reliable industry-wide number: benchmark it against your own history rather than a borrowed average. A rate that is falling, or that lags what your own team has hit before, usually indicates a lead quality or follow-up speed problem. The most common fix is tightening MQL criteria and implementing faster sales follow-up (under 5 minutes for inbound leads).
Sales decides. Marketing's job is to generate MQLs that meet agreed-upon criteria. Sales reviews each MQL and either accepts it (becoming an SQL), rejects it (with a reason), or sends it back to marketing for further nurturing. This requires a shared definition and regular calibration meetings.
