A Sales Qualified Lead (SQL) is a prospect who has shown clear buying intent, meets key qualification criteria, and is ready for direct engagement with a sales representative. In 2026, SQLs are identified using AI-driven scoring that blends ICP fit, intent data, engagement signals, and product usage behavior.
Criteria for a Sales Qualified Lead
- Fits the ideal customer profile
- Shows strong intent such as pricing page visits or competitive comparisons
- Responds to outreach or requests a demo
- Engages with product, content, or sales assets
- Demonstrates need, timeline, or defined buying process
- Reaches activation milestones in free or trial environments
- Meets internal qualification frameworks such as BANT or MEDDICC elements
Modern SQL Identification Signals (2026)
- Spikes in third-party intent data
- AI-generated engagement scores
- Product usage patterns indicating readiness to purchase
- Conversation intelligence insights
- Multiple stakeholders engaging from the same account
- Behavioral similarities to past closed-won deals
SQL vs Related Lead Types
MQL (Marketing Qualified Lead)
Shows interest but is not yet ready for sales. SQLs show stronger buying intent.
PQL (Product Qualified Lead)
Demonstrates value through product usage. Many PQLs transition into SQLs when sales readiness increases.
SAL (Sales Accepted Lead)
A lead formally accepted by sales. Some teams use SAL as the step before SQL.
Opportunity
A fully qualified SQL that has entered the sales pipeline for active evaluation.

FAQ
What is the difference between an MQL and an SQL?
MQLs show interest. SQLs show intent and readiness for sales engagement.
Who qualifies SQLs?
Usually SDRs or AI scoring systems, with optional manager review.
Can SQLs revert to nurture?
Yes, if engagement or intent decreases.
Do all SQLs become opportunities?
No, but SQLs convert at much higher rates than MQLs or cold leads.
How does AI improve SQL accuracy?
AI detects intent, usage, and engagement patterns that signal buying readiness earlier and more accurately than manual evaluation.
