Lead Qualification
What Is a Qualified B2B Lead? MQL vs. SQL
Learn to tell curious contacts from real buyers, and stop overloading your sales team with leads that are a poor fit.
By Roberto Monticelli Wydra, Founder & Industrial Marketing Strategist
Direct answer
A qualified B2B lead matches your ideal customer profile (ICP) and has shown interest through their behavior. Qualification has two stages: a Marketing Qualified Lead (MQL), where marketing confirms the company is in the right industry and size range; and a Sales Qualified Lead (SQL), where sales or an SDR confirms a real need, urgency, and budget. Without clear criteria, marketing and sales end up arguing over volume instead of value.
MQL vs. SQL: Where to draw the line
An MQL meets demographic criteria and has downloaded valuable content. An SQL has passed an additional screen, such as a discovery call with an SDR, that confirms they are ready to talk with your team. The goal is for sales to receive SQLs and maximize conversion rates.
Automate qualification with lead scoring
Assign points to each lead action: +10 for downloading an ebook, +50 for visiting the pricing page, and +30 for being a director. When a lead reaches a critical score, route them to sales automatically. This helps the team respond quickly.
Check the ideal customer profile
Qualification is not only about whether a prospect wants to buy. It is also about whether your company should sell to them. If a lead falls below your minimum revenue threshold or works in an industry your solution does not serve, disqualify them, even if their interest is high.
Quick questions
How should we define qualification criteria?
Bring marketing and sales together and ask, “What was the lead like behind our best sale last year?” Use that profile as your gold standard.
What should we do with disqualified leads?
If they fit your ICP but are not ready to buy, add them to a nurture sequence. If they do not fit, remove them so they do not clutter your CRM.
What is a good MQL-to-SQL conversion rate?
It depends on the industry and on your own history, so track your rate over time as your benchmark. If it keeps falling, marketing may be attracting the wrong people.
Should sales qualify leads?
Yes. Sales makes the final assessment. Marketing provides the raw material; sales confirms whether the opportunity is viable.
How should we handle leads who do not respond?
Set a follow-up cadence across email, phone, and LinkedIn before returning the lead to marketing for further nurturing.
