3. What is B2B Lead Generation? A Modern Definition

B2B lead generation is the process of identifying, attracting, and converting potential business customers into sales qualified leads (SQLs) using targeted multi-channel strategies, data, and technology.

Key Terms You Should Know

• Lead: A business contact expressing some level of interest
• Qualified Lead: A lead matching your Ideal Customer Profile (ICP) and showing intent
• MQL (Marketing Qualified Lead): Engaged by marketing but not yet sales-ready
• SQL (Sales Qualified Lead): Ready for direct outreach or a sales call
• ICP (Ideal Customer Profile): A detailed representation of your perfect client (think company size, industry, location, decision-maker titles, etc.)
• ABM (Account-Based Marketing): Personalizing outreach to specific, high-value accounts

Why “Lead Quality” Matters More Than Ever

• Low-quality leads = High wasted effort, low close rates
• High-quality, well-nurtured leads = Shorter sales cycles, higher CLV (Customer Lifetime Value)

4. Nurture:
