What is B2B Lead Generation?
Definition: B2B lead generation is the process of attracting, identifying, and cultivating potential buyers for your business’s products or services.
Key nuances for B2B:
- Leads often represent buying committees, not individuals.
- Average deal size and cycle are much larger/longer than B2C.
- Qualification, nurturing, and personalization are much more complex.
Types of B2B Leads
- Marketing Qualified Leads (MQLs): Engaged with inbound content, fit initial criteria.
- Sales Qualified Leads (SQLs): Vetted by sales, considered ready for direct engagement.
- Product Qualified Leads (PQLs): Used a product/feature and show high buying intent (common in SaaS).
The B2B Lead Generation Funnel
- Awareness: Brand/content discovery
- Engagement: Information exchange (form fills, downloads, webinar registration)
- Qualification: Scoring, segmentation, and hand-off
- Nurture: Targeted campaigns to educate and build trust
- Conversion: Opportunity creation and sales engagement
- Closed/Won: Sale is made; lead becomes a customer
Key Challenges in B2B Lead Gen
While demand is growing, so are the obstacles. In 2025, B2B marketers consistently report:
