Lead generation is the process of attracting and converting strangers or prospects into someone who has expressed interest in your product or service. These prospects are called “leads,” and they are the first stage in your revenue pipeline.
Without lead generation, sales teams would be flying blind. With it, companies can fill their funnel, nurture interest, and convert intention into revenue.
Why Lead Generation Matters
| Benefit | Business Impact |
| Fills the sales funnel | Sustains pipeline and revenue predictability |
| Improves conversion rates | Warmer leads = lower cost per acquisition |
| Builds audience insights | Learn who interacts and why |
| Enables personalization | Target segments with relevant messaging |
| Reduces CAC | Lower customer acquisition cost over time |
A lead generation system is like a fuel pump for the marketing and sales engine.
Types of Leads
| Type | Description |
| Marketing Qualified Lead (MQL) | Engaged but not sales-ready (e.g., downloaded eBook) |
| Sales Qualified Lead (SQL) | Reviewed and deemed ready for a sales call |
| Product Qualified Lead (PQL) | Used the product and shown high intent |
| Cold Lead | Has potential but little interaction so far |
B2B vs B2C Lead Generation
| Category | B2B Leads | B2C Leads |
| Sales Cycle | Longer (weeks/months) | Shorter (minutes/days) |
| Touchpoints | Demos, whitepapers, ABM | Ads, emails, SMS, retargeting |
| Channels | LinkedIn, webinars, email nurturing | Instagram, search ads, referral |
| Qualification | Role, company size, revenue fit | Demographics, purchase intent |
Example 1: B2B SaaS Company Cuts CAC by 41% Using Intent-Based Lead Gen
Company: DocTrackr
Industry: SaaS (Document Management)
Challenge: Paid ads were generating poor-fit leads
Action:
- Integrated G2 and Clearbit for buyer intent data
- Retargeted leads who visited “pricing” and “case study” pages
- Built LinkedIn ad campaigns focused on decision-makers (VP+ roles)
- Created 3 nurture flows based on behavior (time on site, download type)
Results (6 months):
| Metric | Before | After |
| Cost Per Qualified Lead (CPL) | ₹1,920 | ₹1,130 |
| SQL Conversion Rate | 12% | 35% |
| Average Deal Size | ₹58,000 | ₹94,000 |
Example 2: D2C Nutrition Brand Scales to ₹10 Cr Revenue via UGC + Funnels
Company: PlantFuel
Industry: Health & Nutrition (D2C)
Challenge: Low ROAS on performance campaigns
Action:
- Ran influencer UGC (User-Generated Content) ads on Meta
- Built lead magnet quiz: “Find Your Supplement Match”
- Used WhatsApp drip campaigns with nutrition tips & discount codes
- Created loyalty referral programs that generated fresh leads
Results (9 months):
| Metric | Before | After |
| Monthly Leads Generated | 3,200 | 18,700 |
| WhatsApp CTR | 1.6% | 11.9% |
| ROAS (Return on Ad Spend) | 1.3x | 4.6x |
Lead Generation Channels (Inbound vs Outbound)
| Channel Type | Examples | Pros |
| Inbound | SEO, blogs, YouTube, LinkedIn, eBooks | Long-term ROI, higher trust |
| Outbound | Cold email, calls, paid ads, LinkedIn DMs | Faster traction, direct targeting |
Hybrid funnels – where inbound content warms up leads, and outbound closes them — are now standard in high-growth companies.

Lead Recycling and Re-Engagement
Old leads aren’t always dead. They may just be not now leads.
- Run re-engagement email sequences
- Offer updated content (“New 2025 Report”)
- Use custom audiences to retarget stale leads
- Trigger WhatsApp flows on key milestones (1-year since last visit)
Final Takeaway
Lead generation is not just about filling out a form – it’s about earning attention, qualifying it, and converting it over time.
In modern marketing, every blog post, quiz, webinar, or chatbot is a lead magnet – but only the brands that understand their buyer’s journey and use automation + intelligence will consistently win. Whether you sell to consumers or enterprises, your revenue tomorrow is only as good as your leads today.
