How to Build an Automated B2B Lead Generation System with n8n and Web Scraping

#automation #n8n #webdev #tutorial

Need to find qualified B2B leads automatically? Here's how I built a system that finds, qualifies, and enriches leads using n8n workflows and web scrapers.

The Problem

Manual lead research costs $15-30/hour per SDR. An average SDR finds 20-30 qualified leads per day. That's $500+/day in labor costs.

I automated it: 500+ qualified leads per day for $0.03 each.

Architecture

Data Sources → Web Scrapers → n8n Workflow → AI Qualification → CRM/Sheets

Step 1: Data Collection (Web Scrapers)

I built scrapers for the sources that matter:

Company directories — Extract company name, website, employee count, industry
Job boards — Companies hiring = companies growing = companies buying
Review platforms — Trustpilot/G2 reviews reveal pain points
Social media — Reddit/HN discussions show what people need
News — Google News for funding rounds, launches, expansions

All scrapers available free on Apify Store (77 scrapers covering these sources).

Step 2: n8n Workflow

Schedule Trigger (daily)
  → HTTP Request (run scraper via Apify API)
  → Extract results
  → AI Function (GPT-4/Claude for lead scoring)
  → Filter (score > 70)
  → Google Sheets (add qualified leads)
  → Email notification (daily summary)

Step 3: AI Lead Scoring

Use Claude or GPT-4 to score each lead:

{
  "company": "TechCorp",
  "employees": 150,
  "industry": "SaaS",
  "hiring_signal": true,
  "recent_funding": true,
  "score": 87,
  "reason": "Growing SaaS company, recently funded, actively hiring — high likelihood of needing our services"
}

Step 4: Enrichment

For qualified leads (score > 70), enrich with:

Decision-maker contacts (LinkedIn scraping)
Technology stack (BuiltWith/Wappalyzer)
Social media presence
Recent news mentions

Results

500+ leads/day processed automatically
70+ qualified leads/day after AI scoring
Cost: ~$0.03/lead (API costs only)
ROI: 10x-50x vs manual research
