Lead Generation with AI Web Scraping: Extract Contacts at Scale

Lead Generation with AI Web Scraping: Extract Contacts at Scale

Author 1

Marco Vinciguerra

In today's competitive business landscape, lead generation is the lifeblood of growth. But manually searching for prospects, copying contact details, and building lead lists is incredibly time-consuming. AI-powered web scraping changes everything.

The Challenge of Modern Lead Generation

Traditional lead generation methods are slow and expensive:

  • Manual research takes hours per prospect
  • Purchased lead lists are often outdated or inaccurate
  • LinkedIn limits restrict how many profiles you can view
  • Data entry errors corrupt your CRM data

A smart lead generation tool powered by AI can extract accurate contact information at scale, giving your sales team a constant flow of qualified prospects.

How ScrapeGraphAI Transforms Lead Generation

ScrapeGraphAI's AI understands the context of web pages, making it perfect for extracting business information from any source—company websites, directories, social profiles, and more.

Extract Company Information

from scrapegraph_py import Client
 
# Initialize the client with your API key
client = Client(api_key="your-api-key-here")
 
# SmartScraper request to extract company details
response = client.smartscraper(
    website_url="https://www.hubspot.com/company/about",
    user_prompt="Extract company name, description, industry, headquarters location, employee count, founded year, and all contact information including email, phone, and social media links"
)
 
print("Result:", response)

Example Output:

{
  "company_name": "HubSpot",
  "description": "HubSpot is a CRM platform that helps companies grow better",
  "industry": "Software / SaaS",
  "headquarters": "Cambridge, Massachusetts",
  "employee_count": "7,000+",
  "founded_year": "2006",
  "social_media": {
    "linkedin": "https://linkedin.com/company/hubspot",
    "twitter": "https://twitter.com/HubSpot"
  }
}

Search for Leads by Industry

Use SearchScraper to find companies in specific industries:

from scrapegraph_py import Client
 
# Initialize the client
client = Client(api_key="your-api-key-here")
 
# SearchScraper request to find companies
response = client.searchscraper(
    user_prompt="Find B2B SaaS companies in New York with 50-200 employees, extract company name, website, and description",
    num_results=10
)
 
print("Result:", response)

Build Lead Lists from Directories

from scrapegraph_py import Client
 
client = Client(api_key="your-api-key-here")
 
# Extract multiple businesses from a directory page
response = client.smartscraper(
    website_url="https://clutch.co/agencies/digital-marketing/new-york",
    user_prompt="Extract all businesses listed: company name, phone number, address, website URL, rating, and number of reviews"
)
 
print("Result:", response)

Building a Complete Lead Generation System

Step 1: Define Your Ideal Customer Profile

Before scraping, know who you're looking for:

target_criteria = {
    "industries": ["SaaS", "Marketing Agency", "E-commerce"],
    "company_size": "10-500 employees",
    "locations": ["United States", "United Kingdom", "Canada"],
    "technologies": ["Salesforce", "HubSpot", "Shopify"]
}

Step 2: Identify Data Sources

Different sources for different data:

data_sources = {
    "company_directories": [
        "https://www.crunchbase.com/",
        "https://www.g2.com/",
        "https://clutch.co/"
    ],
    "job_boards": [
        "https://www.indeed.com/",
        "https://www.linkedin.com/jobs/"
    ],
    "industry_lists": [
        "https://www.inc.com/inc5000",
        "https://www.forbes.com/lists/"
    ]
}

Step 3: Extract and Enrich Data

from scrapegraph_py import Client
 
client = Client(api_key="your-api-key-here")
 
def extract_company_leads(directory_url):
    # First, get list of companies
    companies = client.smartscraper(
        website_url=directory_url,
        user_prompt="Extract all company names and their profile URLs from this page"
    )
    
    leads = []
    
    # Then enrich each company
    for company in companies.get("companies", []):
        if company.get("profile_url"):
            details = client.smartscraper(
                website_url=company["profile_url"],
                user_prompt="""Extract:
                - Company name
                - Website URL
                - Description
                - Industry
                - Employee count
                - Headquarters location
                - Founded year
                - Key executives with their titles
                - Contact email
                - Phone number
                - Social media profiles
                """
            )
            leads.append(details)
    
    return leads

Step 4: Find Decision Makers

def find_decision_makers(company_website):
    # Look for team/about pages
    response = client.smartscraper(
        website_url=f"{company_website}/about",
        user_prompt="""Find all team members, especially:
        - CEO, Founder, Owner
        - VP of Sales, Sales Director
        - VP of Marketing, CMO
        - CTO, VP of Engineering
        
        Extract their names, titles, and any contact information or LinkedIn profiles"""
    )
    
    return response

Best Practices for Lead Generation Scraping

1. Quality Over Quantity

100 well-researched leads beat 10,000 random contacts. Use AI to extract rich data, not just email addresses.

2. Verify Email Addresses

Scraped emails should be verified before outreach to protect your sender reputation.

3. Respect Privacy

Follow GDPR and other regulations. Focus on business contact information, not personal data.

4. Keep Data Fresh

Contact information changes constantly. Schedule regular updates to your lead database.

5. Enrich Continuously

Start with basic data, then layer on additional information as leads progress through your funnel.

Integration with Your Sales Stack

Export your leads to popular CRMs:

import csv
 
def export_to_csv(leads, filename="leads.csv"):
    if not leads:
        return
    
    keys = leads[0].keys()
    
    with open(filename, 'w', newline='') as f:
        writer = csv.DictWriter(f, fieldnames=keys)
        writer.writeheader()
        writer.writerows(leads)
 
# Export for CRM import
export_to_csv(leads, "new_leads.csv")
