Google Maps Email Scraper System
Categories: Lead Generation, Web Scraping, Business Automation
This workflow creates a completely free Google Maps email scraping system that extracts unlimited business emails without requiring expensive third-party APIs. Built entirely in N8N using simple HTTP requests and JavaScript, this system can generate thousands of targeted leads for any industry or location while operating at 99% free cost structure.
Benefits
- Zero API Costs - Operates entirely through free Google Maps scraping without expensive third-party services
- Unlimited Lead Generation - Extract emails from thousands of Google Maps listings across any industry
- Geographic Targeting - Search by specific cities, regions, or business types for precise lead targeting
- Complete Automation - From search query to organized email list with minimal manual intervention
- Built-in Data Cleaning - Automatic duplicate removal, filtering, and data validation
- Scalable Processing - Handle hundreds of businesses per search with intelligent rate limiting
How It Works
Google Maps Search Integration:
- Uses strategic HTTP requests to Google Maps search URLs
- Processes search queries like "Calgary + dentist" to extract business listings
- Bypasses API restrictions through direct HTML scraping techniques
Intelligent URL Extraction:
- Custom JavaScript regex patterns extract website URLs from Google Maps data
- Filters out irrelevant domains (Google, schema, static files)
- Returns clean list of actual business websites for processing
Smart Website Processing:
- Loop-based architecture prevents IP blocking through intelligent batching
- Built-in delays and redirect handling for reliable scraping
- Processes each website individually with error handling
Email Pattern Recognition:
- Advanced regex patterns identify email addresses within website HTML
- Extracts contact emails, info emails, and administrative addresses
- Handles multiple email formats and validation patterns
Data Aggregation & Cleaning:
- Automatically removes duplicate emails across all processed websites
- Filters null entries and invalid email formats
- Exports clean, organized email lists to Google Sheets
Required Google Sheets Setup
Create a Google Sheet with these exact column headers:
Search Tracking Sheet:
searches
- Contains your search queries (e.g., "Calgary dentist", "Miami lawyers")
Email Results Sheet:
emails
- Contains extracted email addresses from all processed websites
Setup Instructions:
- Create Google Sheet with two tabs: "searches" and "emails"
- Add your target search queries to the searches tab (one per row)
- Connect Google Sheets OAuth credentials in n8n
- Update the Google Sheets document ID in all sheet nodes
The workflow reads search queries from the first sheet and exports results to the second sheet automatically.
Business Use Cases
- Local Service Providers - Find competitors and potential partners in specific geographic areas
- B2B Sales Teams - Generate targeted prospect lists for cold outreach campaigns
- Marketing Agencies - Build industry-specific lead databases for client campaigns
- Real Estate Professionals - Identify businesses in target neighborhoods for commercial opportunities
- Franchise Development - Research potential markets and existing competition
- Market Research - Analyze business density and contact information across regions
Revenue Potential
This system transforms lead generation economics:
- $0 per lead vs. $2-5 per lead from paid databases
- Process 1,000+ leads daily without hitting API limits
- Sell as a service for $500-2,000 per industry/location
- Perfect for agencies offering lead generation to local businesses
Difficulty Level: Intermediate
Estimated Build Time: 1-2 hours
Monthly Operating Cost: $0 (completely free)

Set Up Steps
Basic Workflow Architecture:
- Set up manual trigger for testing and Google Sheets integration
- Configure initial HTTP request node for Google Maps searches
- Enable SSL ignore and response headers for reliable scraping
URL Extraction Code Setup:
- Configure JavaScript code node with custom regex patterns
- Set up input data processing from Google Maps HTML responses
- Implement URL filtering logic to remove irrelevant domains
Website Processing Pipeline:
- Add "Split in Batches" node for intelligent loop processing
- Configure HTTP request nodes with proper delays and redirect handling
- Set up error handling for websites that can't be scraped
Email Extraction System:
- Implement JavaScript code node with email-specific regex patterns
- Configure email validation and format checking
- Set up data aggregation for multiple emails per website
Data Cleaning & Export:
- Configure filtering nodes to remove null entries and duplicates
- Set up "Split Out" node to aggregate emails into single list
- Connect Google Sheets integration for organized data export
Testing & Optimization:
- Use limit nodes during testing to prevent IP blocking
- Test with small batches before scaling to full searches
- Implement proxy integration for high-volume usage
Advanced Optimizations
Scale the system with:
- Multi-Page Scraping: Extract URLs from homepages, then scrape contact pages for more emails
- Proxy Integration: Add residential proxies for unlimited scraping without rate limits
- Industry Templates: Create pre-configured searches for different business types
- Contact Information Expansion: Extract phone numbers, addresses, and social media profiles
- CRM Integration: Automatically add leads to sales pipelines and marketing sequences
Important Considerations
- Rate Limiting: Built-in delays prevent IP blocking during normal usage
- Scalability: For high-volume usage, consider proxy services for unlimited requests
- Compliance: Ensure proper usage rights for extracted contact information
- Data Quality: System includes filtering but manual verification recommended for critical campaigns
