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: 1. Create Google Sheet with two tabs: "searches" and "emails" 2. Add your target search queries to the searches tab (one per row) 3. Connect Google Sheets OAuth credentials in n8n 4. 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.
