This n8n workflow is a sophisticated B2B Lead Generation Scraper. It automates the entire journey from discovering businesses on Google Maps to extracting, scoring, and saving high-quality contact emails. Here is a breakdown of the workflow stages: Stage 1: Google Maps Search & Pagination The workflow starts with a list of search queries (e.g., "Dentist New York"). Looping: It processes each query one by one. Smart Pagination: Google Maps usually limits results per page. This workflow detects the nextPageToken and automatically re-calls the API until all available businesses for that query are collected. Filtering: It immediately filters out closed businesses, keeping only those marked as "OPERATIONAL". Stage 2: Deep Web Scraping For every business found with a website, the workflow performs a two-step crawl: Homepage Fetch: It visits the main URL to find immediate contact info. Contact Page Discovery: A code node scans the homepage for links containing keywords like "Contact", "About", "Team", or "Impressum". It then visits these specific sub-pages to find hidden emails. Stage 3: Email Quality Control & Scoring This is the most advanced part of the logic. Instead of just grabbing any email, it uses a Scoring System to rank them: The Filter: It removes technical or junk emails (e.g., sentry@, noreply@, or image files disguised as emails). The Scorecard: +30 Points: Domain match (e.g., info@company.com matches www.company.com). +20 Points: Personal touch (detects dots or names like john.doe@). -40 Points: Generic prefixes (penalizes info@, admin@, sales@). -25 Points: Free providers (penalizes @gmail.com, @yahoo.com). Selection: It sorts all found emails by score and keeps only the top-ranked email for each business. Stage 4: Final Output Deduplication: It ensures no duplicate businesses are added to your list, even if they appeared in multiple search queries. Data Storage: The final, cleaned data—including Business Name, Address, Phone, Website, and the Best Email—is appended to a Google Sheet. An n8n automation workflow template by Jannik Hiller.
