How It Works

1. Lead Ingestion: I have given a free browser extension to scrape leads from Google Maps and import them directly into a Google Sheet.
   1. Business Name
   2. Business Phone Number
   3. Business Emails (From Step 3)
   4. Rating
   5. Reviews Count
   6. Industry
   7. Address
   8. Website
   9. Google Map Link
2. Website Crawling: The n8n workflow reads the leads from your sheet and automatically crawls each website to find all internal pages.
3. Email Extraction: For each page, the workflow intelligently scrapes for email addresses, filtering out image files and other non-relevant data.
4. Enrich and Update:
   • If an email is found, the workflow updates the corresponding row in your Google Sheet with the new email address.
   • If no email is found after crawling the main page and all sub-pages, it marks the lead as "Not Found" so you can easily track your progress.

Requirements

• n8n: A self-hosted or cloud instance of n8n.
• Google Sheets: A Google account with a designated spreadsheet for your Google Maps leads.
• Browser Extension: A free Google Maps scraping extension to get your initial lead data into the Google Sheet.

How to Use

1. Set up your spreadsheet: Use the browser extension to scrape leads from Google Maps and populate your Google Sheet. Make sure the sheet has a column named "Website" and a column named "Processed for Email" (with an initial value of "Pending").
2. Configure the workflow: Import this n8n workflow JSON into your n8n instance and connect your Google Sheets credentials.
3. Run the workflow: Click the "Execute workflow" button to start the process. The workflow will automatically begin crawling websites and enriching your lead list with emails.
