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.
