An n8n workflow that finds local businesses on Google Maps, collects their contact details and puts them in a clean, ready-to-use lead sheet.
What it does:
Pulls businesses by niche and city (e.g. plumbers in Virginia) through the Serper.dev Places API
Extracts emails from business websites
Removes duplicates and cleans the data in Google Sheets
Filters leads by criteria like Google review count
Optionally sends personalized outreach with follow-ups and reply detection through Gmail
Tools: n8n, Serper.dev Places API, Google Sheets, Gmail OAuth
Result: [real number, e.g. "X leads collected in Y minutes" or "replaced Z hours of manual copy-paste per week"]
Good fit for agencies and service businesses that need a steady lead list without manual searching.
