Google Maps to Airtable lead scraper with GPT contact extraction from impressum

How it Works

This workflow automates the process of discovering companies in different cities, extracting their contact data, and storing it in Airtable.

1. City Loop (Airtable → Google Maps API)

   • Reads a list of cities from Airtable.
   • Uses each city combined with a search term (e.g., SEO Agency, Berlin) to query Google Maps.
   • Marks processed cities as “checked” to allow safe restarts if interrupted.

2. Business Discovery & Deduplication

   • Searches for businesses via Google Maps Text Search.
   • Checks Airtable to avoid scraping the same company multiple times.
   • Fetches detailed info for each business via Google Maps Place Details API.

3. Impressum Extraction (Website → HTML Parsing)

   • Builds an Impressum page URL for each business.
   • Requests the HTML and cleans out ads, headers, footers, etc.
   • Extracts relevant contact info using an AI extractor (OpenAI node).

4. Contact Information Extraction

   • Pulls out:
     • Decision Maker (Name + Position in one string, if available).
     • Email address (must be valid, containing @).
     • Phone number (international format if possible).
   • Filters out incomplete results (e.g., empty email).

5. Database Storage

   • Writes company data back into Airtable:
     • Company name
     • Address
     • Website
     • Email
     • Phone number
     • Decision Maker (Name + Position)
     • Search term & city used

Setup Steps

1. Prerequisites

• Google Maps API Key with access to:
  • Places API → Text Search + Place Details
• Airtable base with at least two tables:
  • Cities (with columns: ID, City, Country, Status)
  • Companies (for scraped results)
• OpenAI API key (for decision maker + contact extraction).

2. Authentication

• Configure your Airtable API credentials in n8n.
• Set up HTTP Query Auth with your Google Maps API key.
• Add your OpenAI API key in the OpenAI Chat node.

3. Configuration

• In the Airtable “Cities” table, list all cities you want to scrape.
• Define your search term in the “Execute Workflow” node (e.g., SEO Agency).
• Adjust the batch sizes and wait intervals if you want faster/slower scraping (Google API has strict rate limits).

4. Execution

• Start manually or from another workflow.
• The workflow will scrape all companies in each city step by step.
• It can be safely stopped and resumed — cities already marked as processed will be skipped.

5. Results

• Enriched company dataset stored in Airtable, ready for CRM import, lead generation, or further automation.

Tips & Notes

• Always respect GDPR and local laws when handling scraped data.
• The workflow is modular → you can swap Airtable with Google Sheets, Notion, or a database of your choice.
• Add custom filters to limit results (e.g., only companies with websites).
• Use sticky notes inside the workflow to understand each step (mandatory for template publishing).
• Keep an eye on Google Places API costs — queries are billed after the free quota. If you are still within the first 2 months of the Google Cloud Developer free trial, you can benefit from free credits.
