| X | Restaurants Madrid | 40.4168 | -3.7038 | ES |

How It Works

Workflow Process

1. Load Search Criteria: Reads queries marked with "X" from keyword_searches sheet
2. Load Existing Data: Retrieves previously processed data for duplicate detection
3. Filter New Searches: Smart merge identifies only new query+location combinations
4. Process Each Location: Sequential processing prevents API overload
5. Configure Parameters: Prepares search parameters from sheet data
6. API Request: Calls RapidAPI to extract business information
7. Parse Data: Structures and cleans all business information
8. Save Results: Stores new leads in stores_data sheet
9. Rate Limiting: 10-second delay between requests
10. Loop: Continues until all new searches are processed

Duplicate Prevention Logic

Search Level: Compares new queries against existing data using query+latitude combination, skipping already processed searches.

Business Level: Each business receives a unique business_id to prevent duplicate entries even across different searches.
