How It Works

Workflow Process

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