Automated Local Business Lead Generation with Google Maps & GPT-4

This n8n workflow automates the process of generating leads for local businesses by leveraging Google Maps data and enriching it with AI-powered insights from GPT-4. It streamlines the discovery, qualification, and data enhancement of potential business leads.

What it does

This workflow performs the following key steps:

1. Manual Trigger: Initiates the workflow manually, allowing you to control when the lead generation process starts.
2. HTTP Request: Fetches raw business data from a specified API endpoint, likely a Google Maps or similar local business data provider.
3. Edit Fields (Set): Transforms and prepares the raw data for further processing, potentially renaming fields or extracting specific values.
4. Loop Over Items (Split in Batches): Processes the retrieved business data in manageable batches, ensuring efficient handling of large datasets.
5. Wait: Introduces a delay between batches, which can be useful for respecting API rate limits or managing workflow load.
6. Limit: Restricts the number of items processed, allowing for testing or focusing on a specific subset of leads.
7. Remove Duplicates: Ensures that each business lead is unique, preventing redundant processing and data.
8. Split Out: Separates nested data structures into individual items for easier manipulation.
9. Code: Executes custom JavaScript code to further process or transform the data, offering flexibility beyond standard nodes.
10. Filter: Applies conditions to filter out businesses that do not meet specific criteria, helping to qualify leads.
11. Basic LLM Chain (Langchain): Utilizes a Langchain LLM (Large Language Model) to process and understand the business data.
12. OpenAI Chat Model (Langchain): Specifically uses an OpenAI Chat Model (like GPT-4) to generate insights, summaries, or other enriched data points for each business.
13. Structured Output Parser (Langchain): Parses the output from the OpenAI Chat Model into a structured format (e.g., JSON), making it easy to use in subsequent steps.
14. Sticky Note: Provides a place for notes or comments within the workflow, aiding documentation and understanding.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• API Key for Google Maps (or similar local business data provider): An API key for the service used in the "HTTP Request" node to fetch business data.
• OpenAI API Key: An API key for OpenAI to utilize their Chat Model (e.g., GPT-4) for lead enrichment.
• Langchain Integration: Ensure the @n8n/n8n-nodes-langchain package is installed and configured in your n8n instance.

Setup/Usage

1. Import the Workflow: Import the provided JSON into your n8n instance.
2. Configure Credentials:
   • Set up credentials for your Google Maps (or equivalent) API in the "HTTP Request" node.
   • Configure your OpenAI API key within the "OpenAI Chat Model" node.
3. Customize HTTP Request: Adjust the URL and parameters in the "HTTP Request" node to target your desired geographical area and business categories on Google Maps.
4. Refine Filters: Modify the "Filter" node to define your specific lead qualification criteria (e.g., minimum rating, specific keywords in description).
5. Adjust LLM Prompts: Customize the prompts within the "Basic LLM Chain" and "OpenAI Chat Model" nodes to guide the AI in generating the desired insights (e.g., "Summarize business services," "Identify unique selling points").
6. Run the Workflow: Execute the workflow manually using the "When clicking ‘Execute workflow’" trigger.
7. Review Outputs: Inspect the output of the final nodes to see the enriched lead data. You can then integrate this data with other systems (e.g., CRM, Google Sheets) using additional n8n nodes.
