This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

How It Works

This n8n workflow automatically discovers high-quality business leads from Reddit posts by analysing posts across targeted subreddits.

  1. Loads your business profile from a connected Google Sheet.
  2. Uses AI to identify relevant subreddits where your potential customers engage.
  3. Generates intent-based Reddit search queries based on your services, keywords, and client pain points.
  4. Searches Reddit in real time using the generated queries.
  5. Classifies posts based on whether they show lead potential.
  6. Analyses high-potential posts for service-fit, urgency, and estimated value.
  7. Filters and scores leads to prioritize high-conversion opportunities.
  8. Saves the most promising leads to a dedicated Google Sheet.
  9. Sends Slack alerts to notify your sales team for immediate follow-up.

Requirements

Before using this workflow, ensure the following services are connected and configured:

  1. Google Sheets (OAuth2): Reads your business profile and writes qualified leads
  2. Reddit (OAuth2) Perform Reddit post searches based on generated queries
  3. Google Gemini API Analyse posts, generate queries, and extract insights
  4. Slack API : Notify your team with qualified lead summaries

Google Sheets Setup

You will need two Google Sheets:

  1. Business Profile Sheet (Input) This sheet contains a single row describing your service business. The workflow reads this to generate relevant subreddit selections and search queries.

Required Fields (as headers in row 1):

  • profession

  • industry

  • primary_services

  • service_keywords

  • target_client_profile

  • pain_points

  • intent_signals

  • urgency_indicators

  • price_range

  1. Reddit Leads Sheet (Output) This sheet stores high-quality Reddit posts identified as potential leads. The workflow appends or updates rows based on post_id to avoid duplication.

Expected Columns:

  • post_id

  • post_url

  • post_title

  • post_post

  • post_subreddit

  • post_date

Automated Reddit Lead Generation with AI Analysis and Google Sheets

This n8n workflow automates the process of finding potential leads on Reddit, analyzing their posts using AI, and storing the relevant information in a Google Sheet. It's designed to help businesses identify and track users expressing interest in specific products or services, streamlining lead generation and qualification.

What it does

This workflow performs the following key steps:

  1. Triggers on a Schedule: The workflow starts at predefined intervals (e.g., daily, hourly) to continuously monitor Reddit.
  2. Fetches Reddit Posts: It queries Reddit for posts based on specified keywords or subreddits.
  3. Analyzes Posts with AI: Each Reddit post is passed through a Google Gemini Chat Model and a Text Classifier (via LangChain integration).
    • The Basic LLM Chain likely extracts key information or summarizes the post.
    • The Structured Output Parser then processes this information into a structured format.
    • The Text Classifier categorizes the post, potentially identifying if it's a lead or relevant to a specific topic.
  4. Filters Relevant Leads: Based on the AI analysis, the workflow filters out posts that are not deemed relevant leads.
  5. Stores Data in Google Sheets: For each relevant lead, the workflow adds a new row to a specified Google Sheet, including the extracted information.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • Reddit Account: A Reddit account for setting up API credentials to fetch posts.
  • Google Account: A Google account with access to Google Sheets for storing lead data.
  • Google Gemini API Key: Access to the Google Gemini API for the AI chat model.
  • LangChain Credentials: Proper configuration for LangChain nodes within n8n (which typically involves API keys for the underlying LLMs like Google Gemini).

Setup/Usage

  1. Import the Workflow: Import the provided JSON workflow into your n8n instance.
  2. Configure Credentials:
    • Reddit Node: Set up your Reddit API credentials.
    • Google Sheets Node: Authenticate with your Google account and specify the Spreadsheet ID and Sheet Name where leads should be stored.
    • Google Gemini Chat Model Node: Provide your Google Gemini API key.
    • LangChain Nodes: Ensure all LangChain-related nodes (Basic LLM Chain, Structured Output Parser, Text Classifier) are configured with the necessary API keys and settings for your chosen LLM (Google Gemini in this case).
  3. Customize Reddit Query: In the "Reddit" node, configure the subreddits, keywords, or other search parameters to find relevant posts.
  4. Refine AI Logic: Adjust the prompts and classification rules within the "Basic LLM Chain", "Structured Output Parser", and "Text Classifier" nodes to accurately identify and extract information from your target leads.
  5. Activate the Workflow: Once configured, activate the "Schedule Trigger" node to start the automated lead generation process.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
