Enterprise Reddit Intelligence and ML Lead Generation - n8n Workflow

• Lead Generation Specialists needing to tap into high-intent social conversations.
• Marketing Operations teams requiring high-volume, compliant social engagement.
• Technical founders looking for complex n8n templates integrating multiple AI and CRM APIs.
• Data scientists aiming to use n8n for ML model prediction and feedback loops.

The Enterprise Reddit Intelligence Platform is a sophisticated solution built using n8n to manage high-volume community engagement and competitive intelligence across 20+ subreddits daily. Traditional monitoring is inefficient, but this n8n workflow leverages multi-stage AI (sentiment, intent, relevance scoring) and Machine Learning (ML) to score every post. By using this powerful n8n workflow, organizations can efficiently identify 'Hot Leads,' generate tailored responses (including competitive counter-responses), and ensure every outbound comment passes a strict Quality Assurance Gate.

This robust n8n workflow guarantees that only relevant, high-potential posts are engaged with, preventing duplicate interactions and maximizing conversion rates, while feeding engagement data back to the ML model for continuous optimization.

This complex n8n workflow initiates execution via one of three possible n8n trigger nodes: the 'Schedule Trigger' (running every 3 hours), the 'Webhook Trigger,' or the 'Manual Trigger.'

1. Configuration & Search: The n8n workflow merges triggers and immediately loads the target subreddit list from an external configuration API. The 'Split Subreddits' n8n node processes these batches, sending items to parallel 'Reddit' n8n node searches (one for general posts, one for competitor mentions).


2. Filtering & Deduplication: The combined results are passed to an HTTP Request n8n node ('Check Engagement History') to prevent duplicate responses. The 'Filter New Posts' If n8n node only proceeds with new, unengaged posts.


3. Multi-Stage AI Analysis: The post data moves through a sophisticated three-stage analysis pipeline, executed by three separate HTTP Request n8n node calls to external AI APIs. This determines sentiment, lead potential, relevance, and strategic assessment.


4. ML Prediction & Routing: The n8n workflow retrieves historical performance data and runs an 'ML Prediction' via an HTTP Request n8n node to assign an overall engagementScore. The 'Route by Priority' Switch n8n node directs flow based on this score and content (e.g., competitor mentions trigger 'Generate Competitive' response).


5. Response Generation & Testing: Different response types are generated by specific AI API calls. For premium leads, the 'Select Variant' Code n8n node performs A/B testing, randomly choosing between generated response variants.


6. Quality Gate & Action: All generated responses are merged and subjected to the 'Quality Check' Code n8n node, which looks for promotional language and length issues. The 'Quality Gate' If n8n node prevents non-compliant comments from proceeding. After a 60-second 'Rate Limit' Wait n8n node, the 'Post Comment' Reddit n8n node executes the action.


7. Lead Pipeline: If a post is identified as a high-potential lead, the n8n workflow enriches the lead data, calculates a final 'leadScore' (using a Code n8n node for bonus points based on enrichment), and routes the lead using the 'Route Lead' Switch n8n node into appropriate CRM funnels (Hot, Warm, Cold) via multiple HTTP Request n8n node calls, including Slack alerts for 'Hot Leads.'


8. Logging: The final step ensures all engagement data is logged for analytics and used to 'Update ML' models, closing the optimization loop of this complex n8n workflow.

1. Import the n8n workflow: Copy the provided JSON code and import it into your n8n instance using the 'New' -> 'Import from JSON' option.


2. Set Credentials: You must configure credentials for the Reddit n8n node (OAuth2) to allow searching and posting comments.


3. Configure Environment Variables: This n8n workflow relies heavily on external custom APIs. You must set the following environment variables (or replace the expressions in the HTTP Request n8n node parameters):

1. Activate: Ensure your credentials are set and the necessary external APIs are accessible. Enable the n8n trigger nodes (Schedule, Webhook) to start the automation.

Schedule Trigger / Webhook Trigger / Manual Trigger: These n8n trigger nodes initiate the complex n8n workflow, allowing for scheduled monitoring, external invocation, or manual testing.
Load Subreddit Config (HTTP Request n8n node): Fetches the dynamic list of target subreddits from an external database API ({{$env.DBAPIURL}}/config/subreddits).
Search Posts / Search Competitor Mentions (Reddit n8n node): The core data gathering nodes. They use expressions like ={{$json.subreddit}} to iterate and search based on the loaded configuration, setting limits to 30 posts.
Check Engagement History (HTTP Request n8n node): Sends postId and author data to the external database to determine if the n8n workflow has previously interacted with this thread.
AI Stage 1, 2, & 3 (HTTP Request n8n nodes): Executes the three-stage AI analysis pipeline, chaining analysis results from one stage into the next to refine insights, crucial for the intelligence of this n8n workflow.
ML Prediction (HTTP Request n8n node): Consolidates all AI analysis and historical data to predict the optimal engagementScore for the post.
Route by Priority (Switch n8n node): A critical flow control n8n node that directs the automation based on derived properties like engagementScore and hasCompetitorMention, ensuring the correct response generation path is taken.
Select Variant (Code n8n node): Implements A/B testing by randomly selecting 'A' or 'B' variants of the premium response generated by the AI, allowing the n8n workflow to track performance.
Quality Check (Code n8n node): Performs rule-based validation on the AI-generated response (checking for banned keywords, promotional language, and length) before proceeding to the actual post action.
Post Comment (Reddit n8n node): Executes the final, compliant action on Reddit, using the generated text (={{$json.response}}).
Enrich Lead (HTTP Request n8n node): Gathers external data (e.g., company info, LinkedIn profile) for high-potential leads.
Score Lead (Code n8n node): Calculates the final enriched lead score, applying bonus points for validated data, defining the lead tier (hot/warm/cold).

• Route Lead (Switch n8n node): Routes the scored lead to the correct CRM integration endpoints (/leads/hot, /leads/warm, /leads/cold) for nurture sequences.
