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

How it works

This advanced automation builds a fully autonomous SEO blog writer using n8n, Scrapeless, LLMs, and Pinecone vector database. It’s powered by a Retrieval-Augmented Generation (RAG) system that collects high-performing blog content, stores it in a vector store, and then generates new blog posts based on that knowledge—endlessly.

Part 1: Build a Knowledge Base from Popular Blogs

  • Scrape existing articles from a well-established writer (in this case, Mark Manson) using the Scrapeless node.
  • Extract content from blog pages and store it in Pinecone, a powerful vector database that supports similarity search.
  • Use Gemini Embedding 001 or any other supported embedding model to encode blog content into vectors.
  • Result: You’ll have a searchable vector store of expert-level content, ready to be used for content generation and intelligent search.

Part 2: SERP Analysis & AI Blog Generation

  • Use Scrapeless' SERP node to fetch search results based on your keyword and search intent.
  • Send the results to an LLM (like Gemini, OpenRouter, or OpenAI) to generate a keyword analysis report in Markdown → then converted to HTML.
  • Extract long-tail keywords, search intent insights, and content angles from this report.
  • Feed everything into another LLM with access to your Pinecone-stored knowledge base, and generate a fully SEO-optimized blog post.

Set up steps

Generate SEO-Optimized Blog Content with Gemini, Scrapeless, and Pinecone RAG

This n8n workflow automates the process of generating SEO-optimized blog content by leveraging AI, web scraping, and a vector database for Retrieval Augmented Generation (RAG). It allows you to provide a blog topic, scrape relevant content from the web, store it in Pinecone, and then use Google Gemini to generate a comprehensive blog post based on the retrieved information.

What it does

  1. Triggers Manually: The workflow starts when manually executed, prompting for a blog topic.
  2. Sets Initial Data: Defines the blog topic and a URL for web scraping.
  3. Scrapes Web Content: Uses a "Scrapeless" tool (via the AI Agent) to extract content from the specified URL.
  4. Processes Scraped Data:
    • Converts the scraped HTML content into a file.
    • Splits the content into smaller, manageable chunks using a Recursive Character Text Splitter.
    • Aggregates the split text chunks.
  5. Generates Embeddings: Creates vector embeddings for the processed text using Google Gemini's embedding model.
  6. Stores in Pinecone: Stores the generated embeddings in a Pinecone vector store, making them searchable.
  7. Retrieves Relevant Information: Uses the AI Agent to query the Pinecone vector store for information relevant to the blog topic.
  8. Generates Blog Content: Employs a Basic LLM Chain with the Google Gemini Chat Model to generate a comprehensive blog post based on the retrieved information and the initial blog topic.
  9. Formats Output: Presents the final blog content in Markdown format.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance.
  • Google Gemini API Key: For text embeddings and chat model.
  • Pinecone API Key and Environment: For the vector database.
  • Scrapeless API Key: For web scraping capabilities (used by the AI Agent).
  • Langchain Credentials: Ensure your n8n instance has the necessary Langchain credentials configured for Google Gemini, Pinecone, and any other AI/tool integrations.

Setup/Usage

  1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Locate the "Embeddings Google Gemini" node and configure your Google Gemini API key.
    • Locate the "Google Gemini Chat Model" node and configure your Google Gemini API key.
    • Locate the "Pinecone Vector Store" node and configure your Pinecone API Key and Environment.
    • If the "AI Agent" node requires specific tool credentials (e.g., for Scrapeless), ensure they are configured within the Langchain tool settings.
  3. Set Initial Parameters:
    • In the "Edit Fields" node, update the blogTopic and urlToScrape values to match your desired blog topic and the URL you wish to scrape for content.
  4. Execute the Workflow: Click "Execute Workflow" on the "When clicking ‘Execute workflow’" node to start the content generation process.
  5. Review Output: The final generated blog content will be available in the "Markdown" node.

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.
