Crafting Your Blog Research and Writer n8n Flow: Step-by-Step

Based on the provided workflow, here is a detailed step-by-step process for building a powerful, AI-driven blog creation pipeline in n8n.
For a real-world example you can explore and adapt, check out our n8n AI WordPress Keywords-Based Post Creation workflow, which demonstrates how to turn keyword inputs into fully formatted WordPress drafts automatically.

5.1 User Input & Configuration

The entire process begins with user input, which provides the necessary context for the AI.

• Input Form: The workflow is triggered by a user filling out an n8n Form. This form captures the essential parameters for the article: comma-separated keywords, the desired number of chapters, and a max word count.
• Configuration: A Set node immediately follows the form. It takes the user’s input and stores it in variables for easy access throughout the workflow. This is also where you would configure static settings, like your WordPress site’s URL.

5.2 AI-Powered Article Structuring

With the initial parameters set, the AI takes over to build the article’s skeleton.

• Structure Generation: An OpenAI node is prompted to create a comprehensive structure for the article based on the provided keywords. This isn’t just a simple outline; it generates a JSON object containing the article’s title, subtitle, a ~60-word introduction, ~60-word conclusions, a detailed image prompt for the featured image, and an array of chapters.
• Chapter Prompts: For each chapter, the AI creates a unique `title` and an exhaustive `prompt`. This prompt will guide a separate AI instance in writing the detailed text for that specific section, ensuring a logical flow and preventing repetition. The AI is also connected to a Wikipedia tool to enhance accuracy and depth.
• Data Validation: An If node checks the AI’s output to ensure all required fields (title, chapters, intro, etc.) are present. If any data is missing, the workflow branches to an error message, preventing incomplete articles from being processed.

5.3 Generating Chapter Content

The workflow then iterates through each chapter prompt to write the body of the article.

• Splitting Chapters: A Split Out node takes the array of chapters from the structure and creates a separate execution path for each one, allowing them to be processed individually.
• Writing Each Chapter: Another OpenAI node is used in this loop. For each chapter, it receives the specific `title` and `prompt` generated earlier. It’s instructed to write a detailed section of a specific word count, maintaining coherence with the preceding and following chapters. This ensures the final article reads as a single, unified piece rather than a collection of disconnected parts.

5.4 Assembling the Final Article

Once all chapters are written, they are combined into a single, publishable document.

• Merging Content: A Merge node gathers the written text from each chapter execution.
• Final Assembly: A Code node assembles the full article in HTML format. It starts with the introduction, then iterates through each chapter, adding the chapter title in bold followed by its corresponding text. Finally, it appends the conclusions. The output is a single block of HTML ready for WordPress.

5.5 Generating a Featured Image

To make the article more engaging, a unique featured image is created.

• Image Generation: The workflow uses the `imagePrompt` from the initial structure step to task an OpenAI (DALL·E) node with generating a high-quality, relevant featured image for the post.
• Uploading to WordPress: An HTTP Request node is used to upload the newly generated image to the WordPress media library.

5.6 Publishing to WordPress

The final step is to publish the content and provide feedback to the user.

• Create Draft Post: A WordPress node takes the final assembled article text and the title and creates a new post on your site, saving it as a draft.
• Set Featured Image: Another HTTP Request node updates the newly created post, assigning the uploaded image as its featured image.
• Success Notification: Finally, a Respond to Webhook node sends a success message back to the user’s form, confirming that the article has been created as a draft and providing its title.

A More Complex Showcase Workflow: Data-Driven Content Refresh

To illustrate a more intricate application, let’s consider a workflow designed to identify underperforming blog posts and suggest data-driven rewrites:

1. Google Analytics Trigger (Webhook or Scheduled): This workflow is triggered either by a scheduled interval or by a webhook receiving data from Google Analytics.
2. Fetch Performance Data (Google Analytics Node): Retrieve data for your existing blog posts, focusing on metrics like page views, bounce rate, and average time on page over a specific period.
3. Filter Underperforming Posts (Function Node or Filter Node): Use a Function node or a Filter node to identify posts that fall below certain performance thresholds (e.g., low page views and high bounce rate).
4. Extract Post Content (HTTP Request Node or WordPress Node): For the identified underperforming posts, fetch the current content using an HTTP Request to your website or directly via the WordPress node.
5. Keyword Analysis (OpenAI or Google Gemini Node): Analyze the content to identify the primary and secondary keywords.
6. Competitive Analysis (Google Custom Search & Scraping Nodes): Perform a new search for the primary keyword and scrape the top-ranking articles to identify updated information, new angles, and content gaps.
7. Rewrite Suggestions (OpenAI or Google Gemini Node): Provide the original content, the keyword analysis, and the competitive analysis to an LLM. Instruct it to suggest specific rewrites to improve the content’s comprehensiveness, accuracy, and engagement, potentially suggesting new sections, updated information, or better keyword integration.
8. Generate HTML Report (HTML Report Node): Create a visually appealing HTML report summarizing the performance data, highlighting the identified issues, and presenting the suggested rewrites.
9. Send Report for Review (Email or Slack Node): Send the HTML report to content editors for review and implementation of the suggested changes.
10. Update Tracking Sheet (Google Sheets Node): Record that a rewrite suggestion has been generated for the specific post.

Technical & Operational Considerations

Building and maintaining these automated workflows requires careful consideration of several technical and operational aspects:

• API Keys and Credentials: You’ll need API keys for various services like OpenAI, Perplexity, Google Custom Search, and credentials for accessing your WordPress site, Notion, and Google Sheets. Ensure these are securely managed within n8n’s credentials management system.
• Runtime Setup: Decide whether to run n8n self-hosted or on n8n Cloud. For persistent automation, self-hosting often involves using Docker or PM2 to ensure your n8n instance runs reliably in the background. n8n Cloud offers a managed solution, simplifying the setup and maintenance.
• Cost Estimates: Be mindful of the costs associated with the services you integrate. This includes token usage for LLMs, credits for image generation services, and potential costs for storage services like Apify or cloud databases. Monitor your usage to avoid unexpected expenses.
• Handling Revisions and Quality Control: Implement robust approval flows and feedback mechanisms to ensure the quality of the automated content. Consider versioning your n8n workflows to track changes and easily revert to previous versions if needed.
