# Automate SEO Blog Creation & Social Media with GPT-4, Perplexity, and WordPress

This n8n workflow automates the entire process of generating SEO-optimized blog posts using AI, publishing them to WordPress, and then promoting them across social media platforms like Facebook and X (formerly Twitter). It leverages advanced AI models like GPT-4 and Perplexity (via an HTTP Request) to create high-quality, engaging content, and integrates with various services to streamline your content marketing efforts.

## What it does

This workflow simplifies content creation and distribution by performing the following steps:

1.  **Triggers Manually or on Schedule**: The workflow can be initiated manually or set to run on a defined schedule.
2.  **Generates Blog Post Ideas**: It uses an AI Agent (likely GPT-4) to brainstorm and generate a list of SEO-friendly blog post titles based on a given prompt or input.
3.  **Fetches Content with Perplexity**: For each generated title, it uses an HTTP Request node to query Perplexity AI, gathering relevant information and content for the blog post.
4.  **Generates Full Blog Content**: Another AI Agent (GPT-4) then takes the gathered information and the blog title to write a comprehensive, SEO-optimized blog post in Markdown format.
5.  **Formats Content for WordPress**: The Markdown content is converted into a suitable format for WordPress.
6.  **Publishes to WordPress**: The generated blog post is automatically published to your WordPress site.
7.  **Generates Social Media Posts**: It uses an AI Agent to create engaging social media updates for Facebook and X (formerly Twitter) based on the newly published blog post.
8.  **Posts to Facebook**: The generated Facebook post is published to your Facebook page via the Facebook Graph API.
9.  **Posts to X (formerly Twitter)**: The generated X (formerly Twitter) post is published to your Twitter account.
10. **Optional Notification**: An optional Gmail node is included, potentially for sending notifications about the successful publication or for human-in-the-loop approvals.
11. **Notion Integration**: An optional Notion node is included, which could be used for tracking content ideas, published posts, or managing the content pipeline.

## Prerequisites/Requirements

To use this workflow, you will need:

*   **n8n Instance**: A running n8n instance.
*   **OpenAI API Key**: For the AI Agent (GPT-4) and OpenAI Chat Model nodes.
*   **Perplexity API Access**: The HTTP Request node will need to be configured to interact with the Perplexity AI API.
*   **WordPress Account**: Credentials for your WordPress site to publish posts.
*   **Facebook Developer Account / Page Access Token**: To post to a Facebook page.
*   **X (formerly Twitter) Developer Account / API Keys**: To post to X (formerly Twitter).
*   **Gmail Account (Optional)**: If you intend to use the Gmail notification feature.
*   **Notion Integration (Optional)**: If you plan to use Notion for content tracking.
*   **Google Sheets (Optional)**: The initial Google Sheets node suggests that content ideas or other data might be pulled from a spreadsheet.

## Setup/Usage

1.  **Import the Workflow**: Download the JSON provided and import it into your n8n instance.
2.  **Configure Credentials**:
    *   Set up your **OpenAI** credentials for the "OpenAI Chat Model" and "OpenAI" nodes.
    *   Configure your **WordPress** credentials.
    *   Set up your **Facebook Graph API** credentials.
    *   Set up your **X (formerly Twitter)** credentials.
    *   (Optional) Configure your **Gmail** and **Notion** credentials if you plan to use these features.
3.  **Customize Perplexity HTTP Request**: Configure the "HTTP Request" node (likely named "Perplexity API Call") with your Perplexity API endpoint and any necessary authentication.
4.  **Adjust AI Prompts**: Review the "AI Agent" and "Basic LLM Chain" nodes to customize the prompts for blog title generation, content creation, and social media post generation to match your specific SEO and content style guidelines.
5.  **Configure WordPress Node**: Ensure the "WordPress" node is set to create new posts and map the generated content fields correctly.
6.  **Configure Social Media Nodes**: Map the generated social media content to the "Facebook Graph API" and "X" nodes.
7.  **(Optional) Configure Google Sheets**: If you want to pull initial blog ideas from Google Sheets, configure the "Google Sheets" node.
8.  **Activate and Test**: Set the workflow to active and run a test execution to ensure all steps are working as expected. You can use the "Manual Trigger" for initial testing.
9.  **Schedule (Optional)**: If you want automated execution, configure the "Schedule Trigger" node to run at your desired intervals.
