Bulk WordPress SEO Meta Optimizer with Rank Math & AI

This n8n workflow, along with its companion WordPress plugin (rank_math_tools.zip), automates the bulk optimization of your WordPress posts' Rank Math SEO titles and descriptions using AI.

Stop manually crafting metas and let AI supercharge your SEO efforts efficiently!

free version here.

How it works:

This workflow streamlines your SEO process through several automated steps:

  • Fetches Post IDs: Retrieves all published post IDs from your WordPress site using a secure, custom API endpoint provided by the companion plugin.
  • Gathers Post Content: For each identified post, it accesses the existing title, slug, and main rendered content to provide context for the AI.
  • AI-Powered Meta Generation: Leverages an AI model of your choice via OpenRouter (defaulting to Claude 3.7 Sonnet) to generate an optimized SEO title and meta description. This generation is guided by a detailed, customizable prompt within the "Create Meta Infos" node, allowing you to define the style, tone, and SEO strategy.
  • Updates WordPress Metas: Sends the newly generated SEO title and description back to your WordPress site via another custom API endpoint. The companion plugin then updates the specific Rank Math fields for each post.
  • Refreshes Modified Date: The companion plugin automatically updates the post's 'last modified' date in WordPress whenever meta information is changed, which can be a positive signal for search engines.
  • Selective Processing: An "IF" node ("Should I Rewrite") intelligently determines whether a post's metas need updating based on predefined conditions (e.g., empty metas or placeholder content), optimizing resource usage.

Setup Steps:

Get up and running in approximately 15-25 minutes by following these high-level steps. Detailed instructions are available in the comprehensive documentation provided with your purchase and within the sticky notes inside the n8n workflow itself.

  1. Install the Companion WordPress Plugin:
    • Download the rank_math_tools.zip file.
    • Upload and activate it on your WordPress site.
    • (Estimated time: 2-5 minutes)
  2. Configure WordPress API Authentication:
    • In your WordPress admin area, go to your user profile and create a new Application Password.
    • Ensure the user has at least an "Editor" role.
    • Copy the generated password.
    • (Estimated time: 2-5 minutes)
  3. Set Up n8n Credentials:
    • In n8n, create a new "WordPress API" credential using your WordPress username, the Application Password you just copied, and your site's Base URL.
    • Create a new "OpenRouter Api" credential using your OpenRouter API key.
    • (Estimated time: 5-10 minutes, assuming you have your OpenRouter key ready)
  4. Import and Configure the n8n Workflow:
    • Download the Bulk_Wordpress_Meta_Data_Optimizer_Gumroad.json workflow file.
    • Import it into your n8n instance.
    • Link your newly created WordPress and OpenRouter credentials to the respective nodes in the workflow.
    • Verify and update your WordPress site URL in the "settings" node (ensure it has a trailing slash /).
    • Review the "Limit" node – it's pre-set to process only 5 items for safe initial testing.
    • (Estimated time: 5-10 minutes)

Benefits:

  • Full SEO Meta Automation: Drastically reduce manual effort by automatically generating and updating SEO titles and descriptions for all your posts.
  • Bulk Processing Power: Efficiently handle meta optimization for hundreds or thousands of WordPress posts.
  • Highly Customizable AI Output: Fine-tune the AI's generation style, keyword focus, and direct response techniques by editing the detailed prompt within the "Create Meta Infos" node.
  • Improved SEO Consistency & Quality: Ensure all your articles have relevant, compelling, and optimized meta tags, adhering to best practices.
  • Signal Freshness to Search Engines: The automatic update of the post 'last modified' date upon meta change can help improve crawl frequency and SEO.
  • Resource-Efficient Updates: The "Should I Rewrite" node prevents unnecessary processing and API calls for posts that already have satisfactory meta information.
  • Save Time & Focus on Content: Free up valuable time to concentrate on creating great content, rather than on repetitive SEO tasks.

To understand exactly how to use and customize this workflow in detail, please refer to the comprehensive step-by-step documentation provided with your purchase.

WordPress Rank Math Bulk Title & Description Optimizer

This n8n workflow automates the process of generating and updating SEO titles and descriptions for WordPress posts using AI, specifically tailored for Rank Math SEO. It fetches a list of posts, generates optimized meta information, and then updates the posts in batches.

Description

This workflow streamlines the SEO optimization of WordPress content. It leverages AI to create engaging and keyword-rich titles and descriptions for your posts, then automatically applies these changes to your WordPress site through the Rank Math API. This is particularly useful for bulk optimizing existing content to improve search engine visibility without manual effort for each post.

What it does

  1. Manually Trigger: The workflow is initiated manually, allowing you to control when the optimization process begins.
  2. Fetch WordPress Posts: It retrieves a specified number of WordPress posts (defaulting to 100).
  3. Limit Posts (Optional): An optional step to limit the number of posts processed, useful for testing or incremental updates.
  4. Loop Over Posts: Each fetched post is processed individually in batches.
  5. Prepare Data for AI: For each post, it extracts relevant information like the post title and content, and constructs a prompt for the AI model.
  6. Generate SEO Meta with AI: It uses an AI chat model (OpenRouter) and a structured output parser to generate an optimized SEO title and description based on the post's content and existing title.
  7. Conditional Update Check: It checks if the AI successfully generated both a title and a description.
  8. Update WordPress Post (If Valid): If both an SEO title and description are generated, the workflow updates the corresponding WordPress post with the new Rank Math SEO title and description.
  9. No Operation (If Invalid): If the AI fails to generate both, the post is skipped without updating.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance.
  • WordPress Account: Access to a WordPress site with the Rank Math SEO plugin installed and configured.
  • WordPress Credential: An n8n credential configured for your WordPress site (API access required).
  • OpenRouter API Key: An API key for OpenRouter (or another compatible AI chat model configured within the "OpenRouter Chat Model" node).
  • LangChain Nodes: Ensure you have the @n8n/n8n-nodes-langchain package installed in your n8n instance.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure WordPress Credential:
    • Locate the "Wordpress" node.
    • Click on "Credentials" and select or create a new WordPress API credential.
    • Provide your WordPress URL, username, and application password (generated in WordPress under Users > Profile > Application Passwords).
  3. Configure OpenRouter API Key:
    • Locate the "OpenRouter Chat Model" node.
    • Click on "Credentials" and select or create a new OpenRouter API credential.
    • Enter your OpenRouter API key.
  4. Review and Adjust (Optional):
    • "HTTP Request" (Fetch Posts): You can adjust the per_page parameter in the URL to fetch more or fewer posts.
    • "Limit" Node: Modify the "Limit" node if you only want to process a specific number of posts (e.g., for testing).
    • "Edit Fields" (Set): Review the prompt for the AI model to ensure it meets your SEO requirements. You might want to fine-tune the instructions given to the AI.
    • "Loop Over Items": The batch size can be adjusted here.
  5. Execute the Workflow: Click the "Execute Workflow" button to start the optimization process.

Important Notes:

  • It is highly recommended to test this workflow on a staging environment or with a small number of posts first to ensure the generated content meets your quality standards before running it on your live site with many posts.
  • The AI's output quality depends heavily on the prompt provided in the "Edit Fields" node and the capabilities of the chosen LLM. You may need to experiment with the prompt to get the best results for your specific content.
  • The workflow is designed to update Rank Math SEO titles and descriptions. If you are using a different SEO plugin, this workflow might not be directly compatible without modifications.
