Who is this workflow for? Efficiently manage and update your WordPress and WooCommerce SEO metadata with this n8n workflow. By leveraging a custom WordPress plugin that extends the REST API, this workflow automates the updating of Rank Math SEO fields—SEO Title, Description, and Canonical URL—for your posts and products..

What does this workflow do?

  • Trigger Setup:
  • The workflow begins with a webhook or schedule trigger in n8n, determining when the SEO update should occur.
  • Retrieve Target Content:
  • Specify the post or product ID that needs its SEO fields updated. This can be dynamically sourced from a datastore like Google Sheets or GitHub.
  • HTTP Request to Custom API:
  • An HTTP Request node sends a POST request to the custom API endpoint (rank-math-api/v1/update-meta) provided by the Rank Math API Manager Extended plugin.
  • Update SEO Metadata:
  • The API processes the request, updating the SEO Title, Description, and Canonical URL for the specified content.
  • Confirmation and Logging:
  • The workflow receives a response indicating the success or failure of each metadata update. This information can be logged to platforms like Google Sheets or sent via WhatsApp for notifications.
  • Error Handling:
  • Implement error handling to manage any issues during the update process, ensuring reliability and consistency.
  • Install the Plugin:
  • Add the above PHP code as a new plugin in your WordPress installation.
  • Activate the plugin through the WordPress admin dashboard.
  • Configure the Workflow in n8n:
  • Webhook Node: Set up a trigger for when the SEO update should occur.
  • HTTP Request Node: Configure it to send a POST request to https://yourwordpresssite.com/wp-json/rank-math-api/v1/update-meta with the required parameters (post_id, rank_math_title, rank_math_description, rank_math_canonical_url).
  • Additional Nodes: Integrate with tools like Google Sheets or WhatsApp for logging and notifications as needed.
  • Run the Workflow:
  • Initiate the workflow manually or set it to trigger automatically based on your configuration.
  • The specified SEO fields will be updated for the targeted post or product.

By following these steps, you can automate and manage your SEO metadata efficiently, ensuring your WordPress site and WooCommerce products are always optimized.
