Update Rank Math SEO Metadata via n8n HTTP Request

What This Workflow Does

This workflow updates SEO metadata for WooCommerce products using Rank Math SEO plugin automatically.
It stops the need to do manual work on titles, descriptions, and canonical URLs for each product.
The result is faster product updates and better search engine rankings.

The workflow takes your WooCommerce base URL, sends an API request to Rank Math to update SEO fields, and handles authentication securely.
It also notices if the update fails and tries again to make sure the changes go through.

Inputs, Processing Steps, and Output

Inputs

• WooCommerce base URL: Used to target the API correctly.
• Product post ID and SEO metadata: such as title, description, and canonical URL sent in API request.
• WordPress API credentials: for WordPress and WooCommerce authentication.

Processing Steps

• The workflow starts with the Manual Trigger node.
• A Set node holds the WooCommerce base URL for dynamic use.
• An HTTP Request node sends a POST request to Rank Math’s update-meta API endpoint.
• The HTTP request includes SEO fields like post_id, rank_math_title, rank_math_description, and rank_math_canonical_url.
• The HTTP request uses saved WordPress credentials for authentication.
• If the request fails, retries happen automatically.

Output

Updated SEO metadata on the WooCommerce product page.
Immediate feedback on update success or failure.
