This workflow is designed to automate the generation and updating of SEO meta titles and descriptions for WooCommerce products using n8n. It leverages Google Sheets for data input, a FREE language model (Gemini 2.0 Flash Exp. via OpenRouter) for generating SEO-optimized meta tags, and WooCommerce for updating product details.

How It Works:

  1. Trigger: The workflow can be triggered manually or on a schedule. The manual trigger allows for testing, while the schedule trigger can be set to run at regular intervals (e.g., every few minutes) to process new products.

  2. Data Retrieval:

    • The workflow starts by retrieving product IDs from a Google Sheets document. It looks for products that do not yet have meta titles or descriptions.
    • Using the retrieved product ID, the workflow fetches the corresponding product details from WooCommerce, including the product name, description, short description, and categories.

  3. Meta Tag Generation:

    • The product details are passed to a language model (Gemini 2.0 Flash Exp) via OpenRouter. The model generates SEO-optimized meta titles and descriptions based on the provided content.
    • The generated meta tags are structured and validated to ensure they meet SEO best practices, such as character limits and keyword inclusion.

  4. Update WooCommerce:

    • The generated meta title and description are then updated in the WooCommerce product metadata using the Yoast SEO fields.

  5. Update Google Sheets:

    • Finally, the workflow updates the Google Sheets document with the newly generated meta tags, along with the product URL, title, and the timestamp of the update.

Set Up Steps:

  1. Google Sheets Setup:

    • Create a copy of the provided Google Sheets template and insert WooCommerce product IDs in column "B".
    • Ensure the Google Sheets document has columns for METATITLE, METADESCRIPTION, URL, TITLE POST, and DATA (timestamp).

  2. n8n Workflow Configuration:

    • Google Sheets Node: Configure the "Get product ID" node to connect to your Google Sheets document. Use OAuth2 for authentication.
    • WooCommerce Node: Set up the WooCommerce nodes to connect to your WooCommerce store using the WooCommerce API credentials.
    • OpenRouter Node: Configure the "Gemini 2.0 Flash Exp" node with your OpenRouter API credentials to access the language model.
    • Structured Output Parser: Ensure the output parser is set to handle the structured data format for meta titles and descriptions.

  3. Workflow Execution:

    • Trigger the workflow manually to test the process or set up a schedule trigger to automate the workflow at regular intervals.
    • Monitor the workflow execution to ensure that meta tags are generated and updated correctly in both WooCommerce and Google Sheets.

  4. Validation:

    • After the workflow runs, verify that the meta titles and descriptions in WooCommerce are correctly updated and that the Google Sheets document reflects the changes.

This workflow streamlines the process of optimizing WooCommerce product pages for SEO, saving time and ensuring consistency in meta tag generation.

Automate WooCommerce SEO with AI-Powered Meta Tag Generation

This n8n workflow automates the process of generating and updating SEO meta descriptions and keywords for your WooCommerce products using AI, drawing product data from a Google Sheet. It helps streamline your e-commerce SEO efforts, ensuring your products have optimized meta tags without manual intervention.

What it does

This workflow performs the following key steps:

  1. Triggers Manually or on Schedule: The workflow can be executed manually or set to run at scheduled intervals to periodically update your product SEO.
  2. Fetches Product Data from Google Sheets: It reads product information (e.g., product name, description) from a specified Google Sheet, which serves as the source of truth for your product catalog.
  3. Generates SEO Meta Tags with AI:
    • It uses a Basic LLM Chain to send the product data to an OpenRouter Chat Model (an AI language model).
    • The AI is prompted to generate an SEO-optimized meta description and a list of relevant keywords for each product.
  4. Parses AI Output: A Structured Output Parser extracts the generated meta description and keywords from the AI's response in a structured format.
  5. Updates WooCommerce Products: Finally, it takes the AI-generated meta description and keywords and updates the corresponding product's SEO fields in WooCommerce.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Google Sheets Account: With a spreadsheet containing your WooCommerce product data.
  • WooCommerce Store: An active WooCommerce store with API access enabled.
  • OpenRouter API Key: An API key for OpenRouter to access their AI chat models.
  • n8n Credentials: Configured credentials for Google Sheets, WooCommerce, and OpenRouter within your n8n instance.

Setup/Usage

  1. Import the Workflow:
    • Download the provided JSON file.
    • In your n8n instance, go to "Workflows" and click "New".
    • Click the "Import from JSON" button and paste the workflow JSON or upload the file.
  2. Configure Credentials:
    • Locate the "Google Sheets" node and configure your Google Sheets credentials.
    • Locate the "WooCommerce" node and configure your WooCommerce API credentials (Consumer Key and Consumer Secret).
    • Locate the "OpenRouter Chat Model" node and configure your OpenRouter API key.
  3. Specify Google Sheet Details:
    • In the "Google Sheets" node, specify the "Spreadsheet ID" and "Sheet Name" where your product data is located. Ensure your sheet has columns for product names and descriptions that the AI can use.
  4. Customize AI Prompt (Optional):
    • In the "Basic LLM Chain" node, you can review and modify the prompt sent to the AI to fine-tune the meta tag generation according to your specific SEO strategy.
  5. Configure WooCommerce Update:
    • In the "WooCommerce" node, ensure the operation is set to "Update Product" and map the incoming AI-generated meta description and keywords to the appropriate WooCommerce product fields (e.g., meta_description, yoast_seo_keywords if using Yoast SEO plugin). You will need to ensure a unique identifier (like product ID or SKU) is passed from Google Sheets to match products.
  6. Run the Workflow:
    • You can execute the workflow manually by clicking "Execute Workflow" on the "When clicking ‘Execute workflow’" node.
    • To automate, enable the "Schedule Trigger" node and configure its schedule (e.g., daily, weekly) to run the workflow automatically.

Prerequisites TenderNed API Access - Register at TenderNed for API credentials Configuration Steps Set up TenderNed credentials: Add HTTP Basic Auth credentials with your TenderNed API username and password Apply these credentials to the three HTTP Request nodes: "Tenderned Publicaties" "Haal XML Details" "Haal JSON Details" Customize filters: Modify the "Filter op ..." node to match your specific requirements Examples: specific organizations, contract values, regions, etc. How It Works Step 1: Trigger The workflow can be triggered either manually for testing or automatically on a daily schedule. Step 2: Fetch Publications Makes an API call to TenderNed to retrieve a list of recent publications (up to 100 per request). Step 3: Process & Split Extracts the tender array from the response and splits it into individual items for processing. Step 4: Fetch Details For each tender, the workflow makes two parallel API calls: XML endpoint - Retrieves the complete tender documentation in XML format JSON endpoint - Fetches metadata including reference numbers and keywords Step 5: Parse & Merge Parses the XML data and merges it with the JSON metadata and batch information into a single data structure. Step 6: Extract Fields Maps the raw API data to clean, structured fields including: Publication ID and date Organization name Tender title and description Reference numbers (kenmerk, TED number) Step 7: Filter Applies your custom filter criteria to focus on relevant tenders only.
