Hello, I apologize for the issue you’re facing with double meta descriptions on your product pages. I understand that the short description of the product in WooCommerce is also being parsed as the meta description.
To solve this issue, you can follow these steps:
- Navigate to your WordPress Dashboard and go to Rank Math SEO > Titles & Meta > Products.
- Scroll down to the Single Product Description field and enter a description that you want to use as the meta description for your products. This will override the short description being parsed as the meta description.
- Click on Save Changes to save your settings.
Here’s an example screenshot of where you can enter the single product description:

By setting a single product description, Rank Math will use it as the meta description when the product short description is unavailable.
