You can individually add a new URL to an existing product, as shown below.
Simply click the 'Add URL' button and keep the following in mind:
The URL should lead to a specific product page with visible price information.
Search or listing pages don't qualify, even if they show price information.
Each URL can be added only once to the panel.
Enter the final destination URL. Avoid redirect links as they may cause issues.
For adding new URLs in bulk, please read this article.
You can always contact our support team if you have any questions or are unsure whether a URL qualifies.
