To copy a product link from Alibaba to your store, follow these steps:

1. Open the Alibaba website and find the product you want to copy the link to.

2. Select the product you want to copy the link to, right-click it, and select "Copy Link Address" from the pop-up menu.

3. Your computer has now copied the link to the product.

4. Open your store website or store backend management system and enter the product release page.

5. Paste the link you copied on Alibaba into the "Add New Product" or "Upload New Product" input box.

6. Click "OK" or "Next" to start editing the product information. You can add pictures, product descriptions, prices, inventory and other information.

7. After editing, save and publish your product.

8. When the product is successfully published, you can view your product on your store page and sell it.

Note: You need to make sure that your store backend management system supports copying product links from Alibaba and can automatically identify and fill in product information. Some older backend management systems may not support this function. If you are using a new store management system, there are usually easier ways to add new products, such as copying products with one click, automatically filling in product information, etc.
