Auto import periodically checks the specified Listing URL and automatically imports new products to your website. Products are checked by URL. Pagination doesn't apply.
Bear in mind that only new products are imported when selecting a listing URL. For example, you can use a listing URL where products are sorted by the date they were added to the store. So new products will display at the top of the list.
Not all parsers support extracting products from listing pages. It's recommended to test the URL and your import settings on a manual product import page.
