A LIP page, also known as a “lost page within the pagination,” is a specific page, such as a product page, that is only linked to other internal pagination pages. In practical terms, it’s a product page whose only links pointing to it originate from pagination pages, starting from page 2 or beyond. This concept was introduced by SEO experts Olivier Duffez and Fabien Faceries. The existence of a LIP page significantly reduces a visitor’s chances of finding the product on an e-commerce website.
