Full Transcript

When a user visits a product page, the website checks if the product is in stock. If it is, the product page with buying options is shown. If not, an out-of-stock page appears, often with suggestions for similar products or backorder options. This approach helps keep users engaged and can improve search engine optimization by providing useful content even when items are unavailable.
