The principle of front doors emphasizes that not all users will start their journey on your homepage. Regardless of which page they land on, users should be able to find what they need quickly and easily. This means every page should serve as a helpful entry point, guiding users to the main areas of your site. For example, consider an e-commerce website. A user might land directly on a product page from a search engine. This page should provide clear navigation options to other parts of the site, such as categories, related products, and customer support. This way, even if the product they originally searched for isn't suitable, they can still easily explore and find alternatives.
