The term "single site" refers to a website that has only one page or a single point of entry. This type of website is designed in such a way that all content and information are displayed on a single page, with navigation links allowing visitors to easily move between different sections of the site without having to click through multiple pages. Single sites can be an effective option for businesses or organizations looking to establish an online presence quickly and efficiently, as they require less time and resources to design and build compared to multi-page websites.
