Definition - What does Archive Site mean?
An archive site is a website that presents obsolete or dead webpages for a viewing audience. This is part of keeping alive the “retro tech” phenomenon, and maintaining old technology landmarks for posterity.
Techopedia explains Archive Site
Archive sites may work on the basis of a web crawler to look for specific kinds of obsolete content, or they may work on the basis of user submissions. Some work on a combination of the two. Other archive websites might pull from a specific venue. For instance, the massive GeoCities web domain that was taken down years ago was a repository for many thousands of user-created sites. A GeoCities-specific archive site might take various pages from this obsolete domain, and move them to a place where web users can continue to access them.
