Cobweb site is a slang term that refers to a website that has not been updated for a long period of time despite still being accessible over the Internet. A website may become a cobweb site for a short period while the creator is pursuing other interests or it may be a truly forgotten part of the Web. Cobweb sites can actually become quite highly ranked in searches for timeless content, but searches for timely content usually have a freshness factor that filters out cobweb sites.
