What Is a Cached Page?
A cached page is a copy of a web page that a web server or search engine stores to make accessing and retrieving this page easy in the future.
The page is cached to quicken the process when the same information (available on that particular page) is requested in the future and reduces the server load.
When the pages of a website are crawled and indexed by a search engine, a copy of the crawled and indexed web page is cached (or stored) in the temporary storage location. This copy is then used to display the information available on it when a user searches for this information.
When you see a webpage listed in Google search results, there is usually a "Cached" link that you can click to view the version of the page that Google last captured.
