One way to view cached versions of Web pages is to follow the link provided in the search results. Another option is to search for cached copies at the Internet Archives website.
When a search for a Web page is conducted via a search engine such as Google, the link that most closely matches the search word or phrase is listed. If a cached copy of the Web page exists, a link is provided under the result link. It is labeled something similar to "cached copy." Clicking that link takes the user to a previous version of that page.
Another option is to use the Wayback Machine on the Internet Archives website. Type the name of the website into the search box, and the machine displays all the archived pages for that website.
