There are sites that require payment to view archived information. By clicking on "cached", those pages may be available free! Information that is purposefully deleted from a site may continue to be available by clicking on the cached option. Does Google have a right to make copies of copyrighted material? Has Google opened itself up to problems? Since anyone can opt out of being cached, there probably is no issue here-it''s an implied consent...

Recently when my domains were hacked and backups were deleted in the process, my blog was missing posts when it was restored. That is when I learned about the cached link, that has always been there, but I never paid attention to it. This option can be valuable for retrieving lost pages. Searching for lost pages is a simple process. Simply enter in the topic in front of the word "site" and then enter the site url. The search will send you to the page and the most recent cached page will be available. Google Cached, I love you has more information on how to retrieved lost web pages.

Google cached pages have a purpose besides helping to retrieve lost web pages like it did for the blog Jan''s Ideas. Google takes the snapshot of every page when Google crawls it and caches it in case the page is unavailable when a search is made, Google will then use this as a backup. The content that is cached is what Google uses to decide if the page is a relevant match for a search. This backup is helpful if it''s your page that is not available to Google or if it’s a page that matches your search but is temporarily not available to Google. Clicking on "cached" can also be helpful if there is a broken link or unavailable link to a site that came up in a search.
