Google Cache is nothing but a snapshot or a copy of a page stored by Google as a back-up. Google usually takes a snapshot of each page it examines and caches or stores that version as a back-up. The cached version is what Google uses to judge if a page is a good match for our query. Google’s servers are typically much faster than many web servers, we can often access a page’s cached version faster than the page itself.
Basically every result of our search includes a Cached link. Clicking on that link takes you to the Google cached version of that particular web page, instead of taking you to the current version of the page.
This is useful if the original page is unavailable because of any of the following reason:
1 Internet congestion
2 A down, overloaded, or just slow website
3 The owner’s recently removing the page from the Web
Sometimes a site that requires registration or a subscription can access the cached version from that particular site.
You can always access page’s cached version faster than the page itself as we all know that google’s servers are typically much more faster than any web servers.
If you ever find that Google is returning a link to a page that appears to have little to do with your query, or if you can not find the information that you are looking for on the current version of the page, then you can just take a look at the cached version.
**How To access Google Cache: **
Just go to Google Web Search text box and add the keyword cache: in front of the URL that you would like to see. Ex. cache:eukhost.com
There is “cached” link in each of the Google Web Search results, except for those web pages that do not allow Google Web Search to cache or snapshot on them. If there is this “Cached” link, just click.
With reference to Google Webmaster Tools Help on Remove a page or site from Google’s search results, a web page will not be available in Google Cache database if it is not visible to search engine crawler.
3)In Google Chrome web browser, just use its Address bar as Google Web Search text box
Google Cache shows a page to be like as it was when Google last crawled it successfully, so it may be outdated. Google doesn't store images, scripts and other embedded objects, but it tries to retrieve them from their original location. If the page is down, most of the external resources won't be accessible and the page will load slowly.
