I've heard a lot about websites saved thanks to Google's cached copies of them. Where can I access these cached copies?
There are several ways of doing this!
If you do a regular Google search, in the above image, you can click on the Green arrow () and that will bring up a drop-down mean from which you can selected the Cached version.
Secondly, if you are already at a website, and you want to check its' cached version, then you can simply add cache: to the front of the URL, and....
press Enter if your address bar allows Google searches (Like Chrome)
Copy and paste the above full URL into the Google Search
