Why caching is done in google? Do the page that we get after clicking at a link on on SERPs is a cached page?
Caching is done, IMO, for webmasters to know when they're site was last updated and wgat pages were thoroughly crawled. The page you you get when you click on a SERP is NOT a cached page. You can see a the cached page from a link provided by Google beside most of the pages you find in SERPs. The links in SERPs are live links and just take you to the website/page you're looking for. Hope I answered your questions..
messed with my head a little. saw this same thread in the google forum and thought, where did all of the replies go?????
Cached pages are handy when the web site has gone offline. Also, if a given webpage has changed considerably since the SE crawled it, then viewing the cached page is a quick way of finding whatever it was you searched for. You may find that the live version of that page has changed so much, what you searched for is no longer there... Cryo.
