Before I started writing this post I found this post on webmasterworld in the webmasterworld thread you can see XOC point out he is ranking for Boxter in google.com .. the reason I have pointed this out is to stop people saying Google will ban you or move you off the first page etc etc..
The first Question I asked myself was why would I need a Google cached link in the serps :
Common arguments are what if your site is down people can’t see your site, well I run a blog I want people to interact with my site and see the latest comments that I have allowed I don’t want to wake up in the morning and find someone has left Matt Cutts cell number on my blog and Google has cached it (Google is quick at getting data slow at removing selective bits of your site)
so again I asked myself why would I need a google cached link… I mean I have seen sites like XOC’s hold rankings for years and all my new posts that rank in Google don’t have a cached link for days sometimes take the cleaners in london post early today:http://www.google.co.uk/search?q=cleaners+in+london
Another argument was people like to see how Google see’s their site, the fact that google show you text version and a full version, but they also say “It is a snapshot of the page as it appeared on 7 Nov 2009 20:45:03 GMT. The current page could have changed in the meantime.” should be a signal that the data could be wrong but I can get real time what Googlebot see’s
So the only reason I can see why I should leave the Google Cached link is so that other people can see what my website looks like in Googles eyes and why would I do that ?
