I can confirm Google caffeine is now live in the UK serps. It's not yet a full roll out, but you can hit the caffeine results 50/50 in the UK as of Yesterday. Les SEO Expert
I have checked many keywords in Google.co.uk and found the results are exact same as it was. I also did use UK IP based proxy to access Google.co.uk and do the similar search, found nothing different either. Where did you get this info?
Well, if you're confirming it, how can anyone have any doubts. I can't say it's caffeine but there is something going on, Google traffic is up big time for many sites, down for many. Hunch is Caffeine coming soon, but can't confirm.
I just tested the UK google, and I like the results for my keywords! Definitely different than US datacenters
somethings happening as yesterday my site appeared on page 5 afer vanishing for a couple of months then today its completely disappeared again lets hope it will reappear again soon something strange is going on!!!
I have noticed some changes which I have thought were the caffeine update, but I think I'll wait for an official source to confirm it before believing it was infact the caffeine update.
