You'll have read over at SERoundtable that a recent update of Google UK seemed to flood the results with Aussi results - lots of .com.au results.
Well. Look at this; the number #1 result for 'video' is
video.google.co.kr. That's Korea and not the UK.
It even looks as if Google are having to run AdWords to point users to
YouTube.co.uk. Should someone point the YouTube people at Google's geo-targeting options on the webmaster console? Of course, there is no way Google's algo should link Korea is the best destination for UK searchers.
Also... notice those two spyware ads? For
spyware371.cn. Well that's an example of a company double serving which is against Google's AdWords T&Cs.
Also... and this is important; don't click on either of those two ads; both attempt to launch an .exe (and are probably a virus/spyware). This is also against Google's T&Cs.
Not the best set of results in Google's history.
