An updated WebmasterWorld thread has new reports of changes at Google.co.uk and Google.com.au.
Senior member internetheaven, who keeps an eye on the Google UK results said:
Google.co.uk is all over the place. The results for one of the more competitive terms here in the UK (and across the world!) have completely changed. All the major financial companies and associations that usually rank at the top have been pushed down in favour of a few smaller companys and the inner financial sections of "related" websites (e.g. the car insurance ad section of a used car sales magazine) -- plus several MFAs to boot!
It is a slow holiday weekend, so there is not yet much response to internetheaven's post, but this member is senior and I trust him. Have you noticed any major changes with big competitive terms?
