Yesterday some members of Digital Point Forums were talking about a Google search results update and checking the results I would say they were correct. The thing that sticks out the most is that a lot of newish .com sites that are hosted in the UK have had a nice little boost in the Google.co.uk rankings.
Three of the .com sites that I have worked on over the last few months were up until yesterday strangely performing much better on Google.com then they were on Google.co.uk (all of these sites were hosted in the UK).
I have two possible theories about why this has happened either Google.co.uk is very careful about determining which .com sites are actually from the UK and it just takes a long time or, Google have just fixed there algorithm so that all UK hosted .com sites now get full Google.co.uk ranking benefit.
It is not just my clients who have been affected, I have noticed many .com sites are now performing much better, Kevin Gibbons site SEOptimise.com appears to have shot up in the rankings. Congratulations Kev.
I have not said anything to my clients yet, just in case their rankings disappear. I will wait until next week because I have made that mistake before.
