Many people have spotted a large amount of US based listings appear for queries on Google UK this morning.
Two of the SERPs I noticed changes for were queries on search marketing and Kevin Gibbons. Both of these results are normally dominated by UK listings, but today these are mixed with US results which do not normally feature unless performing a query on Google.com.
Here’s some of the tweets on Twitter from more users who have noticed the same thing occurring:
As I mentioned on Twitter, I have seen this happening a few times in the past and it is normally a temporary change which is quickly switched back. I would expect this to be the case again, but good to see that so many people are on the ball by noticing this straight away!
