There has been lots of chatter about a recent shift in ranking by Google with US based sites ranking in Google.co.uk, seoptimise and Search Round Table reported in articles and there was plenty of tweets about the movement. It’s caused a few problems with plenty of UK sites moving down the rankings due to the influx of US based sites.
It’s hard to quantify sometimes what has shifted in the rankings has done as you don’t have before and after data of the top 20, 30, 40 rankings.
Fortunately I have a report from January the 18th 2009 for the top 40 sites in google.co.uk on a search for “commercial laundry equipment”.
I’ve then taken the top 40 websites for the same search query today and the difference is concerning with US sites ranking in the place of many good UK sites. There is also sites from Belgium, India, Spain and China ranking in Google.co.uk.
The list is big so I have added it into a Google Docs Spreadsheet which can be seen by clicking the image.
It would be great to get someone from Google to have a look over this. If anyone has seen something similar with their clients or SERP’s post the details below in a comment. Also link to your own blog with an example of the movement of US sites in the UK rankings.
UPDATE 17/06 : Fresh Egg have an article on a similar problem with the key phrase Pet Surgery. Check out the article which has a great conspiracy theory behind the US sites ranking.
