As you know, Google pushed out version two of the Farmer/Panda update globally this week and more webmasters and SEOs are scratching their heads.
SearchMetrics released a study of what they say are the top 100 domains with the greatest gains and losses for the UK region. The thing is, people are questioning its accuracy.
A WebmasterWorld thread has people looking at the numbers as if they are indeed related 100% to the Panda update being rolled out in the UK. But as Google said, the rollout has not happened until this Monday and the data used in this report is from as far back as the Thursday before. The study said, "data was collated between the 5th & 12th of April 2011." Google 100% said it was not pushed out until the 12th. So what we saw late last week was not Panda rolling out and thus might make this data invalid.
That being said, they can easily run this report again and compare the results.
Anyhow, you can see many charts and data on the SearchMetrics blog. Here is one on eHow UK's drop:
Do you feel these results are accurate?
