Google is tweaking is algorithm as it does regularly, we seems to get one of these “large” shakeups every two one three months now, where the results are significantly mixed up.
However, I can’t believe what’s going on at the moment is going to last, the results are truly weird and have some irrelevance creeping in. For example:
1. A number of US based sites creeping in financial based searches and ranking well, this is totally pointless in the UK as we can’t buy their products.
2. Duplicate results for the same search on the same page. eg: “SEO” on Google.co.uk
This may just be testing, and this post maybe largely irrelevant tomorrow, but I do hope it changes soon.
