Just know this: a major update that Google is testing has completely broken the ability for any external analytics service like Clicky to determine the search query used by a visitor arriving at your web site. Why would they do such a thing? Who knows. They aren't talking.
Now, Techmeme is buzzing with the story and Google scrambled to release a statement that reads:
Brett Tabke, founder of WebmasterWorld said:
I honestly don't think G is shortsighted enough to do something like that system wide. Websites would have little incentive to look to Google for traffic or optimize for Google. The focus would no longer be on Google for optimization. We wouldn't know what or how to optimize for keywords - optimization would be shots in the dark. Our only options would be to look for other big sources of traffic.
On the other hand, we have to respect a websites - even Google's - opportunity to innovate. I think we have to see what G is doing with the Ajax before passing final judgment on it and it's intentions. I doubt that it is Googles will to break log analyzers and keyword trackers with this test. I think that is a by-product of whatever Ajax implementation google is currently testing.
The discussion around this topic is pretty intense and high strung now. It will be interesting to see how Google moves forward with this test over time.
