The topic of Google Still Showing Different Results Base on Case Sensitivity seems to still be an issue every now and then.
Again, Google says they do not differentiate results base on case sensitivity:
Google searches are NOT case sensitive. All letters, regardless of how you type them, will be understood as lower case. For example, searches for george washington, George Washington, and gEoRgE wAsHiNgToN will all return the same results.
But new reports from Cre8asite Forums shows some people noticing the same thing. I.e. Google showing different results based on case sensitivity.
When I brought this up last time, Matt Cutts of Google commented:
Hey Barry, I'm having trouble recreating this example, and I'm wondering whether you happened to hit different data centers when you were doing these two queries. Can you consistently reproduce different results with upper/lowercase? I'd be curious to know..
I saw it over and over again, but then stopped bothering to look. But now the topic sprung up again. I personally don't see it at the moment. This leads me to believe that it might not be case sensitivity issue but rather us hitting different Google data centers within the same second. I am not sure, but this topic is for sure not a new one.
Cre8asite Forums moderator, Barry Welford, is concerned. He told me, "I think it's clearly a real phenomenon, that is reproducible. It's somewhat scary that we can not get any official Google explanation that makes sense. It would imply that no one is really sure why the Google algorithm is doing this."
