Welcome to the Filter bubble.

Or should I say, welcome to the outside of the bubble.

Cor-el, thanks for your response. It seems to me that the reason the results for the same search term differ between a private and default window is that a private window takes me to google.com rather than google.com.au. If a person in Australia just wanted to keep their browsing session private, I don't understand why a private window would refer you to a Google international address. Surely this would take the relevance away from certain search results returned as they would not relate specifically to your own country. In other words, if I tell someone in Australia to search for a specific topic which I know appears on the first page of Google in Australia, if they are in private browsing mode and using google.com, they would tell me they can't find the same information because they can't see it from google.com.

I'm not sure I follow your response re cookies - I have limited knowledge in this regard.
