Why do google search engine results vary from place to place and from different devices?

Google probably tries to give results according to Internet user. So, that user's place and device reflects into search engine results.

Google keeps into account your history. When you, for instance, often deny the top hits of Wikipedia but instead often click Urban Dictionary for your definitions, Google will adapt this pattern and help you reach your destination faster.

Depending on the history of the devices, this can vary.

Google tries to tailor the results to the location of the user. Of course in some countries some topics will be forbidden or not allowed so those will not show up.

Different geographical locations get different results. It's all about the country you are in with google.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
