Is it possible that some variations in results are caused by variations in what phone vs desktop, apps or browsers send to google when people search? FYI, I have my Windows Desktop Firefox homepage set to Google Advanced Search: https://www.google.com/advanced_search?hl=en&fg=1 https://www.google.com/advanced_search?hl=en&fg=1 and I never (almost) logon to my google account when I search. It would be nice to add "site or domain:" exclusions.
