I was going to comment on that site when you first mentioned in response to it, but got sidetracked,,,for days. It gave me the same numbers no matter how many time I closed the browser and came back. It didn't change. Which tells me it was loading a cookie and was redoing the info. Not very random to me.
Google does this a lot with your searches. Ever wonder why even if you spell it different or reorder the search, almost always comes back the same for pages and pages. What good is a million hit search that totally loses the original inquiry 4 pages into the returns? This of course after you advance through about 5 pages of useless advertising by paid sponsors.
I barely use google at all now. Duckduckgo and others.
Wait, what was the original question? lol
