When it comes to search-engine tests I do the obvious thing, I search for my name! Google gives me my site at the top. Duck Duck Go puts my site in place 10-15.
I share a name with an American baseball player, so I'm not surprised I don't come universally top.
(Yes I know that Google does personalized results, but even without that I "win".)
You're the 25th result on Google for me. How are you testing non-personalized results on Google?
It could be that it's localising the results geographically better. DDG's results have improved enormously for me recently, to the point that I completely forget it's not Google these days, whereas I used to use the !g bang about 80% of the time, but the one thing I do still fall back to Google for is local non-US-centric content.
All of those probably geolocate your IP to the same region, unless you were travelling the world at the time. You really need to use proxies or tor to get a genuinely non-personalised Google.
