So, Google places.
I've noticed something....weird, and I was curious as to whether anyone else has observed it.
At the same computer, same time, no Google login, 3 different browsers (IE, FF, Chrome) all provided 3 completely different results for the same search term on Google places for one of my clients. On FF they appeared on the 2nd page. On IE, the 4th, on Chrome the 6th. My decision to now work solely in FF when reporting is, of course, unrelated and completely coincidental. Honest 'guv.
Perhaps, with Places, Google has introduced a 'randomiser' to their results, to prevent accusations of favoritism and anti-competitive behavior? Has anyone else observed this phenomenon?
