So make sure you are logged into your google account, then go to this link. It provides demographic information Google has inferred about you based on your web-surfing habits.
Let's take a look at mine:
So we have my comics, check.
All WoW related sites, check.
My blog stuffs, check.
I'm a bit confused by the finance and law/government categories. But see how at the bottom it says I am a 25-34 year old guy? I wonder exactly which category it was that put me over to the male side. I'm guessing the Gaming and I wonder when the "Games - Online Games - Massive Multiplayer" category won't be automatically tagged as male.
I find the 25-34 age bracket amusing as well because I wish I was still there! As of last year I am no longer in that age category. Also, I guess the Shopping category wasn't enough to tag me female? Does this take volume of surfing into account? Maybe I need to check out Pinterest more?
