They are spot on with age and gender. However, I am not interested in Bollywood or dating! Seems no way to edit what they think your interests are. However, I see that you can opt out of tailored ads.
It wrongly thinks I'm female & mostly interested in news, though it got my age in the correct range. I block ads when using Chrome, so they've got nothing on me!
a giver, i just don't like some knowing my business. its not theirs that's for certain. I disliked the street map thingy, and not in favour of cctv, being monitored or tracked on purchases, why should anyone like it.
I see I'm interested in Citroen and Fiat cars and apartments for the over 55s. I must surf the web in my sleep because I can't remember ever looking for any of them.
