does facebook know what i am searching?

[Neha]

Yesterday i saw in my news field a suggested post related to a dedicated web hosting site. I was surprised by this as me or any of my friends are not related to web hosting or any other thing related to internet......i am a commerce student and all my friends are of this background only.
But what made me suspicious is the fact that i was actually searching about web-hosting for last two days.(which i have never done before in my life.)....n i was particularly searching for a special type of web host with very high bandwidth ......and that's what facebook is showing me now......................I never searched on facebook or liked any page related to this on facebook....but my facebook is always on when i am googling other stuff in new-tab
