Both Google and Facebook are Advertisement Company and as you know Facebook is closed competitor of Google so Google never want the trust and brand value of Facebook is equal to Google.

Twitter is Micro blogging based social networking website but there is not any market comparison so it is partiality with Facebook as compared to twitter.
