normal web tracking : setup by webmaster / site owner. they only know what you did on THEIR web site. they only know stuff like what is your IP address, general location, pages you visited. they do not know who you are or anything about you.
facebook web tracking : they know who you are. they track you across MANY different web sites. you can visit 10 different sites owned by 10 different people and facebook can track it all.

I think Facebook is worse. Google seems to be more transparent but also has many more tentacles (for example, browser, search, phones, cloud internet, etc). At least they failed at creating a social network. Because Google owns a bigger platform, they can aggregate much more data, but they are fairly open about how they aggregate (or allow you to selectively decouple). Facebook on the other hand leverage the social graph more, and the interpersonal relationships are inherently not privacy preserving.
