Sending a request to a server is explicitly and inescapably part of requesting a web page; users explicitly grant permission for that request to be made obvious to you simply by making the request in the first place.
On the other hand, there's still an open question of what you do with that request data. Sending it to Google without permission is wrong, as it contains a slew of personally identifiable data that allows Google to build a massive profile of a specific user's behavior both across the internet, and in the real world.
