Many Pop Ups on Google App

I really love Google, I prefer it over Safari (no offense Apple), but the only thing I hate about the app is all the pop ups that appear out of nowhere, like saying I have won an Amazon Gift card or that my iPhone has been infested with a virus etc, and I can’t seem to make them go away, or is it a way to block them? Any help would be appreciated!!
