How do you see what I searched on Google?

You can go to the My Activity page on Google to see everything Google knows about you. You’ll find every search you’ve made, most of the websites you’ve visited — because of Google Analytics — and even more if you’re signed into a Google account. If you’ve used a Google app, then that information shows up as well.
