If you made a search while logged in with your current Gmail or Google account, it’s been recorded. We’re not just taking about the recent searches that pop up on your current machine. We’re talking every search you’ve made on every device.
Yes indeed it doesn’t matter whether your searches were done on a mobile or desktop, they’ve all been stored, and they’re waiting for you to rediscover them.
On top of being able to see every search you’ve made, as well as the exact date and time they were made, you can go all meta and search your own search history for forgotten gems and fond memories.

Are you curious? We sure were when we found out.

So, how can you see every Google search you’ve ever made?
