Google could have a complete list of almost everything you've ever looked at.

The site collects information on your searches, browsing history, YouTube videos you've watched and more. But it can all be seen – and deleted – from one page.

Google's My Activity page includes all of those searches and pages.

The list will at least include every Google search you've ever done while signed in. But if you use Google Chrome, it will also include just about every website you've ever visited, all catalogued by date and time, and completely searchable.

The list can be quite helpful. All of the information is completely searchable, so if you remember just one part of a website's name or only the day you visited it, for instance, you can find it back out again.

Google collects the information in part so that it can be useful to you – jogging your memory, helping you find past websites, and learning more about you so that it can recommend more relevant things. But it is mostly so that Google can use that information for its ads, learning what you're into and what marketing is most likely to appeal.
