The tracking history will show search made on Google, website visited, Images view and Youtube videos watched online.

Some of us might not want to call up our previous search history, we might even want to browse the web without footprints. But it could be helpful sometimes to call up our search history, we can easily do that in simple steps:

Type myactivity.google.com into the address bar of the browser, where you would normally put a web address.
Login to your Google account if you were not logged in, a dashboard will appear where you can bundle-view items, or view item individually.
You can specify what get saved through the activity controls on the left-hand menu.
Your search history is private and can be seen by only you, so do not keep your Google account signed in.
The tracking activity works across devices.
