Google stores a history of all search queries you made while signing up and binds them to your Google Account. You can now quickly clear this history from Google search results and stop going to the Google Account dashboard.
Keep in mind that Google uses your search history to get information about you. Deleting search history will make your search results less personalized.
How to delete the Google Search history on the desktop
To clear the Google Search history on the desktop, click Settings> Your data in the search box at the top right of the page below the right side of the search box.
Scroll down to the "Your Search Activity" section. To clear your entire Google search history, click the "Clear All Search Activity" button. Click the "Delete last hour" button to clear only the last hour of the search history.
How to Clear Google Search History on Mobile Device
On the smartphone, tap the menu button in the upper-left corner of the Google search results page.
Tap on "Your data in the search".
Scroll down to the "Delete Search Activity" section and tap Either "Delete Last Hour" or "Delete All Search Activity," depending on how much of your search history you want to delete.
How to stop Google tracking search history
Of course, Google continues to track search history after deleting. If you want to prevent Google from doing so, click the "Web and App Activity" option under "Google-wide controls" on the "Your data in the search" page.
From the Activity Controls page that appears, disable the "Web & App Activity" slider.
