Unhappy with the increased social media results now showing up in your Google searching, but don’t want to log out of your Google Account? Here are several ways to turn off “Search Plus Your World” while remaining logged in.

De-personalize an existing Google SERP (Search Engine Results Page)

Click the person and globe icons (upper right of SERP) to toggle between personalized and generic results. This works, but I've found it a little buggy.

You can also add the parameter &pws=0 to the URL of the Google page.

Or Browse Incognito in Chrome

Open Chrome. Click the wrench icon to open Chrome's settings. Select “New Incognito Window”
(Keyword shortcut: CTRL-Shift-N)

In the new window, Chrome's logo goes all Cloak and Dagger.

Or Change your Google Account settings

The search settings include a choice to display personalized results or not.
