How to Permanently Delete Google Search History | Clear Google Search History
Google can find almost any information available online. In the process, it saves your search history for all Google-owned apps. When you perform a search on Google or YouTube (or any other Google service), the search query is saved not only to your browsing history, but also to Google’s search history.
While you can use other search engines for better privacy, Google and its services are a staple for most. Fortunately, you can delete your Google search history from your Google account in just a few minutes.
The obvious way to clear your history is to clear your browsing data from a web browser like Google Chrome, Firefox, or Safari. However, keep in mind that clearing your Chrome browsing history does not delete your search history. It only helps to clear your browsing history.
