Why would someone need their Google Search History?

Have you ever wondered what you have used Google to search for over the years?

Now you can easily find out what you looked for in April 2013. Neat!

Google have now allowed you to do such that.

Recently, Google have made their new feature available to all their users. The feature allows users to download their search history. Downloading the history is as simple as logging into Google and going to the Google history page.

The page provides you with lots of information, including hourly search activity, daily search activity and monthly search activity. However, this is nothing compared to the detail below the dashboard.

Google shows all the terms and time you searched for. Now ... this is fun!

You can go back to whenever you want. Of course, you will be able to find many embarrassing things you looked for in the past. No no  no ... I am not only talking about your weird taste in porn. Haha! One of the funniest thing I found in my search history was I actually searched for Yahoo and Hotmail! That was years ago, though. Back when I never used the bookmark function.

Bear in mind that Google only record your search history when you have logged into your Google account. That means if you are logged on your mobile phone, whatever you look for is recorded. This, of course, includes the commands you issue to Google Now.

Furthermore, you are also allowed to download your entire search history. This will be sent to your email. You will also be able to delete your entire search history. However, Google warn that you may lose everything you have done over the years. (I have not tried deleting it, so I am not too sure what it means.)

This all sounds kinda fun. Beware that now you should not leave your computer logged on at anytime. This may go to your smartphone as well. It is now possible for anyone to look at your search history and, of course, download it, too. Watch out!

Anyway, this leads to my question "Why would someone need their Google Search History?"
