Google has been tracking us everywhere you go. Check your ‘Web and App Activity’ on your account and everything you’ve done and everywhere you’ve been is logged on there. If you use a Google account, then they can go through your search history, including what you watch on YouTube and gives this information to advertisers to cater ads that are specific to your cyber behaviour and interests.
If you feel violated or a little creeped out and want to go incognito – this is how:
Go to ‘https://history.google.com/history/’ and change the history to “all time”. This should bring up all the web pages you’ve ever searched or been on. Select ‘Today’ and press ‘Delete’.
