As you may be aware that Google Chrome tracks down all cookies and what you search for and based on what you search you may see different ads. This is a business model of Google on earning from data. Your data is way important. I do believe that data should be private, that's the reason I use Brave for couple of months.
If you choose to see or give attention to ads from publishers you may earn BAT tokens.
Let me be your referral if you decide to move to Brave:
