3) your videos must have at least 10k views

4) you videos must been been watched for a total of 4,000 hours in the last 12 months

5) Live in a country where YouTube monetization is available (you can check this list to see if your country is supported)

6) Additionally if an AdSense account has been linked then that will help too!
