As a standard member you can't do much. You will receive a few 1 cent ads to view and 1 cent for each new referral that join under you but that's it! I was a standard member for a very long time and managed to earn only 3$! Two of those three dollars came from one of my referrals that upgraded under me and that was also the time when I decided to finally upgrade.
A lot of people earn good money with Clixsense but no one is earning anythng without an upgrade unless they come from the US and get all the targeted ads. With an upgraded account for only 10$ you will receive 10 cent for each new referral that simply sign up under you! That's 10 times more than you would get as a standard member. Besides that, you will also see a lot of ads the first day you upgrade. Around 250 ads will be waiting for you, each one is worth 1 cent or more! This is of course not all! You will also receive 2$ from each referrals that decide to upgrade in your FIVE referrals levels! It means that if you will earn money from the referrals that your referrals are having! This can be a lot of cash if you got an active downline. There is also a new feature at Clixsense that allow upgraded members to earn 10% of ad value for each ad your premium first level referrals view!
I hope that more people will understand the earning potential of this program when they read this. After 4 years it's still paying but all you see at ptc sites are the neobux ads.
