Clixsense really pays you money, there is no doubt about it. Everyday you can earn upto$0.04 or so just by viewing advertisements. And also you can play Clixgrid where you can earn upto$10 if you are extremely lucky. Atleast you can earn some money by these two.
But recently they have decided to stop delivering paid ads and clixgrid game. So you cannot earn from them now. The only way to earn here now is by completing surveys and doing tasks provided by Crowdflower, a crowdfunding company. Clixsense also donot support rental referrals feature.
From my personal experience I would suggest not to waste your valuable time here only for$40 a month which is approximately 2600 INR.
Regarding tasks, I would like to say that while doing the tasks you have to be extremely careful because one wrong answer and you are out of the task. One task requires 10-20 minutes. So if you don’t pay much attention you will not get paid and also your time will be wasted simply. But if you learn to do it you may earn$1 -$5 easily in one day. Note that these tasks are not available 24/7. You have to check regularly for any new tasks.
Regarding survey, you have to fill up your details carefully and accurately. Yet there is maximum chance that you will not get qualified for the surveys. If you get qualified then congratulations you may earn upto$1 -$4 a day.
The website interface is difficult to understand for new users and the customer service is not prompt. They may take 2-3 business days to get in touch with you. I will not recommend you to join Clixsense just for a small sum of money and wasting your valuable time. But if you wish to join then you may use this link https://clixsense.com/?11417824 and experience how the website is.
