I don't spend a huge amount of time here - mainly keep an eye on the ClixAddon for ads & surveys, and play the ClixGrid while watching the evening news. But I still make between $40 & $50 most months, and that easily covers my phone & internet bill (plus a six-pack or two), and that is all I am really after.
I never want ClixSense to become a full-time job where I fear going out for the day in case I miss an offer.
Treat it as a hobby that rewards you, and you will be a lot happier than if you treat it as your main income stream with an expectation of earning X amount of dollars every day.
The previous posters who say that ClixSense has gotten much better over the years are correct. I actually stopped using the site a few years ago, because the only opportunities I could expect to get were PTC ads. I was earning less than 10 cents on most days. When I came back, it was full of surveys & offers & my earnings skyrocketed, and I do regret the time I spent away as I may have missed out on making several hundred dollars.
