how much can we earn from ciao??

Well, if you can write a 120-word review in about 15 minutes (just a guess, I don't know how long it would actually take), that's four reviews an hour. If you have a day, that's ninety six dollars in a day. Presuming you know lots of things to review, and spend a year reviewing them, that's $35,040 a year, plus bonuses (this is very unlikely to ever happen though, I was just informing you). Imagine how much you'd get if you could write twenty an hour!

They pay $1 per standard review of 120 words, there's good potential there and a number of people have been paid as you will see from previous discussions. The link is on my profile page...

I've never heard of this particular site.
