I think in order to make $1 a day you have to be committed to your websites. You have to make sure that the visitors are consistent and that you are getting different visitors to your site each day. Make sure that you don't make too many sites that you can't handle it, as I learned that the hard way lol
i dont think so i only had one website sometime i am making around $3-$4 but some time $0 also but average i am making around $20 a month from last 3 months coz i start the website 3 months back
