How can i earn by a website? If there is no ad and it is not a e commerce site. If any one sign up or visit my website, will i get money? How do Quora, Facebook and other social sites make money when they launch, as there will be no advertisers willing to advertise on the site in the initial period? Am I right, if I think that they would not get any profit until they get advertisers or is there any other way they make profit?
