I see many people saying that they rely on the creation of many (sometimes hundreds) websites to get their revenue from adsense. Some others rely on a limited amount of websites. My question is: If one chooses to create douzens of websites over the month/years to generate revenue, what is the best/cheapest/most efficient way to do it? Do you create websites with free hosts with subdomains. Or do you buy a .com or .info domain for each of your websites? I'm talking about a regular website, I don't like blogs. thanks!
My advice is to concentrate at one site and work until it gets good traffic and able to sustain before thinking of building a second site.
