Yep, PPC can start instant traffic, as can links on busy existing sites. For organics its unlikely you will have much traffic/ rankings in 24 hours, within a few days is reasonable. Though it usually has to be something new, interesting or contraversial.
I mean HOW? What tools to use? What idea should be implemented? Where to get design ideas? How to design site so fast? How to deal with programming part? How to deal with testing part? How to generate fast traffic? etc.. etc..
yes, possible. Link exchanges and links at places where you can get great fererral traffic. The question is why would that website link to you. 1. if your website has traffic, which we are discussing we do not have. That is what we are trying to generate. 2. Paid Advertising 3. Or if it's a free service of some sort that links to other websites. You have to make it unique enough to be caught in. Take the idea of www.milliondollarhomepage.com he started in late August, and soon he became a mover and shaker in Alexa, featured on their homepage. He has not only generated traffic, but also made $816,600 at the time of this post.
Getting listed on digg or slashdot can produce what you are asking for. PPC campaigns:Adwords etc Buying links on busy relevant sites. Creating tools: Shawn created the keyword tracker one evening (from what I read) and 2 years on it is still getting busier. Unique Idea: the milliondollar homepage Though I dont know why you need traffic in 24 hours specifically.
By using free articles and other aggregated content and some cheap template you could create 30 page sites in even less than 2 hours. However I don't think such a bussiness model will pay off in the long run (even if you manage to lure some visitors there). My advice would be to better create a quality 30 page site in whatever time it takes to do so.
How much successful affiliate sites are? Let me take an example- If I create an affiliate site of around 30 pages related to loans in uk, say about personal loan, business loan, car loan, home loan etc. and let us assume it is an average selling site, than how much i can get out of it?
