I just started a PPC campain and the last couple days I've had about 400 clicks, but haven't had any sales. Is there an average that I can go by for example one sale per 1000 clicks, 5000 clicks, or 10,000 clicks or any estimate? I'm not sure how much I should spend and don't have much money right now and bad credit so I can't get a credit card. Right now I can probably spend $100 a week, if I can get 2 sales a week that would be good to get me started and can I can keep investing back in. My website is a website created by my affiliate and I've read you should get your own website so it's different.
