Suppose I spend $1000 on advertising a month, what is the realistic ROI that I can expect from this? Do you see varying ROI based on the networks like Clickbank or CJ? Please share your experience..
Your return on investment is going to vary greatly. Do not expect fantastic riches on your first campaigns. Some get lucky, but it is not realistic. I know people doing 500% ROI on some campaigns, but they usually don't last long. My answer: stop drooling over "what could be" and start testing on a small scale. Hope this helps!
ROI means returns of investment, there's an old saying, do not put your eggs in one basket. Smart advertising in PPC is necessary. I made $58 for every $5 i invest in my campaign. 100 x 0.05 = $5. Expect 2 to 3 sales in every 100 clicks. That's it.
It is not the business of CB or CJ or other affiliate network. It depends on some facts including market demands, ads platforms or networks, products or services, prices, keywords research and quality of traffic etc. I agree with evanlambda. Stop drooling. You don't know when you are well off if you have 20-50% profit.
