How to set campaign

[Rolozo]

I have found and confirmed by ww members that click estimation is not quite good.
Then i want to ask what is best way to set CPC and have right estimation of clicks/day?
Without setting correct CPC Campaign can run into loss.And surely it is completely loss.

The only way to find out is to test. Even if the estimates were 100% accurate, you still need to test different cpc to find the optimum profit. So forget about click estimates, find your list of targetted keywords and test them.

There are so many other factors involved in making a campaign profitable, click estimates are just that, estimates, to give you a guide as to how much traffic you may get.

Remember, your ad copy could be great and get you 10% clickthrough with a cheap cpc, or rubbish and get you 0.5% clickthrough with high cpc: thats where your profit or loss will happen, not because of googles click estimates.

Test test test, its the only way.
