conversion rate confusion

[rhddd]

I'm filling out a form/test about conversion rates and there is a two-part question that, I'm embarrassed to say, I don't even understand:

Can anyone please, please, please help me with this?

How many sales would it take to drive a $20 cost per sale for the keyword at the given spend level?

What would be the click conversion rate (CCR) for this keyword? Please illustrate the formula used to derive your answer.

Thanks for any advice

I got confused after, "I'm filling out a form/test...".

What would be the click conversion rate (CCR) for this keyword? Please illustrate the formula used to derive your answer.
100/(number of clicks/number of conversions)

(so if you have 200 clicks and 6 conversions your conversion rate is 3%)

the other question is a bit strange, presumably there's some other information that you already have from previous questions. If you pay $1 per click and make 5% conversion rate (1 sale per 20 clicks) each conversion is costing you 20 clicks - therefore $20 in PPC. It sounds like you have some cost per click figures and just need to worlk out how many sales you need to achieve for it to cost $20 per conversion?.

It's easier for you to slot your figures in and work backwards than me to think up what the actual formula would be though.

So is this part of the Google Adsense Expert course? :D

Gurtie, Thanks for the answer - actually this is for MSN
