hi I am making a report for my client and i am confused in putting the value of CPA. can anybody help me whether it cost per conversion per click or cost per conversion many per click. please help me it is very urgent.
It's "cost per conversion per click" ("Cost/Conv. 1-per-click" column in the UI). The AdWords Conversion Optimizer calculates according to this parameter, i.e. based on unique users (30-days cookie)
Conversion 1-Per Click is the actual performance of your campaign and your effort. Though Conversions Many Per Clicks are the total conversion on a single click and use to count as the conversion for client but for you the actual performance is counted for conversions 1 per click.
No need to calculate. Awords tool calculating it and showing you in your adwords interface. Just add the Conversion Per -1 Click column to see.
This new option allows you to bid based on the average amount you would like to pay for a conversion. For example, if you want to achieve an average CPA of $25, you could use this option and set your bid to be $25. Advertisers with CPA targets they would like to reach may prefer to use Target CPA so they can specify those goals directly. Thanks.
