Question : Adwords CPC and Daily Limits

Hi,
I have just set up an Adwords campaign and am unclear about a few things that I am hoping someone can explain in simple terms.

I have set up a Standard Edition, with a daily limit of $1.60 and a minimum of 0.05 cents CPC.

I have set up a prepay option and didn't want to spend more than $50 per month.

So I am a bit nervous as to how this will work.  I do not want to pay anymore that 50 dollars and I don't know when they are going to charge me?  I have given a credit card, so will they bill me each month?  How can I ensure they do?  Have I set everything up properley to ensure I don't have to pay anymore?

I hope someone can clear this up for me as it wasn't outlined clearly for me?

Answer : Adwords CPC and Daily Limits

$1.60 * 31 is less than $50 so you should be ok.

However, I have seen AdWords exceed my limits at times. They try and average on the limit so some days may be higher and others lower.

On prepay you have to manually make payments (in advance). So AdWords does not take your money, you give it. You have to put some money in your AdWord account before it will start.
