Google AdWords

Can anyone explain to me how Google AdWords works as far as the money I would have to spend. For example I have an opportunity to utilize a $100 coupon. I was searching thru the rules and ready to sign up and read something to the effect of a $500 threshold and this scared me off.

I can't afford to spend $500. Can I cancel my account after $100?

Thanks very much. I look forward to your answers.

Edit: whoops...way to dig up an old thread...sorry.

Google Adwords is a service that lets you create and run ads for your business, quickly and simply. R

You can set the daily budget limit in google adwords. Your ads will not get served after the daily budget limit is depleted.

You can set daily spending limit. The campaign will be paused after the daily spend limit is depleted.So you need not to worry about that.

Google ad words are the best tool for keyword analysis. we can chose keywords which have low traffic and high searches.
