Every time someone clicks your ad, you’ll pay for the click and the user will be directed to your website.
You can then track the actions of that user. For example, you can track if the person calls or submits a form.
All of this information is stored in the Adwords dashboard where you can see a variety of metrics including how much it cost to produce the actions you specified; in this case, phone calls and form submissions.
