Google Adwords or better known as your PPC(AdWords) campaign Ads are better served if they are viewed in advance to see if your own personal campaign appears when a user clicks for a certain keyword you optimized your AdWords campaign for.
That is with the case where you are targeting the same keyword as what the user typed in his browser and the user comes from the GEO location where you are targeting your Ad to appear.
For those who are looking for an easy way to do it, then I can only suggest that you use a pretty simple tool that gives you the user (the PPC speicalist) the advantage of seeing if your Ads appear when a user clicks a search query that your very Ads are optimized to appear for.
You can find the tool here... Pretty simple but very useful for PPC masters and newbies alike.
