When a search engine user in the targeted area searches for the keywords or keyphrases that you chose, your ad enters an immediate online auction. Your ad is displayed when it matches bid and relevancy criteria, so you want to make sure that you have an appropriate budget size, and that you are bidding on keyphrases relevant to your products/services (such as those indicated on your website or landing page). You are not charged when your ad is displayed, but rather when someone clicks on your ad to take further action.
