Charges typically come from two sources: impressions and clicks. An impression is when your ad pops up or is shown on a website. A click is when someone clicks or taps on your ad and visits your website. Depending on your ad type, you'll be charged differently.
Pro tip: There is no additional fee for adding a conversion tag to your ads! A conversion tag is a piece of code that you can add to your site whenever you want to track a specific customer action, such as making a purchase, booking an appointment, or signing up for an event. The tag in the ad is linked to a tag on your web page, so you can easily understand the return on your investment, and where your conversions are coming from.
