A click on an ad extension incurs an additional charge to a normal click.

The statement is False because a click on an ad extension does not incur an additional charge beyond the normal click. In Microsoft Advertising, when a user clicks on an ad extension (such as a sitelink, call extension, or location extension), it is counted as part of the regular click on the ad. The charge is the same as if the user had clicked on the ad’s main headline or description. Ad extensions are designed to enhance the ad’s visibility and provide additional ways for users to engage, but they do not result in extra costs. This helps advertisers maximize the value of their ad spend by giving users more opportunities to interact with the ad without increasing the cost per click.
