An advertiser is ready to build their mobile ad campaign and they want their ads to serve on any modern browser.Which ad inventory options should they select?

Analysis of Correct Answer(s)

The question asks how to target a mobile ad campaign to serve on any modern browser. The correct selection is Smartphone and Tablet because these are the two primary device categories that constitute "mobile" inventory in Campaign Manager 360's targeting options.

• Selecting these device types ensures the campaign is exclusively focused on mobile environments.
• This targeting includes inventory from both mobile web browsers and mobile applications on those devices. By choosing these broad categories, the advertiser ensures their ads are eligible to serve on the required browser-based inventory.

Analysis of Incorrect Options

• Smartphone and desktop web: This option is incorrect because the campaign is specified as a mobile campaign. Including desktop web inventory would violate this core requirement.

• Mobile in-app and in-stream video: This is too restrictive. The key requirement is to serve on browsers, but Mobile in-app explicitly excludes mobile web inventory. Furthermore, in-stream video is a specific ad format, not a comprehensive inventory selection.

• Mobile-in app and out-stream video: Similar to the previous option, this is incorrect because it focuses on mobile in-app inventory, thereby excluding the necessary mobile browser environment. It also limits the campaign to a specific video format.
