There are two main ways performance advertisers measure on Twitter:(select two)

Server-to-server integration with DCM (DoubleClick Campaign Manager) is a correct answer because it allows advertisers to track conversions and other events directly from their servers to Twitter, providing a robust and reliable measurement method, especially for complex conversion funnels. The Twitter website tag is also a correct answer. It's a JavaScript snippet placed on an advertiser's website to track user actions, such as page views, purchases, or sign-ups, directly within the Twitter Ads platform. MobileIEM is not a recognized or standard method for performance advertisers to measure on Twitter; it appears to be a fabricated term.
