A creative is the ad served to users on a webpage, app, or other digital environment. Creatives can be images, videos, audio, and other formats that get delivered to users. Creatives must be added to line items in order for them to serve ads. They can also be added to the creative library for later association to a line item.
Creatives are always associated with an advertiser.
Creative types
There are various creative types you can add to your network, between display, video, and audio, depending on the ad experience your advertiser is trying to create. Learn more about the types of display creatives or the types of video and audio creatives.
Good practice for hosted creatives
Some creative types are hosted directly in Ad Manager. Display creatives hosted in Ad Manager can be up to 1MB in size (see system maximums and limits for more, including video limits). Larger creative files may increase load times and may not represent the best user experience. Work with a professional to optimize creatives and the user experience for your website or app.
Follow industry guidelines for rich media creative. Review the Interactive Advertising Bureau (IAB) guidelines as a starting point.
In all cases, you must adhere to the Google Ad Manager terms and conditions as well as creative policies.
