Classic banner (web)

Overview
Formerly named "Default Banner" / "RTB+ Default Banner". The "Classic banner" creative template displays a simple banner.
Do not use the "Classic Banner" creative template for newsletter campaigns and other use cases where client side counting of impressions is not applicable/would not work. For such cases, use the dedicated creative template Newsletter/Email Banner. For more information, see Create newsletter insertions.

* About the "Acceptable sizes" field
By default, the width and height defined on format level (e. g. 300x250) is used. To accept additional sizes for the same ad slot, define them in the Acceptable sizes field in this form: width*height (e. g.: 300*250); separate multiple sizes by a comma and do not use any spaces.
- if you define one size, the size defined on format level will be overridden (replaced)
- if you enter multiple sizes, a multi-impression bid request is sent to the DSPs; the highest bid will win the auction, no matter which size it is
- to accept the format's size and additional sizes, enter the format's size, followed by the additional sizes
The sizes in multi-impression bid requests are sent in the order declared in the field Acceptable sizes. However, some DSPs may not support multi-impression bid requests: they will use the first size only and ignore the other sizes!
Note: In a Header Bidding setup (with prebid.js), the Acceptable sizes field has priority over sizes specified client-side in the prebid.js configuration. For more information, see Set up and manage client-side header bidding.
Features
Click management for HTML5 creatives
The Classic banner ad format is able to identify the click destination for HTML5 creatives by using:
- the click counting library; for more information, see Manage click counting
- the clicktag variables passed in the source of the iframe; Important: HTML5 creatives must have the click destination recognition implemented:

Limitations
All creative scripts are rendered within an iframe with fixed dimensions
Known issues
- the viewability module for the asynchronous one call format (iFrame in the “General settings” in Monetization fires the
viewundeterminedpixel in case of creative formats image and HTML5 and does nothing in case of creative scripts - the RTB click counting feature does not work in the case of the creatives that are placed within a cross-domain iframe; in this case, the click event, that is triggered in the iframe, is not accessible for the parent document
