Under the HTML tab of a creative demo page, you will see four tabs. All except ‘Custom’ are "dynamic" views, where you can browse through random combinations of ad creative.
- "IAB standard" – a dynamic view of ads compliant with the Internet Advertising Bureau (IAB) Standard Ad Unit sizes. The majority of ad impressions take place in these widely accepted sizes.
- "Mobile" – a dynamic view of small ad formats, shown mostly on mobile devices
- "Additional" – a dynamic view of additional sizes (for example, those available in specific regions)
- "Custom" – a view of any possible ad combination. Using this tab, you are able to choose your own parameters to view available ad creative that matches your selection.
