StartApp currently offers 3 different creative types.

Enriched ad

Enriched Ad creatives (Rich Text) are high volume creatives. This creative type represents about 70% of StartApp's traffic. We recommend adding them to every campaign in order to make sure you are getting as much volume as possible.  

For app install campaigns - the app title, description, and the icon will automatically be extracted from the relevant Application Store, based on the package name entered in the campaign "What are you promoting?" section.

Note that all fields can be edited including the icon image if necessary.

For mobile content campaigns - you are free to create and upload the image, title, and description. 

Enriched Ad creatives will be presented in the following ad types: 

  • OfferWall
