How to save creative material

Please label files using the following naming convention:
Language_size_client_campaign_version.filetype (ex. en_300x250_abctowing_summercampaign_v1.swf)
Files uploaded in a compressed format (i.e., zip files) can exceed size parameters; proper naming convention is still required (e.g. en_300x250_abctowing_summercampaign_v1.zip)

Working with Flash creative

  • Flash ads should have “clickTag” coded into the creative. Please click here for clickTAG information
  • Static back-up image files (gif, jpg, png) are required for all flash files; size parameters still apply
  • Creative should always open a new browser window when clicked
  • Flash creative can animate for a maximum of 30 seconds or three loops. Refer to IAB specifications above.

How to send creative material

  • It is preferred to have files sent in a compressed format
