Hang in there, you are almost there! In order to set up your first campaign, you need at least one creative. There are 3 different types of creatives.
HTML Tags: These are the most used creatives. HTML allows your creatives to display animations or even show the last viewed product to a user.
Images: These are the easiest creatives to add to the platform. You can easily batch drag and drop your images to the platform and Yieldr will add the sizes accordingly.
Videos: These are In-Stream videos that play right before, in the middle of, or after other video content, and use VAST XML to ensure proper rendering in players. Videos creatives have to be added one by one. The video file size must be less than 100Mb.
More information about how to add these to the platform is provided in the Creatives Category. Alternatively, you can click on the three creative types list here and it will direct you to the "how to create" page.
