The first thing to do after accessing the Campaigns section is creating an advertiser and start the campaign creation process. The definition of an advertiser, along with other useful terminology, can be found in this glossary.
From this section you will be able to create and manage/edit your previously created advertisers.
As soon as you click on the Create Advertiser Button, you will be asked to add the name of the company that is being promoted in the campaign.
Type the name and then select the IAB category the advertiser will have the ad listed under.
If no category is selected it will be automatically marked as IAB-24 as default.
Once finished please click on Create Advertiser at the bottom of the page in order to save.
