Uploading standard creatives is a very simple process - just ensure the file size is equal to that of one of the acceptable ad unit banner sizes.
When launching campaigns we recommend to use one creative ad unit size per campaign. This is because each size will inherently come with different CPM’s and performance behaviours and it makes it easier to compare your results without having the data skewed by different creative sizes. It is very easy to set up the campaign exactly as you need it and then simply clone the campaign and add different creative ad unit sizes per campaign as you go.
