Step 4: Finding out what ad positions you need before uploading your files

Knowing what ad positions you’re going to be using before uploading your files is important. In the future this will be explained in every specsheet, but for now it’s important to know how to find out for yourself.

Please note: All files uploaded within the same creative are available for all ad positions. This means that if you upload assets that are used by multiple banners, you do not need to upload them for other ad positions, and using the same filenames for every separate banner might cause issues when used by multiple banners as well.

Some good rules to follow:

• If the width and height of your .html file are IAB (728x90, 300x250, 160x600, 320x240, et cetera) then that .html file requires its own ad position.
• Layers files like skins are generally associated with the ad position that is the highest on the page. So usually this means the leaderboard (728x90), billboard (970x250) or Custom (1x1) positions.

An example. Say you are creating an APTO with 2 IAB banners. This consists of the following files:

• Fullwidth header
• 2 skins
• Medium rectangle
• Skyscraper

This setup requires 3 ad positions. A leaderboard position for the header + skins, a rectangle position for the rectangle and a skyscraper position for the skyscraper.

The first thing you do is you upload all your files; this will show you the below result.

Here you can see that the 120x600 and the 300x250 have been recognized as the ad positions and the header + skins have been recognized as layers.

To make sure everything is in the right place you can follow these steps.

Select the 300x250.html file and press the "move selected ad elements" button in the top right of the interface.

Select the "Create a new ad position and move selected ad elements to this new ad position" radio button and submit the changes.

Now your 300x250.html has been transferred to a new ad position.

Go back to the Skyscraper tab and select the 120x600.html and do the same thing with this element. Press the "move selected ad elements" button and "create a new ad position and move selected ad elements to this new ad position".

Now you have 3 ad positions, a pixel position for the header + skins, a rectangle position for the 300x250 and a skyscraper position for the 120x600.

You don’t need to upload your assets to all the ad positions. The assets are shared between all the ad positions in a creative.
