How to book interstitials in your web solution in Google Ad Manager

2024-07-04 09:18:21 UTC

This guide will go through the basics of booking image interstitials in Google Ad Manager in your ePaper solution for web.

If you are not familiar with booking ads in Google Ad Manager (e.g. on your website), we recommend you to book through the Visiolink Publishing Hub instead. Implementing Google Ads interstitials will disable the possibility to book from the publishing hub.

1. Create Ad Units   

You can place up to five fixed ad positions in your ePaper. In addition, you can create a frequency controlled position that is displayed dependent on the number of swipes the user makes. As a default this is set to 12 swipes. The number can be set in the publishing hub. 

The fixed positions are placed after a page number in the publication. You can place them e.g. after page 1, after page 5 and after page 9. The page numbers must be odd numbers. The frequency position works fine with the fixed positions, as it will simply be shown X number of swipes after any ad has been displayed.

It is possible to place different ad units in different publications if you have more than one title (controlled by prefixes in the Visiolink system).  

2. Book creatives in your preferred size

As a default, we support all the most relevant standard sizes available in Google Ad Manager. Below, we have listed our recommendations.  

1x1: You can use the 1x1 size to book any ad size if you check the box "Allow creative size to differ from ad unit size". 
The following list is the full span of ad sizes supported in the web reader: 
1024x768: Recommended for best ratio between size and speed of execution. 
If more than one ad is booked on the same placement, the ads will be rotated to display the ads evenly.

Empty ad units will be ignored, so that the user swipes to the next page (there might be a short delay when swiping past an empty ad unit, as we will need to ask the ad unit if there are any ads booked). 

NOTE: As the web reader is seen as a single page system by Google, it is not possible to book the same ad on two different ad units at the same time. Google will prevent the ad on one of the ad units to be shown. If you wish to book an ad to be shown on more than one position, please use the frequency controlled position. 

3. Provide Visiolink with account ID and ad unit IDs

Visiolink will need an overview of which ad units should be placed after which pages in which publications. Furthermore, we need the account ID of your Google Ad Manager account.

It could look like this:

Account ID
Placements Page 1 Page 5 Page 9 Frequency
Newspaper 1 ad unit IDs news1_p1 news1_p5 news1_p9 news1_freq
Newspaper 2 ad unit IDs news2_p1 news2_p5 news2_p9 news2_freq


Key-value Targeting

We also have support for key-values. When creating your Line Item you can choose to target these key-values. Key-value are created under "Inventory" → "Key-values".


1. folderID: This gives you the opportunity to target a specific folder with the "folderID"
from the Visiolink Publishing Hub. When you target a specific "folderID", the ad will only be shown in the specific title.

NB: The key must be created precisely like this: "folderID" and with correct value.

2. pubdate: This gives you the opportunity to target a specific issue based on the date of the publication. When you target a specific "pubdate", the ad will only be shown in issues with this publication date.

NB: The key must be created precisely like this: "pubdate" and values must be written as dates in this format: YYYY-MM-DD (e.g. 2024-04-24)
