This guide provides instructions for advertisers and media agencies on how to correctly configure creatives for inventory using the High-Impact.js framework.

• For creatives produced by SeenThis:

  You can skip these instructions – all necessary code is already included in the ad tag.

• For other creatives:

  If you are using your own responsive HTML5 ads or third-party tags, follow the steps below to ensure the ads display correctly.

  • Ad specifications: Select the ad size agreed upon with the publisher. Always check with the publisher contact for the exact dimensions and safe zones before launch.
  • Static images: Some publishers allow static image formats. Verify with the publisher if this is an approved option.

Implementation options

You can choose to include the High-Impact.js client code in two different ways:

1. When uploading the ad in the DSP / Ad server.

or

2. When the ad is produced.

Option 2. When the ad is produced

Embed the High-Impact.js client code directly in the HTML when the ad is produced.

Insert the following snippet directly into the ad’s HTML:

<script src="<https://t.seenthis.se/public/high-impact/client/1.0.4/client.js>"></script>

Note: The script client.js is hosted by SeenThis for convenience. If your policy requires it, you may copy and host the script on your own servers.
