Sizmek (Amazon Ad Server) clickTag code

This is the click declaration Foldwrap writes into an HTML5 export for Sizmek (Amazon Ad Server), with a placeholder destination. Copy it into your own creative if you are hand-building the banner.

Sizmek (Amazon Ad Server) clickTag
var clickTag = "https://www.example.com/landing";

Sizmek (Amazon Ad Server) sets the destination at trafficking time, so an empty value in the exported file is correct and expected.

Why Sizmek (Amazon Ad Server) rejects a banner

These are the rules Foldwrap checks a package against before it is delivered to Sizmek (Amazon Ad Server). Each is derived from the requirements above, so a constraint Sizmek (Amazon Ad Server) does not state is not checked and is not listed.

  • errorNo entry HTMLAdd index.html at the ZIP root.
  • errorReferenced asset is not in the packageRe-export the creative so every referenced asset is bundled.
  • warningElement destinations flatten hereKeep a target that supports element destinations in the set, or set a default click URL that suits every element.

Foldwrap runs these checks on every package it exports for Sizmek (Amazon Ad Server), and names the creative and the constraint when one fails.

Frequently asked

What is the maximum file size for a Sizmek (Amazon Ad Server) HTML5 banner?
Sizmek (Amazon Ad Server) does not publish a file size cap for HTML5 packages that we have been able to source. Ask your account contact for the figure that applies to your placement rather than assuming an industry default.
How do I set the clickTag for Sizmek (Amazon Ad Server)?
Declare clickTag in the creative. Sizmek (Amazon Ad Server) replaces the value when the ad is trafficked, so exporting with an empty destination is normal and correct.
Can a Sizmek (Amazon Ad Server) banner have more than one clickable link?
No. Sizmek (Amazon Ad Server) takes a single click destination for the whole banner, so every click goes to the same page regardless of which element was clicked.
