## Ad server code

A snippet of code is required to link the ad placements to your ad server.&#x20;

Here is a sample code of the code for the **Medium Rectangle (300x250 pixels) or Large Skyscraper (300x600 pixels)** ad unit.

```
<script async data-cookieconsent="necessary" src="https://securepubads.g.doubleclick.net/tag/js/gpt.js"></script>

<script data-cookieconsent="marketing">
  window.googletag = window.googletag || {cmd: []};
  googletag.cmd.push(function() {
    googletag.defineSlot('/5748/scm.main', [[300, 250], [300, 600]], 'r1301').setTargeting('adloc', ['r1301']).addService(googletag.pubads());
    googletag.pubads().enableSingleRequest();
    googletag.enableServices();
  });
</script>

<!-- /5748/scm.main -->
<div id='r1301'>
	<script>
	  googletag.cmd.push(function() { googletag.display('r1301'); });
	</script>
	</div>
```
