Custom channels allow you to track the performance of ad units. You design your own custom channels and use them to view the performance of your ad units in ways that are meaningful to you. You can create up to 500 custom channels for each of your AdSense products.

How you can use custom channels

Track a group of ad units

Here are a few examples of ways you can group and track ad units with custom channels:

• Ad sizes
• Location of ads on a page — left side vs. right side, embedded in content or above it
• Page topics — articles about sports vs. entertainment

Track ad units by custom channel ID

You can also track ad units by adding custom channel IDs to your ad unit code. For example, let's say you want to track how much you earn from your signed-in users versus your non-signed in users. You'd create two custom channels, then add the ID of the first custom channel to the ad units you show to your signed-in users and the ID of the second custom channel to the ad units you show to your non-signed in users. You can now compare the performance of these two custom channels in a custom channels report.

Example

Here's an example showing some ad unit code with the custom channel ID 1234 added to it:

<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-1234567890123456" crossorigin="anonymous"></script>

\<!-- signed_in_ad_unit -->

<ins class="adsbygoogle"

     style="display:block"

     data-ad-client="ca-pub-1234567890123456"

     data-ad-slot="0123456789"

     data-ad-format="auto"

     data-ad-channel="1234"

     data-full-width-responsive="true"></ins>

<script>

     (adsbygoogle = window.adsbygoogle || []).push({});

</script>

Note: When viewing custom channel reports, you might be viewing some impressions and clicks that have been tracked in multiple channels. If you add an ad unit to more than one custom channel or assign more than one custom channel to an ad unit, then clicks and impressions from that ad unit will be recorded for each of the custom channels.
