How to set up AdSense Multiplex Ads in WordPress

Over the past few years, Google has expanded the AdSense ad formats. The Multiplex ad format is the latest. It is available for manual injection and AdSense Auto ads.

In this tutorial, you’ll learn how to create Multiplex ads in your AdSense account and embed them on your website using Advanced Ads.

What are Multiplex ads?

Multiplex ads are not an entirely new ad format but rather a further development of the Matched Content ad units.

The Matched Content ads were native. Placed below the content, it recommended more of your articles to keep users longer on your website and displayed relevant ads simultaneously. The result resembled the related articles blocks seen on many websites.

This ad unit was only available to specific publishers. They had to have a lot of content on their websites, including images, so that AdSense could build diverse blocks from them. Also, publishers needed a minimum amount of traffic to select this format.

In contrast, Multiplex Ads are available to all publishers.

Google has decided to stop supporting the Matched Content ad format from March 2022. Instead, AdSense automatically converts these ads into Multiplex ads now.

All in all, this ad format is similar to the Matched Content ad unit as they contain multiple ads in a single block.

However, these blocks will no longer use editorial content from the publisher’s website.

To use Multiplex ads on your website, you must first create an ad of this type in your Google AdSense account.

Follow the steps below to generate the code for a Multiplex ad in your AdSense account.

Customize Multiplex ads

While creating your Multiplex ad, you will see a preview of the ad throughout. This preview will give you an idea of how the ad will look later on your website.

Ad size

Should your ad be horizontal or vertical? You can also set the ad dimensions in the Ad size section on this settings page.

Here, you can choose responsive ads, which automatically adapt to the available space of the containers on your website. Alternatively, you can set a fixed size, e.g., a vertical Multiplex ad unit with 300x800px.

Now you may wonder how to ensure that such fixed-sized ads appear in the correct size on all devices. You can solve this problem by embedding your AdSense ads with Advanced Ads.

The best way to target it to the appropriate devices is using the Browser Width or the Device condition of Advanced Ads.

Ad style

In the Ad style section, you can adjust the font, the font color, and the background color of the ads to the design of your website. If you don’t make any changes, your ads will have the typical AdSense layout.

When you have given your ad a title and completed the layout settings, enter a name for the ad unit at the top left of the screen. Afterward, click the “Create” button.

After clicking the button, a popup with the ad code will open. Copy this code to your clipboard.

Advanced layout options for Multiplex ads

The Advanced Ads Responsive add-on comes with the option to customize the layout and size of Multiplex ads. Those options are not available through the AdSense backend.

This way, you can dig deeper into the layout and change the arrangement of text and images in your ads.

For example, you can arrange images and text side by side, use the image above the text, text only, blocks as cards, etc.

Different styles of Multiplex ads

AdSense explicitly allows these customizations. You can find the related option in the Ad Parameters meta box under Layout and set the style you want.

Furthermore, you can precisely define the number of rows and columns on desktop and mobile to adapt the display dimension to different devices.

Multiplex ads on AMP pages

The Responsive add-on can automatically convert your Multiplex ads into the appropriate AMP format. So you can use it on this specific page format.

You can choose between an automatic conversion or set up another size through the additional options.

You can now publish the ad if you do not want to make more adjustments to the ads, e.g., set up specific margins or more refined targeting.

Choose a Placement and auto-inject the ad

Then, you can assign this ad to an existing placement or create a new one.

Proven positions for this ad type are the Sidebar Widget placement and the After Content placement. But you can also use Multiplex ads on other positions on your website or insert them manually via shortcode.

Advanced Ads offers you numerous placements for this purpose.

From now on, Google can also show Multiplex ads on your website.

How to track Multiplex ads

You can analyze the performance of your Multiplex ads through your AdSense account. We recommend using AdSense statistics for this.

Navigate to AdSense > Reports and choose “Ad formats” from the provided default reports.

Now, you can see the key figures like earnings, impressions, impression RPM, active view, or clicks sorted by the different AdSense ad formats.

If you have connected Advanced Ads to your AdSense account, then you can view the performance of a specific Multiplex ad in your backend. Just edit the ad unit and check the AdSense Earnings meta box.

In addition, you can also record the clicks, impressions, and CTR values of these ads with the Advanced Ads Tracking add-on

A use case for enabling the Advanced Ads tracking could be that you have connected your tracking to Google Analytics. Thereby, you can learn more about the visitors that click on your AdSense ads and how they behave on your website.
