How to make custom native tower ads

Tower ads are horizontal banner ads that float and stay over the page as the viewer scrolls. You can use native templates to create tower ad items that are tailored to your needs.

A sample tower ad

This feature requires the Enhanced Ads add-on. For more information on adding add-ons to your subscription, read How to change your subscription.

In this guide, we're going to create a simple tower ad using a custom native ad template. This type of native template has all the code - HTML, JavaScript, and style element - necessary to display the ad properly.

If you'd rather sanitize the template and have only HTML inside it, you should make your tower ad using a styled native ad template instead. For more information on the differences between custom native ads and styled native ads, read About native ad templates.

Templates for custom native ad items are not compatible with styled native ad items, and vice-versa.

You will learn:

  1. How to create a template for a custom tower ad. You can customize the sample code to fit your needs.
  2. How to create a custom tower ad item once you have a custom tower template.

This template will require the user to provide the URL to where the image creative is hosted when creating the tower ad item.

  1. Click Native Ad Templates in the left navigation menu to go to the Templates section.
  2. Click Add Native Ad Template in the Native Ad Templates table. The New Native Template window will appear.
  3. Click Custom Rendering/API. The New Native Ad Template page will appear.

  1. Name the template then add an image URL variable for the image that will be in the ad. In our sample code, we called this variable ImageURL.

You can save variables and use them in other templates. After adding a variable, click on the three dots at the far right of the variable fields then click Save Variable as Template. To use a saved variable, click Add Saved Variable while creating a native template.
  1. Enter the code in the HTML Template (Custom Rendering) field, then click Save Changes.

Here's the code we used in our example:

<!DOCTYPE html>
<html lang="en">
            .tower-container {
                width: 250px;
                height: 500px;
                position: fixed;
                bottom: auto;
                top: 250px;
                left: 1rem;

            .tower-image {
                max-height: 100%;
                max-width: 100%;
                object-fit: cover;
                margin: 0;
                padding: 0;
                border: 0;

            .tower-close-button-container {
                position: absolute;
                top: 5px;
                right: 5px;
                cursor: pointer;

            .tower-close-button {
                width: 21px;
                text-align: center;
                display: inline-block;
                color: #ffffff;
                font-size: 18px;
                background: #000000;
                border-radius: 21px;
                user-select: none;
        <div class="tower-container">
            <a target="_blank" href="[TRACKING_LINK]">
                <img class="tower-image" src="[%ImageURL%]">
            <div class="tower-close-button-container">
                <span class="tower-close-button" onclick="closeButton()">×</span>
            function closeButton() {
                document.querySelector('.tower-container').style.display = 'none';

You can now use this template to create a custom tower ad item.
