How to make custom native floor ads

In online advertising, a floor ad (aka adhesion ad) is a banner ad (a horizontal rectangular ad) that appears and sticks to the top or the bottom of the user's window. You can use native templates to create floor ad items that are tailored to your needs.

A sample adhesion or floor ad

In this guide, we're going to create a simple floor 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 floor 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 floor ad. You can customize the sample code to fit your needs.
  2. How to create a custom floor ad item once you have a custom floor ad template.

How to create a custom floor ad template

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

Selecting a native template type

  1. Name the template then add an image URL variable for the image that will be in the ad. In our sample code, we named this variable ImageURL.
  2. Enter the code in the HTML Template (Custom Rendering) field, then click Save Changes.

Creating a custom native floor ad template

Here's the code we used in our example:

<!DOCTYPE html>
<html lang="en">
            .floor-container {
                position: fixed;
                bottom: 0;
                left: 0;
                width: 100%;
                background-color: rgba(0, 0, 0, 0.25);

            .floor-image-container {
                position: relative;
                width: 728px;
                height: 90px;
                margin: 0 auto;

            .floor-image {
                position: absolute;
                top: 0;
                left: 0;
                width: 728px;
                height: 90px;

            .floor-close-button-container {
                position: absolute;
                top: 3px;
                right: 3px;
                cursor: pointer;

            .floor-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="floor-container">
            <div class="floor-image-container">
                <a target="_blank" href="[TRACKING_LINK]" class="floor-image">
                    <img src="[%ImageURL%]">
                <div class="floor-close-button-container">
                    <span class="floor-close-button" onclick="closeButton()">×</span>
            function closeButton() {
                document.querySelector('.floor-container').style.display = 'none';

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