Specify the details of the creative under the following headings:


  • The ID is automatically generated by Adhese after the creative is saved.
  • Give the creative a meaningful and clear name in the Name field. A distinct name makes it easy to recognize the creative in the next step when the creative is attached to a booking. 
  • In the Format field, click the Select format link. This opens the List of formats modal window. Select the right format with the correct dimensions from the list and click the Save button.
  • The Last updated field denotes when the creative was updated for the last time.

Target URLs

  • In the Select target field, determine the target URL or the URL of the landing page. Click the show more URLs link to add multiple target URLs to the creative.

    You may omit http:// from the target URL, as Adhese will automatically add http:// to the URL. If the target URL is over a secure connection, you must add https:// to the target URL.


  • Each campaign, booking and creative is monitored, and reports are available in the interface of Adhese. It is also possible to let a third party monitor a creative. The client needs to provide a tracking URL. This URL is inserted in the Tracking URL field. For more information about the tracking URL, refer to Third-party tracking.


  • The Extra field 1 and 2 input fields are custom input fields depending on the chosen format and template. These fields are used for adding extra functions, such as adding a background colour to a wallpaper ad.

Upload files

A format needs to be selected before you can upload an HTML5 creative.

To upload an HTML5 creative, click the Main file button. You need to choose a correct .zip HTML5 creative file. For details, see the HTML5 Creative file section below. 

While a .zip file is uploaded, Adhese checks several possible issues, such as the file size and correct implementation of the clickTag.

If something is wrong, the .zip file is not uploaded, and Adhese gives an error notification. 

If you are convinced that an error notification is not justified, you can disregard it by simply checking the Ignore errors (only for me) box under the Alternative creative section and upload the file again. 

Next to the .zip file, you can upload up to five additional files. This enables you to upload HTML5 creatives with additional material, such as a wallpaper. 

Note that if you do not provide a clickTag and check Ignore errors, your clicks will not be tracked by Adhese.

Click the Save button after the .zip file is uploaded.

HTML5 Creative file

The HTML5 creative file is a .zip file that defines the creative or advertisement. You can either receive such a .zip file from the advertiser or prepare it by yourself.

To create it by yourself, make sure:

  • The .zip file contains at least an index.htm or index.html file or another unique .htm or .html file. This file will be used as the starting point for the HTML5 ad.
    Make sure to use only alphanumeric characters, dots, and underscores in the filename. Other characters might cause problems when Adhese processes the file!
  • The main .html file contains a clickTag. Adhese relies on it to track clicks correctly.
  • The main .html file relatively refers to all code and assets. This means that all links in the HTML5 creative, such as the link to an image within the ad, need to use a relative path, for example,/graphics/ad-image.png or <img src="/graphics/ad-image.png">. This enables the ad to be self-contained and, therefore, to run independently or to render without a network connection. External libraries and web fonts can be an exception to this guideline. 

Some additional guidelines:

  • There are no specific rules for the folder structure inside the .zip file. You can organize all files in different subfolders or within the root folder.
  • The number of files should be kept to a minimum because each different file results in a single request that affects the web page's performance where the ad is being loaded. 

All links in the HTML5 creative, such as the link to an image within the ad, need to use a relative path, e.g. /graphics/ad-image.png or <img src="/graphics/ad-image.png">. This enables the advertisement to run independently. External libraries and web fonts can be an exception to this guideline.

The use of Adhese macros, such as [adheseReplace:xx] or <ADHESE_X>, from within the HTML5 file is not possible. An Adhese value will not replace these macros.


To let Adhese measure the clicks of the banner, some extra work is required:
  1. We require a JavaScript variable to be present in the code. This variable has to be named clickTag in order to be picked up.
    The value of the clickTag variable needs to be a string literal within single quotes:

    <a id="clickThroughBtn" target='_new' href="">Register click</a>
    	var clickTag = '';
    	document.querySelector('#clickThroughBtn').href = clickTag;
    </script> ...
  2. This variable should be placed in the main HTML file as this is the only file that will be parsed.
  3. An URL of the landing page will be provided in the Adhese UI. Together with our click tracker, this URL will be assigned to the clickTag variable once the banner is uploaded.
  4. Make sure to make use of this variable when implementing the click-through logic!

Some banners make use of more than one landing page. Because of this, we allow the implementation of up to 9 different landing page URL's, each with its own click tracker.
To make use of this option, you can define several clickTag variables in the following manner:

   var clickTag = '';
   var clickTag2 = '';
   var clickTag3 = '';

All clicks will be counted together to calculate the total amount of clicks on a specific banner. However, in the more detailed reports, you will be able to look up the clicks per URL.

Adhese detects the clickTag in compressed code. Compressed code is used to reduce file sizes by removing line breaks, tabs, and double spaces.

Even when the clickTag variable is present in the code and the click URL is correctly filled in by Adhese, it is still possible that Adhese won't measure clicks.
If this is the case, you will have to contact the supplier of the HTML5 file as it might be possible that the clickTag variable is not used or is overwritten.


You have the option to save the booking by clicking the Save button. When clicking the arrow next to this button, several saving options become available in a drop-down menu:

More files

If a creative consists of more than one file, e.g. a background image and a video clip, you can add these individual files to the creative. After a format is selected, a new section becomes available: More files. This section enables you to add up to six files to a creative. Click More files... to expand this section. Five buttons appear that make it possible for you to upload more files.

Additional creatives

After a format is selected, you can upload the main file of the HTML5 creative. You have to save the main creative before you can upload the additional creative(s). An additional creative is a variant of the main creative, e.g., images with different dimensions for different platforms. For more information about how to upload additional creatives, refer to Additional creatives.


After the file is uploaded, a visual preview of the creative appears. Check if there are no errors. 

You can switch between the actual size of the creative and its thumbnail. To show the exact size, click the [ show actual size ] link or click the [ show thumbnail ] link to show the thumbnail. 

If the HTML5 contains an action script with an HTTP request, various browsers may block the preview because the Adhese interface connects through HTTPS. It depends on the kind of browser what should be done to preview the creative:

  • In Google Chrome, click the shield button situated on the right of the browser's address bar. Click the Load unsafe script button to enable the preview of the HTML5 creative.

  • In Mozilla Firefox, click the shield button situated on the left of the browser's address bar. In the drop-down menu, choose Disable protection for now.

Link to live preview

You can preview the creative in its context after the file is uploaded and saved. Use this feature to check if there are no errors (see the next paragraph). We recommend checking the live preview in more than one browser. No impressions will be counted while previewing a creative in the live-preview mode. For more information about live previewing a creative, refer to Live preview a creative.

A link to the preview will only be available if a booked position has the same dimensions as the format selected for the creative.

The URL of the live preview can be copied and forwarded to the advertiser to check if the creative is shown how the advertiser wants the creative to be shown.

Checking the URL of the uploaded creative

After you have uploaded and saved the HTML5 creative, the URL of the landing page needs to be verified. To verify the URL:

  1. Do one of the following:
    • Click on the preview of the creative in the Adhese interface, or
    • Click on the creative in the live-preview mode.

    A new page is opened. If the URL is correct, the following message appears:

    Creative link OK, click below to check if the landings page is correct.
    Adhese succeeded in parsing the link you clicked. Click tracking is now active for his creative.  

    If the above message does not appear, Adhese does not measure any clicks.

  2. Click the link in the message to check if the URL goes to the actual landing page.

    If the preview does not click through, the HTML5 creative may not contain the clickTAG. For information about how to add a clickTAG correctly, refer to the above Upload files paragraph.
