Publishing third-party ad codes on your ad server may be necessary for various scenarios. For example, if you have publishers/traffic but no advertisers, utilizing ad codes from third-party ad networks can be a viable option. Fortunately, Adserver.Online simplifies this process by providing a special HTML/JS banner.
What is third-party code?
Example of third-party code:
<iframe src="https://some-url" width="240" height="400"></iframe>
To ensure the proper functioning of the HTML/JS banner, it is crucial to avoid inserting HTML and BODY tags in the code field. The system will automatically add all necessary tags.
The logic behind HTML/JS banner is straightforward – it injects third-party code into a website's page. That's it.
However, there are two ways of how it can do that:
This is the default, safe, and recommended mode.
In this mode, the system creates an iframe within the target webpage and injects 3rd-party code. This ensures that the page code and the 3rd-party code do not interfere with each other. The 3rd-party code is contained in the iframe, preventing any potential damage to the page or vice versa.
IFrame container (strict)
This injection type works similarly to the previous one with one exception – it creates IFrame with a "sandbox" attribute. The value of the attribute is the following "allow-scripts allow-popups allow-forms".
The sandbox attribute enables extra restrictions for the content in the iframe.
You can use it when you don't trust the 3rd-party code and don't want to allow it to access your page content.
Note very old browsers may not support the sandbox feature.
In this mode, the system injects 3rd-party code directly into the target webpage. To work in this mode correctly, 3rd-party code must support asynchronous loading.
It's not always easy to understand whether ad code supports asynchronous loading or not. The following hints may help you:
- The easiest and most reliable way is to check it from the code documentation if it's available.
- If the code contains the string "document.write", it does NOT support asynchronous loading and will NOT work in "Direct injection" mode.
- If the code contains the string "async", it will work normally.
- If the code contains only the HTML tags IFRAME, IMG, A, and no SCRIPT tags, then it will work in Direct injection mode.
Direct injection (in-place)
This type might be useful for codes containing only a single SCRIPT tag. For example, <script src="https://example.com/tag.js"></script> and nothing else.
Also, you may try this type if no one of the others made your 3rd-party code work well.
In most cases, it's impossible to count clicks over 3rd-party codes due to technical limitations and browser policies.
The only chance to count clicks is if the 3rd-party code supports it explicitly via particular parameters. Learn more
The 3rd-party code is a black box. There are no technical ways to look into it to understand whether it displayed an ad or not. Hence, it's impossible to count impressions that happened inside a 3rd-party code with 100% accuracy.
That's why HTML/JS banner counts an impression every time it injects 3rd-party code into the target page. So the system will count an impression even if the 3rd-party code displays nothing.
