This is very common with pixel tracking codes. The head section (<head>) does not accept any code that is <img>, <iframe>, and more. It normally only takes <link>, <script> and <meta>.
Solution
If you have to paste code that's not being saved in the head section, paste it in the header or in the body-end.html. To do so, follow these steps:
Placing code in the header:
- In the side panel, click Settings and then click Head HTML.
- Paste your code in the Head HTML section and click Save.
Consent management apps are not able to prevent code from running prior to consent when the code is placed in the header HTML. This is because Duda optimizes the structure and order of how content loads, based on performance best practices on the site. We place scripts and CMP banners lower on the page, in order to improve the performance of primary content. Because of this, it is recommended to place code in the body-end when using a consent management app.
Placing code in the body-end.html:
- Click the Developer Mode (
) icon in the navigation bar. - Click Site HTML/CSS.
- Select body-end.html.
- Past your code into the last line.
- Click Save.
