Why is the UTM Tracking setup not working in my website created using WordPress?

Right click on your website and click Inspect .
Navigate to Elements if you are using Chrome, Edge, or Safari browser. If you are using Firefox browser, navigate to Inspector .
Search for the iframe tag containing the public URL of the form as shown.
Check if the public URL is in the following format:

src="https://forms.zohopublic.com/testing/form/ContactForm204/formperma/ThEJ9a4NotojZHxyN2cUWxSfGoVkO26JJ9JPhPDl9E" with src as the attribute as shown in the above image.

Otherwise,
Add  class="no-lazyload",  if you are using  Smush  plugin.
If you are using any other plugin, add the domain  zohopublic.com  in the Plugin settings to avoid lazyloading for Zoho Forms iframe.
If you are still unable to resolve the issue after following the above steps, add  class="skip-lazy".  Check with WordPress to remove lazyloading for iframe.
