Hi @womp, at the moment if the site is being iframed or embedded and the url you are trying to use is the webflow.io staging domain to show the site in Pardot, it will not work as the webflow.io sites are not allowed to be iframed or embedded. To remove the Webflow branding, the domain request need to go through our proxy servers.
If pardot try to link directly to the webflow.io domain, the branding tag will not be removed.
What may work is if you setup a subdomain like pardot.mysite.com, and add that custom domain to the site project: https://university.webflow.com/article/how-to-set-up-custom-domain-hosting-for-your-webflow-site
Then, try to link Pardot to the custom domain name, not the webflow.io staging hosting, which is not using SSL nor is it using regular hosting features. Only when the site is having a custom domain are hosting feature limits increased.
Do you have documentation on how you are trying to link with Pardot?
