We don't have an ads integration, but this is something we're looking at adding in the future.
Ad services such as Google AdSense often require the site owner to add code before the <body> tags to verify the site is eligible to display ads.
<body> </body>
Since Universe is a no-code website builder, there is currently no way for us to edit this code for you to enable ads on your website. The Code Block allows you to insert iframe code on your site, but unfortunately does not allow you to edit the overall code of the site.
As of now, we are unaware of an ad provider that integrates without editing the overall code of the website.
