Thanks for reaching out. If your not seeing ads placed on your site there could be a number of reasons. Here in Site Kit support we’re limited to the snippet placement via Site Kit, and the dashboards within the plugin. From checking your site I can see that the plugin has inserted the AdSense Auto ads snippet and I don’t see any modification to that snippet.
As the snippet has been placed via Site Kit have you tried reaching out to the AdSense support team at the official Help Center?
Before doing so I’d be happy to confirm your account and site is approved on the AdSense platform if you want to share your Site Health information here or privately via this form. You can also check this yourself by visiting your AdSense account or by checking your own Site Health information.
