My site’s metrics are Certified. Why is no badge appearing on my Site Overview page?

The badge will only appear on your Site Overview page if you are displaying at least one certified metric for your site. For example if you are displaying Certified Site Metrics for Where Visitors Go, Visitors by Country, Ranks, or Daily/Monthly Unique Visitors and Pageviews. If you choose to not display any of these certified metrics on your Site Overview page the Certified Badge will disappear.

You can find instructions for changing your site's Certified metrics display settings in this article: How do I publicly display or hide my Certified Site Metrics?
