Great news! Your dashboard is expanding! Widgets for SEO reporting and Best Practices are being added to your Sites and Groups Overview dashboards.
Sites Overview Dashboard
Groups Overview Dashboard
Your SEO score is included in the overall score for Sites and Groups, but Best Practices is not.
Both SEO and Best practices checks can be turned off at the site-level if desired. This will also remove their scores from the site's Dashboard. These options have no affect on Group Dashboards where the site is part of the group.
