The dashboard gives you an overview of all your connected sites: number of publications, health score, breakdown by category (structure, completeness, quality, SEO), a list of your sites with their status, and your recent content.
Right after connecting a site, click "Refresh all": without this sync, wp2ai has no information yet about its content. This is a mandatory step to get started, before you can explore your content, your alerts, or write with your AI assistant.
The site selector at the top of the menu lets you switch to a detailed view of a specific site, with its own SEO breakdown (indexed, custom, auto-generated, no SEO content) and its own alerts.
