   • What's the primary business goal for SEO?
   • What keywords/topics are priorities?

2. Current State

   • Any known issues or concerns?
   • Current organic traffic level?
   • Recent changes or migrations?

3. Scope

   • Full site audit or specific pages?
   • Technical + on-page, or one focus area?
   • Access to Search Console / analytics?
