Trigger on 'marketing plan', 'marketing strategy for next year', 'go-to-market roadmap', 'plan for Q3', 'we have no marketing plan', 'where should we spend next quarter'.

Trigger on 'content calendar', 'posting schedule', 'what should we post this month', 'editorial calendar', 'social media plan', 'we post randomly with no plan'. Also use when the user only says the team keeps running out of things to post.

Covers dropshipping ROAS and BE-ROAS. Trigger on 'why is CPA so high', 'my ads are not converting', 'ROAS dropped', 'we are burning budget', 'performance is bad this month', 'diagnose the funnel'.
