Catalog snapshot is United States. Dual-score: rankability first, business second. Playbook only after the SERP.
Does this seed lead to low-hanging fruit?
Two DR < 20 sites rank, volume is healthy, but .edu and publisher domains sit beside them. You can rank a tool. You cannot look sloppy.

The dosage calculator that shows the work — dimensional analysis on screen — then sells NCLEX-style practice. Not a clinical decision tool.
They fail dosage tests, not because of nursing, because of the math setup.
📍 r/nursing, r/StudentNurse, TikTok study accounts, Discord cohorts
MDCalc is for clinicians. Students need the units cancelled on screen.
→ Animated unit cancellation + 200 practice items
Exam season converts. Keep clinical disclaimers loud.
Education-only. No patient identifiers. No 'use at bedside' copy.
Win the click with the worked example, not a 400-word definition.
