Key Insights
Key Takeaway
The lawn fertilizer category has its tightest cross-model consensus yet in our dataset: Scotts and Milorganite both at 12-of-12 cross-prompt presence. This is the only category in our dataset where TWO brands have hit 12-of-12 simultaneously. Jonathan Green and The Andersons hold the premium tier across 3-4 models each. Notable W20 development: Gemini broke from consensus by surfacing Lesco 24-0-11 as #1 in both P1 and P3 — first time any model has ranked a brand above Scotts in this category across our 3-run history. Worth tracking next run to see if this is volatility or a Gemini-specific trajectory.
