Key Insights
Key Takeaway
Scotts and Milorganite are the two most mentioned lawn fertilizer brands in this measurement. Both appear in every response that named a brand at all. Their reach across the four engines is identical. Their standing as a first choice is not. Scotts holds a top three position on all four engines. Milorganite holds one on two of the four. Being named everywhere and being recommended first are different things, and this category separates them cleanly.
