Fescue and bermuda are two different products, and two different searches

Lawn care shoppers do not search for fertilizer. They search for what they have and when they have a problem with it — fescue overseeding, bermuda in July, zoysia in a cold zone — because the right product depends entirely on grass type, climate zone and the month. The brand's listings said “all-purpose lawn fertilizer”, which is the one description that matches none of those searches.

The consequence was not only invisibility. An all-purpose message sells cool-season products to warm-season lawns, and the resulting reviews are furious and specific: the customer applied the product correctly and their lawn suffered because it was the wrong product for their grass. The hero listing sat at 3.9 on a formula that works very well on the lawns it was designed for.

We let each product say which lawn it is for.

• A product-to-grass matrix — every formula assessed against grass types and hardiness zones, with honest exclusions written down.
• Grass type in the title and first bullet, which is the fastest way a shopper disqualifies a product they should not buy.
• Application timing by zone given as a simple calendar in the image stack, since the same product is right in April in one zone and wrong in another.
• Campaigns rebuilt around grass-type and zone language, where competition is lower and the shopper has already stated their situation.

Sessions grew to 81k a month and revenue grew 95%.

Ranking keywords carrying a grass-type term went from 60 to 900 — and that is the whole of it, since the brand now appears in the searches this category actually runs. The rating recovery from 3.9 to 4.2 came from the same change working in reverse: telling a shopper with bermuda that this product is for cool-season grass loses a sale and prevents a one-star review, and there were more of those reviews than there were lost sales.
