Amazon's A9 algorithm decides which products appear on page 1. It cares about two things: relevance (does this listing match what the buyer typed?) and performance (does this listing convert when shown?). Here's how to optimize for both.
Amazon allows up to 200 characters in a title. Use them.
Formula: [Brand] + [Primary keyword] + [Key feature 1] + [Key feature 2] + [Size/Quantity] + [Use case]
Example: "NatureBrew Organic Green Tea | 100% Whole Leaf | Antioxidant Rich | 50 Tea Bags | For Hot & Iced Tea"
What this does: "Organic Green Tea" is the primary keyword — placed early for A9 weight. "Whole Leaf" and "Antioxidant Rich" are features buyers filter by. "50 Tea Bags" answers quantity before the buyer has to click. "Hot & Iced Tea" captures two distinct use-case searches.
Amazon buyers scan bullet points in 3 seconds. Each bullet point should do one thing:
Wrong: "High quality materials used in manufacturing"
Right: "FOOD-SAFE STAINLESS STEEL — Double-walled 18/8 steel keeps coffee hot for 6 hours and cold for 12. BPA-free. Dishwasher-safe lid."
Amazon gives you 250 bytes of backend search terms (invisible to buyers, fully indexed by A9). Rules: Do not repeat words already in your title. No commas — just spaces between terms. Include common misspellings, plural/singular variations, and synonym terms.
Listara builds the complete Amazon listing package: Title (200 characters, structured for A9), 5 bullet points (benefit-led, keyword-rich), product description, and backend keyword suggestions. Input your product details. Get a ready-to-paste listing in under 15 seconds.
