Despite TikTok Shop, despite Rufus AI, despite Sponsored Display invading every pixel — Amazon is still a search engine first. 81% of clicks land on page 1, and 35% of those go to the first organic position alone. The brands ranking up there are not the ones running the biggest ad budgets — they're the ones with the cleanest keyword infrastructure underneath.
What A10 actually weighs in 2025
Amazon's A10 algorithm has moved beyond simple keyword matching. The current ranking signals, in rough order of weight:
- Conversion rate — does your listing actually sell when clicked?
- Sales velocity — recent sales weighted more than historical
- Price competitiveness — vs. similar ASINs in the category
- Stock availability — out-of-stock kills rank fast, recovery takes weeks
- Seller authority — account health, on-time delivery, return rate
- External traffic — clicks from Google, social, or paid ads outside Amazon
Keyword optimization is still essential, but it's the entry ticket — not the deciding factor. If your listing has the right keywords but doesn't convert, you'll still drop.
Short tail vs long tail — when each wins
Short-tail keywords (1-2 words like "bluetooth speaker") have massive traffic and brutal competition. Long-tail keywords (3+ words like "waterproof bluetooth speaker for shower") have less volume but much higher purchase intent — and much higher conversion. Our rule: build the catalog around long-tail first, then layer short-tail as authority grows.
The backend keyword field most brands waste
Backend keywords (Search Terms in Seller Central) are invisible to buyers but ranked by Amazon. Most brands either leave them blank or stuff them with junk. The right use:
- Common misspellings of your product or category
- Spanish translations if your market includes Hispanic buyers
- Synonyms and related terms not in your title
- Use cases ("for camping", "gift for dad")
What NOT to put: competitor brand names (TOS violation), repeated keywords already in the title, or commas (Amazon parses spaces — commas are wasted characters).
The PPC → organic flywheel
Sponsored Products campaigns don't just drive paid sales — they feed organic rank. When a customer clicks your ad and converts on a specific keyword, that conversion signals A10 that you deserve organic visibility for that term. Strategic use: identify keywords where you rank position 10-25 organically, push PPC hard, and watch organic rank climb over 4-6 weeks.
Keyword strategy on Amazon isn't about ranking for everything. It's about owning the 20 terms that actually buy from you.
