How the Amazon A10 algorithm works
Amazon's algorithm - now referred to as A10 - has one job: show shoppers the products they're most likely to buy. That means ranking is driven by conversion signals, not just keyword matching. A listing that gets clicked but doesn't sell will fall in rankings. A listing that converts consistently will rise, even with lower ad spend.
The key signals A10 weighs are: click-through rate from search results, conversion rate on the listing page, sales velocity (how many units you're selling per day), review count and rating, and seller authority (account age, metrics, return rate). Understanding this tells you where to focus your energy.
Keyword research the right way
Most sellers stuff their listings with whatever comes up on a keyword tool. The result is a title that reads like a bot wrote it and confuses both the algorithm and the buyer. Keyword strategy on Amazon requires thinking in layers.
Optimising your product listing
Your listing is your salesperson. It needs to do three things simultaneously: rank in search (keyword relevance), get clicked (compelling title and main image), and convert (everything else).
Title formula that works
Brand name + Primary keyword + Key feature + Size/Colour/Quantity + Secondary benefit. Keep it under 200 characters and human-readable. If a real customer would stumble reading it aloud, rewrite it.
Bullet points that sell
- Start each bullet with a benefit in caps, then support it with a feature (benefit first, always)
- Address the top five objections a buyer has before purchasing this category of product
- Include specific numbers where possible: "covers up to 500 sq ft" beats "large coverage area"
- Don't use all five bullets for features - use at least two for reassurance (warranty, compatibility, what's in the box)
Read your listing as a first-time buyer who knows nothing about your product or your brand. Does it answer every question they'd have? Does it make them feel confident enough to click Add to Cart? If there's any hesitation, the listing needs work.
Images that convert browsers into buyers
On mobile - which is where 70%+ of Amazon India purchases happen - your main image and your price are virtually all a buyer sees before deciding to click. The main image is your single most important ranking asset because it drives click-through rate, which drives sales velocity, which drives ranking.
- Main image: white background, product fills 85%+ of the frame, no text or props - follow Amazon's rules exactly or risk suppression
- Lifestyle image (image 2): product in use, in context, showing the buyer what their life looks like with it
- Infographic image (images 3–5): key features with overlaid text, dimensions, what's in the box, comparison charts
- Video (if eligible): a 30–60 second product demo increases conversion rate by an average of 9% based on Amazon's own data
Getting reviews systematically
Reviews are one of the highest-weighted ranking signals on Amazon. A product with 50 reviews at 4.5★ will almost always outrank a newer product with better content and no reviews. Building review velocity early is critical.
- Enroll in Amazon's Vine programme for new product launches (if eligible) - you send 30 units to Amazon reviewers in exchange for honest reviews
- Use the "Request a Review" button in Seller Central within 5–30 days of delivery for every order
- Automate review requests using tools like FeedbackWhiz or Helium 10's Follow-Up tool
- Never incentivise reviews - Amazon's detection is sophisticated and account suspension is a real risk
- Respond to negative reviews publicly within 24 hours - it signals seller engagement and can reverse a 1-star over time
A product moving from 3 reviews to 15 reviews typically sees a 30–50% increase in conversion rate. The first 15 reviews are the hardest and most valuable. Everything you do in the first 60 days should be focused on getting those reviews.
Using Sponsored Products to accelerate ranking
Amazon Sponsored Products aren't just for visibility - they generate real sales, which generate real ranking signals. Paid sales count toward organic ranking. Done right, your ad spend is buying ranking, not just clicks.
The launch sequence
Account health and the signals Amazon watches
Ranking isn't just about your listing - it's about your seller account. Amazon suppresses listings from sellers with poor account health, and low-health accounts lose the Buy Box (which accounts for 80%+ of sales).
- Order Defect Rate must stay below 1% at all times - this is Amazon's most critical metric
- Late Shipment Rate must stay below 4% - use FBA to eliminate this risk entirely if you can
- Valid Tracking Rate must stay above 95% for non-FBA shipments
- Respond to all customer messages within 24 hours - including weekends and holidays
- Monitor the Account Health dashboard weekly, not monthly - problems compound fast
