Amazon SEO 2025: Ranking Factors and Optimization Strategies
Current analysis of Amazon A9/A10 algorithm factors and practical tips for better rankings on Amazon.
The A10 Algorithm
Amazon uses the "A10" algorithm (the evolution of A9) for ranking. Unlike Google, the most important factors are heavily revenue-driven:
Absolute sales figures and velocity (sales per time)
Keyword placement in title, bullets, backend
Ratio of clicks to purchases
Number and average of reviews
FBA, Price, A+ Content, external traffic
Keyword Research for Amazon
Unlike Google, on Amazon you search for purchase-intent keywords:
Tools for Amazon Keyword Research
- Amazon Autocomplete: Type in your keyword and see what Amazon suggests
- Amazon's own search-term reports: Analyse competitors' keywords
- Amazon Brand Analytics: Official Amazon data (for Brand Registry sellers)
- Search Query Performance: Which keywords bring traffic to your listings?
Keyword Types
Head Keywords
Short, high volume, high competition
Long-Tail Keywords
Specific, lower volume, better conversion
Title Optimization
The title is the most important place for your keywords:
[Brand] + [Main Keyword] + [Most Important Feature] + [Secondary Keyword] + [Variant/Colour/Size]
Example
Optimizing Bullet Points
The 5 bullet points are your sales copy and keyword reservoir:
Backend Keywords
The hidden keywords that only Amazon sees:
- Maximum length: 250 bytes (approx. 250 characters without umlauts)
- No repetitions: Don't repeat keywords from the title
- Use synonyms: Alternative spellings, regional terms
- No competitor brands: This is against Amazon TOS
- Spaces instead of commas: Saves characters

Conversion Factors
A good ranking is useless without conversions. These factors influence your conversion rate:
Images
- At least 7 high-quality images
- Main image: product on a white background, filling 85% of the frame
- Infographics with dimensions and features
- Lifestyle images (product in use)
- At least 1 video (if possible)
Price
- Stay within the competitive range
- Win Buy Box (for arbitrage/wholesale)
- Coupons and deals for visibility
Reviews
- At least 15+ reviews for trust
- Aim for a 4+ star average
- Respond to negative reviews professionally
External Traffic (New Ranking Factor)
In 2025, Amazon weights external traffic more heavily than ever before. These are traffic sources from outside Amazon:
- • Instagram Shopping
- • TikTok Shop
- • Pinterest Pins
- • Google Shopping
- • SEO (blog articles)
- • Google Ads
- • Amazon Influencer Program
- • YouTube Reviews
- • Podcast sponsoring
- • Amazon Attribution
- • Brand Referral Bonus
- • Amazon Posts
Conclusion
Amazon SEO 2025 is a mix of keywords and performance. The most important takeaways:
- Sales are the #1 ranking factor – optimise for conversions, not just keywords
- Title = most important keyword position – place main keywords at the front
- Backend keywords for synonyms – no repetitions, no competitor brands
- External traffic is becoming more important – use Attribution for tracking
- Images and reviews for conversion – without conversion there's no sustainable ranking
