Understanding Amazon's A9/A10 Algorithm

Amazon's search algorithm determines which products appear when a shopper searches. Unlike Google, Amazon's algorithm is laser-focused on one thing: purchase likelihood.

The key ranking factors:

  • —Relevance — does your listing match the search query?
  • —Performance — click-through rate, conversion rate, sales velocity
  • —Customer satisfaction — reviews, returns, seller metrics

Title Structure That Ranks

Amazon allows up to 200 characters for product titles. Here's the optimal structure:

`` Brand + Product + Key Feature + Material + Size/Count + Use Case `

Good example:

EcoChop Premium Bamboo Cutting Board Set — 3-Piece with Deep Juice Grooves, Anti-Slip Feet, BPA-Free, Knife-Friendly Surface for Home Kitchen

Bad example:

Cutting Board

Title Rules

  • —Front-load your highest-volume keywords
  • —Include 3-5 key features
  • —Don't repeat words unnecessarily
  • —Capitalize the first letter of each word (title case)
  • —Never use ALL CAPS for emphasis

Bullet Points That Convert

Amazon gives you 5 bullet points. Each should follow this formula:

` CAPS BENEFIT WORD: Feature explanation with benefit to customer ``

Example:

VERSATILE 3-PIECE SET: Includes Large (18x12"), Medium (14x10"), and Small (10x7") cutting boards for every kitchen need — from chopping vegetables to slicing meats.

Bullet Point Strategy

1. Bullet 1 — Your #1 unique selling proposition 2. Bullet 2 — Materials/quality/safety 3. Bullet 3 — Problem it solves 4. Bullet 4 — Social proof / comparison 5. Bullet 5 — Guarantee / risk reversal

Backend Keywords

Backend search terms are invisible to shoppers but critical for discovery. Rules:

  • —250 bytes maximum (not characters)
  • —Never repeat words from your title or bullets
  • —Include misspellings, Spanish translations, synonyms
  • —Exclude brand names, ASINs, subjective claims
