Competitive Amazon SEO Strategy: MECE Keyword Selection and Product Content Optimization
To increase sales on Amazon, simply listing products is not enough. Like Google, Amazon also has its own search algorithm, and Amazon SEO measures aimed at "being displayed at the top of search results" are indispensable. However, unlike Google, Amazon's algorithm (commonly known as A10, evolved from the former A9) places the greatest weight on "whether the product actually sells (CVR and sales performance)." In this article, we systematically explain the essence of Amazon SEO measures for new managers.

1. The Core of Amazon A10 Algorithm: The Importance of CVR and Sales Performance
Amazon's A10 algorithm rewards products that convert searchers into buyers. Understanding this purchase-intent focus is the key to effective SEO strategy.
The A10 algorithm evaluates products on multiple axes including "sales velocity," "CVR (conversion rate)," "relevance of search terms," and "seller authority." Unlike Google, which measures content quality through backlinks and dwell time, Amazon's algorithm is designed to prioritize products that actually sell. Therefore, keyword optimization alone is insufficient — unless the product page converts browsers into buyers, search rankings will not improve.
2. MECE Keyword Selection: Deconstructing Search Intent in 3 Layers
Categorize keywords into: brand terms, category terms, feature terms, competitor terms, and long-tail variations. Each keyword should serve a distinct search intent.
When selecting keywords using the MECE approach, organize them into three layers: "Big Keywords" (high volume generic terms), "Middle Keywords" (category-specific terms with moderate volume), and "Long-tail Keywords" (specific multi-word phrases with high purchase intent). Each keyword should serve a distinct search intent without overlap, ensuring comprehensive coverage of how customers search for your product category.
- Big Keywords: Category names and general product names (e.g., coffee beans). High traffic volume but fierce competition.
- Mid/Long-Tail Keywords: Words that specify purpose or features (e.g., coffee beans light roast gift). Tend to have higher CVR.
- Peripheral/Benefit Keywords: Words that solve user problems (e.g., wake up refreshing drink). Effective for reaching potential customers.
3. Product Content (A+) Optimization and Improving Unit Session Rate
Even if search rankings improve, if the page users click through to is not appealing, it won't lead to sales. Product content (A+) should be designed with mobile user visibility as the top priority.
In particular, utilizing the "comparison table module" promotes upselling and cross-selling within your own products, serving as a powerful weapon to prevent exits. Additionally, while text within images is not indexed by Amazon's search, you can strengthen indexing by incorporating keywords into alt text (alternative text).
