Relevancy remains the foundation of A9. Choose a primary keyword that exactly matches the main term shoppers use and place it at the beginning of your title. Next, add 2-3 secondary keywords that describe key features (size, colour, material) and user scenarios. Write bullet points that outline the five most important benefits-not just features-and ensure each bullet contains a relevant keyword. In your description, tell a story that covers all important specs and use cases; this longer section gives you room to include long‑tail phrases naturally.

Conversion rate is the second pillar. Amazon measures how many shoppers who view your page end up purchasing. To improve it, focus on professional imagery, clear value propositions and competitive pricing. Include multiple lifestyle images and infographics; show close‑ups of textures, included accessories and scale references. Use the first 80 characters of your bullet points to get to the point quickly-many shoppers only read the beginning. Offer variations (size, colour) through parent‑child listings to capture a broader audience without splitting reviews.

Customer satisfaction signals to A9 that your listing provides a great shopping experience. Keep your Order Defect Rate under 1 % by responding quickly to buyer messages and resolving issues proactively. Use FBA or SFP to ensure fast delivery and automatically handle returns. Encourage reviews by sending polite post‑purchase emails through Buyer‑Seller Messaging or using Amazon’s Request a Review button. Address negative feedback publicly and professionally; this shows transparency and may persuade onlookers to trust your brand.

Relevancy is more than keyword placement; it’s about matching shopper intent. Use keyword research tools to map queries to intent categories: informational (‘how to descale a coffee machine’), navigational (‘Cuisinart coffee maker’) and transactional (‘best programmable coffee maker under $100’). Build your content around transactional and high‑intent keywords to attract ready‑to‑buy shoppers. Place the primary intent term near the beginning of your title, weave secondary intents into bullet points and description, and reserve synonyms and alternate spellings for backend search terms. Check your indexing by searching your ASIN combined with your target keywords - if your product appears in the results, A9 has recognised the connection.

Beyond conversions, customer satisfaction is paramount. The Order Defect Rate (ODR) measures how many orders result in negative experiences (refunds, claims, negative feedback). Keep your ODR below 1 % by using FBA, responding to customer messages within 24 hours and proactively solving problems. Amazon also looks at Return Dissatisfaction Rate and Contact Response Time. Investing in customer service tools and standard operating procedures will pay dividends in your search positioning.

To truly decode A9, you need to look at data through the lens of Amazon’s business model. Amazon earns revenue when shoppers buy, not when they browse. This is why sales velocity and conversion rate carry more weight than raw keyword frequency. Analyse your Unit Session Percentage (USP) - the ratio of orders to sessions - to identify bottlenecks in your funnel. If your USP is below the category average, run promotions or adjust pricing to stimulate demand and improve your standing in the rankings.

Include terms such as ‘Amazon ranking factors’, ‘A9 algorithm guide’ and ‘boost Amazon ranking’ in your copy to target sellers researching the topic. Pair these with phrases like ‘increase conversion rate’, ‘improve click‑through rate’ and ‘higher sales velocity’ to align with high‑intent queries from business owners seeking performance improvements.

Think of A9 as a matchmaker. Its job isn’t to answer trivia-it’s to pair a shopper with the product they’re most likely to buy. Whereas Google asks “what page best answers this question?”, Amazon asks “what product will this person purchase?”. To make that decision, A9 processes mountains of data: every click, review, order and return influences the ranking.

At the heart of A9 is a simple goal: maximize Revenue Per Customer (RPC). The algorithm watches how listings convert shoppers into buyers, how often they’re returned or refunded, and how satisfied customers feel. It then sorts products accordingly.

The Three Pillars: Satisfaction, Conversion and Relevancy

Amazon’s ranking logic can be boiled down to three pillars:

  • Customer Satisfaction & Retention. This pillar measures how happy buyers are. Metrics like order defect rate, perfect order percentage and in‑stock rate factor heavily. Late shipments or a spike in returns will hurt your position.
  • Conversion Rate. A9 rewards products that turn browsing into buying. High sales velocity, competitive pricing, engaging images, answered questions and a steady stream of reviews all feed this pillar.
  • Relevancy. Before A9 can rank you, it has to know your listing matches the search. It looks at titles, bullet points, descriptions, backend search terms and category placement.

Supporting Characters: Eight Essential Ranking Factors

Beyond the pillars, A9 listens to a cast of supporting characters. These factors can make the difference between page one and obscurity:

  1. Keyword relevance. Use clear, natural language in your title, description, features and backend terms; avoid stuffing.
  2. Conversion rate & sales history. Monitor your unit session percentage to track how well traffic turns into orders.
  3. Reviews & ratings. Quantity and quality matter; encourage happy customers to leave feedback and address negatives quickly.
  4. Click‑through rate (CTR). Craft compelling titles and images that invite clicks.
  5. Seller performance. Fast shipping, responsive customer service and low order defect rates signal reliability.
  6. Prime eligibility. Fulfillment by Amazon (FBA) makes your product Prime‑eligible and often boosts rankings.
  7. Sales velocity. The faster your product sells, the more Amazon believes it’s relevant.
  8. Inventory availability. Keep items in stock; A9 deprioritizes listings with frequent stockouts.

Mastering these elements is the art of Amazon SEO. In the next pages, we’ll explore how they intersect with AI‑driven search and how to weave them into a powerful story.

Finding the Right Keywords for A9

Effective keyword research combines broad terms that describe your category with specific, high‑intent phrases that signal purchase intent. Start by using keyword tools to identify high‑volume search queries and competitor terms. Mix these with long‑tail combinations such as “shock‑absorbent phone case with built‑in card holder” so you capture buyers who know exactly what they want. Place your primary keyword at the beginning of your title, weave secondary phrases naturally into bullet points and descriptions, and avoid stuffing irrelevant terms.

Leveraging Backend Search Terms

The hidden “Search Terms” field in Seller Central is a powerful way to include synonyms, misspellings and competitor names without cluttering your listing. Think of backend keywords as your SEO safety net. Fill the allotted space with relevant phrases not already used in your title or bullets, focusing on long‑tail variations and alternate descriptors. Avoid repeating words, punctuation and filler terms like “and” or “with,” and stay within the character limit. Use tools like Reverse ASIN Lookup to discover keywords your competitors rank for and Amazon Autocomplete to find trending search phrases. Regularly check your indexing by searching your ASIN with these terms to ensure Amazon registers them.

  • Use all available space but never exceed the character limit or include punctuation.
  • Avoid duplicating keywords already in your visible copy.
  • Include synonyms, abbreviations, misspellings and competitor names.
  • Prioritize long‑tail phrases with high relevance and low competition.
  • Check indexing periodically using your product’s ASIN.

Keyword Research & Listing Optimization

To maximize your chances of appearing on that prized first page, invest in meticulous keyword research. Tools like Helium 10 and Jungle Scout help you identify high‑volume, low‑competition terms. Aim for a mix of broad and long‑tail keywords: broad terms capture volume, while specific phrases deliver higher conversion rates. Craft concise, informative, keyword‑rich titles and ensure each word serves a purpose. Use bullet points and descriptions to highlight benefits and secondary keywords. Finally, don’t neglect your backend search terms-these hidden fields are an SEO safety net for synonyms and variations.

These best practices align your listing with A9’s pillars and set the stage for the generative tools we explore next.

Work the Search Terms field: Amazon allows around 249 bytes of hidden keywords. Use that real estate wisely by including synonyms, alternative spellings, materials and abbreviations that shoppers might use. Don’t repeat what’s already in your title or bullets and avoid subjective claims or temporary statements. Choose the most accurate category and sub‑category for your product and fill in technical specifications like size, weight and material-these details improve discoverability and help A9 understand exactly what you’re selling.

Visuals and availability matter: Upload at least a 1,000 × 1,000 px main image so customers can zoom in, and include lifestyle shots to showcase the product in use. Stay in stock and maintain a perfect order rate; stock‑outs or high defect rates signal unreliability and push you down the rankings.
