Common Questions
Amazon's A10 algorithm prioritizes sales velocity and conversion rate over backlinks and content depth. High click-through-rate (CTR) and conversion from searches signal relevance. Reviews, pricing, and Prime eligibility matter more than traditional SEO factors. Amazon SEO is performance-driven—rankings improve when you sell more.
Reverse ASIN lookup shows all keywords a competitor ranks for. Enter their ASIN into tools like Helium 10 Cerebro, and you see 1,000+ keywords with their rank positions. This reveals their keyword strategy and opportunities you're missing. It's the fastest way to understand what's working in your niche.
Use 5-7 primary keywords in your title, 15-20 in bullet points, and 200+ in backend search terms. Amazon indexes listings for hundreds of keywords automatically through NLP, but explicit keyword placement in titles and bullets improves rankings. Focus on 20-30 high-value keywords.
Tools provide data and optimization recommendations, but rankings depend on sales velocity, conversion rate, and competition. Optimize listings with keyword tools, then drive traffic through PPC or external sources to generate sales. Sales momentum creates ranking improvements—keywords alone don't guarantee results.
Prioritize buyer-intent keywords over high-volume generic terms. "Nike running shoes men size 10" converts better than "shoes." Target 3-5 word long-tail keywords with 500-5,000 monthly searches. These have less competition and higher purchase intent than one-word high-volume terms.
