The New Rules of Amazon SEO: What Rufus and COSMO Mean for Ambitious Ecommerce Brands
The New Rules of Amazon SEO: What Rufus and COSMO Mean for Ambitious Ecommerce Brands
Amazon is constantly evolving. But the biggest evolution on Amazon we’re experiencing is not a subtle tweak to the algorithm. It’s a wholesale shift in how shoppers search, how products are shown, and how sales are won.
If your team is still focused on keyword stuffing and ticking boxes, you’re not just behind. You’re invisible.
Meet COSMO and Rufus- Amazon’s newest AI systems that are transforming the marketplace from a keyword-based search engine to a fully conversational, intent-led buying experience.
COSMO and Rufus: Are They the Same?
Let’s clear this up: COSMO and Rufus are two separate AI systems-but they work together.
▪️ COSMO sits behind the scenes, acting like Amazon’s intelligent brain. It analyses customer behaviour, product listings, reviews, and Q&A to figure out what products actually mean in real life. Not just what they are, but why someone would buy them.
▪️ Rufus is what the shopper sees. It’s Amazon’s conversational assistant, answering real-time questions like “What’s a calming product for an anxious rescue dog?” Rufus relies on COSMO’s data to give smart, relevant answers.
Together, they change everything about how products are ranked and discovered.
What This Means for Sellers
This isn’t about theory. It’s about your listings performing-or not.
Traditional SEO strategies are becoming obsolete. COSMO doesn’t care how many keywords you’ve jammed into the title. It cares about context. About clarity. About why someone would buy your product.
And Rufus? It’s the friendly face of that logic-guiding customers to exactly the right product, using plain language and smart comparisons.
COSMO: The AI Behind the Curtain
COSMO (short for Common Sense Knowledge System) is designed to infer what customers actually want-even when they don’t say it directly.
Instead of matching search terms to titles, it looks at patterns:
▪️ What do people actually buy after searching for certain things?
▪️ What types of questions do people ask in reviews?
▪️ Which images help customers understand the product best?
COSMO uses this data to recommend products that solve real-life problems. It’s not just reading your copy-it’s judging it. And if it doesn’t make sense to a human, it won’t make sense to COSMO.
Rufus: Amazon’s Chat-Based Concierge
Rufus is the interface. It’s what shoppers interact with when they type a full question into the search bar like, “What’s the best bed for a senior Labrador with arthritis?”
Rufus isn’t pulling results from keywords-it’s pulling understanding from COSMO.
▪️ It offers product comparisons.
▪️ It answers pre-purchase questions.
▪️ It suggests gifts, kits, and bundles based on customer needs.
And it’s already live. 10% of US shoppers are actively using Rufus today-a milestone it hit faster than Alexa ever did.
So, What Do You Need to Do?
Let’s keep this simple:
Tell stories, not specs – Use plain, human-first language. Explain who your product is for, when they’d use it, and why it’s useful. “Perfect for nervous cats during firework season.”
Think like a customer – What would a dog owner really ask? “Will this slow feeder help my puppy stop gulping food?” Answer that.
Make your images work harder – Show lifestyle, use, and context. A dog in the harness on a walk-not just flat lays.
Seed your Q&A with gold – Preload thoughtful, use-case based questions and answers. “Is this calming spray safe for kittens?”
Don’t ignore your attributes – COSMO uses every dropdown, detail and filter. Incomplete data = missed sales.
