Two Search Engines, Two Completely Different Games

One of the most common questions from ecommerce sellers is whether Amazon relies on Google's SEO system, or whether ranking well on Google automatically improves Amazon performance. The short answer is no. Amazon operates its own independent search engine with its own ranking algorithm, its own index, and its own definition of success. Google is a discovery engine designed to answer questions and route people to the best available information. Amazon is a purchase engine designed to maximise revenue per search. Those objectives produce fundamentally different ranking logic, and confusing the two is one of the most expensive mistakes an online seller can make.

How We at AAMAX.CO Can Help You Win on Both Search Engines

At AAMAX.CO, we are a full service digital marketing company providing web development, digital marketing, and SEO services worldwide, and we work with ecommerce brands that need visibility across the entire buyer journey rather than a single channel. That means optimising Amazon listings for conversion-driven ranking factors while simultaneously building the Google presence that captures shoppers earlier, before they ever open a marketplace. We handle keyword research for both systems, build content that ranks for comparison and research queries, and connect the two so marketplace revenue and owned-site revenue reinforce each other. If you are relying on a marketplace alone, our SEO services can open a channel you currently do not control but should.

How Amazon's Ranking System Actually Works

Amazon's search algorithm is built around the likelihood that a search results in a sale. Historically known internally by the codename A9 and later evolved further, the system weighs relevance and performance together. Relevance comes from your title, backend search terms, bullet points, brand, and product attributes. Performance comes from conversion rate, sales velocity, click-through rate, price competitiveness, availability, review count and rating, fulfilment method, and return rate. A listing that converts strongly will outrank a listing with better copy but weaker sales. There is no equivalent of backlinks, no domain authority, and no concept of topical authority across a catalogue. Amazon does not care how many sites link to your product page. It cares whether shoppers buy.

How Google's System Differs

Google ranks pages for informational, navigational, commercial, and transactional intent across the entire web. It relies heavily on links as votes of confidence, evaluates topical expertise and trustworthiness, considers page experience and speed, and interprets queries semantically rather than as literal keyword matches. Most importantly, Google serves the whole research journey. Someone comparing options, reading reviews, or learning about a product category is a Google user long before they become an Amazon buyer. That earlier stage is where brands build preference, and it is entirely invisible to a marketplace-only strategy.

So Does Amazon Depend on Google?

Not for ranking, but very much for traffic. A substantial share of Amazon's visitors arrive from Google searches. Amazon product and category pages rank prominently for enormous numbers of commercial queries, and Amazon invests heavily in paid search as well. In that sense, Amazon is one of the largest beneficiaries of Google's organic and paid ecosystem on the internet. But the relationship runs one way. Google sends people to Amazon; Google does not determine which product Amazon shows them once they arrive. Your Amazon ranking is decided entirely inside Amazon.

What This Means for Your Optimisation Strategy

Because the two systems reward different things, they require different work. On Amazon, focus on conversion mechanics: a title that leads with the primary keyword and core attributes, images that sell without needing to be read, bullet points that answer objections, competitive pricing, reliable stock, fast fulfilment, and a deliberate review-generation process. Keyword research should come from Amazon's own data and marketplace tools, not from general web search volume, because shoppers phrase queries differently inside a store than they do on a search engine.

Building the Google Layer Around Your Products

On Google, the opportunity is everything Amazon cannot host. Buying guides, comparisons, use-case content, technical explanations, and category education all rank on Google and all influence purchase decisions. Your own ecommerce site can also rank for the same product queries Amazon competes on, and every sale made there carries a far better margin, gives you the customer relationship, and builds an asset that no marketplace policy change can take away. Structured data, fast page performance, clean architecture, and genuine content depth are the tools that make this work.

The Dependency Risk of Marketplace-Only Selling

Sellers who build exclusively on Amazon rent their entire business from a platform that also competes with them, controls their pricing environment, owns the customer data, and can change the rules without notice. A single listing suspension, category restriction, or algorithm shift can erase revenue overnight. Diversifying into organic search on your own domain is not a vanity project; it is risk management. The brands that survive marketplace turbulence are the ones that spent the good years building demand they own.

Using Each Channel for What It Does Best

The strongest ecommerce strategies treat Amazon and Google as complementary rather than competing. Use Google to capture research-stage demand, build brand familiarity, and drive traffic to owned properties with better margins. Use Amazon to convert shoppers who are already in buying mode and trust the platform's logistics. Let branded search demand generated by your content work improve your marketplace performance, since branded searches on Amazon tend to convert at exceptionally high rates. Increasingly, that discovery layer extends into AI answer engines too, which is why GEO services are becoming a core part of ecommerce visibility rather than an experiment.

Measuring Performance Correctly

Because the systems are separate, measure them separately and then look at the interaction. Track Amazon keyword rank, conversion rate, session-to-order ratio, and advertising cost of sale inside the marketplace. Track impressions, clicks, position, and assisted conversions in organic search. Then watch for the connection: rising branded search volume, growing direct traffic, and improving marketplace conversion on branded terms are all evidence that your Google work is feeding your Amazon results.

The Bottom Line

Amazon does not run off Google's SEO, and optimising for one will not automatically deliver the other. Amazon rewards sales performance; Google rewards relevance, authority, and experience. But Amazon absolutely depends on Google for a large share of its incoming traffic, which tells you something important: the discovery layer is where purchase decisions begin. Own that layer for your own brand and you stop competing for a slot inside someone else's store and start owning the demand that fills it. A coordinated digital marketing strategy across both channels is what turns that idea into revenue.
