Optimise listings for conversion and content for helpfulness

Key takeaways

  • Amazon ranks products it expects to sell; Google ranks pages it expects to be helpful.
  • Amazon PPC sales can support organic rank; Google Ads do not affect organic results.
  • Most Amazon-first brands should fix listings first, then use Google to feed tagged traffic to Amazon.

Amazon judges conversion; Google judges helpfulness.

The core difference: buying intent versus information

People search Amazon when they are close to buying. Queries are short and product-focused, and Amazon's job is to show products that will sell and satisfy the customer. People search Google at every stage, from research to purchase, and Google's job is to return the most helpful page. That is why an Amazon listing is judged mainly on whether it converts, while a web page is judged on whether it answers the question well.

What each search engine ranks

Amazon ranks product detail pages, one ASIN at a time, inside its own catalogue. Google ranks billions of web pages, including product pages, articles, videos and, often, Amazon listings themselves. Your Amazon listing can show up in both places, which is one reason clear titles and descriptions matter beyond Amazon.

Ranking signals compared

Amazon does not publish its ranking weights, and neither does Google, but the broad signals are well known. On Amazon, relevance gets a product indexed and performance decides position. On Google, relevance and quality of content, links from other sites and page experience all play a part. See our Amazon A10 algorithm guide for more on Amazon's side.

  • Amazon: keyword relevance in title, Item Highlights, bullets and backend terms
  • Amazon: sales history, conversion rate, click-through, price, reviews, stock
  • Google: content relevance and depth
  • Google: links from other trusted sites
  • Google: page experience, mobile usability and speed
  • Both: matching the searcher's intent

Keywords work differently

On Amazon, keywords need to be in an indexed field, and there are hard limits. Since July 27, 2026, titles are capped at 75 characters for every category except media, with a 125-character Item Highlights field and backend search terms for hidden synonyms. On Google there is no hidden keyword field that helps ranking, and stuffing words into a page does more harm than good. Google rewards natural language that covers a topic fully. Our Amazon backend keywords guide covers Amazon's hidden field. Research tools also differ: Amazon keyword data comes from Brand Analytics, search term reports and Amazon-specific tools, while Google data comes from Search Console and web keyword tools, and the same phrase can have very different demand on each.

Paid ads affect them differently

On Amazon, Sponsored Products sales count as sales, and sellers widely see that sales history supports organic rank. On Google, paying for ads does not change organic ranking at all. That makes Amazon PPC part of an Amazon SEO plan, while Google Ads and Google SEO are separate efforts.

How fast results come

Amazon can move quickly: a better main image or a price change can lift click-through and conversion within days, and a launch with ad support can rank in weeks for less competitive terms. Google SEO is slower. New content often takes months to earn links and trust. Plan budgets with that difference in mind. It also means Amazon results can fall just as fast: a stockout or a run of poor reviews can cost rank in days, while a well-linked Google page tends to hold its position for longer.

AI search on both platforms

Both engines now answer questions with AI. Amazon says Rufus was renamed Alexa for Shopping on May 13, 2026, and its answers draw on listings, reviews and questions. Google shows AI overviews above many results. On both, clear, factual, specific content is more likely to be used. Our AI search optimisation service covers this for brands. For Amazon, that means answering common buyer questions directly in bullets and A+ Content. For Google, it means pages that state facts plainly, cite sources and show who wrote them.

How to split effort between Amazon SEO and Google SEO

If most of your revenue is on Amazon, put listing optimisation first, because it affects every sale. Then use Google to capture research searches and send buyers to Amazon with Attribution tags, which can earn the Brand Referral Bonus. See our guide to driving external traffic to Amazon.

  • Amazon first: titles, Item Highlights, images, backend terms, reviews
  • Google second: buying guides, comparisons and brand pages
  • Connect them: tagged links from Google to Amazon
  • Measure both: Amazon Attribution plus Search Console
