Amazon isn’t a storefront a seller controls — it’s a marketplace a seller is allowed to sell on, under Amazon’s rules, and that distinction changes what “SEO” actually means there. On a Shopify or Etsy store, bad SEO costs a seller traffic. On Amazon, a listing that breaks the rules can get suppressed, stripped of its Buy Box, or removed entirely — no warning email, no grace period. Getting found and staying compliant aren’t two separate projects. They’re the same project.
That’s the part most “Amazon SEO” advice skips. It’s all keywords and bullet points, with no mention of the policy layer that determines whether that keyword-optimized listing is even allowed to stay live.
Amazon SEO isn’t Google SEO with different keywords
Amazon’s search algorithm — long known as A9, now commonly called A10 among sellers — doesn’t rank pages on relevance the way Google does. It ranks products on purchase intent. BigCommerce’s breakdown of the A9 algorithm puts it plainly: Amazon weighs relevance factors like title and backend search terms alongside performance factors like conversion rate, price, availability, and sales history, because Amazon only makes money when a search actually ends in a sale. A perfectly keyword-stuffed title with weak conversion will lose to a plainer title that reliably closes.
That’s why the two halves of this — compliance and optimization — can’t be separated. A suppressed or policy-flagged listing has a conversion rate of zero, no matter how well the title is written.
The listing rules that get sellers flagged without meaning to
Amazon publishes its Product Detail Page Rules directly, and most violations aren’t attempts to game the system — they’re sellers writing listings the way they’d write them anywhere else on the internet. The rules that trip people up most often:
- No pricing, shipping, or promotional language in the listing itself. “Free shipping,” “Sale ends Friday,” or a strikethrough price belongs in the price/deal fields Amazon controls — not in the title, bullets, or description.
- No contact information or links off Amazon. Websites, emails, phone numbers, or social handles anywhere in the listing are a policy violation, not a growth hack.
- One detail page per product, not per seller. A new color, size, or material variation needs its own listing or a proper variation relationship — not a duplicated page competing against the original.
- No symbols or claims the listing can’t back up. Trademark symbols, unverified “#1 Best Seller” claims, and award mentions without a supporting date and awarding body all get flagged.
- Images have to show the actual product, on a pure white background for the main image, with the product filling roughly 85% of the frame — no lifestyle scenes, watermarks, or added text on the primary image.
- Titles have a hard character cap and a soft one. Amazon allows up to 200 characters depending on category, but titles that stay under roughly 80 characters read cleanly on the mobile screens where the majority of Amazon traffic actually happens.
None of these are obscure. They’re published, they’re enforced automatically in many cases, and a listing that violates them can lose its Buy Box eligibility or get pulled from search entirely while the seller is still wondering why traffic dropped.
Reviews are where sellers cross a line without noticing
The other place good intentions turn into suspensions is reviews. Amazon’s Anti-Manipulation Policy for Customer Reviews is explicit: any attempt to influence a review with money, discounts, free products, or a refund tied to leaving feedback is prohibited — even indirectly, even through a third-party service that markets itself as “review management.”
The practices that feel like normal customer outreach but cross this line:
- Offering a discount code, refund, or free replacement in exchange for a positive review, or for removing a negative one.
- Asking only customers who already seemed happy to leave a review, while ignoring the rest.
- Using a friend, employee, or family member’s account to review your own product — or a competitor’s.
- Routing review requests through off-Amazon channels specifically to avoid Amazon’s own request-a-review system.
Reviews are also a direct performance ranking input, which is exactly why the temptation to shortcut them exists. It’s also exactly why Amazon enforces this policy harder than almost any other one — a manipulated review doesn’t just break a rule, it corrupts the data the algorithm uses to decide who deserves visibility.
Check category restrictions before writing a single bullet point
Some categories — supplements, beauty, anything battery-powered, anything making a medical or safety claim — require approval before a listing can go live at all. Building out full copy and photography for a product, then discovering the category is gated, is a common and avoidable waste of a launch week. Amazon’s Category Eligibility tool in Seller Central checks this against a UPC or ASIN before any content work starts, and it should be the first step, not a step taken after something gets rejected.
Amazon SEO isn’t a set of writing tricks layered on top of a listing. It’s relevance and performance, built on top of a listing that was compliant from the first draft. Skip the second part and the first part never gets the chance to matter.
What actually moves visibility once a listing is compliant
With the rules handled, the levers that genuinely move a product up in Amazon search are narrower — and more mechanical — than most SEO advice suggests:
- Put the highest-intent keyword in the title, early. Amazon’s search match weighs title heavily, and a keyword buried at character 150 does far less work than one in the first 60.
- Use every backend search term field. These aren’t visible to shoppers, which is exactly why they’re where synonyms, alternate spellings, and use-case terms belong — without repeating what’s already in the title.
- Write bullets around the buying decision, not the spec sheet. Each bullet should answer a real hesitation a shopper has, in the order those hesitations actually come up.
- Keep price and availability competitive. These are direct performance-ranking inputs. A well-written listing that’s out of stock or priced far outside the category range still loses visibility.
- Treat the first 90 days after launch as a sales-velocity sprint. Early conversion rate and review velocity set the trajectory the algorithm keeps rewarding or ignoring for months afterward.
None of this replaces the compliance work above — it only starts paying off once that work is already done.
Amazon is rarely the only channel that matters
Most sellers running Amazon well are running it alongside Etsy, Shopify, or a wholesale channel, and the same discipline — clean titles, real photography, policy-safe copy — carries over even though every marketplace’s specific rules differ. The principles behind getting found on Etsy and the principles behind getting found on Amazon overlap more than they diverge; what changes is which platform’s rulebook applies.
Avezant’s multichannel expansion work handles exactly this — keeping listings, inventory, and compliance consistent across every channel a store sells on, instead of treating each marketplace as a separate project with its own risk of getting something wrong. If Amazon listings are underperforming and it’s not obvious whether it’s a keyword problem, a compliance problem, or both, a free audit will show exactly which one it is.
