Amazon SEO services help your products show up when people search on Amazon. We cut titles to the new 75-character limit. We fill the 125-character Item Highlights field. We use the full 249 bytes of backend search terms. Then we answer real buyer questions in your bullets, so Amazon search and its shopping AI can match you to more buyers. Plans start at The audit before we start is free, and there is no setup fee. per listing.

Key facts

What we optimize on every listing

We work on every field Amazon lets a seller edit that search or shoppers read. Each field has its own limit, and most of the gains come from using that space well. The table shows the field, the 2026 limit and our job on it.

Field 2026 limit What we do
Title 75 characters, spaces included (from 27 Jul 2026, media excluded) Brand, product type, the top one or two terms, key spec
Item Highlights 125 characters Materials, use cases, the next most searched terms
Bullet points No new limit in 2026 One buyer question per bullet, with use, occasion and buyer named
Description No new limit in 2026 Plain answers to what reviews and Q&A ask
Backend search terms 249 bytes Synonyms, other spellings, Spanish terms in the US store, no repeats
Attributes Set by category template Fill every relevant attribute, since filters and AI read them
A+ Content Modules set by Amazon Comparison charts and use cases, see our A+ content copywriting service
Images No alt text a seller can edit Text on images that repeats key claims; we never bill for “image alt text”

That last row matters. Some agencies sell “image alt text” as a line item. Amazon gives sellers no field for it, so there is nothing to write.

If you need a listing built from scratch rather than rewritten, that is our Amazon listing creation service.

The 2026 title rule, and how we handle it

The biggest change this year sits in the title. From 27 July 2026, Amazon wants titles of 75 characters or less in every category except media. Titles longer than that get “updated to the AI recommendation gradually,” in Amazon’s words. The listing stays live, but Amazon’s AI writes the new title, not you.

Brand owners get 14 days to review a change. We watch that window for every client ASIN (Amazon’s product ID). If Amazon’s version drops a key term, we fix it first.

Amazon’s own SEO blog from September 2025 still lists a 200-character title limit. It is out of date. Many agency pages copied that figure and still use it.

A worked example: one long title split three ways

Here is a real-style listing for a made-up brand. The old title runs 199 characters. We split it into three parts, so no search term gets lost.

Part Text Characters
Before: title Northpeak Insulated Water Bottle 32 oz, Stainless Steel Double Wall Vacuum Flask with Straw Lid and Spout Lid, Leak Proof, BPA Free, Keeps Drinks Cold 24 Hours, for Gym, Hiking, Office, School, Black 199
After: title Northpeak Insulated Water Bottle, 32 oz Stainless Steel, Straw Lid, Black 73 of 75
After: Item Highlights Double wall vacuum keeps drinks cold 24 hours. Leak proof straw lid and spout lid. BPA free. For gym, hiking and office. 120 of 125

After, bullets (what moved there):

  • “School” goes into a bullet about kids and lunch bags, with the size that fits a backpack pocket.
  • “Vacuum flask” goes into the backend terms, since shoppers in some regions search that phrase.
  • “Keeps drinks cold” gets a bullet with the test detail behind the 24-hour claim.

The math is simple. 199 characters came in. 73 stay in the title, 120 move to Item Highlights, and the rest moves into bullets and backend terms. Nothing the shopper searches for gets dropped.

Amazon has not said in writing whether Item Highlights count for search. One third-party tool vendor says they do. We treat them as indexed, but we still place every key term in a field Amazon has confirmed. The full rule set is in our 2026 Amazon title rules guide.

How Amazon search and Rufus read your listing

A shorter title changes what Amazon’s systems see first. So the next question is what those systems read. Amazon has published more on this than most agency pages admit, and it has published less than they claim.

A9 and A10: what Amazon has actually said

Amazon’s SEO guide names no ranking algorithm at all. A9 was the name of an Amazon subsidiary, A9.com, set up in 2004. “A10” appears in no Amazon document we can find. It is a label from the seller tool industry.

Pages that promise to “beat the A10 algorithm” sell a name, not a method. We work from what Amazon has put in writing.

COSMO: why use cases and audiences matter

In May 2024, Amazon Science described COSMO, a knowledge graph built with large language models. It learns from what shoppers search and then buy. It links products to relations such as used_for_function, used_for_event and used_for_audience.

In plain words, Amazon tries to learn what a product is for, when people use it and who buys it. Amazon reported that COSMO data raised a relevance model’s score (macro F1) by 60% in one test.

So our bullets name the use, the event and the buyer in plain words. “Fits a car cup holder for long drives” gives COSMO a function and an event. “Size for kids ages 6 to 10” gives it an audience.

Rufus (Alexa for Shopping): what it reads

Rufus is Amazon’s shopping assistant. Amazon renamed it Alexa for Shopping on 13 May 2026, and Rufus still runs underneath. Amazon says Rufus is trained on “Amazon’s extensive product catalog, customer reviews, community Q&As, and information from across the web.”

That list tells you where to work. Your catalog data is the one part you write. Reviews and Q&A are shoppers talking about you.

Here is what we do with it:

  1. We pull every negative review and every Q&A question for the ASIN and its top rivals.
  2. We tag each question that the listing does not answer yet.
  3. We answer the top ones in bullets and A+ Content, in the words shoppers used.

When a shopper asks Alexa for Shopping “will this fit a car cup holder,” the answer should already sit in your catalog data.

Our process, week by week

The Rufus work and the title work both sit inside one process. It starts with data from your own account, not a guess from a tool.

Step What happens When
1. Audit We score each field against 2026 limits and flag suppressed or blocked items Week 1, free
2. Keyword research Brand Analytics and Search Query Performance first, then outside tools Week 1
3. Review and Q&A mining We list the questions your listing leaves open Week 1 to 2
4. Rewrite Title, Item Highlights, bullets, backend terms, attributes Week 2
5. Your approval and upload You sign off; we upload and log each change Week 2 to 3
6. Index check We search each key term to confirm the ASIN shows up A few days after upload
7. Monitor Rank, sessions and conversion rate against the baseline 30 days

Brand Analytics and Search Query Performance are Amazon reports for brand owners. They show real search terms and how shoppers moved from search to purchase. We trust those first-party numbers over any tool estimate. Our Amazon keyword research page explains the method. If you want to do it all yourself, start with our Amazon SEO guide and the tools we use.

Amazon publishes no timeline for rank changes. In the accounts we manage, we give each rewrite a full 30 days before we judge it. Stock outs, price changes and ads in that window all skew the read, so we note them in the report.

The byte rule most sellers miss

Once the research is done, some terms go into the backend. Here the limit is 249 bytes, not 249 characters. An Amazon moderator put it this way: “the length limit for generic keywords is 249 Bytes.”

In plain English letters, one character is one byte. Accented letters like é or ü use 2 bytes. Japanese and Chinese characters use 3 bytes each. That matters in the UK, EU and Japan stores, and for Spanish terms in the US store.

Search term Characters Bytes
water bottle 12 12
gourde réutilisée isotherme 27 29
水筒 保冷 5 13

The worked math: a German seller who counts 249 characters and writes “für” ten times goes 10 bytes over. A Japanese backend field holds only 83 characters (249 divided by 3). We check every backend field with a byte counter before upload.

Our own house rules for the backend: we leave out brand names and ASINs, skip words already in the title, and separate terms with spaces.

Proof: what we can show you

We only publish numbers we can back with a screen from Seller Central. Our strongest public proof today comes from ads, not organic rank. In our ACoS case study, ad cost of sales fell from 35% to 10% in six months. The Seller Central screenshot shows ACOS at 9.96%.

That matters for SEO because ads and listings share one detail page. A clearer listing converts more of the clicks you pay for.

Beyond that one case, the record is plain. We have worked on Amazon accounts since 2019, managed over $100M in sales and delivered 100+ projects. Buyers of our work left 300+ reviews at a 5.0 average across freelancing platforms.

[SEO case study: before and after sessions and organic rank for one ASIN, to add once the client approves the numbers.]

What Amazon SEO services cost

Price depends on how many listings you have and how much ongoing work you want. Most agencies hide their prices. Two publish them, and here they are next to ours.

Provider What you get Price
eStore Factory Title, 5 bullets, description, backend per product $99 per product
eStore Factory A+ Content / Premium A+ $199 / $499
WebFX Bronze Monthly Amazon SEO plan $1,875 setup + $1,350 a month
WebFX Silver Monthly Amazon SEO plan $3,875 setup + $2,825 a month
WebFX Gold Monthly Amazon SEO plan $6,025 setup + $4,775 a month
GrowEventure Per-listing rewrite The audit before we start is free, and there is no setup fee.
GrowEventure Monthly plan The audit before we start is free, and there is no setup fee.

Prices come from each firm’s own pricing page, checked 22 September 2026.

A worked cost example

Say you sell 10 ASINs. At $99 each, a one-time rewrite costs $990. The WebFX Bronze plan costs $1,875 plus 12 times $1,350 in year one. That comes to $18,075.

Now check payback. If a product earns $8 profit per unit, a $99 rewrite needs 13 extra sales to pay for itself (99 divided by 8 is 12.4). Run that sum with your own margin before you pick any provider.

A one-time rewrite suits a stable catalog. A monthly plan suits a brand that launches often or sells in many stores. For many brands, rank also depends on ads, which is our Amazon PPC management service.

Amazon SEO consultant, agency or do it yourself?

The price gap above mostly reflects who does the work. An Amazon SEO consultant is one person. An agency is a team. Doing it yourself costs time instead of fees.

Option Best for Watch out for
Do it yourself Under 5 ASINs, one store, time to learn Easy to miss the byte limit and the 14-day review window
Freelance consultant A one-time rewrite of a small catalog One person means gaps during leave, and less ads know-how
Agency Many ASINs, many stores, SEO and ads together Higher cost; check who actually writes your copy

Ask any Amazon SEO consultant or agency three things before you sign. Who writes the copy? Do they use your Brand Analytics data? Who owns the listing content if you leave?

When you should not hire us

Some sellers should keep their money for now. We would rather tell you that in the audit than bill you for work that cannot pay off.

  • You have one ASIN with no sales history and no stock plan. Copy cannot fix a product that runs out of stock. Sort stock and launch budget first.
  • Your listing is blocked by a policy issue. A suppressed listing does not show in search at all. Fix account health first, then rewrite.
  • You want a guaranteed rank. No honest provider can promise one. Amazon controls ranking and changes it without notice.
  • Your catalog is all media. Books, music and video sit outside the 75-character rule, so much of this page does not apply.

Our guarantee

These are the terms for every Amazon SEO client:

  • One named account manager who knows the account.
  • A written report every month covering what changed and why.
  • Every file, login and asset stays the client’s.
  • No lock-in, cancel any month, no notice period.
  • No setup fee, and the audit before starting is free.
  • If we miss the scope agreed in the first 30 days, that month is free.

We do not promise a ranking, a Buy Box share or a sales figure, because those sit with the platform and not with us. We promise the work, the reporting and the terms above, and all three go in the contract.

Frequently asked questions

What is Amazon SEO, and how is it different from Google SEO?

Amazon SEO is the work of getting a product found in Amazon search. Google SEO ranks web pages across the internet. Amazon ranks products inside one store, where sales and conversion count heavily. Amazon also has no backlinks, and its fields have strict limits, such as 75-character titles and 249 bytes of backend terms.

How much do Amazon SEO services cost?

Published prices run from $99 per product at eStore Factory to $4,775 a month at WebFX. WebFX also charges a setup fee of $1,875 to $6,025. Our own price is The audit before we start is free, and there is no setup fee., with no setup fee. Compare the cost with the profit per unit you need to earn it back.

What does an Amazon SEO consultant do?

A consultant finds the terms your buyers search, then rewrites your title, Item Highlights, bullets and backend fields to match. A good one works from Brand Analytics data, checks that each term gets indexed, and watches the 14-day review window. They also mine reviews and Q&A for questions your listing leaves unanswered.

How long does Amazon SEO take to work?

Expect to judge a rewrite after about 30 days, not 3. Amazon publishes no timeline. We confirm indexing a few days after upload, then track rank, sessions and conversion for a month. Stock outs, price changes and new ads during that month can blur the result, so note them.

Is the A9 or A10 algorithm real?

A9 was a real Amazon subsidiary, A9.com, founded in 2004. “A10” is not an Amazon term. It comes from the seller tool industry. Amazon’s own SEO guide names no algorithm. What Amazon has published is research, such as the COSMO knowledge graph that links products to uses and buyers.

How do I optimize for Rufus?

Answer the questions shoppers ask in your own catalog data. Amazon says Rufus, now Alexa for Shopping, reads the catalog, customer reviews, community Q&A and web sources. Only the catalog is yours to write. So read your reviews and Q&A, find the open questions, and answer them in bullets and A+ Content.

How long can an Amazon title be in 2026?

Titles can be 75 characters, spaces included, in every category except media. The rule started on 27 July 2026. Amazon also added Item Highlights, which hold 125 more characters. Titles over 75 characters get an AI rewrite over time, and brand owners have 14 days to review it.

Does PPC help organic rank?

Amazon has not published a direct link between ads and organic rank. Ads do bring clicks and sales to the same detail page. In our view, that sales history likely helps organic rank, but treat it as a working theory. A clear listing makes both ads and organic traffic convert better.
