Amazon listing optimization means making a product page match what shoppers search for and then persuading them to buy: the right keywords in the title, item highlights, bullets and backend search terms, plus images, A plus content, price and stock that let the listing win the Featured Offer. Ranking and conversion are one job, not two.
Two things changed in 2026. Amazon capped non-media titles at 75 characters from 27 July 2026 and added a separate indexed Item Highlights field. And Rufus, Amazon’s AI shopping assistant, now answers questions in natural language, so listings have to read like an answer as well as a keyword string. Everything below was checked on 12 September 2026, so confirm limits in Seller Central before a bulk edit.
Key takeaways
- Non-media product titles are capped at 75 characters including spaces, with a new 125 character Item Highlights field below the title.
- Backend search terms are limited by bytes, not characters: 249 bytes in the United States. Going over can de-index the whole field.
- Amazon has said item name and item highlights are both search inputs, with neither prioritised.
- Rufus and intent-based ranking reward listings that state the use case, not just the specification.
- Since July 2026 the Featured Offer is driven mainly by price, availability, delivery speed and prep quality.
- Measure with Search Query Performance: impression, click and purchase share by query.
How does Amazon search work in 2026?
Amazon search still starts with keyword matching: your listing must contain a term to rank for it. On top of that sits an intent layer that reads what a shopper is trying to achieve, plus Rufus, a conversational assistant that answers shopping questions. Relevance, click-through rate, conversion rate and sales velocity then order the results.
Three gates. Indexing: if the words are not in your title, item highlights, bullets, description or backend terms, you cannot appear. Intent: Amazon research on its COSMO system describes mining common sense relationships from shopper behaviour, so a listing that explains purpose and context can surface for queries it does not match word for word. Performance: listings that get clicked and bought move up.
Rufus sits in front of all of this, pulling from listing copy, A plus content, reviews and question-and-answer content to answer shoppers in plain language. Amazon has not published the weighting of these signals, and much of what circulates in seller forums is inference. The safe direction: describe outcomes and context in natural sentences, keep keyword coverage complete, and keep conversion high.
What are the Amazon listing character limits now?
Non-media titles are limited to 75 characters including spaces. Item Highlights allows 125 characters and is indexed for search. Backend search terms are capped at 249 bytes in the United States. Product descriptions allow 2,000 characters of plain text. Bullets have a recommended 255 character style limit.
| Field | Limit | Indexed for search |
|---|---|---|
| Title (non-media) | 75 characters | Yes, heavily |
| Item Highlights | 125 characters | Yes |
| Bullet points | 255 characters each, 5 bullets | Partly |
| Backend search terms | 249 bytes (US) | Yes |
| A plus content | Varies by module | No, but read by shoppers and assistants |
The title change is the big one. Amazon began rewriting over-length titles with its own generated versions, and brand-registered sellers get a review window before changes go live while others do not. Details and the enforcement timeline are set out in this breakdown of the 75 character title limit.
How do you write an Amazon title in 75 characters?
Lead with the brand, then the core product noun, then the one attribute a buyer filters on, then size or count. Cut repeated keywords, promotional words and anything a shopper would not say aloud. Move the secondary terms you lose into Item Highlights and backend search terms so indexing does not suffer.
A 75 character title has room for roughly eight to ten words, so every word has to earn its place.
- Keep: brand, product type, defining attribute, size or quantity.
- Cut: repeated words, “best”, “premium”, symbols, all caps, seller name.
- Move: secondary use cases into Item Highlights.
Write three candidates, then check each against real queries in your Search Query Performance report. If a high-volume query cannot match your title, it belongs in Item Highlights.
How should bullet points and the description be written?
Use five bullets, each one leading with a short benefit phrase then a plain sentence that explains it. Cover fit, use case, material, care and what is in the box. Answer the objections your one-star and three-star reviews raise. Keep it readable on a phone, where most shoppers see only the first two bullets.
Bullets do two jobs: they give the crawler natural language and give Rufus material to quote. A simple pattern works, a benefit phrase then one sentence of proof. For example, “Fits standard 8 inch pans: the silicone rim seals to any pan between 7.5 and 8.5 inches, so steam stays in.”
The description is plain text only. Restate use cases in full sentences and add whatever reduces returns: sizing, compatibility, care. Returns are expensive, and the returns processing fee inside Amazon’s FBA fee structure makes vague copy a direct cost.
How do backend search terms work?
Backend search terms are hidden keywords in the listing’s Generic Keyword field, capped at 249 bytes in the United States. Bytes, not characters: accented and non-Latin characters cost more than one byte. Exceeding the cap can silently de-index every term in the field, so measure before you save.
- No commas needed. Single spaces between words are enough.
- Do not repeat words already in the title, item highlights or bullets.
- Include misspellings, abbreviations, regional words and Spanish terms your buyers use.
- Never include competitor brand names, claims or temporary terms like “sale”.
Byte limits differ by marketplace, so a term list that fits in the United States may not fit elsewhere. The country by country limits are laid out in this reference on Amazon listing character limits.
Do images, video and A plus content improve conversion?
Yes. Images are the first thing a shopper judges, and the gallery usually decides click-through and return rate before a word is read. A plus content, available through Brand Registry, adds comparison charts, lifestyle imagery and brand story modules that raise conversion and reduce size and fit returns.
A working gallery: clean main image on white, a scale shot with a familiar object, a use-in-context shot, a labelled feature diagram, a size or compatibility chart, a box contents shot, and a short video. A plus content sits under the buy box and is one of the brand-exclusive benefits Amazon lists for Brand Registry. Use its comparison chart module to sell up into your own range rather than to argue with competitors.
How do price and the Featured Offer affect your listing?
The Featured Offer, still widely called the Buy Box, is the offer attached to the Add to Cart button. Since a July 2026 change, Amazon no longer uses seller performance as a standalone eligibility gate. Price, availability, delivery speed and prep quality now do most of the work.
Without the Featured Offer your ads and organic rank are worth far less, because clicks land on a page selling someone else’s offer. Three rules follow.
- Never go out of stock on a ranked ASIN. Availability is a direct input, and stockouts also trigger the low-inventory-level fee.
- Keep price competitive against the same item elsewhere, including your own other channels.
- Fix prep and packaging defects, because they show up as damage, returns and slower delivery promises.
The eligibility change and its rollout are summarised in this note on the Featured Offer eligibility gate.
What does a before and after listing look like?
A rewrite usually shortens the title, moves the lost keywords to Item Highlights and backend terms, turns keyword-stuffed bullets into plain sentences that answer objections, and adds a scale image plus a comparison chart. The keyword coverage stays the same. The page just becomes readable by people and by assistants.
Example: a pour over coffee kettle.
| Element | Before | After |
|---|---|---|
| Title | BrandName Premium Stainless Steel Pour Over Coffee Kettle Gooseneck Spout Tea Pot 1.0L Best for Drip Coffee Barista Gift (119 characters) | BrandName Gooseneck Pour Over Coffee Kettle, Stainless Steel, 1 Liter (69 characters) |
| Item Highlights | Empty | Precision spout for drip coffee and loose leaf tea. Works on gas, electric and induction hobs. |
| First bullet | PREMIUM QUALITY STAINLESS STEEL KETTLE POUR OVER COFFEE KETTLE GOOSENECK KETTLE | Slow, controlled pour: the narrow gooseneck spout lets you wet the grounds evenly, so extraction stays consistent cup after cup. |
| Images | 4 studio shots on white | 7 assets: white main, scale shot, in-use shot, feature diagram, hob compatibility chart, box contents, 20 second video |
| Backend terms | Repeats of title words | Non-duplicated terms only: swan neck, drip kettle, barista kettle, hervidor, misspellings |
| A plus content | None | Comparison chart across 3 sizes, care instructions module |
How do you measure Amazon listing performance?
Use the Search Query Performance report in Brand Analytics. It shows, for each search query, total impressions, clicks and purchases on Amazon and your brand’s share of each. Falling impression share means a keyword problem. Falling click share means images or price. Falling purchase share means the page or the offer.
| Symptom | Likely cause | First fix |
|---|---|---|
| Low impression share | Not indexed or weak relevance | Add the query to title, item highlights or backend terms |
| Good impressions, low click share | Main image, price or rating | Test a new main image and check price against rivals |
| Good clicks, low purchase share | Page fails to convince, or no Featured Offer | Rewrite bullets around objections, add A plus content, check stock |

What this means for marketers and creators
What this means for marketers and creators
For marketers, listing work is the cheapest performance lever you own. A listing that converts at 12 percent instead of 8 percent cuts your effective cost per acquisition by a third with no change in bids. Fix the page before you argue about budget, and use Search Query Performance to decide which keywords deserve paid support. The terms behind these metrics are defined in our digital media planning glossary.
For creators selling products, your advantage is proof. You already have video of the product in use, real customer questions and honest comparisons. Turn that into the gallery, the A plus modules and the bullets, then send external traffic to a page that is ready for it. Tag those links so you can tell which platform sent buyers, using our free UTM campaign builder.
What are the most common listing mistakes?
The usual errors are keyword stuffing that now breaks the title rule, duplicate terms wasting backend bytes, galleries with no scale shot, bullets written for a crawler rather than a buyer, and editing five things at once so no one can tell what worked.
- Ignoring the 75 character rule. Leave it and Amazon rewrites the title for you.
- Duplicating keywords across fields. Extra copies waste the 249 bytes you have.
- No scale reference in the gallery. Size surprise is the top driver of avoidable returns.
- Writing bullets in capitals. They read badly on mobile and give assistants nothing quotable.
- Changing everything at once. One change, two weeks, then read the report.
Frequently asked questions
What is the Amazon title character limit in 2026?
Non-media product titles are limited to 75 characters including spaces, applied from 27 July 2026. Media categories keep a longer limit. Titles above the cap are gradually replaced by Amazon generated versions, with a review window for brand-registered sellers.
How many backend search terms can I add?
The Generic Keyword field is capped by bytes rather than characters, at 249 bytes in the United States. Other marketplaces use different limits. Standard Latin letters cost one byte, accented and non-Latin characters cost more, and exceeding the cap can stop the whole field being indexed.
Does Rufus change how I should write listings?
It changes the style more than the keywords. Rufus answers shopper questions in natural language using listing copy, A plus content and reviews, so full sentences that state who a product suits, what problem it solves and its limits give the assistant something to quote. Keep keyword coverage complete as well.
How long does it take for listing changes to affect ranking?
Indexing updates usually show within a few days, but ranking reacts to performance, so allow two to four weeks before judging a change. Read impression, click and purchase share in Search Query Performance rather than daily sales, which are too noisy to interpret.
Do I need Brand Registry to optimise a listing?
No, but it helps. Brand Registry adds brand-exclusive features Amazon lists, including A plus content, Brand Stores, Sponsored Brands, Vine and Brand Analytics. Without it you can still fix titles, bullets, backend terms, images and price, which covers most of the available gain.
