How to Write an Effective Amazon Product Description

Amazon's search algorithm, known as A9, decides within milliseconds whether your product appears on page one or disappears into page fifty. Most sellers never learn how it works, and their listings quietly collect dust while competitors make the sales.

Writing a product description on Amazon is not simply typing out what your item does. It is a precise craft with hard rules - like the 80-character mobile title limit that cuts off anything extra on a phone screen, or the July 2021 ban on HTML formatting that broke thousands of listings overnight.

This guide walks you through the entire process, starting from zero. You will learn how to find the exact words real shoppers type into the Amazon search bar, and which professional tools make that research faster and more accurate.

From there, you will discover how to build a title that works on both desktop and mobile, and how to write five bullet points that lead with benefits rather than dry technical specs. Then comes the product description itself - a 2,000-character space where plain text and smart storytelling do the selling.

For sellers who qualify, the guide covers A+ Content, a visual upgrade that lets brand-registered sellers add high-resolution images, comparison charts, and branded layouts to their pages. Finally, you will learn how to fix the errors that hide listings from search results entirely, including error codes 90122 and 90117.

By the end, you will have everything you need to build a professional Amazon listing from scratch - one that ranks higher, reads clearly, and turns browsers into buyers.

Using The Amazon Search Bar For Research

Most paid keyword tools cost $50–$100 per month, but Amazon hands you the same raw data for free - right inside the search bar.

Every time a shopper types something into Amazon, the site records it. That data feeds the autocomplete feature - the dropdown list of suggestions that appears as you type. Those suggestions are not random. They reflect what real customers are actually searching for, ranked by popularity.

Before spending a penny on software, work through these steps first.

1. Type Your Product Category - Start broad. Type "yoga mat" or "dog water bottle" and stop before pressing enter. Watch the dropdown suggestions appear. Write down every suggestion you see.
2. Add Letters to Dig Deeper - Type your product followed by a space and then the letter "a", then "b", then "c". Each letter pulls up a fresh set of suggestions. This simple trick multiplies your keyword list fast.
3. Study the Top Results - Press enter and scan the first page. Pay close attention to products marked "Best Seller" or "Amazon's Choice" - these badges signal high sales volume and strong customer engagement. Their titles are a keyword goldmine.
4. Copy Competitor Titles - Open three or four top-ranked listings and read their titles carefully. Note the exact words and phrases they repeat. Sellers who earn those badges have already done the hard research for you.
5. Sort Your Terms by Length - Separate what you collected into two groups. Short-tail keywords are broad, one-to-two word phrases like "yoga mat." Long-tail keywords are specific, three-or-more word phrases like "non-slip yoga mat for beginners." Short-tail terms get more searches but face more competition. Long-tail terms attract buyers who already know what they want.

Honestly, most beginners skip the letter-by-letter trick and wonder why their list feels thin. That single step doubles the number of terms you find without any extra tools.

Once you have your list, group similar terms together. Synonyms matter here - one shopper searches "travel mug," another searches "insulated coffee cup." Both describe the same product, and your description needs to speak to both.

By the end of this process, you will have a solid primary keyword list built entirely from real Amazon search behaviour - no subscription required.

Choosing The Right Professional Keyword Tools

Sellers using dedicated keyword tools find keywords that manual Amazon searches simply miss, because these tools process millions of search queries at once. That gap between guessing and knowing is where sales are won or lost.

Building on the search bar method from the previous section, keyword research tools automate that process and go much deeper. They pull real search volume data, competition scores, and trend information - all in one place.

Two paid tools built specifically for Amazon are Helium 10 and Jungle Scout. Both are Amazon-specific, which means their data comes directly from Amazon's search engine, not Google.

Helium 10 is the most popular choice for serious Amazon sellers. Its "Cerebro" feature lets you type in a competitor's product and see every keyword that product ranks for - a fast way to find terms you would never think of yourself.

Free options exist too. The SEOChat Keyword Suggest Tool searches Amazon, Google, Bing, and YouTube at the same time, making it a solid starting point when you are on a tight budget.

SEMrush is another paid option, but it is Google-focused rather than Amazon-focused. Use it to spot broader search trends, then cross-check those terms with an Amazon-specific tool before committing to them.

Keyword Tool automates the research process by pulling hundreds of keyword suggestions from a single seed term. It saves hours compared to typing variations manually into the search bar.

Tool	Cost	Platform Focus	Best For
Helium 10	Paid	Amazon	Deep competitor keyword research
Jungle Scout	Paid	Amazon	Product and keyword tracking
SEOChat Keyword Suggest	Free	Amazon, Google, Bing, YouTube	Initial brainstorming, zero budget
SEMrush	Paid	Google	Broad search trend research
Keyword Tool	Paid	Multi-platform	Automated bulk keyword generation

A practical approach is to start free with SEOChat to build your initial keyword list, then run your top candidates through Helium 10 to verify real Amazon search volume before writing a single word of your listing.

Once your keyword list is solid, every word earns its place - especially in your product title, where character limits are tight and mobile screens cut off anything that does not fit.

Mastering The 80-Character Mobile Limit

Amazon's 80-character mobile truncation rule cuts your title at exactly 80 characters on most smartphone screens, hiding everything after that point. Most shoppers never tap to see the full title, so whatever lands past character 80 is invisible to them.

Your full title can run up to 200 characters, and Amazon's A9 algorithm reads every single one of those characters. But the first 80 are the only ones your mobile buyer actually sees before deciding to click or scroll past.

Put your primary keyword right at the start of the title. Placing it in the first few words means it survives the mobile cut and signals relevance to the algorithm at the same time - two wins from one decision.

After your primary keyword, pack in the core product attributes: brand name, size, colour, and material. A title like "BrandName Stainless Steel Water Bottle 32oz Insulated Black" hits all four attributes and sits comfortably inside 60 characters.

Honestly, most beginners waste their first 80 characters on filler words like "Premium" or "Professional" that add nothing. A shopper searching for a water bottle does not need to be told it is premium - they need to know the size and material.

Amazon also bans promotional phrases entirely from titles. Phrases like "free shipping" or "100% quality guaranteed" will get your listing suppressed, meaning Amazon hides it from search results completely. Skip them.

Excessive special characters carry the same risk. One or two hyphens to separate attributes are fine, but strings of symbols like "!!!" or "*" flag your listing as spam and push it toward suppression.

Apply the Rule of Two for word repetition: never use the same word more than twice in a single title. Repeating keywords does not boost your ranking - it just wastes precious character space and makes the title harder to read.

• Primary keyword first, within the opening 10 words
• Brand, size, colour, and material in the next 40-50 characters
• No promotional phrases or excessive special characters
• No single word repeated more than twice

Following these four rules produces a title that displays cleanly on every device, satisfies the A9 algorithm, and keeps your listing well away from suppression.

Avoiding Prohibited Title Phrases

Amazon rejects roughly one in five new listings for policy violations, and a bad title is one of the fastest ways to get flagged. Knowing what words to avoid saves you from having your product hidden before a single customer sees it.

Promotional language is the biggest trap. Phrases like "100% quality guaranteed" or "Best Seller" are banned from titles - Amazon treats them as spam signals, not selling points.

Price information is also off-limits. Writing "Only $9.99!" or "Buy 2 Get 1 Free" in your title breaks Amazon's rules immediately, and the listing gets suppressed - meaning it disappears from search results entirely.

Suppressed listings are products Amazon hides from shoppers because the content breaks a policy. You can find them in Seller Central under "Manage Inventory" by clicking the "Suppressed" button, but it is far easier to write a clean title from the start.

All-caps words are another common mistake. Writing "WATERPROOF JACKET" instead of "Waterproof Jacket" triggers Amazon's filters because all-caps text reads as shouting - and Amazon's algorithm flags it the same way spam filters flag screaming subject lines in email.

Here are the four title elements Amazon explicitly bans:

• Satisfaction or quality claims - for example, "100% quality guaranteed"
• "Best Seller" or any similar sales-rank boast
• Price or promotional details - for example, "free shipping" or discount offers
• Words written entirely in capital letters

Avoiding these is simpler than it sounds. Describe what the product is and what it does - not how great it is or what it costs. "Stainless Steel Water Bottle 32oz Leak-Proof Lid" passes every check; "BEST Water Bottle - 100% Guaranteed, Only $15!" fails on three counts.

Building on the 80-character mobile limit covered in the previous section, a short, clean title naturally leaves no room for banned filler anyway. Every character you waste on "guaranteed" or "best" is a character stolen from a useful keyword.

Write your title, then read it back and ask one question: does this describe the product, or does it sell the product? Amazon's title field is for description only - the selling happens in your bullet points, which the next section covers in full.

Highlighting Benefits Before Technical Features

Specs alone do not sell products - feelings do. A shopper scanning Amazon does not stop to read a wall of numbers. They stop when something speaks directly to their problem.

Amazon gives you exactly five bullet points per listing, with up to 500 characters each. That is your entire window to convince a buyer before they scroll past. Most sellers waste it by leading with measurements and materials. Honestly, that is the single biggest mistake beginners make.

Benefit-first writing flips the order. Instead of starting with a spec, you start with the solution that spec provides. The spec follows as proof, not as the headline.

For example, do not open a bullet with "Made from 304 stainless steel." Open with "Keeps drinks cold for 24 hours" - then add "thanks to double-wall 304 stainless steel construction." The material becomes the reason, not the point.

Building five strong bullets follows a clear process. Each one targets a different buyer concern, weaves in a keyword naturally, and closes with a specific detail.

1. Start with a problem solved - Open every bullet by naming what the buyer gains or avoids. "No more tangled cables" beats "Includes cable management system."
2. Add the keyword naturally - Drop your search term into the sentence where it fits without forcing it. Stuffing keywords reads badly and shoppers notice.
3. Back it up with specifics - Include exact details: dimensions, materials, weight, or compatibility. "Fits bags up to 15 inches" is far stronger than "fits most bags."
4. Keep each bullet under 500 characters - Amazon cuts off anything beyond that limit. Short, punchy bullets also scan faster on mobile screens.
5. Cover a different benefit each time - Spread your five points across durability, ease of use, size, safety, and compatibility. Repeating the same angle wastes a slot.

Every bullet should answer one silent question the buyer is already asking: "Why does this matter to me?" Answer that first, then prove it with the technical detail.

Done right, your five bullets work as a fast checklist that confirms the product fits the buyer's life - which is exactly what moves them toward the "Add to Cart" button.

Formatting Bullets Without Forbidden Icons

Amazon bans emojis and special characters in bullet points. No stars, arrows, checkmarks, or decorative symbols - plain text only. This catches a lot of new sellers off guard.

Without icons, your bullets need structure to stand out. The standard method is a capitalized lead-in, where the first few words of each bullet are written in ALL CAPS before a dash or colon. For example: "WATERPROOF DESIGN - keeps your gear dry in heavy rain."

Capitalized lead-ins act as mini-headlines. Shoppers scanning fast can catch the main point without reading the full sentence. Honestly, this single formatting trick does more work than any emoji ever could.

Each bullet point allows up to 500 characters, but shorter is almost always better. Pack in the key benefit, one supporting detail, and stop. Padding a bullet to hit a character count helps nobody.

Bullet order matters more than most sellers realise. Put your strongest three points at the top, because many shoppers never scroll past them. Amazon gives you five bullet points total - treat the first three as prime real estate.

• Bullet 1 - lead with your biggest benefit or the problem your product solves
• Bullet 2 - highlight a key feature with a specific detail (material, size, or measurement)
• Bullet 3 - address a common concern or objection buyers have
• Bullet 4 - add a secondary feature or compatibility detail
• Bullet 5 - include warranty, guarantee, or brand reassurance

Line breaks provide the only real visual separation between bullets in plain text. Amazon's system handles this automatically, so you do not need to add manual spacing - just keep each bullet as its own clean block of text.

One mistake beginners repeat is starting every bullet with the word "Includes" or "Features." Benefit-first language converts better than feature-first language every time. Lead with what the buyer gains, then explain how the product delivers it.

Avoid HTML tags entirely inside bullet fields. Since July 2021, Amazon does not support them in standard listing fields, and using them triggers Error Code 90122, which can suppress your listing from search results.

Getting bullets right is really about discipline - clear language, a logical order, and no formatting shortcuts. That same discipline carries directly into the product description itself, where you have 2,000 characters to tell the full story of why someone should buy.

Writing For The 2,000-Character Limit

Amazon gives you exactly 2,000 characters to tell your product's story - that is roughly 300-350 words, about the length of a short newspaper article.

Wasting even 50 characters on vague filler like "great quality product" leaves real selling power on the table. Every word must earn its place.

Plan to spend 2-4 hours writing this section. That sounds long, but a tight character limit is harder to work with than an open one - cutting always takes more time than adding.

Build Your Description In Four Parts

Structuring your 2,000 characters into four clear parts stops you from rambling and keeps the reader moving toward a purchase.

1. Write a slogan - Open with one punchy line that captures what your product does and who it is for. Keep it under 100 characters so it hits hard and leaves room for everything else.
2. Describe the problem - Name the specific frustration your buyer feels before they find your product. Buyers connect with descriptions that show you understand their situation, not just your item.
3. List your unique selling points (USPs) - Unique selling points, or USPs, are the specific features that separate your product from every other option on the page. State them plainly: materials, size, how it works, what makes it last longer.
4. End with a call to action - A call to action is a direct instruction that tells the reader what to do next, such as "Add to cart today" or "Order now and use it this weekend." Short and direct wins here.

Following this four-part structure turns a block of plain text into a persuasive narrative - no complex formatting needed.

Since July 2021, Amazon banned HTML tags from standard product descriptions, so bold text and bullet lists are no longer available in this field. Line breaks are your only formatting tool, which means your word order and sentence rhythm do all the heavy lifting.

Keeping each part of your description tight also protects you from Error Code 90117 - Amazon's automatic rejection for descriptions that exceed the 2,000-character limit. Write in a plain text editor that counts characters as you type, and check your total before you submit.

Adapting To The No-HTML Environment

Amazon quietly changed the rules in July 2021, and thousands of sellers did not notice until their listings broke. Before that date, you could paste HTML tags like <b> or <i> directly into your product description to bold or italicise words. That option is gone.

Plain text is now the only format Amazon accepts in the standard product description field. Bold, italics, and underlining are all off the table. Any HTML tag left in your listing will trigger Error Code 90122 - Amazon's way of saying it found code where it expected plain words.

Getting that error is more than an annoyance. Amazon hides listings that fail its checks, which means buyers searching for your product simply will not find it. Remove every HTML tag from your description, title, and bullet points, then resubmit the listing to clear the error.

Without bold or italics, line breaks become your primary formatting tool. A line break creates a small gap between blocks of text, giving the reader's eye a place to rest. Use them between your opening hook, your product details, and your call to action to create a clean, readable structure.

White space works harder than most sellers expect. Short paragraphs separated by line breaks feel easier to read than a solid block of text, even when the word count is identical. Buyers scan before they read, so that visual breathing room keeps them on the page.

Emphasis now has to come from your word choices, not your formatting. Instead of bolding a benefit, lead the sentence with it. Write "Waterproof seams keep your gear dry on the trail" rather than burying "waterproof" mid-sentence. Strong verbs and specific details carry the weight that bold text used to handle.

Amazon's search algorithm also indexes your description as plain text, which is actually useful. Every word you write goes directly into the index with no HTML clutter in the way. Clear, specific language serves both the reader and the algorithm at the same time.

Qualifying For Amazon Brand Registry

Sellers who skip Brand Registry lock themselves out of A+ Content entirely - and that means staying stuck with plain text while competitors show off rich visuals. Before you can build those visual layouts, you need to meet three hard requirements Amazon won't bend on.

First, you need a Professional Selling Account. This is the paid seller tier on Amazon, which costs $39.99 per month. The free Individual account does not qualify, full stop.

Second, you need an active or pending registered trademark for your brand. A trademark is an official legal registration that proves you own your brand name or logo. Amazon accepts trademarks from most major countries, including the US, UK, EU, Canada, and Australia.

Third, your account must carry Brand Representative status inside Seller Central. This simply means Amazon recognises you as the official owner or authorised agent of that brand.

How To Enroll Step By Step

1. Go to brandregistry.amazon.com and sign in with your Seller Central account.
2. Enter your brand name exactly as it appears on your trademark registration.
3. Submit your trademark registration number and the country where it was issued.
4. List the product categories your brand sells in.
5. Verify ownership - Amazon sends a code to the trademark contact email on file with your country's trademark office.
6. Wait for Amazon's approval, which typically takes a few days to a couple of weeks.

Once approved, you gain access to Basic A+ Content, which lets you build up to five visual modules per product listing. Brands that qualify for Premium A+ Content get up to seven modules, plus larger images, videos, and Q&A sections.

One fact that surprises most beginners: A+ Content is not indexed by Amazon's search algorithm for SEO. Your standard text description still does the keyword heavy lifting. A+ Content wins customers visually after they land on your page - it does not help them find you in the first place.

Knowing that distinction changes how you plan your listing. Your text description carries the SEO load, and your visual modules handle conversion - which means the quality of those modules matters enormously, starting with the images inside each one.

Designing High-Resolution Product Modules

Upload a blurry product image to your A+ Content and shoppers will click away before reading a single word. Visual quality is the first signal buyers use to judge whether a brand is trustworthy, so getting your image specs right is non-negotiable.

Every image you upload should be at least 300 dpi - dpi stands for "dots per inch," which measures how sharp an image looks when displayed. Higher dpi means crisper, cleaner visuals, especially on high-resolution phone screens.

File size matters just as much as sharpness. Keep each image under 2MB so pages load fast - Amazon accepts JPEG and PNG formats, both of which compress well without destroying quality.

Your main product image needs a pure white background, and the product itself must fill at least 85% of the frame. Amazon also requires a minimum of 1,000 pixels on the longest side, so never upload a small photo and try to stretch it larger.

Beyond the main product shot, A+ Content lets you build several types of visual modules. Each serves a different purpose and together they tell a complete story about your product.

• Lifestyle photos - show the product being used by a real person in a real setting
• Comparison charts - compare your own product variants side by side (Amazon only allows comparisons within the same brand)
• Technical spec modules - display dimensions, materials, and performance data clearly
• Infographics - use simple icons and short labels to highlight key features visually

Honestly, most beginners skip comparison charts entirely - which is a mistake. Shoppers who are deciding between two of your own products will convert faster when they can see the differences at a glance.

Use a tool like Adobe Photoshop, Canva Pro, or even free software like GIMP to build these assets. If you are working with a designer, share the specs in the table below so nothing gets submitted at the wrong size.

Module Type	Minimum Resolution	Ideal DPI	Max File Size	Accepted Formats
Main product image	1,000px longest side	300 dpi	Under 2MB	JPEG, PNG
Lifestyle photo	1,000px longest side	300 dpi	Under 2MB	JPEG, PNG
Infographic	1,000px longest side	300 dpi	Under 2MB	JPEG, PNG
Comparison chart	1,000px longest side	300 dpi	Under 2MB	JPEG, PNG

Submitting images that fall outside these specs is one of the fastest ways to get a listing suppressed - and fixing suppressed listings is a frustrating process that can cost you days of visibility.

Fixing Error Codes 90122 And 90117

Most upload failures feel mysterious until you know exactly what Amazon is complaining about - and these two errors are the most common ones sellers hit when submitting a product description.

Error 90122 means Amazon found prohibited HTML in your listing. Since July 2021, Amazon stopped supporting HTML tags in standard product descriptions. If your text contains anything like <b>, <br>, or <p> tags, Amazon rejects the whole submission.

Fixing 90122 is straightforward. Open every field in your listing - title, bullet points, and description - and delete any tag that looks like code inside angle brackets. Plain text only.

Error 90117 is a character count problem. Your product description has gone over Amazon's 2,000-character limit. Every letter, space, and punctuation mark counts toward that number.

Cutting your description down feels painful, but it forces tighter writing. Paste your text into a free character counter tool, then trim until you land below 2,000 characters. If you are unsure of the exact limit for your category, download the inventory file template for that category directly from Seller Central - it lists the precise limits.

Here is how to locate and fix both errors inside Seller Central:

1. Go to Manage Inventory - Click the "Suppressed" button if it appears. This filters your listings to show only the ones Amazon has hidden from search results.
2. Open the "Fix Your Products" tab - Amazon lists every flagged error here with the specific error code attached, so you know exactly which field caused the problem.
3. Edit and remove the flagged content - Strip out HTML for 90122, or shorten your text for 90117. Save your changes and resubmit.
4. Delete and relist via SKU if the error persists - Sometimes an attribute gets locked on the backend. Back up all your listing content first, delete the SKU, wait 24 hours for Amazon's system to clear it, then relist using an Inventory Flat File upload.

That 24-hour wait after deleting a SKU is genuinely non-negotiable - relisting too early just recreates the same locked error. Honestly, skipping the backup step before deletion is the single biggest mistake beginners make here, and it means rebuilding your listing from scratch.

Both errors are fully fixable without contacting Seller Support, which saves days of waiting for a response that often just tells you to do exactly this.

Recovering A Suppressed Product Listing

Your product was live yesterday, and today it has vanished from Amazon search results entirely. That disappearance has a name: a listing suppression, which means Amazon has hidden your product because something in your listing breaks its rules.

Finding a suppressed listing is straightforward. Go to Seller Central, open "Manage Inventory," and look for a red "Suppressed" button near the top of the page. Clicking it filters your inventory to show only the affected products.

Once inside, head to the "Fix Your Products" tab. This tab lists every specific problem Amazon found - missing information, bad images, policy violations, or wrong category placement. Each issue gets its own flag, so you know exactly what to fix.

Image problems are one of the most common causes of suppression. Amazon requires your product to fill at least 85% of the image frame. A tiny product floating in a sea of white background will trigger a suppression just as fast as a blurry photo will.

Policy violations are another frequent trigger. Phrases like "best-selling" or "100% satisfaction guaranteed" in your title or description break Amazon's rules around promotional content. Remove them, and resubmit the listing.

Wrong category placement also hides listings. This is called an incorrect Browse Node - Browse Nodes are Amazon's internal category codes that tell the system where your product belongs. If your kitchen gadget lands in the automotive section, shoppers searching the right category will never find it. Download the latest category template from Seller Central and reselect the correct node.

1. Open "Manage Inventory" and click the "Suppressed" button.
2. Review every flagged error under the "Fix Your Products" tab.
3. Fix image issues - ensure your product fills 85% of the frame.
4. Remove any promotional language from titles, bullet points, or descriptions.
5. Correct your Browse Node using the latest Seller Central category template.
6. Resubmit the listing and allow up to 24 hours for changes to go live.

After resubmitting, changes can take up to 24 hours to show across Amazon's search results. Monitoring your "Manage Inventory" page daily keeps suppression from quietly costing you sales for days at a time.

Conclusion

Amazon rewards listings that are built correctly from the start. Every section - title, bullet points, description - works as a single system, and a weak link in any one part costs you visibility and sales.

• Keep your title at 80 characters or fewer. That is the exact point where mobile screens cut off your text, and most Amazon shoppers browse on a phone.
• Your five bullet points have a 500-character limit each. Use that space to lead with a benefit, not a feature - what the product does for the buyer, not just what it is.
• The standard description field caps at 2,000 characters and has banned HTML since July 2021. Plain text and line breaks are your only formatting tools now.
• A complete listing - from keyword research through final review - takes roughly one to two days for a single product. Budget that time before your launch date.
• After you publish, expect a 24-hour propagation delay before your changes appear in search results. That is normal. It is not a sign something went wrong.

Today, open Amazon's search bar and type your main product category. Write down every auto-complete suggestion that appears. That free data is your first keyword list, and it costs nothing.

Then paste your draft title into a character counter - there are free ones online - and confirm it hits 80 characters or fewer before you submit anything.

A listing you never test is a listing you never improve.
