Amazon Product Description HTML Formatting 2026: Which Tags Still Work
Amazon still supports a limited set of HTML tags in product descriptions for non-brand-registered sellers in 2026. Here is what works, what is ignored, and what breaks your listing.
HTML in Amazon Product Descriptions
Brand-registered sellers use A+ Content instead of the product description field, which renders as rich images and formatted text. For sellers without Brand Registry, the product description field still supports a limited set of basic HTML tags. Knowing which tags work and which are stripped or broken saves time and avoids formatting errors that hurt your listing presentation.
Tags That Work in Product Descriptions
These tags are supported and render as expected on most Amazon marketplaces: `<b>` (bold text), `<i>` (italic text), `<br>` (line break), `<ul>` and `<li>` (unordered list, which creates bullet points), and `<p>` (paragraph break with extra whitespace). Use `<br>` for simple line breaks and `<ul>/<li>` for bulleted lists within the description body.
Tags That Are Stripped
Amazon strips and ignores: `<h1>` through `<h6>` (heading tags), `<div>`, `<span>`, `<table>`, `<a>` (links), CSS inline styles, and JavaScript. If you include these, the tag is simply removed and the text content remains, often creating run-on sentences without the expected spacing.
What Breaks the Listing
Unclosed tags (`<b>` without `</b>`) can cause the bold formatting to extend through the rest of the description. HTML entities like `&`, ` ` are sometimes rendered correctly and sometimes shown literally, so test on your listing. Using `<br>` excessively to push competitors' sections off-screen is against Amazon policy and can trigger a listing suppression for "formatting manipulation".
Best Practice for Non-Brand Listings
Lead with your most important benefit in the first sentence. That is the part visible without expansion. Use `<ul>/<li>` to create a short bulleted feature list (3-5 bullets maximum in the description, since bullet_point fields handle your main bullets). Use `<b>` sparingly for key terms. Keep total character count under 2,000 characters (Amazon's recommended maximum for the description field). ## Where the Description Field Still Shows Up
Before spending time on formatting, know when the field is even rendered. If the ASIN has approved A+ Content, Amazon replaces the product description block with the A+ modules on the desktop detail page, and your HTML is not displayed at all. Without A+ Content, the description renders under a "Product Description" heading below the bullets.
The field is still worth filling in either case. Amazon indexes the description text for organic search whether or not it is displayed, it is what shows if your A+ Content is ever removed or rejected, and some placements and marketplaces fall back to it.
Byte Limits, Not Character Limits
The description field accepts up to 2,000 characters in most categories, and Amazon's own guidance recommends staying well under that. As with the backend search terms field, the underlying limit counts bytes, so accented characters on European marketplaces consume more than one each. HTML tags count toward the limit too, which is a real cost when a list of eight items carries sixteen tags.
A Structure That Survives the Filter
This uses only tags that live through Amazon's sanitiser, and it renders consistently on desktop and in the mobile app. Build the field in this order:
- `<b>What it is</b>` then `<br>` then one sentence naming the product and the buyer it is for
- `<br><br>` to open a gap, then `<b>Why it is built this way</b>` and two or three sentences on the material, the mechanism or the process, with a number in them
- `<br><br>` then `<b>What you get</b>` followed by a `<ul>` of three or four `<li>` items, each carrying a quantity, a dimension or a compatibility note
- `<b>Good to know</b>` then `<br>` and the limitation you would rather not mention. Stating it costs you a few sales and saves you more returns
Note the doubled `<br><br>` between blocks. A single `<br>` gives a line break with no gap, and `<p>` behaves inconsistently across marketplaces, so two breaks is the dependable way to get visible space between sections.
Test Before You Trust It
Formatting that looks right in the Seller Central preview is not proof. Submit, wait for the change to propagate, which usually takes fifteen minutes to a few hours, then check the live page in three places: desktop web, mobile web, and the Amazon mobile app. The app is the one that most often ignores spacing that the desktop page renders.
If your text arrives as one unbroken block, the usual cause is that you pasted from a word processor. Curly quotes, non-breaking spaces and hidden formatting characters come across with the text and Amazon strips or mangles them. Paste through a plain text editor first.
Flat File Versus the Seller Central Editor
Uploading the description through a flat file behaves differently from typing it into the editor. In a spreadsheet, the HTML has to sit in a single cell, and Excel will happily break it across lines if the cell contains a newline. Write the HTML as one continuous line with no carriage returns, and check the cell is formatted as text rather than general, otherwise leading characters get eaten.
Flat file uploads also overwrite silently. If the description column is blank in your upload template, some category templates clear the existing description rather than leaving it alone. Populate the column or remove it from the file.
Frequently Asked Questions
What HTML tags work in an Amazon product description?
Basic formatting tags survive: bold, italic, line break, paragraph, and unordered lists with list items. Amazon strips headings, divs, spans, tables, links, inline CSS and any script. The stripped tag disappears but its text content remains, which is why a stripped heading usually joins onto the sentence after it.
Can I put a link in my Amazon product description?
No. Amazon removes anchor tags and prohibits external URLs, email addresses and phone numbers anywhere in listing copy. Including them risks the listing being suppressed rather than simply reformatted.
How long should an Amazon product description be?
The field accepts up to 2,000 characters in most categories. Aim for 800 to 1,200 characters of real content. The first sentence is the one most buyers read before deciding whether to expand, so the strongest benefit belongs there rather than in a general introduction.
Why is my Amazon description showing as one block of text?
Either your line break tags were stripped, or the text was pasted from a word processor and carried hidden characters. Rewrite it in a plain text editor using doubled line break tags between sections, resubmit, and check the live page rather than the editor preview.
Does A+ Content replace the product description?
On the desktop detail page, yes. When approved A+ Content exists for an ASIN, Amazon shows the A+ modules in place of the plain description. Keep the description field populated anyway, because it stays indexed for search and it is what appears if the A+ Content is ever removed.
