Here’s a leak we find on the majority of Brand Registry catalogs we audit, and almost nobody knows it’s there: the moment you publish A+ Content, Amazon hides your plain-text product description on the detail page — so brands stop writing one. They leave the field blank, or paste in a single keyword-stuffed sentence from three years ago, and move on. It feels harmless. The page looks better without it.
It’s not harmless. You didn’t just hide a block of text. You deleted an indexed search surface and a Rufus data source at the same time, and you got a prettier page in exchange for real ranking and retrieval. This is one of the cheapest fixes on Amazon in 2026, and one of the least-done.
What actually happens when you turn on A+ Content
When A+ Content goes live, it renders in the “From the brand” / product description area of the page. The plain-text product description field — the 2,000-character block you filled out when you first created the listing — gets visually replaced. Shoppers see your beautiful modules instead of a wall of text. Good for them.
The trap is what happens behind the scenes. The description field is still part of your listing. It’s still submitted. It’s still stored. But because it no longer shows up on the page, brands treat it as dead and stop maintaining it. We open listing after listing where the A+ is gorgeous and the description field is either empty or holds one stale sentence written before the brand ever thought about search.
That’s the whole leak: A+ made the field invisible to you, so you stopped feeding two systems that still read it.
The two readers who still see your description
The plain description isn’t rendered on-page anymore, but two of the most important “readers” of your listing never stopped consuming it.
1. Amazon’s A9 search algorithm still indexes it. This is the part that surprises even experienced sellers. A+ Content is not indexed for search. Those keyword-rich module captions you’re proud of contribute nothing to organic discoverability. The plain-text description field, on the other hand, is indexed and does contribute to search visibility. Titles carry the most weight, backend terms and bullets matter, but the description is a genuine indexed surface — and when you blank it out, you’ve thrown away your only long-form indexed copy and replaced it with A+ that A9 can’t read at all. You made your page prettier and your search footprint smaller in the same move.
2. Rufus reads it. Amazon’s AI shopping assistant is trained on the product catalog, and when it decides whether your product is the right answer to a shopper’s natural-language question, it reads the whole listing — title, bullets, product description, A+ Content, reviews, and Q&A. The description is part of the data set the model draws from. An empty description field is 2,000 characters of context you declined to give the system that increasingly decides whether you make the consideration set. In a world where Rufus filters candidates on how completely and clearly you’ve described your product, a blank field is a self-inflicted handicap.
So the description field serves both the old world (A9 keyword ranking) and the new one (Rufus/COSMO semantic retrieval). It is one of the few surfaces that pays off on both sides of Amazon’s algorithm split — and it’s the one brands most reliably leave empty.
Why this is a real revenue leak, not a technicality
Do the math on what you gave up. You have exactly a handful of copy surfaces Amazon indexes: title (~200 characters), bullets, backend search terms, and the description (2,000 characters). When you turn on A+ and abandon the description, you’ve eliminated the single largest indexed free-text field you own — roughly ten times the character budget of your title — and put nothing indexable in its place, because A+ isn’t indexed.
Stack that on top of the completeness problem we see everywhere. Independent audits keep finding brand catalogs sitting at 30-40% structured-attribute completion in 2026, and empty description fields travel with thin attributes almost every time. It’s the same root cause: the invisible plumbing gets ignored because nobody sees it on the page. The brands losing organic ground to the Listing Quality signal are, disproportionately, the same brands with blank description fields. These aren’t two problems. They’re one habit — treating “not visible to me” as “not worth doing.”
We’re not going to pretend a description rewrite is a hero-image-sized CVR event. It isn’t. What it is: a free, un-glamorous, catalog-wide recovery of an indexed search surface and a Rufus input, at effectively zero cost and zero risk. On a $100K+/month catalog, “free and catalog-wide” is not a rounding error. It’s the kind of margin you leave on the table precisely because it isn’t exciting.
What to actually write in the description (it is not your bullets)
The most common wrong fix is copy-pasting your five bullets into the description field. Don’t. That wastes the one thing this field is good for.
Your bullets are scannable, benefit-first, and truncated hard on mobile — they’re built for the skimmer. The description is different real estate with a different job. Use the full 2,000 characters for contextual, natural-language prose that doesn’t appear in your title or bullets. That’s exactly what both A9 and Rufus reward and exactly what a keyword list can’t provide.
Concretely, the description should answer the questions your bullets don’t have room for:
- Use-case and fit context — who it’s for, when to reach for it, the specific situations it’s built for. This is prime Rufus retrieval fuel because shoppers ask Rufus in situational, natural language (“will this work for a small apartment kitchen,” “is this good for daily commuting”).
- Compatibility and edge cases — what it works with, and honestly, what it’s not for. The “not for” is where returns come from and where Rufus needs a clear answer.
- Materials, construction, and the story behind the spec — the sentence-level context a bullet compresses into two words.
- Secondary keywords in real sentences — the natural-language variants and long-tail phrasing that don’t fit the title, written as prose a human would actually read, not a comma-salad.
Write it for a person and the machine gets what it needs as a byproduct. Write it as a keyword dump and you’ll trip the exact quality signals you’re trying to feed.

FAQ
Does A+ Content replace my product description?
Visually, yes — A+ renders where the plain description used to show, so shoppers see your modules instead. But the description field still exists on the listing, is still submitted, and is still used by Amazon’s systems. It’s hidden, not deleted — unless you delete it by leaving it blank.
Is my product description still indexed if I have A+ Content?
Yes. The plain-text description field remains indexed by A9 whether or not A+ is present. A+ Content itself is not indexed for search. That’s exactly why abandoning the description in favor of A+ hurts your organic footprint.
Does Rufus actually read the product description?
Yes. Rufus is trained on the product catalog and reads the full listing — title, bullets, description, A+, reviews, and Q&A — to decide whether your product answers a shopper’s question. The description is part of that data set.
How long should the description be?
Use as much of the 2,000-character limit as you can fill with genuinely useful, non-repetitive context. This isn’t about padding — it’s about giving both A9 and Rufus real information that isn’t already in your title and bullets.
Should I just copy my bullets into the description?
No. That duplicates content the systems already have and wastes the field’s real advantage: room for natural-language, situational, compatibility, and use-case detail that bullets can’t hold. Write something new.
