AI search optimisation
Built for How Amazon Search Actually Works in 2026
Amazon doesn't rank on keywords alone any more. Three systems now decide which listings win — and most listing tools are still writing for the old one. Ecom Wizard writes every listing for all three, so yours stay visible as Amazon's search gets smarter.
“A game-changer for our company. We have over 100,000 parts in our catalogue and Ecom Wizard optimises all of them. The sales dashboard and SKU-level deep-dive are now a daily must-have for our business.”
What it does
- • Writes for the classic ranking engine — the signals that have always mattered: conversion rate, click-through and sales velocity.
- • Writes for COSMO, Amazon’s semantic layer — so your listing is understood by who it’s for, what problem it solves and where it fits, not just the words in it.
- • Writes for Rufus & Alexa — the AI shopping assistants that read your listing to answer buyers’ questions, so your copy gives the right answers.
- • Keeps every listing coherent and natural — because Amazon now penalises keyword-stuffed copy instead of rewarding it.
- • Stays current with Amazon’s 2026 rules — the 75-character title limit and the new searchable Item Highlight field, built in automatically.
- • Applies the same standard across Amazon UK, Europe, and every other channel you sell on.
The three systems that now rank your listing
For years, one engine decided Amazon rankings — largely conversion rate, click-through and sales velocity, driven by keyword matching. That engine still matters. But two AI layers now sit on top of it. COSMO is Amazon’s semantic relevance model: it reads meaning and context — who a product is for, what problem it solves, the situations it’s used in — not just literal keywords. And Rufus (with Alexa) is Amazon’s AI shopping assistant, which reads your listing to answer shoppers’ questions directly. A listing has to satisfy all three at once.
Why keyword-stuffing now backfires
The old playbook was to cram every keyword into the title and bullets. Under the AI layers, incoherent keyword-stuffed copy is penalised, not rewarded — it gives the semantic model nothing meaningful to understand and reads badly to shoppers, hurting the conversion rate that still drives ranking. Winning listings read as natural, situational language. That’s a genuine shift, and it’s where a lot of listings — and a lot of listing tools — are now getting left behind.
Ahead of the 2026 changes
From 27 July 2026 Amazon caps most titles at 75 characters and adds a new, searchable 125-character Item Highlight field. Ecom Wizard already writes to those rules, and uses each field for what it’s now best at — so your listings are built correctly from the start, not retrofitted after Amazon rewrites them for you.
Built in, on every listing
This isn’t a setting you turn on or a report you read — it’s how Ecom Wizard writes, every time. You generate a listing as normal; the engine handles the rest, so your whole catalogue is written for how Amazon search works today, whether that’s one product or a hundred thousand.

What is Amazon COSMO?+
COSMO is Amazon’s AI semantic-relevance layer. Instead of matching keywords literally, it reads meaning and context — who a product is for, what problem it solves and the situations it’s used in — to match listings to what shoppers actually mean.
What is Amazon Rufus?+
Rufus (alongside Alexa) is Amazon’s AI shopping assistant. It reads product listings to answer shoppers’ questions in natural language, so a clear, well-written listing gives buyers the right answers and is more likely to convert.
Does keyword-stuffing still work on Amazon?+
No — it now works against you. Amazon’s AI layers penalise incoherent, keyword-stuffed copy, and it reads badly to shoppers, hurting conversion rate. Natural, situational language is what ranks now.
Is Ecom Wizard up to date with Amazon’s 2026 changes?+
Yes. It writes to the 75-character title limit and the new 125-character Item Highlight field that took effect on 27 July 2026, and it writes for the AI search layers (COSMO and Rufus) as well as the classic ranking engine.
Do I need to do anything to get this?+
No. It’s how Ecom Wizard writes every listing — there’s nothing to configure. Generate a listing as normal and it’s built for how Amazon search works today.
