About Sydon Sonar
Sydon Sonar puts research on the Amazon pages you are already looking at.
No separate dashboard, no copying ASINs into another tool.
ON A SEARCH RESULTS PAGE
A panel appears above the listings with a sortable, filterable table: estimated
monthly sales and revenue per listing, price, sales rank, review count, rating,
seller count and fulfillment. Choose which columns you want and the export
follows your choice. Underneath, a revenue breakdown by brand, fulfillment method
and size tier shows who actually owns the niche.
ON A PRODUCT PAGE
A summary strip above the listing, and a detail panel below it:
- Units and revenue for the variation you are viewing, and for the whole family
- 90-day price and sales-rank history
- FBA fee breakdown: referral and fulfillment, with the total
- Sellers on the listing and Buy Box ownership
- A content audit: images in the carousel, A+ content
- Package specs, size tier and dimensional weight
- A variation matrix: every child ASIN with its own price, rank and share
- A profit calculator that takes your own costs and returns net, margin and ROI
WHAT THE NUMBERS ARE
Sales and revenue are Sydon 30-day estimates, labeled as such
wherever they appear. Where a figure has not been published, Sonar shows a dash
rather than a zero: a blank and a real zero are different things, and treating
them as the same is how a seller comes to believe something false about a
listing. Nothing is invented to fill a gap, and no cost of goods is ever guessed
on your behalf.
IT DOES NOT SPEND YOUR ALLOWANCE WITHOUT ASKING
Opening a search or product page costs nothing. Sonar shows what is
already on screen and offers a scan with the cost written on the button, so a
lookup is only ever spent because you chose to spend it. What you have left is on
the button itself, and under "Today's usage" in the toolbar popup.
EXPORTS
Export the table as CSV, or a formatted report with charts that you can print to
PDF. Set your own company name, logo and accent color once, and reports go out
under your brand, which is useful if you do product research for clients.
YOUR DATA
To fill the panel, the extension sends the ASINs of the listings you scan, and a
session token that identifies you, to our servers, which pass the ASINs to the
data providers that return the figures shown. If you use Top Keywords, the
search term you typed is sent too. If you use Analysis, the search term and a
summary of the results go to a language-model service. Your email address is used
to sign you in and for nothing else. Your cost inputs stay in your browser and sync
across your own devices through your browser's sync. We do not sell this data,
use it for advertising, or let anyone read it except with your consent or as
the law requires.
GETTING STARTED
Sign in with your email. A confirmation link, no password, no account to create.
Signing in unlocks the provider data and a daily allowance of lookups.
Without an account the extension still runs, showing only what can be read from
the page itself.
Works on the US marketplace only.
