Shelfverdict: Product Research Niche Checker

Is this Amazon niche worth it? A go or no-go verdict from the search page you are on, with the reasons shown.

You found a product idea on Amazon and have not spent anything yet. Shelfverdict reads the search page you already have open and gives that niche a go, a maybe or a no-go. The five checks behind the verdict sit beside it, each with its value and its limit, so you can disagree with it. HOW IT WORKS 1. Search Amazon for the product you are thinking of selling. 2. A verdict card appears above the results, and every result gets a small tag: organic or sponsored, with its review count as a bar. 3. Open a product to see its rank, price, reviews, who ships it and how many offers it has. 4. Open the Shelfverdict popup for the fee and margin calculator. THE FIVE CHECKS • Review barrier: the median review count of the top 10 organic results, at most 500 • Young listings: at least 3 of those 10 under 100 reviews, which shows a new listing can rank • Ad share: sponsored cards at most 30% of the cards on the page • Brand hold: no brand holding more than 3 of the top 10. Brands are guessed from the first word of each title and marked est. • Price band: median price of the top 10 between 15 and 50 in dollars or euros, 12 and 40 in pounds. Currencies are never converted No fails is a go, one fail a maybe, two or more a no-go. With fewer than 5 organic results there is no verdict. The review and price limits follow beginner rules of thumb; the ad and brand limits are our own. The card says its limits are rules of thumb, and estimates are marked est. FEES AND MARGIN The calculator takes your selling price, fulfilment fee, unit cost and other costs, and shows the referral fee, profit per unit, margin and return on cost. The referral rate comes from a table that lists the day each row was read. It holds Home & Kitchen, Sports & Outdoors and Pet Supplies on amazon.com and Cucina on amazon.it. Other categories and the fulfilment fee table are not included, because they depend on size and weight and could not be confirmed. You type that fee, with a link to Amazon's own calculator. WHAT IT DOES NOT DO • It reads only the page you have open. It never fetches an Amazon page on its own, so nothing runs in the background • No revenue figures and no search volumes. The monthly sales shown are Amazon's own "bought in past month" floors, or, in Pro, local estimates marked est. • It has been checked against saved amazon.com and amazon.it pages. The amazon.co.uk, amazon.de, amazon.fr and amazon.es pages are permitted, and the card says when a storefront has not been checked yet, because a missing figure may then be a layout change FREE AND PRO Free, with no cap: the verdict, the review barrier, the sponsored share, the brands, the product readout, Amazon's own "bought in past month" figure on each result with the floors of the top 10 added up, and the fee calculator. Pro: the rank, price and review count of each product you open, kept on your computer with the review growth between looks; monthly sales estimates marked est. for products where Amazon prints no figure, worked out on your computer from the rank and sales pairs you have collected and given only inside the rank range you have collected; saved niches with the products you picked; a CSV of the competitor table of the search you are on. Pro is a one-time payment with no subscription, either a lifetime pass or a one-year pass. The current prices are in the popup under Upgrade. New installs include Pro for 7 days, no card. When it ends, the Pro features switch off. The licence key comes with the Payhip receipt; paste it in the popup under Upgrade. PRIVACY Nothing from the pages you read leaves your computer: not the searches, the products, the prices or the reviews. The extension sends something only when you act. Activating or re-checking a Pro key sends the key. Pressing Send on the feedback form sends the text you typed, your email only if you entered one, and the version number. No account, no analytics. PERMISSIONS, AND WHY • storage: the last search, your saved niches and history, the licence key and the trial dates • Access to amazon.com, amazon.co.uk, amazon.de, amazon.it, amazon.fr and amazon.es: to read the search and product pages you open there, and nothing else Not affiliated with Amazon.
