A four-step playbook diagram for removing an Amazon listing hijacker: detect, document, remove, prevent

Amazon Listing Hijacker Removal: A 4-Step Detect, Document & Takedown Playbook (2026)

Disclosure: This article contains affiliate links — we may earn a commission at no extra cost to you. This does not affect our rankings or conclusions. An Amazon listing hijacker is a third-party seller who attaches an offer to your ASIN and starts winning the Buy Box — often with counterfeit, used, or materially different units sold under your brand name. If it is happening right now, do these four things in order: confirm it is actually a violation, buy a unit as evidence, file the right takedown report, then close the door so it cannot happen again. This guide is the neutral, do-it-yourself version of that process — no agency retainer required — with the official Amazon tools verified against Amazon’s own pages (checked 2026-07-22). ...

Title card for an Amazon referral fees guide covering category rates and calculation

Amazon Referral Fees Explained: Rates by Category and How to Calculate Them (2026)

Amazon Referral Fees Explained: Rates by Category and How to Calculate Them (2026) An Amazon referral fee is the commission Amazon charges on every item you sell—a percentage of the total sale price, deducted automatically whether you use FBA or fulfill orders yourself. For most categories the rate is 8% to 17%, with 15% being the single most common figure, and Amazon takes a minimum of $0.30 per item even when the percentage works out to less. It is a separate charge from FBA fulfillment fees, and it is the one fee that applies to every seller on the marketplace. ...

Title card for an Amazon suspension appeal guide listing the three Plan of Action parts: root cause, corrective, preventive

Amazon Suspension Appeal: A Reusable Plan of Action Template (2026)

If your Amazon seller account was deactivated, the appeal that gets it back is almost always a Plan of Action (POA) — a document with three parts: the root cause of the problem, the corrective actions you have already taken, and the preventive measures now in place. Amazon reviewers read for those three things specifically, in that order. This guide gives you a neutral, self-serviceable template for writing one, plus the evidence each suspension type actually needs. ...

Amazon product title being trimmed to a 75-character limit

Amazon's 75-Character Title Limit: What Changes July 27 (and How to Prepare)

Starting July 27, 2026, Amazon product titles in every category except media must fit inside 75 characters, spaces included. Media — books, music, and video — is the one carve-out. Anything still over the line after that date gets rewritten automatically by Amazon’s AI, and only brand-registered sellers get a window to review the change first. This is a hard formatting rule, not a suggestion, so the practical question for most sellers is which keywords to keep and which to move somewhere else. ...

Comparison of the best Amazon profit analytics tools for 2026

Best Amazon Profit Analytics Tools (2026): Accuracy and Billing Compared

Disclosure: This article contains affiliate links — we may earn a commission at no extra cost to you. This does not affect our rankings or conclusions. The best Amazon profit analytics tools in 2026 are Sellerboard for budget accuracy, SellerLegend for high order volumes, and Helium 10 Profits if you already run its research suite — but the feature list is not what separates them. Every one of these tools promises “accurate” profit; what actually differs is whether their number reconciles to your Seller Central payouts, and whether you can cancel without a fight. This roundup ranks the field on those two axes, not on marketing checklists. ...

Best Amazon review request software compared: FeedbackWhiz, FeedbackFive, SageMailer, Feedback Genius

Best Amazon Review Request Software 2026: Compliant Feedback Tools Compared

Disclosure: This article contains affiliate links — we may earn a commission at no extra cost to you. This does not affect our rankings or conclusions. Best Amazon Review Request Software 2026: Compliant Feedback Tools Compared The best Amazon review request software automates Amazon’s own “Request a Review” message on autopilot and monitors new reviews, without ever asking buyers for a positive review. For most sellers FeedbackWhiz (from $20/mo) and FeedbackFive (from $34/mo) are the category defaults; SageMailer is the budget pick with a genuine free plan; and Seller Labs’ Feedback Genius is the longest-running option. But every paid tool now triggers the exact same Amazon message the free button sends, so what you’re really buying is scheduling, review monitoring, and analytics — not a higher review rate. There is no single best pick: match the tool to your order volume, how much monitoring you need, and how carefully you read the billing terms. ...

Retail vs online arbitrage sourcing flow into an Amazon listing

Amazon Arbitrage Explained: Retail vs Online Arbitrage, Compliance Red Lines & Tools (2026)

Disclosure: This article contains affiliate links — we may earn a commission at no extra cost to you. This does not affect our rankings or conclusions. Amazon Arbitrage Explained: Retail vs Online Arbitrage, Compliance Red Lines & Tools Amazon arbitrage is the practice of buying products at a discount from a retailer — in a physical store (retail arbitrage) or from an online store (online arbitrage) — and reselling them on Amazon for a higher price. It is a legitimate, low-capital way to start selling, and Amazon does not ban it. What gets sellers into trouble is not the model itself but how they source, list, and ship. ...

Amazon COSMO intent-based search: matching products to shopper needs, not just keywords

Amazon COSMO Explained: How Amazon's AI Intent Search Changes Ranking

Disclosure: This article contains affiliate links — we may earn a commission at no extra cost to you. This does not affect our rankings or conclusions. Amazon COSMO is a machine-learning system Amazon built to mine “common sense” knowledge about shoppers from their behavior, so search can infer the intent behind a query instead of matching keywords alone. It was published by Amazon’s own researchers at the ACM SIGMOD 2024 conference. For sellers, COSMO matters because it pushes ranking further toward “does this product solve the shopper’s underlying need?” — but a lot of what circulates online about it is interpretation, not confirmed fact, so this guide separates the two carefully. ...

Amazon FBA reimbursement services compared by commission rate: GETIDA, Refully, Eva, Refunzo

Best Amazon FBA Reimbursement Services 2026: Commission Rates Compared

Disclosure: This article contains affiliate links — we may earn a commission at no extra cost to you. This does not affect our rankings or conclusions. Best Amazon FBA Reimbursement Services 2026: Commission Rates Compared The best Amazon FBA reimbursement service depends on whether you want a done-for-you audit or you’re willing to file claims yourself. For a hands-off service, GETIDA is the market default at a 25% commission with your first $400 recovered free; Eva undercuts the field at a flat 10%; and Refully sits in the middle at 18%. If you’d rather keep 100% of every recovery, a self-service finder like Helium 10’s Refund Genie (free inside its Diamond plan) or a flat-fee audit tool like ReimburseOps ($19/mo) flags the discrepancies and you submit the cases. There is no single best pick—the right one depends on your recovery volume, how much documentation work you’ll do, and your tolerance for commission on money Amazon might have paid you anyway. ...

Best Amazon Seller Chrome Extensions (2026): A Job-by-Job Comparison There is no single best Amazon seller Chrome extension — the right one depends on the job. For price and demand history, install Keepa; it is free forever and the most-installed of the group. For an all-in-one research overlay on the product page, Helium 10 (Xray) and Jungle Scout lead. For retail and online arbitrage sourcing, SellerAmp SAS is the specialist. And for capturing a listing’s images and video, an asset-downloader like ASINCrate does the one thing the research tools do not. ...

Online arbitrage sourcing tools compared: Tactical Arbitrage, SellerAmp, BuyBotPro, Scan Unlimited

Best Online Arbitrage Sourcing Tools 2026: Tactical Arbitrage, SellerAmp, BuyBotPro & Scan Unlimited Compared

Disclosure: This article contains affiliate links — we may earn a commission at no extra cost to you. This does not affect our rankings or conclusions. Best Online Arbitrage Sourcing Tools 2026 No single tool does online arbitrage sourcing end to end — the working setup is a bulk scanner to find deals, an on-page analyzer to check each one, and Keepa underneath both for price history. For most sellers in 2026 that means SellerAmp SAS (from $19.95/mo) as the everyday deal analyzer, Tactical Arbitrage (now only inside Three Colts’ Seller 365 bundle at $69/mo) or Scan Unlimited (free tier, then $720/yr) for bulk list scanning, and a free Keepa account as the data backbone. This guide compares the main online arbitrage software on 2026 pricing, real seller complaints, and where each one fits the sourcing workflow. All prices were checked on 2026-07-21. ...

Amazon Best Sellers Rank badge and sales rank on a product detail page

Amazon BSR Explained: How Best Sellers Rank Is Calculated (2026)

BSR (Best Sellers Rank) is Amazon’s relative popularity number that shows how a product sells compared to others in the same category — lower is better, #1 is the top seller. It is driven almost entirely by sales volume, weighted toward recent sales, and it updates frequently throughout the day. It is not a quality score, and it cannot be edited directly. This guide explains what BSR is, how Amazon says it is calculated, why the number behaves the way it does, and the honest answer to the question every seller eventually asks: can you actually “optimize” your BSR? ...
