Amazon Product Sourcer for
Real-Time ASIN Analysis

The price history chart is one of the most powerful features for making informed sourcing decisions. It displays the historical price trajectory of a product over weeks, months, or even years, giving you visibility into pricing trends that a single snapshot never could.

For example, if you see that a product's price has been steadily declining over the past six months, that's a red flag: it could indicate increasing competition, falling demand, or a race-to-the-bottom pricing dynamic. On the other hand, stable or gradually rising prices suggest a healthy market with consistent demand and disciplined competitors.

The chart also reveals seasonal patterns. Many Amazon products experience predictable price spikes during Q4 (Black Friday, Christmas), Prime Day, or back-to-school seasons. By studying these patterns, you can time your inventory purchases to buy low during off-peak months and sell high when demand surges, maximising your ROI.

Combined with the BSR trend data (which shows sales velocity over time), the price history chart lets you assess both pricing stability and demand strength, two critical factors that determine whether a source is a reliable long-term winner or a risky one-time play.

SellerMagnet Sourcer provides a comprehensive competitor intelligence panel for every ASIN you analyse. This data is critical because understanding who you're competing against, and how they're positioned, directly impacts your sourcing and pricing strategy.

For each listing, the Sourcer shows:

• Total number of active sellers on the listing, broken down by FBA and FBM fulfilment type
• Current Buy Box holder and their price, fulfilment method, and seller rating
• Buy Box share percentage: how often each seller wins the Buy Box over a given period
• Lowest offer prices from both FBA and FBM sellers
• Estimated stock levels for competing sellers, helping you gauge supply saturation

This data helps you decide whether a listing is worth entering. A listing with 15+ FBA sellers and razor-thin margins is typically a poor sourcing candidate, while a listing with only two or three sellers and a healthy margin could be a great opportunity.

Once you've sourced a product and are actively selling, SellerMagnet's Repricer can use this same competitor data to automatically adjust your price and win the Buy Box more often.

The SellerMagnet Chrome Extension is officially supported on Google Chrome and all Chromium-based browsers, including Microsoft Edge, Brave, Opera, and Vivaldi. Since these browsers share the same extension architecture, the extension installs and runs identically across all of them. It is not currently available for Firefox or Safari.

In terms of Amazon domain support, the extension works on every Amazon marketplace that SellerMagnet covers, including Amazon.com, Amazon.ca, Amazon.com.mx, Amazon.co.uk, Amazon.de, Amazon.fr, Amazon.it, Amazon.es, Amazon.nl, Amazon.se, Amazon.pl, Amazon.com.be, Amazon.ie, Amazon.com.tr, Amazon.co.jp, Amazon.com.au, Amazon.sg, Amazon.in, Amazon.ae, Amazon.sa, and Amazon.com.br. When you visit any product page on these domains, the extension automatically overlays sourcing data, including the profit estimate, competitor count, Buy Box status, and price history, directly on the page.

This means you can evaluate products without leaving the Amazon website. Whether you're browsing category best-seller lists, scanning competitor storefronts, or checking a specific ASIN, the data appears instantly in a non-intrusive overlay panel.

The extension is included at no extra cost with every SellerMagnet subscription and can be installed from the Chrome Web Store in under a minute.

Yes. SellerMagnet Sourcer supports bulk ASIN analysis, allowing you to evaluate large numbers of products efficiently. You can upload a CSV file or paste a list of ASINs (up to 500 at a time) directly into the bulk analysis interface, and the system will process each one automatically.

For every ASIN in your batch, the Sourcer returns the same comprehensive data you'd get from a single lookup: profit calculations (with full fee breakdown), competitor data, Buy Box status, price signals, and product details. This means you can evaluate an entire supplier price list in minutes rather than hours.

Results from bulk analysis can be exported as CSV or Excel files for further analysis, filtering, or sharing with team members. Many sellers use these exports to build sourcing databases, compare supplier catalogs, or create internal reports on product viability.

Bulk analysis is especially valuable for wholesale sellers evaluating supplier price lists, agencies managing multiple product catalogs, and resellers processing large volumes of potential sourcing candidates on a regular basis.

Yes. When you look up an ASIN, the Sourcer checks whether the product is gated (restricted) in your seller account's category approvals. It flags items that require ungating, whether that's brand approval, category approval, or condition-specific restrictions, so you know immediately if you can actually list and sell that product.

This is a critical feature because sourcing products you can't list on Amazon wastes both time and money. Without restriction checks, sellers often discover gating issues only after purchasing inventory, leading to dead stock or the need to sell at a loss on other channels.

Restriction data is marketplace-specific, which is an important distinction. A product that is gated on Amazon.de may be completely open on Amazon.it or Amazon.es. The Sourcer reflects these differences based on the marketplace you've selected, so you can identify cross-border opportunities where a product is restricted in one market but freely sellable in another.

Combined with the profit calculator and competitor analysis, restriction alerts give you a complete go/no-go picture before you invest a single euro in inventory.

SellerMagnet will send you a reminder email a few days before your trial ends, so you'll always know when your billing cycle is about to begin. You can manage or cancel your subscription at any time from your account settings.

If you have questions about which plan is right for you, our support team is available to help you choose the option that best fits your selling volume and business model.

Yes. SellerMagnet supports connecting multiple Amazon Seller Central accounts to a single SellerMagnet subscription. This is particularly valuable for agencies managing multiple brands, sellers operating separate accounts for different marketplaces, or business owners with distinct legal entities selling on Amazon.

The number of connected accounts depends on your plan tier. The Starter plan supports one Seller Central account, while the Professional and Enterprise plans allow multiple connections. Each connected account has its own dashboard, fee calculations, and marketplace-specific data, so there's no cross-contamination of information between accounts.

For the Sourcer specifically, multi-account support means you can evaluate products in the context of each account's specific marketplace and fee structure. If you sell under one brand on Amazon.de and another on Amazon.com, you can switch between accounts and see the correct profit calculations for each.

If you manage a large number of seller accounts, our agency solutions offer enhanced multi-account management with team collaboration features. See the pricing page for details on account limits per plan.

SellerMagnet offers significantly more value per euro than standalone alternatives because it bundles sourcing, repricing, listing optimisation, review management, inventory tracking, and alerts into a single subscription. Competing tools typically charge for each of these as a separate product or tier.

For context: standalone product-research tools typically cost $29–$79/month and focus primarily on keyword data or price tracking. A separate price-history tool runs approximately €20/month but only provides charts without profit calculations, repricing, or listing tools. If you combined a research tool + a repricer + a listing optimiser + a review tool, you could easily spend $150–$250 per month on separate subscriptions.

SellerMagnet's subscription plans start at a fraction of that cost and include every tool in the platform with no per-lookup limits. This makes SellerMagnet especially attractive for small-to-medium sellers who need a complete toolkit but don't want to pay for four or five separate SaaS products.

You can compare plans and features on the pricing page, or start a free trial to experience the full platform before committing.

Yes. All sourcing analysis data can be exported in CSV and Excel formats. This includes product details, profit calculations (with full fee breakdowns), competitor data, price history snapshots, and Buy Box share data. Exports are available from both the single-ASIN dashboard view and bulk analysis results.

Many sellers use these exports to build sourcing databases, share analysis results with team members, or import data into their own inventory management spreadsheets or ERP systems. The export format is clean and structured, making it easy to filter, sort, and analyse in any spreadsheet application.

For teams and agencies, exports are particularly useful for collaborative decision-making. A sourcing specialist can run bulk analysis, export the results, and share them with a purchasing manager or client for review, all without requiring the reviewer to log into SellerMagnet.

API access for automated data retrieval is available on Enterprise plans, enabling integration with custom internal tools, dashboards, or automated sourcing pipelines.

No. SellerMagnet does not impose daily or monthly limits on the number of ASINs you can analyze. Whether you look up 10 products or 10,000, there are no usage caps, credit systems, or throttling. This unlimited access applies to all subscription plans: Starter, Professional, and Enterprise.

This is a significant differentiator from many competing tools that either limit the number of product lookups per day, charge per-query credits, or lock unlimited access behind their most expensive tiers. With SellerMagnet, unlimited ASIN analysis is a core feature available from day one on every plan.

The only practical limit is the API response time, which is under 5 seconds per individual lookup. This means you can realistically analyze hundreds of products per hour through the dashboard, and even more using the bulk analysis feature (which processes up to 500 ASINs per batch).

For high-volume sellers and agencies that need to process thousands of ASINs regularly, the bulk analysis and export features combined with unlimited lookups make SellerMagnet one of the most cost-effective sourcing tools available.
