Marketplace Price Monitoring
who it's for

Who needs marketplace competitor price monitoring

Marketplaces have become the fastest-moving shelf in online retail. Prices and seller offers change several times a day. Without monitoring, you spot changes too late.

Marketplace sellers

Track competitor prices and stock across your category. Adjust your prices, ad bids, and listings in time.

Brands and distributors

Find every seller of your brand. Manufacturers see who undercuts prices and where gray-market supply comes from.

Category analysts

Size up category volume and structure: sellers, price segments, new-product dynamics. Know your market share.

SaaS tools and repricers

Get raw marketplace data via API to power your own products, tools, and algorithms.

service formats

Marketplace price monitoring: how the service works

Marketplace price monitoring is the automated collection of prices, discounts, stock levels, and product rankings across marketplaces. Every change is recorded with a date.

More than half of global online sales flow through marketplaces. Repricing algorithms rewrite prices several times a day. No manual process can keep up.

The service runs automatically:

  • the scraper crawls listings and categories on each site on a schedule;
  • data lands in a single database with full history;
  • alerts arrive the day a change happens;
  • exports flow into your spreadsheets and systems.

The result: a complete picture of the category for pricing, sales, and assortment decisions. This kind of monitoring protects both margin and market share.

Marketplace price scraping

The marketplace price scraper captures every price on a listing: base, discounted, and the final price shoppers see. Competitor and seller price scraping runs on a schedule: from a one-time snapshot to several pulls a day.

Marketplace-funded discounts are tracked too. We record both the seller's price and the price shoppers actually see. Offer comparisons stay honest, and reports never diverge from the storefront.

What we track: prices, sellers, rankings

We capture everything visible on a listing and in marketplace search results:

  • prices, discounts, promotions, and participation in sale events;
  • sellers and the Buy Box owner;
  • availability and stock by warehouse;
  • listing positions in search results and categories;
  • reviews, ratings, and shopper questions;
  • new listings and delisted products.

The Buy Box is the right to have your offer shown first when several sellers compete on one listing.

Deep review analytics is a separate service: product review monitoring with sentiment, topics, and negative-review alerts.

How do you track prices on marketplaces?

A working setup takes four steps:

  • build a list of listings, brands, or entire categories;
  • set the collection frequency: daily or more often;
  • receive data as a file, a feed, or via API;
  • set up alerts for undercutting and price changes.

Manual listing checks are fine for spot checks. A category with thousands of products needs automated collection. We handle the setup. A dedicated manager guides the project from request to data delivery.

Marketplaces worldwide

We cover all the major marketplaces: Amazon, Walmart, eBay, Etsy. Data comes from both websites and mobile storefronts. Niche and regional marketplaces are added on request.

We connect marketplaces in any country:

  • global: Amazon, eBay, AliExpress;
  • Poland: Allegro, the country's largest marketplace;
  • France: Cdiscount and ManoMano;
  • Germany: Zalando, Otto, and Kaufland;
  • Netherlands and Belgium: bol.com;
  • Romania: eMAG.

Monitoring prices on marketplaces in other countries helps when entering new markets. You see price levels, the seller landscape, and the strongest competitors. To prepare listings for a new country, use automated product listing translation.

Where to view product price history

Wherever your monitoring history is delivered:

  • exports with a date on every change;
  • your BI system or spreadsheet;
  • a web interface with charts for every listing.

We keep every snapshot. Pull a competitor's prices for any period, check seasonality, and see how the category responds to sale events.

The service is configured to your task: fields, collection frequency, alerts. Want to explore price history on real data? We'll give you demo access to the interface before the project starts.

Price monitoring for online stores and marketplaces

Can you monitor prices in online stores? Yes. An online store is scraped with the same methods: prices, promotions, availability, and assortment.

The mechanics differ. A marketplace platform adds its own layer: platform discounts, the Buy Box, promotion bids, stock by warehouse. For online stores, the catalog, promotions, and regional prices matter more.

That's why the two are separate services:

  • this page covers marketplaces;
  • online store websites are covered by a dedicated service: online store monitoring;
  • we don't collect in-store shelf prices: we work with open online data.

Chain locations and addresses are collected by a separate service: chain location lists. Retail solutions are gathered under data for retail.

Comparing prices across marketplaces and online stores

The same product sells everywhere at once: on marketplaces, in chain stores, direct from manufacturers. Prices diverge.

We link listings of the same product across marketplaces and stores. Price comparison becomes honest: SKU to SKU, offer to offer.

That linkage answers practical questions:

  • where the product sells cheaper: on the marketplace or the store's own site;
  • which sellers violate recommended prices;
  • how platform discounts change the final price for shoppers.

Matching large catalogs is a separate service: product matching. Enforcement of recommended prices is covered by MSRP and MAP monitoring.

Data for pricing and repricing

Monitoring gathers the facts. Then pricing begins: rules, guardrails, and responses to competitor moves.

A price index compares your price against the marketplace and market average.

Monitoring data powers:

  • repricing rules and price guardrails;
  • price indexes by category and brand;
  • reports for category teams;
  • margin and profit protection during sale events.

Marketplaces compare prices too. An overpriced listing can lose promotion, and with it, sales. Fresh data lets you manage prices without the manual grind.

Strategy is supported by market-data pricing together with competitor analysis.

questions & answers

Marketplace price monitoring FAQ

Can't find the answer you need? Send a request: we reply within one business day.

Which marketplaces do you work with?

We work with marketplaces worldwide: Amazon, Walmart, eBay, Etsy, Allegro, Cdiscount, Zalando, Otto, bol.com, eMAG. Niche and regional marketplaces are added on request.

How large a category can you track?

There are virtually no limits. We track categories of hundreds of thousands of listings with daily updates. Accuracy and completeness are guarded by automated checks.

Do you capture marketplace-funded discounts?

Yes. We record prices by type: base, seller-discounted, and the final shopper price. Each type sits in its own field, so the shopper price never gets mixed up with the seller price.

Can you track specific sellers?

Yes. We set up monitoring against a seller list — or find every seller of your brand automatically and watch for new ones.

How much does marketplace price monitoring cost?

Projects start at $150. The final cost depends on the number of marketplaces, listing volume, update frequency, and extra processing (see the factor breakdown above). An exact quote and a free data sample come before work starts.

How do you track prices on marketplaces?

For spot checks, people open listings and compare by hand. Real monitoring needs automated collection. A scraper crawls categories on a schedule, captures prices, discounts, and rankings, and stores the history. Data arrives as a file, a feed, or via API. For sellers, that saves hours of manual checks every day. The step-by-step outline is in the description above, and we handle the setup.

Where can I see product price history?

In your monitoring history. Every price is stored with its capture date. Trends show up in exports, your BI system, or a web interface with per-listing charts. Public price-history sites work for one-off checks on individual products. Working with an entire category takes monitoring of your own. Demo access to the interface is available on request.

Can you monitor prices in retail stores?

Yes. Retail chains' online storefronts are covered by a dedicated service: online store monitoring, including regional prices by city. We don't collect shelf prices inside physical stores: we work with data published online. Chain locations and addresses are covered by chain location lists, and retail solutions are gathered under data for retail.

Which system tracks competitor prices?

Three classes of tools cover the task. Off-the-shelf SaaS monitors work from a fixed list of marketplaces and plans. A marketplace's built-in analytics shows only its own platform. Custom monitoring collects data to your exact needs: any marketplaces, fields, and frequency. We do the third and deliver data as a service: as a file, a feed, or via API. We take the work on ourselves, and our scraping tools overview helps compare the approaches.
