If you sell online, run a marketplace, or advise e-commerce clients, you already know why eBay matters: it’s one of the few places where big retailers compete side by side with thousands of small merchants and private sellers. It is noisy, fast, and incredibly informative.
But treating eBay as your only source of marketplace data is a strategic blind spot. Pricing moves first on Amazon and Walmart. Cross-border supply often starts on AliExpress. Niche demand shows up on Etsy. Consumer-to-consumer dynamics unfold on Mercari. Regional marketplaces like Allegro can completely reshape what “competitive price” means in that country.
In other words: if you only scrape eBay, you are seeing one slice of the market, not the whole picture.
In this guide, we will look at six marketplaces that behave like eBay from a data perspective – multi-seller, competitive, dynamic – and are worth scraping alongside it: Amazon, Walmart, AliExpress, Rakuten, Etsy, and Mercari. All of them are already supported by ScrapeIt as fully managed scrapers, alongside eBay itself.
If you need a bigger view of what we do for online retail, you can always start on our Ecommerce Data Scraping Services page. If you are specifically interested in eBay, there is a dedicated eBay scraper.

If you operate a marketplace or comparison engine, your job is to show buyers the best offers – which means understanding pricing, discounts, and assortment on rival platforms:
Scraping “eBay-style” marketplaces lets you build a cross-platform product feed that your BI tools, merchandising team, and sales team can all use.
For direct-to-consumer brands and online stores, marketplaces are both competitors and demand signals:
Here, marketplace scraping is an input into pricing tools, PIM systems, and assortment planning – the kind of workflows that Ecommerce data scraping services are designed to power.
If you build models or reports for others, you need breadth:
Using managed scrapers for multiple marketplaces lets your team focus on analysis, not crawling. You define the schema and cadence; ScrapeIt maintains the extraction layer.
Finally, there is the arbitrage use case – buying low on one platform and selling higher on another:
Here, frequency and speed matter more than historical depth: you want fresh snapshots, often multiple times per day, something ScrapeIt supports across all the marketplaces listed in the Popular Sites We Scrape catalogue.
Each marketplace looks different on the surface, but the high-value data layers are similar. When we design an engagement via ecommerce data scraping services, we usually work across the following layers.
All these fields can be combined into a single schema and delivered in your preferred format (CSV, JSON, Excel) through ScrapeIt’s managed extraction, exactly as described on ecommerce data scraping services.

Amazon is the obvious counterweight to eBay. It is the world’s largest e-commerce platform by revenue, mixing first-party retail with a massive marketplace of third-party sellers. For many categories and regions, Amazon defines the reference price that everyone else reacts to.
ScrapeIt runs a dedicated Amazon scraper that is used by marketplaces, brands, and market research teams to monitor prices, availability, and product performance at scale.
If Amazon is a major input in your pricing or catalog decisions, it is worth reading the dedicated blog article linked from the Amazon scraper page, which covers its specific challenges in more depth.

Walmart is both a giant retailer and a fast-growing online marketplace. For U.S. mass-market categories – groceries, household goods, general merchandise – Walmart’s prices and promotions strongly influence what consumers expect to pay.
ScrapeIt offers a tailored Walmart data scraper that collects product information, prices, reviews, and availability in a format suited to your systems.
For clients who want an integrated view of U.S. retail, we often combine Walmart data with Amazon and eBay feeds and deliver a unified dataset via the workflow described on ecommerce data scraping services.

AliExpress is the world’s largest B2C marketplace for cross-border shopping, connecting mostly Chinese sellers with buyers around the globe. For many categories, it is where new products, designs, and suppliers appear before they are picked up by western brands and marketplaces.
Our AliExpress scraper is built for teams that want to monitor global supply, dropshipping trends, and early-stage demand signals.
Our experience building the AliExpress data scraper is often used as the template for other dynamic marketplaces listed under Popular Sites We Scrape, such as Shopee, Tokopedia, or Flipkart.

Rakuten is one of Japan’s leading marketplaces and a key player in several other Asian markets. It blends traditional marketplace structure with a strong loyalty program and coupon ecosystem, which makes it a powerful source of regional price and promotion data.
The Rakuten data scraper from ScrapeIt focuses on extracting those loyalty- and promotion-driven nuances that standard product feeds tend to miss.
For clients already collecting data from Amazon, Walmart, and eBay through our e-commerce scraping services, adding Rakuten scraping is a pragmatic way to extend coverage into Japan and adjacent markets without changing their internal analytics stack.

Etsy is where handmade, vintage, and creative products live. It is not a mass-market retailer; it is a marketplace of ideas and micro-brands. For categories like jewelry, home decor, print-on-demand, and digital templates, Etsy often provides better competitive and trend insight than eBay or Amazon.
Our Etsy scraper focuses on the fields that make or break a listing in Etsy’s search and discovery algorithms: titles, tags, materials, photos, and reviews.
Because Etsy sits closer to the “long tail” of demand, data collected via the Etsy scraper is frequently used as training material for recommendation and search models, often alongside more standardized data from Amazon and eBay fetched via ecommerce data scraping services.

Mercari is one of the leading consumer-to-consumer marketplaces in Japan and the U.S. It is particularly important for second-hand fashion, electronics, collectibles, and everyday items. If eBay is your benchmark for secondary market prices, Mercari is the logical second source.
The Mercari scraper from ScrapeIt collects structured product, seller, and pricing data from Mercari’s web interface, giving you a second lens on resale and circular-economy behavior.
When combined with eBay data via the eBay scraper, Mercari data gives traders, marketplaces, and analytics teams a far more robust picture of what second-hand products are really worth in different regions.
Global platforms are only half the story. In many countries, regional marketplaces dominate everyday consumer behavior and pricing. ScrapeIt already supports dozens of these platforms; a few important examples:

Allegro is effectively “eBay + Amazon” for Poland and parts of Central Europe. For categories like electronics, household goods, and automotive, it is the primary reference marketplace.
ScrapeIt not only runs an Allegro scraper, but also maintains a full production pipeline documented in the case study The Lowest Allegro Prices from 150K EANs Collected, where 150,000 EANs are searched daily to deliver the lowest marketplace price per SKU.
In addition to the global “eBay-style” platforms covered above, ScrapeIt supports a wide range of regional marketplaces, including (among others):
In practice, most sophisticated clients mix global and regional sources into a custom basket that matches their footprint and goals.
If you rely on marketplace data to make decisions, eBay is essential – but incomplete. Serious e-commerce and retail teams treat it as one signal among many. Amazon, Walmart, AliExpress, Rakuten, Etsy, and Mercari provide their own slices of reality: mass-market pricing, cross-border supply, regional tastes, creative trends, and second-hand liquidity.
Scraping these “sites like eBay” in a structured, continuous way is what turns them from noisy websites into reliable market intelligence. With ScrapeIt, you do not have to own the crawling infrastructure – you just define the marketplaces, the fields, and the rhythm, and our team delivers ready-to-use datasets.
If you want to explore how this could work for your marketplace, brand, or client portfolio, start with ecommerce data scraping services or browse the individual scrapers for eBay, Amazon, Walmart, AliExpress, Rakuten, Etsy, and Mercari. From there, it is a short step to a pilot dataset that shows you what multi-marketplace visibility really looks like.
1. Why shouldn't I rely on eBay as my only source for marketplace data?
eBay is informative, but it only shows one slice of the market. Key pricing signals often move first on platforms like Amazon and Walmart, cross-border supply originates on AliExpress, niche demand appears on Etsy, and C2C dynamics unfold on Mercari. Scraping these "eBay-style" marketplaces provides a complete, multi-seller, competitive view of the market.
2. Which six specific marketplaces are recommended to scrape alongside eBay?
The six marketplaces recommended for their competitive, dynamic, and multi-seller nature are Amazon, Walmart, AliExpress, Rakuten, Etsy, and Mercari.
3. What types of businesses benefit most from scraping multiple marketplaces?
Four main groups benefit: Marketplaces and Price Comparison Sites (for benchmarking and recruitment); Online Stores, Brands, and Manufacturers (for price tracking, assortment gaps, and MAP monitoring); Consultancies and Market Research Firms (for breadth, historical data, and AI training); and Resellers/Arbitrageurs (for speed and finding mispriced assets).
4. What are the five main layers of high-value data that can be extracted from these marketplaces?
The data can be broken down into five layers:
1) Product and Catalog Layer (titles, attributes, media);
2) Pricing and Promotion Layer (current/original price, coupons, bundles);
3) Availability, Inventory, and Logistics Layer (stock status, delivery dates, shipping fees);
4) Seller, Review, and Trust Layer (seller ratings, reviews, badges);
5) Recommendation and Behavior Layer (similar items, bestseller rankings).
5. Besides the "Big Six," what other types of marketplaces should businesses consider scraping?
Businesses should also consider Regional "eBay-Style" Marketplaces that dominate specific areas, such as Allegro (Poland/Central Europe), eMAG, Wildberries (Eastern Europe), Shopee, Tokopedia, Lazada (Southeast Asia), and Flipkart (India), to ensure their data matches their specific geographical footprint.
