How to Scrape Marketplace Seller or Vendor Listings
Use ProfileSpider to turn marketplace seller and vendor listings into a structured lead list. Open the marketplace page in Chrome, extract visible sellers, save them to a list, enrich missing details, and export to CSV, Excel, or JSON.
Goal
What This Workflow Is For
Turn marketplace seller and vendor listings into a clean, structured list you can qualify, enrich, and export.
Use this workflow when an online marketplace lists sellers, stores, or vendors and you want that data in a spreadsheet, for example sellers in a category, top-rated stores, or vendors in a region. Marketplace listings are high-intent because each seller is an active business with products, ratings, and store pages.
Whether you sell services to marketplace sellers, recruit them as partners, or research competitors, ProfileSpider reads the visible listings and turns them into structured rows you can qualify and export.
This page is focused on the ProfileSpider workflow: open the marketplace listing page in Chrome, extract the visible sellers, save the rows to a list, optionally enrich missing details, and export the list as CSV, Excel, or JSON.
Prerequisites
Before You Start
Confirm the page and tooling match this workflow.
Before you start, make sure you have:
- ProfileSpider installed in Chrome and signed in
- A public marketplace category, search, or seller listing page open in a normal Chrome tab
- Seller, store, or vendor listings, cards, or rows visible on the page
- A rough idea of the columns you want, such as seller name, store, category, rating, website, location, and source URL
This workflow works best when the marketplace shows repeated seller listings in live HTML. Always follow the marketplace terms and only extract data you can access normally in your browser.
Fit
Best For / Not Ideal For
Set expectations before you install or run an extract.
Best for
- Marketplace category and search listing pages
- Seller, store, and vendor profile listings
- App, plugin, and integration marketplace listings
- Service marketplace provider listings
- Top-rated or featured seller pages
- Regional or niche marketplace vendor pages
Not ideal for
- Seller data behind a login or account you are not authorized to access
- PDFs, screenshots, or images of listings with no live HTML
- Pages that only show product images without seller details
- Pages where listings only appear after complex in-page interactions
- Single-product pages with no repeated seller rows
Steps
Step-by-Step Workflow
- 1
Open the marketplace listing page in Chrome
Go to the public marketplace category, search, or seller listing page and wait until the listings are fully loaded and visible.
Apply category, rating, or location filters before extracting so you capture the sellers that match your target.
- 2
Open ProfileSpider
Click the ProfileSpider extension icon. The extension will analyze the current page and prepare the extraction workflow.
- 3
Review the fields you want to capture
Common fields for marketplace listings include seller or store name, category or product, rating or reviews, website or store URL, location, and source URL.
ProfileSpider structures the data visible on the page. Fields the marketplace does not publish, such as direct emails, may remain empty.
- 4
Run the extraction
Start the extraction. ProfileSpider turns the repeated seller listings on the page into structured rows. A normal page scrape uses one credit.
- 5
Save the sellers to a list
Save the extracted rows to a new or existing list. Use tags or notes to record the category, region, or research project.
For example, save rows to a list named “Home decor sellers - EU” or “Top-rated analytics vendors”.
- 6
Enrich and export the seller list
Review the rows, remove anyone outside your target, and enrich missing details such as websites or contacts where useful. Export the saved list as CSV, Excel, or JSON for outreach or research.
Schema
What ProfileSpider Extracts
Default fields for this workflow. Add or remove columns before you extract.
- Seller / Store NameThe seller, store, or vendor name shown in the listing.
- Category / ProductThe product type, service, or category the seller offers when listed.
- Rating / ReviewsStar rating, review count, or sales volume when the marketplace exposes it.
- Store / Website URLThe seller store page or external website linked from the listing, when available.
- ContactA named contact or store owner when the listing exposes one.
- EmailAn email address if it is visible on the page. Missing emails can be handled later with email finding where available.
- LocationCity, region, or country when present in the listing.
- Source URLThe marketplace listing page the row came from, useful for verification and deduplication.

Troubleshooting
Common Problems
The marketplace paginates or uses infinite scroll
Extract each page or scroll until the sellers you need are loaded, saving each batch to the same list, then deduplicate before export.
Listings show stores but no contacts
Save the seller rows first, then enrich the store or website URL to add contact information, or open the store page and extract details into the same list.
Emails are not shown
Marketplaces rarely expose seller emails. Save the visible data first, then use email finding where available once you have a store name and website.
The same seller appears in multiple categories
Sellers often list across categories. Review duplicates inside the saved list and keep the source URL for verification.
The marketplace blocks scraping or hides content
Only extract data you can access normally in your browser and follow the marketplace terms. If the visible page contains little useful data, extraction may be limited.
