We can take the first stage - check the possibility of automated data collection, gather a test database of sellers, and show which fields can be reliably obtained.

We have worked with marketplaces and e-commerce on tasks related to data collection, catalogs, sellers, products, prices, stocks, ratings, categories, links, quantities of products, contact and public business fields - if they are open and accessible without violating the platform's rules.

> What I would do at the start
>> define the list of marketplaces and technical limitations for each
>> check available fields - seller name, link, categories, rating, quantity of products, product pages, other open data
>> gather a test sample and structure the database
>> prepare the logic for updating, deduplication, and data quality control

Hello. The task is clear; automating the collection of such data is entirely possible (through marketplace APIs or web scraping with bypassing block protection).

Answers to your questions:

Experience with marketplaces: I have worked with parsing Prom, Rozetka, OLX, as well as foreign Amazon and Allegro.

Data I can collect: Company/seller name, store link, contact details (if they are publicly available/in the profile), rating, number of reviews, assortment volume (number of products), main categories, and current status (active/inactive).

Project examples: I collected a supplier database from Prom.ua by categories with export to Google Sheets, and also monitored prices and product availability among competitors on Rozetka.

I will answer your questions point by point:

1. Which marketplaces I work with:
I have experience parsing Wildberries, Ozon, AliExpress, Rozetka, Prom, and Amazon. Separate algorithms are written for each platform using Python (Requests, Scrapy, Playwright) and proxy rotation to bypass blocks.

2. What data can be obtained:

Hello! I specialize in data parsing and structuring — I can gather open information about sellers and create a database in your format (Excel/CSV/Google Sheets or directly in a database).

Marketplaces: I have worked with OLX, Prom, Rozetka — I parsed listings, prices, seller data. I will adapt my approach to the platform you need.

The data I can realistically extract from open pages includes: seller name, profile link, categories, rating and number of reviews, number of products, registration date — plus everything else that is publicly available. First, I will create a small test sample so you can see which fields can be realistically collected from your platform, and then we can finalize the database structure.

Please clarify: (1) which specific marketplaces and (2) is this a one-time extraction or do you need periodic updates of the database? This will affect the exact estimate.

I am starting at a low price — I am gathering my first reviews on Freelancehunt, so I am offering a good deal. I am ready to show a live demo of the parsing in the chat.

Good day, Olga! Parsing marketplaces is my specialty (Python, automated data collection + structuring).

Regarding your points:
• Experience: I have collected public data from large trading platforms — seller catalogs, product cards, listings (via API where available, otherwise careful page parsing).
• Data I extract: seller name, profile link, categories, rating/reviews, number of products + other public fields from the seller's page (exact list will be determined for each specific platform).
• Result: structured database (CSV / Google Sheets / DB) + honest assessment of the possibilities and limitations of automation for each platform (limits, anti-bot measures, volume).

I suggest starting with a brief technical analysis of the selected platforms — I will provide a precise plan, fields, and timelines without guesswork. Please let me know which marketplaces are a priority and the approximate volume (how many sellers)? I will show examples of my work in our correspondence.

I have my own ready-made parsers in Python (requests + BeautifulSoup) — I have already implemented data collection from Work.ua (vacancies), Auto.ria (cars), and SvitBudov (real estate): name, price, location, link, deduplication by URL. I can show the code or an example of the exported JSON.
These platforms do not have complex anti-bot protection, so the tasks are technically similar. If your marketplaces have captcha/Cloudflare — I also have experience bypassing it through Playwright on another project, and I can adapt the approach.
I suggest starting with a test sample: 15-20 sellers from one platform, I will show a real list of fields that are consistently collected, and the format (Excel/CSV/JSON). After that, we can agree on the full scope.
Please clarify: which specific marketplaces and is it a one-time export or do you need regular updates?

Hello, Olga!

I have experience in automated data collection and building structured databases (Python, API/HTML parsing, exporting to Excel/Sheets or a database).

To accurately assess the volume and choose the right approach, please clarify:

1. Which specific marketplaces are you referring to (Rozetka, Prom, OLX, others)?
2. What is the purpose of the seller database — market analysis, finding potential partners, or something else? This will help understand which fields are truly needed and which are excessive.
3. Estimated volume — how many sellers do you plan to collect, and do you need a one-time export or ongoing database updates?

Hello, Olga!
I have direct experience in parsing marketplaces and can show it. Structuring the extracted data into a clean database is my daily work.
Let me be honest about the main point right away. The feasibility depends on which specific platforms you are interested in. For some, sellers are willing to share data easily, while others have captchas and limits on each request. Therefore, I do the collection defensively by default: controlled request pace, retries on failures, deduplication on records. This is to ensure the database is collected steadily and doesn't get banned after ten minutes.

The fields that can realistically be obtained from open pages include: seller name, profile link, categories, rating, number of products and reviews, often the registration date. As for closed fields, such as private phone numbers or emails, I will be honest. If they are not publicly available, I won't promise what is physically not there. I will not sell non-existent data.

One point about volume. One hundred sellers and half a million are different tasks in terms of complexity. If you have an approximate idea of the number, the estimate will be more accurate.

I offer a free trial. You name one platform, I will take a few sellers and show you a ready table with the real fields that I managed to collect. This way, you will immediately see if automation is possible and what specific data can be obtained, even before starting the main work. This directly answers your question about the possibility of collection.

Good day!

I create parsers for data collection, so straight to the point — the main thing here is not to "scrape," but how consistently a specific marketplace allows this to be done.

Regarding the data: seller name, profile link, categories, rating, number of products and reviews, registration date, sometimes contacts/location — everything that is publicly available on the seller's page can be collected and structured (CSV / Google Sheets / database).

What determines the "possibility of automation" is the protection of the specific platform. Some provide data freely, while others have captchas and limits on each request. Therefore, my approach is protective by default: controlled request pace, retries with backoff, deduplication on record — to ensure the collection lasts long and doesn't fail after 10 minutes due to a ban. An example of this logic (throttling, retries, dedup) in code: github.com/novellocaitlin13-ui/async-scraper.

Regarding experience with platforms — I have worked with scraping marketplaces and classifieds. But to be more honest: name your target marketplace and approximate number of sellers — and I will respond with which fields can realistically be obtained, how complete the coverage will be, and whether there is protection that complicates things. Which one shall we start with?

It is necessary to gather a database of sellers from marketplaces in a structured format. Approach: Python + Playwright or requests depending on whether the page is rendered by the client; parsing fields such as name, link, categories, rating, number of products, and everything that is publicly available; output in Excel/CSV or directly into a database. Key risk: anti-bot protection on Rozetka, Prom, Amazon, etc., so implement proxy rotation and bypass rate limits to prevent the parser from breaking silently.

Which specific marketplaces are you interested in and approximately how many sellers need to be gathered?

Hello! Parsing, cleaning, and structuring large datasets is my specialty as a Python engineer. I implement stable, fast, and fully automated data collection solutions "turnkey."

Clear answers to your questions:

Experience with marketplaces: I have successful experience in parsing large e-commerce and classified platforms (including Rozetka, Prom, OLX). I can bypass content scraping protection (Cloudflare, CAPTCHAs, IP blocking) using proxy rotation and simulating real user actions.

What data I will collect and structure: A complete range of open markers: seller/store name, direct link to the profile, category/niche of products, current rating, number of reviews (positive/negative), total number of products available, as well as contact details (phone, email, social media), if they are publicly available.

Technical stack and format: I write scripts in pure Python using asynchronous libraries (for maximum collection speed). I clean and structure data using Pandas. I will provide the final database in any format convenient for you: Excel (XLSX), CSV, or I can directly integrate it into a database (PostgreSQL/SQLite).

Hello! I am currently creating a parser for myself, but not only for collecting information from the page, but also for searching for all possible data (I currently need all social networks, contacts, and websites). The search for companies based on specified parameters from Google Maps, Instagram, and Prom is already working, and I plan to add other directions. Right now, I am fine-tuning the data search process. I can expand it according to your requests, and we can agree on payment terms that are beneficial for both of us. Alternatively, I can simply gather the necessary information for you once. Or a full-fledged tool. Whatever you choose, the price and deadlines will be accordingly 😉

Good day. The task is clear: to gather and structure open information about sellers from marketplaces and to form a database from this, and first to assess whether this can be automated for specific platforms.

Data collection is my main area. I have worked with scraping in Python (Selenium, Playwright, requests plus parsing), with proxies and bypassing simple anti-bot protection, and with structuring the results into a clean database or table. Typically, I can reliably extract: seller name, profile link, categories, rating and number of reviews, number or assortment of products, registration date, and contacts if they are available in the public profile. What can be extracted depends on the specific marketplace, so as a first step, I will look at one or two of your target platforms and tell you exactly which fields are consistently available and where protection will make data collection more expensive.

Which specific marketplaces are we working with and what approximate volume of sellers is needed in the database? This will affect both the approach to data collection and the timelines.

We already have a practically ready similar solution for collecting open data from marketplaces, which can be quickly adapted to your sources and launched =)
We can discuss the details here; I am available.
I see the initial phase lasting 7 days and costing 18,000 UAH - checking 1-2 marketplaces, collecting a prototype, structuring the database, exporting to a table or database, and a brief conclusion regarding scaling.
We have worked with Rozetka, Prom, Shopify, WooCommerce, OpenCart, XML and YML product feeds, price synchronization, stock levels, categories, and product cards.
From open fields, we can usually obtain the seller's name, link, categories, rating, number of products, reviews, city or region, public contacts if available on the page, collection date, and technical status of the check.
The implementation scheme is simple - first, we check data availability and platform limitations, then we perform collection, cleaning, deduplication, storage, and quality control.
Next, we can add AI for classifying sellers, searching for potentially interesting niches, and prioritizing leads - it seems to fit well with your task.
First question - which marketplaces and categories are a priority for you?
Second question - do you need a one-time database or regular updates?
