Most companies monitoring competitors on marketplaces scrape websites — because it's easier. But a marketplace website is a storefront optimized for SEO and page load speed. The mobile app is an operational channel through which the buyer interacts with real warehouse, logistics, and pricing data. These are different layers of the same system, and they contain different data.

Research shows that users spend less than 6% of smartphone screen time in a browser — everything else happens in apps. That's where marketplaces send the most current data, personalized offers, and exclusive content. Companies building competitive analytics solely on website data systematically miss part of the market picture.

Why the App Knows More Than the Website

When a user opens a marketplace website, the browser receives an HTML page — it may have been generated and cached by a CDN several hours ago. The data in it is static until the next cache invalidation.

When a user opens the mobile app, it makes a direct request to the marketplace's operational servers: "Show me products for my address, my profile, right now." The response contains data the server generates specifically for this user, at this geolocation, at this second. No cache — just the current state of the system.

This architectural difference is not an implementation detail — it's a fundamental difference in data type. The website is optimized for broad reach: it must load fast for everyone. The app is optimized for the conversion of a specific user: it shows exactly what is most likely to drive a purchase here and now. That's why marketplaces route to the app data they never expose on the public website — and why monitoring only the website means working with an intentionally simplified version of reality.

8 Types of Data Found in the App but Not on the Website

1. Geo-Localized Prices

App prices depend on your address. Wildberries, Samokat, Yandex Lavka — all major services vary prices by warehouse and region. The website shows an averaged or "base" price. The app shows the real price for your delivery point. The difference can reach 5–15% on the same item.

2. Actual Stock per Warehouse

The website shows a status: "in stock" or "out of stock." The app knows and returns the exact unit count at a specific warehouse or dark store. This is what lets you catch the moment a competitor goes out of stock — a window of opportunity for repricing or ramping up advertising.

3. Personalized Promotions

Some discounts and promotions are launched for specific user segments: new customers, users with a specific purchase history, loyalty program members. These don't appear on the website — they exist only in the app for a selected audience. A competitor may be selling cheaper to your customer without you knowing.

4. Flash Sales via Push

Short-term discounts — lasting a few hours or until stock runs out — are launched through push notifications. They exist only in the app and are never indexed on the website. Website monitoring doesn't capture these events: they pass unnoticed by any web scraping system.

5. Hidden SKUs

Some product positions aren't indexed by search engines or displayed on the web page — they're accessible only through the app. These may be mobile-exclusive items, limited assortment positions, or products in testing. Web scraping won't see them.

6. Buyer's Personal Price

Wildberries and Ozon apply loyalty discounts calculated individually, affecting the final price shown in the app. Ozon removed this parameter from its API in 2024. The real price a buyer sees is only accessible from the app — not the API, not the website.

7. Regional and Local Promotions

City- or region-specific promotions — like a discount celebrating a new warehouse opening or a local promo day — are launched in the app with geo-targeting. On the website they either don't appear or show without regional context.

8. Real-Time Delivery Data

Delivery time in the app is calculated dynamically: by warehouse load, courier availability, and buyer's address. For quick-delivery services — Samokat, Yandex Lavka — this shows the competitor's real operational situation. The website doesn't provide this.

Three Scenarios Where App Data Changes the Outcome

Repricing based on the buyer's real price. A marketplace seller sees a competitor's website price of 1,543 ₽ and sets their own at 1,540 ₽ — looks competitive. But the Wildberries app, with geolocation set to a specific Moscow district, shows that same item at 1,319 ₽: a personal loyalty discount and a local flash sale are active. Repricing on website data runs in circles — the buyer sees completely different numbers. The pricing gap stays invisible until the app becomes the data source.

Stock monitoring to manage advertising spend. A brand wants to know when a key competitor goes out of stock in a specific region. The website shows "in stock" until almost the very end — warehouse status is delayed by CDN cache for several hours. The app shows "3 units remaining at the warehouse" a full day before the product disappears. Knowing this in advance, the brand ramps up regional ads before the competitor's shelf goes empty — not after.

Operational intelligence for quick commerce. A fast-delivery service pulls daily data from Samokat's app across 50 dark stores: promised delivery times, stock levels in key categories, active local promotions. A month of analysis shows that on Saturdays the competitor's delivery times increase and dairy assortment drops — a clear operational bottleneck. That's a signal for a targeted ad campaign on exactly those days and in exactly those neighborhoods.

Who Loses This Data — and What It Costs

  • Marketplace sellers — can't see real competitor prices with loyalty discounts and personalized promotions applied, so repricing is built on incomplete data.
  • Category managers — miss competitor flash sales, fail to react in time to regional price changes.
  • Brands and manufacturers — can't see the real shelf price of their products at different retailers with all buyer discounts applied.
  • FMCG analysts — build reports on website data that may diverge from reality by 5–15% due to geo-localized pricing.
  • Quick-delivery services — don't track competitors' operational situation: dark store stock levels, delivery times, local promotions.

The cumulative effect is not just missing data — it's a systematically distorted picture of the market. Pricing strategy, promotional calendars, production planning — all built on data that's partially unavailable to anyone analyzing websites alone. Switching to the mobile app as a data source closes that blind spot.

How to Get This Data from the App

1. Define the Task

You specify which data you need: geo-localized prices, stock levels, promotions. You indicate the apps, regions, and update frequency.

2. We Collect the Data

The system reads data directly from the mobile app — with the right geolocation, at the right time, bypassing CDN cache and official API restrictions.

3. You Get the Results

Data in JSON, CSV, or Excel — on a schedule or one-time. A complete market picture instead of an averaged storefront.
