Through the eyes of the competition: how proxies help businesses monitor market prices and product ranges

how proxies help businesses monitor market prices and product ranges

In today’s digital economy, dynamic pricing and rapid changes to product ranges have become the norm. Major retailers, marketplaces and e-commerce platforms review product prices several times a day. To remain competitive, maintain profit margins and respond promptly to price dumping, businesses need continuous, automated market monitoring.

However, manually collecting data across thousands of product listings is impossible, and traditional automated parsing (web scraping) faces fierce resistance from security systems. Competitors’ websites instantly recognise repetitive requests from a single IP address and block them.

The solution to this problem lies in the use of a specialised network infrastructure. In this article, we will examine in detail how proxy servers help businesses analyse the market legally and without hindrance, why website security blocks standard requests, and how to properly integrate proxies into a company’s analytical processes.



Why do businesses need to monitor prices and product ranges?

Before moving on to the technical side of the matter, it is important to understand the commercial value of regularly analysing competitors. Collecting up-to-date data solves several strategic tasks at once:

  • Pricing Management. By knowing the exact prices of similar products offered by competitors, a company can configure algorithms for automatic price recalculation (repricing). This ensures that the company does not lose profit by selling too cheaply, nor does it lose customers by setting prices too high.
  • Assortment Analysis (Assortment Intelligence). Monitoring enables the tracking of new product launches, the identification of market shortages, and the optimisation of a company’s own stock levels.
  • Tracking promotions and marketing activities. Analysing price changes helps to identify hidden sales, seasonal discounts, or the launch of large-scale marketing campaigns by competitors in good time.
  • Monitoring of RRP (Recommended Retail Price). For manufacturers and distributors, web scraping is a way to ensure that retail partners and dealers do not engage in price dumping and adhere to the brand’s pricing policy.

Website security architecture: why direct scraping is doomed to fail

Attempting to run a scraping script or specialised software from your company’s static IP address will almost certainly fail. Major e-commerce platforms invest millions in anti-fraud systems, WAFs (Web Application Firewalls) and bot protection.

When security algorithms detect that 100, 500 or 1,000 requests per minute are coming from the same IP address, they classify this behaviour as anomalous. A normal person is physically incapable of browsing pages at such a speed. As a result, the website applies protective measures:

  1. CAPTCHA prompt. The script fails the verification and stops collecting data.
  2. Data tampering (speed rating/fake reviews). The system begins to provide the parser with incorrect prices or inaccurate stock information, misleading analysts.
  3. Complete block (IP ban). Access to the resource from your IP address is completely blocked.

To circumvent these restrictions, automated software must mimic the behaviour of hundreds or thousands of real users accessing the site from different parts of the world or regions within the country. This is precisely the task that proxy servers fulfil.

How proxies ensure continuous data collection

A proxy server acts as a protective intermediary between your analytics software and the target web resource. When a script makes a request to a competitor’s website, this request passes through the proxy server. As a result, the target site sees only the proxy’s IP address, geolocation and network parameters, whilst your company’s actual data remains completely hidden.

To build a fault-tolerant data collection system, businesses use three main mechanisms implemented via proxies:

IP address rotation as protection against blocking

The key principle of successful monitoring is the constant rotation of network addresses. If you send a stream of 10,000 automated requests via a single IP address, the website’s security algorithms will block it instantly. However, if you distribute the same volume of requests across a pool of 500 different IP addresses, each individual proxy will only handle 20 requests. To WAF (Web Application Firewall) security systems, this will appear as perfectly natural traffic from ordinary retail customers visiting the site simultaneously.

In addition to reducing the frequency of requests per IP, rotation solves a number of other critical tasks:

  1. Simulation of real behaviour: Each new address generates a unique network session, obscuring the parser’s automated trail.
  2. Bypassing CAPTCHAs: If one of the IP addresses in the pool does encounter a bot check, the monitoring system instantly switches the traffic to the next clean proxy without interrupting the workflow.
  3. Multithreading: You can run hundreds of parallel data collection threads, reducing the time required to fully analyse a competitor’s catalogue from several days to a couple of hours.

Overcoming geo-restrictions and regional pricing

Many major retailers, airlines and international marketplaces actively use dynamic and regional pricing. The price of the same smartphone, flight ticket or set of car tyres can vary significantly across different cities and countries, depending on local demand, purchasing power and stock availability at a specific warehouse. Furthermore, websites often hide out-of-stock items or unique promotional offers from users located outside the target region.

Using proxy servers with precise geolocation allows businesses to overcome these limitations and view the market ‘through the eyes of a local buyer’. The analytics programme is configured so that data collection for each region is routed through strictly defined IP addresses.

A comprehensive approach to user simulation via proxies

To ensure monitoring remains 100% stable and undetectable by competitors, professional proxy solutions allow you to configure specific connection parameters for each region:

  1. Timezone alignment: The time on the server sending requests is synchronised with the timezone of the proxy server in the selected city.
  2. Language pack localisation (Accept-Language): Request headers are automatically adapted to the language of the target region.
  3. ISP spoofing: The ability to use IP addresses belonging to specific local internet service providers, which are automatically treated with the highest level of trust by marketplace security systems.

In this way, a finely tuned proxy infrastructure transforms aggressive automated scraping into discreet and legal collection of open commercial data, ensuring that companies receive accurate analytics without the risk of misinformation.

To automate data collection without being blocked, professional teams integrate custom proxies from the ProxyLine service into their systems. The service provides clean, dedicated IP addresses with HTTP(S)/SOCKS5 support and high speeds of up to 100 Mbps, which connect seamlessly to any market monitoring software via a convenient API. Using the ProxyLine infrastructure guarantees stable operation of parsers in multi-threaded mode and protects your analytical processes from data distortion by target websites.
