Scraping real estate websites is a critically important task for realtors, investors, and market analysts. Cian, Avito, CIAN, and other platforms actively block automated data collection using advanced anti-bot systems. Without properly configured proxies, your IP will be blocked after 50-100 requests, and you will lose access to valuable information about prices, listings, and market dynamics.
In this guide, you will learn how to choose suitable proxies for real estate scraping, set up IP address rotation, bypass the protection of major platforms, and collect data consistently without blocks and CAPTCHAs.
Why Real Estate Websites Block Scraping
Major real estate platforms — Cian, Avito, Yandex.Real Estate, CIAN — lose millions of rubles due to competitors and aggregators scraping their data. Therefore, they have implemented multi-layered protection against automated information collection.
Main methods of blocking scrapers:
- IP Address Limits: Cian blocks IPs after 80-120 requests per hour, Avito after 50-70 requests. This makes it impossible to collect large volumes of data from a single IP.
- Browser Fingerprinting: Websites analyze HTTP headers, User-Agent, screen resolution, installed fonts, and other parameters. If they appear suspicious (e.g., missing cookies or JavaScript), the request is blocked.
- Behavioral Analysis: Anti-bot systems track request speed, navigation patterns, mouse movements. Actions that are too fast or uniform raise suspicion.
- Cloudflare and Datadome: Many websites use advanced protection systems that check TLS fingerprints, WebGL, Canvas, and other technical browser parameters.
Without proxies, you will face blocking within minutes of active scraping. Your IP will be blacklisted for 24-48 hours, and you won’t even be able to open the website in a regular browser. For professional data collection, proxies are not an option but a requirement.
Real Example: A real estate agency in Moscow collected data on apartment prices from Cian for market analytics. Without proxies, their IP was blocked after collecting 200-300 listings (about 15 minutes of scraper operation). After implementing residential proxies with rotation every 10 minutes, they collect 50,000+ listings daily without a single block.
Which Types of Proxies Are Suitable for Collecting Real Estate Data
Three main types of proxies are used for real estate scraping. The choice depends on the scale of the task, budget, and the level of protection of the target website.
| Proxy Type | Advantages | Disadvantages | For Which Tasks |
|---|---|---|---|
| Residential Proxies | Real IPs of home users, maximum anonymity, minimal risk of blocks, bypassing Cloudflare | High price (from $7-15 per 1 GB), lower speed compared to datacenters | Scraping Cian, Avito, CIAN with high protection levels, collecting large volumes of data |
| Datacenter Proxies | High speed (up to 1 Gbps), low price ($1-3 per IP per month), stable connection | Easily identified by anti-bot systems, high risk of blocks on protected sites | Scraping small unprotected sites, testing scrapers, collecting data from APIs |
| Mobile Proxies | IPs of mobile operators (MTS, Beeline, MegaFon), hard to block, high trust from websites | Highest price ($50-150 per month per IP), dynamic IPs (change every 10-30 minutes) | Bypassing the toughest protection, scraping mobile versions of sites, critical tasks |
Recommendation for most tasks: For scraping Cian, Avito, and other major real estate platforms, the optimal choice is residential proxies. They provide a balance between cost, speed, and level of anonymity. Datacenter proxies are only suitable for small volumes or unprotected sites.
Residential vs Datacenter: What to Choose for Scraping
Let's break down in detail when to use each type of proxy for real estate scraping, with specific examples.
When to Use Residential Proxies
Residential proxies are IP addresses of real home users provided by internet service providers (Rostelecom, MTS, Beeline). To websites, they appear as regular visitors, making them virtually impossible to block.
Use residential proxies for:
- Scraping Cian: The toughest protection among Russian real estate websites. Blocks datacenters after 30-50 requests. With residential proxies, you can make 500-1000 requests from one IP without blocks.
- Scraping Avito: Uses Cloudflare and behavioral analysis. Residential proxies bypass TLS fingerprint and JavaScript challenge checks.
- Collecting large volumes of data: If you need to scrape 10,000+ listings daily, residential proxies are the only reliable option.
- Long-term projects: When scraping lasts for months, stability is crucial. Residential proxies rarely get blacklisted.
Example Setup for Cian:
Use a pool of 50-100 residential IPs with rotation every 5-10 minutes. Set a delay between requests of 2-5 seconds (random value). Emulate a real user: load images, execute JavaScript, send realistic User-Agent headers. With such settings, you can collect 20,000-30,000 listings per day without a single block.
When Datacenter Proxies Are Suitable
Datacenter proxies are IP addresses of servers in datacenters (Hetzner, OVH, DigitalOcean). They are 5-10 times cheaper than residential proxies but are easily identified by anti-bot systems due to IP range databases.
Use datacenters for:
- Scraping small regional websites: Local real estate agencies, bulletin boards without advanced protection.
- Testing the scraper: Debugging code, checking logic before launching on residential proxies.
- Scraping APIs: If the website provides an official API for partners, datacenters can handle the task.
- Limited budget: If you need to collect a small volume of data (1,000-2,000 listings) and are willing to risk blocks.
Important: Do not use datacenters for scraping Cian, Avito, Yandex.Real Estate. You will get your IP blocked within 10-15 minutes, wasting time and money. For these sites, residential proxies are the only working option.
Setting Up IP Address Rotation for Stable Scraping
IP rotation is the automatic switching of proxy servers at specific time intervals or after a certain number of requests. Properly configuring rotation is critically important to avoid blocks.
IP Address Rotation Strategies
There are three main rotation strategies, each suitable for different real estate scraping scenarios:
| Strategy | Description | When to Use | Settings |
|---|---|---|---|
| Time-Based Rotation | IP changes every N minutes (5, 10, 15 minutes) | Scraping Cian, Avito — sites with strict time limits |
Cian: 10-15 minutes Avito: 8-12 minutes CIAN: 5-10 minutes |
| Request-Based Rotation | IP changes after N requests (50, 100, 200 requests) | Sites with limits on the number of requests from one IP |
Cian: 80-100 requests Avito: 50-70 requests Regional sites: 200-500 requests |
| Per Request Rotation | Each request goes through a new IP from the pool | Maximum anonymity, collecting critical data | Requires a large pool of IPs (100+), high cost, suitable for particularly protected sites |
Recommendation for real estate scraping: Use a combined strategy — time-based rotation (10 minutes) AND request-based rotation (100 requests). The IP changes when either condition is met. This provides maximum protection against blocks.
Step-by-Step Rotation Setup in Popular Tools
Most modern scrapers and crawlers support automatic proxy rotation. Here’s how to set it up in popular tools:
Example of rotation setup (conceptually):
1. Create a list of proxies (file proxies.txt):
123.45.67.89:8000:username:password
234.56.78.90:8000:username:password
345.67.89.01:8000:username:password
2. Set rotation parameters:
- Rotation interval: 10 minutes
- Or after 100 requests
- Random delay between requests: 2-5 seconds
3. Enable real browser emulation:
- User-Agent: random from a list of popular browsers
- Accept-Language: ru-RU,ru;q=0.9,en;q=0.8
- Referer: the main page of the site or search engine
- Cookies: save between requests from one IP
Important nuances of rotation setup:
- Size of the proxy pool: For stable scraping of Cian, a pool of at least 20-30 IPs is needed. For Avito — 30-50 IPs. The larger the pool, the lower the load on each IP.
- Cookie retention: Do not reset cookies when changing IP — this looks suspicious. Each IP should have its own set of cookies, which is retained between requests.
- Proxy geolocation: For scraping regional listings, use proxies from the same city. For example, to collect real estate data in St. Petersburg — proxies with IPs from St. Petersburg.
- Functionality check: Before starting scraping, check all proxies for functionality. Remove blocked or slow IPs (ping > 500 ms) from the list.
How to Bypass Anti-Bot Systems of Cian, Avito, and CIAN
Modern real estate websites use multi-layered protection against bots. Proxies alone are not enough — you need to emulate the behavior of a real user. Let’s analyze how to bypass the protection of each major platform.
Bypassing Cian's Protection
Cian is the most protected real estate platform in Russia. It uses a combination of Cloudflare, its own anti-bot system, and machine learning to identify scrapers.
What Cian checks:
- TLS fingerprint: A unique fingerprint of the SSL/TLS connection. Cian identifies automated tools (Selenium, Puppeteer) by non-standard TLS parameters.
- JavaScript challenge: On the first visit, Cloudflare performs a JavaScript check. If the browser does not execute JS or does it incorrectly — block.
- Canvas and WebGL fingerprinting: Cian reads the unique fingerprint of the browser's graphics engine. Identical fingerprints from different IPs are a sign of a bot.
- Behavioral analysis: Scrolling speed, mouse movements, time on page, click patterns. Actions that are too fast or mechanical raise suspicion.
How to bypass Cian's protection:
- Use residential proxies: Only they can reliably bypass Cloudflare. Datacenters are blocked 90% of the time.
- Emulate a real browser: Use libraries that support a full browser (Playwright, Puppeteer Stealth). They emulate the TLS fingerprint, Canvas, WebGL of real Chrome/Firefox.
- Set delays: Between requests — 3-7 seconds (random value). Before clicking — 0.5-2 seconds. Simulate reading the listing — delay of 10-20 seconds on the listing page.
- User-Agent rotation: Use a list of real User-Agents from popular browsers (Chrome 120+, Firefox 121+, Safari 17+). Change User-Agent along with IP.
- Handle CAPTCHAs: Even with proxies, Cian may show a CAPTCHA with suspicious activity. Use CAPTCHA solving services (2Captcha, Anti-Captcha) or reduce scraping intensity.
Tip: For scraping Cian, we recommend using headless browsers with stealth mode (hiding signs of automation). Set random delays, emulate mouse movement, scrolling. Rotate IP every 10 minutes or 80-100 requests. With such settings, the success rate of scraping is 95-98%.
Bypassing Avito's Protection
Avito uses Cloudflare and its own bot detection system. The protection is slightly weaker than Cian's but still requires proper proxy settings and browser emulation.
Features of Avito's protection:
- Limit of 50-70 requests from IP: After exceeding the limit, Avito shows a CAPTCHA or temporarily blocks the IP for 1-2 hours.
- Referer check: Avito checks where the user came from. Absence of Referer or a suspicious source is a reason for blocking.
- Request speed analysis: If requests come in faster than 1-2 seconds — this is a clear sign of a bot.
- Regional binding: Avito checks the correspondence of the IP address to the selected city. If the IP is from Moscow but you're viewing listings from Vladivostok — this is suspicious.
Settings to bypass Avito's protection:
- Residential proxies from the required region: For scraping listings from Novosibirsk, use proxies with IPs from Novosibirsk or neighboring regions.
- Rotation every 8-12 minutes or 50 requests: Do not exceed the request limit from one IP.
- Correct Referer: Set the Referer as if you came from a Yandex or Google search:
https://yandex.ru/search/?text=buy apartment - Delay of 2-4 seconds between requests: Random value to avoid uniform intervals.
- Cookie and session retention: Avito tracks the user's session. Retain cookies between requests from one IP.
Bypassing CIAN and Other Platforms' Protection
CIAN, Yandex.Real Estate, Domofond, and other platforms have weaker protection compared to Cian and Avito. Basic settings are sufficient for them:
- Residential proxies with rotation every 15-20 minutes
- Delay of 1-3 seconds between requests
- Realistic User-Agent and basic headers
- Handling rare CAPTCHAs (appear in 5-10% of cases)
Tools for Real Estate Scraping with Proxy Support
For scraping real estate websites, both ready-made solutions and custom scrapers are used. The choice depends on technical skills, budget, and the scale of the task.
Ready-Made Scraping Services (No Programming)
If you are not a developer, use ready-made services with a visual interface and built-in proxy support:
- Octoparse: A visual scraper builder with drag-and-drop. Supports proxies, JavaScript, CAPTCHA. There are ready-made templates for popular sites. Starting at $75/month.
- ParseHub: Free tier for 200 pages, paid plans from $149/month. Proxy support, AJAX, infinite scroll. Suitable for scraping Avito and regional sites.
- Apify: A cloud platform for web scraping. Huge library of ready-made actors (scrapers) for different sites. Built-in proxy rotation. From $49/month.
- Bright Data (formerly Luminati): A professional solution with its own proxy network. Built-in tools for scraping, CAPTCHA bypass, browser emulation. From $500/month.
Recommendation: For beginners and small projects, Octoparse or ParseHub will suffice. For professional scraping of large volumes — Apify or Bright Data.
Libraries for Developers
If you are a developer or have a technical team, a custom scraper will provide maximum flexibility and control:
- Puppeteer / Playwright (JavaScript/Node.js): Headless browsers for scraping complex sites with JavaScript. Full emulation of a real browser, bypassing most anti-bot systems. Built-in proxy support.
- Selenium (Python, Java, C#): A classic tool for browser automation. Large community, many ready-made solutions. Requires additional libraries for stealth mode.
- Scrapy (Python): A powerful framework for scraping. Asynchronous, fast, scalable. Suitable for scraping simple sites without complex JavaScript. Easily integrates with proxies.
- BeautifulSoup + Requests (Python): A simple library for parsing HTML. Suitable for beginners and simple tasks. Does not work with JavaScript sites.
For scraping Cian and Avito, we recommend: Puppeteer Stealth or Playwright — they best bypass modern anti-bot systems due to full emulation of a real browser.
Practical Tips: How to Avoid Blocks
Let’s summarize all the recommendations in the form of a checklist for stable real estate scraping without blocks:
Real Estate Scraper Setup Checklist
✅ Proxy Selection:
- For Cian, Avito — only residential proxies
- Pool of at least 20-50 IPs to distribute the load
- Proxies from the required region (Moscow for Moscow listings)
- Check the functionality of all IPs before launching
✅ Rotation Setup:
- Time-based rotation: 10-15 minutes for Cian, 8-12 minutes for Avito
- Request-based rotation: 80-100 for Cian, 50-70 for Avito
- Cookie retention for each IP separately
- Random delays between requests: 2-5 seconds
✅ Browser Emulation:
- Use a headless browser with stealth mode
- Random User-Agent from a list of popular browsers
- Correct headers: Accept-Language, Referer, Accept-Encoding
- Execute JavaScript, load images
- Emulate scrolling and mouse movement (for Cian)
✅ Error Handling:
- Automatic CAPTCHA solving via 2Captcha or Anti-Captcha
- Retry on errors (maximum 3 attempts)
- Log blocked IPs and exclude them from the pool
- Monitor request success rate (should be > 95%)
✅ Performance Optimization:
- Parallel scraping: 3-5 threads with different IPs simultaneously
- Cache already collected listings (check by ID)
- Scrape during nighttime (less load on the site, fewer checks)
- Regularly update the proxy list (once a week)
Common Mistakes When Scraping Real Estate
Avoid these common mistakes that lead to blocks:
- Using free proxies: They are already blocked on 99% of websites, slow and unreliable. Saving on proxies will lead to wasted time and data.
- Requests that are too fast: A delay of less than 1 second between requests is a clear sign of a bot. Even with proxies, you will get blocked.
- Identical User-Agent for all IPs: If 50 different IPs use the same rare User-Agent — this is suspicious. Rotate User-Agent along with IP.
- Ignoring regional binding: Scraping listings from Yekaterinburg with an IP from Moscow looks strange. Use proxies from the required region.
- Not handling CAPTCHAs: Even with the right settings, CAPTCHAs may appear. Without automatic solving, the scraper will stop.
- Scraping during prime time: From 10:00 to 20:00, websites experience peak activity and maximum vigilance from anti-bot systems. Scrape at night or early in the morning.
Monitoring and Analytics of Scraping
Set up monitoring of key metrics to control the quality of scraping:
| Metric | Normal Value | Problem |
|---|---|---|
| Request Success Rate | > 95% | < 90% — problems with proxies or blocks |
| Average Response Time | 1-3 seconds | > 5 seconds — slow proxies, need replacement |
| CAPTCHA Frequency | < 5% | > 10% — too aggressive scraping, increase delays |
| Blocked IPs | < 2% of the pool | > 5% — problem with proxy quality or settings |
| Listings Collected per Hour | 500-2000 (depends on settings) | < 100 — too slow, optimize delays |
Regularly analyze the scraper logs, track blocked IPs, and optimize settings based on statistics. Scraping is not a "set it and forget it" process, but a continuous monitoring and improvement effort.
Conclusion
Scraping data about real estate from Cian, Avito, and other platforms is a complex task that requires the right choice of proxies, proper rotation setup, and emulation of real user behavior. Without quality proxies, stable collection of large volumes of data is impossible — your IP will be blocked within 10-15 minutes of operation.
Key takeaways from this guide:
- For scraping protected sites (Cian, Avito), use only residential proxies — datacenters are blocked 90% of the time
- Set up IP rotation every 10-15 minutes or 80-100 requests to distribute the load
- Emulate a real user: random delays, correct headers, execute JavaScript
- Use proxies from the required region for scraping regional listings
- Monitor scraping metrics and optimize settings based on statistics
If you plan to engage in professional real estate scraping or collect data for market analytics, we recommend trying residential proxies — they provide maximum anonymity, stability, and minimal risk of blocks. For tasks with particularly tough protection, mobile proxies with IPs from Russian operators are suitable.
Properly configuring proxies and scrapers will allow you to collect tens of thousands of listings daily, track price dynamics, analyze the real estate market, and make informed investment decisions — without blocks, CAPTCHAs, and data loss.
