Real Estate Data Collection Solution: Multi-platform Listing Information Aggregation

Why do I need a proxy IP for real estate data collection?

Anyone who does real estate agents or data analysis knows that the biggest headache in trying to get real-time information about listings on multiple platforms is the platform's anti-crawl mechanism. Many websites will passIP Access Frequencyrespond in singingBehavioral characteristicsIdentify the crawler program, lightly restricting access, or directly banning the IP. e.g. if a platform finds that the same IP has requested 50 listing details within 1 hour, the protection mechanism will be triggered.

This is where proxy IPs become a central tool in solving the problem. This is accomplished byResidential Proxy IP Services from ipipgoIt can make each data request come from a different real home network environment. For example, the first time you visit with a Beijing IP, the second time you switch to a Shanghai IP, and the third time you change to a Guangzhou IP, so that the platform system will think that it is multiple real users browsing, which greatly reduces the risk of being banned.

How to choose the right proxy IP for real estate data collection?

There are many types of proxy IPs on the market, but real estate data collection has special needs:

In particular, note that some platforms will detect the IPdevice fingerprintrespond in singingnetwork environment. If you use data center IP (such as server room server IP), it is easy to be recognized as a robot. The real home broadband IP provided by ipipgo, together with the function of automatically changing browser fingerprints, can effectively simulate manual operation.

Four Steps to Build a Multi-Platform Capture Solution

Step 1: Characterize the target platform
First, organize the list of platforms to be collected, such as Shell, Chain Home, Anjuke, etc., and record their anti-crawl rules:

• Page load interval requirements (e.g., 3 seconds between visits)
• Hourly access limit for single IP
• Login authentication mechanism (whether an account is required)

Step 2: Configure proxy IP rotation policy
Set up IP switching rules in the ipipgo backend:

• Switching by request: changing IPs for every 5 pages collected
• Switching by time: IP change every 10 minutes
• Switching by anomaly detection: automatic switching when encountering CAPTCHA

Step 3: Simulate the trajectory of a real person
Add it to the capture script:

• Randomized sliding page dwell time (3-8 seconds)
• Simulate mouse trajectory
• Randomly switch User-Agent

Step 4: Data cleansing and de-duplication
Handle duplicate data with python's pandas library, with special attention:

• Differences in descriptions of the same property on different platforms
• Uniform conversion of price units (e.g., 10,000 yuan/m2 to yuan/m2)
• Image link validation

Frequently Asked Questions

Q: Why do I have to use a residential IP, can't I use a normal proxy?
A: Ordinary server room IPs have been focused on monitoring by major platforms. ipipgo's residential IPs come from real home networks, and the platforms are unable to recognize crawlers by IP type.

Q: How to choose between dynamic IP and static IP?
A: high-frequency collection with dynamic IP automatic rotation, need to maintain the login status of the task (such as the need to account for the site) with a static IP. ipipgo at the same time to support the two modes, can be switched at any time.

Q: What should I do if I encounter CAPTCHA frequently?
A: Open in the ipipgo consoleIntelligent switching modeIt can automatically change IP when CAPTCHA is detected, and it works better with coding platforms.

Why do you recommend ipipgo?

After testing several proxy providers, we found that ipipgo has three irreplaceable advantages in real estate data collection scenarios:

1. Precise geographic coverageIP positioning down to the district and county level, especially suited to the need for sub-division of regional house price comparisons
2. Highly secretive behavior: Native residential IP with HTTPS/SOCKS5 full protocol support, request header information without proxy features
3. Stability AssuranceExclusive IP quality monitoring system, automatically eliminating low-quality nodes, request success rate is maintained at 99.6% or above for a long time.

Recently, there was a typical case: a real estate analytics team used ipipgo to successfully implement theCollect 100,000+ listing data dailyThe IP blocking rate is reduced from 32% to 0.7%, and the data collection efficiency is improved by 20 times.
