Real Estate Data Collection|Real Estate Listing Data Collection Artifacts

Real estate agents get up in the middle of the night to see the collection of top tips

Recently, many friends who are real estate agents have complained to me, saying that it is now more difficult to find listing data than to find a date. The platform anti-creeper more and more ruthless, IP was blocked to the mother and father do not recognize. Don't worry, today I will teach you a set ofEven the platform engineers can't catch a break.The collection of the great law.

Why do traditional collection methods always flop?

Previously, an agency guy used his own home broadband to crawl data, and as a result, the entire neighborhood IP segment was blacked out the next day. Now the platforms are installedAI radar detector, can recognize these features:

1. The same IP visit too often (like swiping short video can not stop)

2. Repeated fingerprinting of equipment (like wearing the same clothes to a stakeout every day)

3. The pattern of operation is too obvious (start crawling at exactly 3:00 a.m.)

The right way to open a proxy IP

The last time I helped a chain of intermediaries to engage in data collection, they used ipipgo's dynamic residential agent, directly let the collection of the efficiency of 3 times. Remember theseknow-how to survive::

- Different city IPs for each visit (Shanghai today, Guangzhou tomorrow)

- Intervals between visits to look like a real person (randomly wait 3-8 seconds)

- Remember to clear cookies (same as throwing away the packaging after eating takeout)

Focusing on the dynamic IP pool, this thing is like theThe Monkey King who can change his faceThe pool of ipipgo automatically changes IP every 5 minutes, and the platform can't figure out the pattern at all. One client used this feature and collected for 15 days in a row without triggering an alert.

Teach you to build a collection system by hand

Take Python as an example of a three-step buildAnti-blocking Collector::

import requests
from ipipgo import ProxyPool The SDK for ipipgo is used here.

proxy = ProxyPool.get_proxy() Automatically get the latest IP address.
headers = {'User-Agent': 'Mozilla/5.0'} fake browser

resp = requests.get('listing link',
                   proxies={'http': proxy},
                   headers=headers,
                   timeout=10)

The key points are in these configurations:

- Called before each requestProxyPool.refresh()IP address change

- Don't set the timeout to more than 10 seconds (looks like a real life network card)

- Remember to switch User-Agents randomly (phone and computer for a change)

Frequently Asked Questions First Aid Kit

Q: What should I do if the collection is always redirected to the verification page?

A: eighty percent of the IP quality is not good, change ipipgo's high stash of residential agents, remember to bring the Referer parameter

Q: What should I do if the data is captured in a messy format?

A: use xpath with regular expressions double filtering, encounter dynamically loaded pages remember on selenium

Q: Will there be conflicts when collecting multiple platforms at the same time?

A: Assign independent IP segments to each platform, ipipgo supports IP pooling by platform, this feature is not available in many homes

Why do you recommend ipipgo?

Last time a customer used another proxy, the result of the IP recovery interval is too long, the platform was caught. ipipgo has three tricks.unique secret::
1. Residential IP ratio of 90% or more (exactly the same as real users)
2. Automatic anomaly detection (IP failures detected and switched in seconds)
3. Support for accurate positioning by city/operator (you can catch the data of any area you want)

Especially theirIntelligent Routing FunctionThe best export node can be matched automatically. Previously tested, with this feature collection speed can be as fast as 40%, the key is the stability of the peers hanging.

As a final reminder, follow the platform rules for collecting data. Using a proxy IP is like wearing a cloak of invisibility, but don't go wild in other people's territory. Reasonable control of frequency, good data de-emphasis, this is the long-term way. If you have technical problems, you can poke ipipgo's 24-hour customer service, and their engineers respond faster than a takeout boy.
