Purchase of datasets: Recommendations from legitimate data sources

First, looking for data is like buying food, the stall is clean or not is most important

Friends engaged in data analysis should understand that many of the channels on the market now called "first-hand data", just like the seafood in the market soaked in formalin, looking bright and shiny, the actual one touched on the accident. Last week, my friend's company was just fined 50,000 yuan, because of the use of unknown user behavior data, do you think this is unfair?

This is the time to use a proxy IP as a "silver needle to test the poison". For exampleipipgoThese are regular service providers who have IP pools that areClean resources with business filingsUnlike some wildcard platforms, the IPs are stolen from corporate broadband or hacked into home routes to get them. How to judge? Look at three points: whether there is a complete record of IP use, can provide data collection authorization, IP address is not from the regular room.

Second, proxy IP how to be a data bodyguard

Take a real case: an e-commerce company to catch the price of competitors, with the ordinary method just caught two days to be blocked. Switch toDynamic Residential Proxy for ipipgoAfter that, each request automatically switches real user IPs in different cities, and with their intelligent request interval settings, the data collection success rate directly soars from 40% to 92%.

Third, closed pit guide: these mines must not step on

1. When you see the "lowest price on the net", you can directly cut it away - the cost of serious IP resources is there, and the 99% which is lower than $1/GB on the market is a second-hand black IP.

2. Be wary of the ghost story of "permanent packages", IP resources have maintenance costs, and 80% of those who dare to sell permanent packages are ready to run away.

3. Remember when testingIP blacklistingTake.ipipgo backend IP health checker toolScan through and if more than 3 out of 10 IPs are flagged as commercial, change service providers quickly!

IV. QA time: what you might want to ask

Q: Is it illegal to collect data with a proxy IP?
A: Focus on whether the data source is open, such as collecting information from publicly available job boards, using theipipgo's commercially licensed IPAnd control the frequency of access, completely legal and compliant. But if you bypass login authentication to steal data, no god can save you

Q: Why is my agent always recognized by the website?
A: eighty percent is used in the data center IP, now the major sites are prevented from the server room IP. change to theipipgo's mixed dialing serviceThe identification rate can be reduced by up to 70% by randomly switching between residential IPs and dedicated corporate IPs.

Q: How many IPs do I need to use at the same time?
A: Don't believe the ones that tell you to buy tens of thousands of IPs for normal people with500-800 high quality IPs in rotationEnough. Focus on IP quality, IP pools like ipipgo areActive resources updated in real timeTwo hundred are worth 2,000.

V. Why specifically ipipgo

The most convincing thing about this brand to me is theirIP Traceability SystemThe IP authorization certificates can be found in every IP address. Last time we do financial data collection, the party must look at the IP authorization certificate, their customer service ten minutes to pull out the whole set of documents, even the operation and maintenance records of the server room have. Now on the market can do this kind of transparency, five fingers to count.

One more detail, their agent connection supportFingerprint Browser BindingThe same IP can simulate the network characteristics of different devices. The last time I helped a customer do APP data capture, with this feature directly bypassed the device fingerprint detection of a major manufacturer, than those who only change the IP proxy is too strong.
