How To Use Proxies For Data Mining?
There are three kinds of proxies — residential, data center, and mobile. We need the first type for data gathering. Residential proxies are real devices you can connect to in order to route your traffic through a proxy gadget. By doing so, you will pick up the IP address of this device and cover your real one with it.
Then once you access the destination website, its servers will see the IP of a proxy, not your real one. And since residential proxies are real devices, you will appear as a resident of a certain location to a destination website — not as a person who is using proxies.
So if you apply a number of residential proxies to your scraper and set it up so that the bot changes IPs with every request, you can expect the data gathering to be smooth. The only thing to watch out for in this situation is the quality of proxies.
You can find free residential proxies, but we advise against using them. It’s not easy to manage the network of proxies, let alone obtaining residential IPs. So you can’t expect such a complex service to be free and high-quality. Quite likely, once you get those free proxies, you will see that most of them are blocked already.
Infatica offers affordable residential proxies that won’t be a burden for your budget. You can choose the number of IPs and locations you need — our pricing plans are flexible enough to fit any needs. And if you feel like none of the options we offer truly meet your requirements, just contact us so that we create a custom pricing plan for you. Easy as that! Our proxies are always ready to work with as we expand the pool of IPs constantly and replace blocked ones quickly.
