Web scraping allows quick extraction of data from several websites.
Several businesses use it for brand monitoring, data enrichment, lead generation, and for performing marketing analysis at scale.
However, it would be best to choose a proxy for web scraping to keep your identity safe and boost your network performance.
This article will discuss what proxies are, why you should select a proxy and the different types of scraping proxies to choose for your exact web scraping needs.
A Proxy is a type of server that acts as an intermediary between you and the internet.
All your internet browser requests are sent to the proxy server, which then forwards it to the requested address. Similarly, the requested data is sent to the proxy server, and the proxy forwards it back to you.
In simple words, you can think of proxy as a tunnel that acts as a gateway between you and the internet.
Web scraping is generally done using a tool known as the web scraping bot or scraper.
A scraper can browse a website a hundred times a day, leading to suspicious browsing activity that scraper detection tools, resulting in an IP ban.
Obviously, you do not want your web scraping bot to be detected by the information server.
Hence, it would be best to have a proxy server to keep your scraper anonymous because your original IP address remains hidden.
IP rotation of the crawler is needed to keep your scraper incognito. A proxy server helps you do that. Here are some of the top reasons for using a proxy for web scraping:
Now, let’s discuss the different types of proxies available for web scraping:
Datacenter proxies are not affiliated with any Internet Service Provider (ISP). These are the most commonly used proxies for web scraping because of their value for money and faster response times.
You also have the option to choose private datacenter proxies that are used by a single person at any time. Such proxies offer a significant boost in response times.
Datacenter proxies are suitable for business intelligence and competitor scraping because it generally involves working with many proxies.
Since datacenter proxies are cheaper, they offer the best solution for bulk scraping needs.
The risk of getting detected using a datacenter proxy is relatively less, but if you wish to zero in your chances, then residential IP proxy is the best fit for you.
Residential IP proxies come with legitimate IP addresses that won’t get you blacklisted from websites. In the case of a datacenter proxy, the website owners can detect that it belongs to a datacenter and not an ISP.
However, in the case of a residential IP proxy, the IP address belongs to an ISP. Hence, even if the website owner detects your IP, it will still look like a real person is browsing their website and not a scraper since the IP belongs to an ISP.
Static residential proxies are the best of all the proxies used for web scraping. It offers you complete anonymity using a static residential IP address and offers you blazing-fast speeds associated with datacenter proxies.
Hence, you can assume static residential proxies to be a combination of datacenter proxies and residential proxies. If you are engaged in scraping with a high chance of blacklist or IP ban, you should go with static residential proxies as it offers the highest anonymity levels.
A proxy pool is a system that controls the use of proxies. Web scraping requires you to work with several proxies since using a single IP address increases an IP ban’s risk.
The proxy pool manages your proxies set by rotating it intelligently so that your IP doesn’t get banned quickly.
Before you begin web scraping, it is recommended to keep your proxy pool ready. Regularly shifting your IPs makes it easier for you to concentrate on your work while making it harder for websites to track your IP.
Several proxy pool services offer you a variety of proxies to choose from. However, you should choose a proxy service that provides a pool of quality proxies like rotating residential proxies.
There are higher chances of IP blacklisting while scraping the web. Here are some of the best ways to prevent getting blacklisted while scraping:
