Web crawlers play an important role in the era of big data. Whether it is data crawling, market research, or competitive analysis, it is inseparable from its application. However, one of the biggest challenges faced by crawlers during execution is being detected and blocked by the target website. Highly anonymous proxy IP has therefore become an important tool for web crawlers. This article will explore the three reasons for using highly anonymous proxy IP in web crawlers.

Reason 1: Improve privacy protection

Highly anonymous proxy IP can hide the real IP address, making crawler behavior more covert. Specific advantages include:

- Avoid IP blocking: Hide the real IP to prevent the crawler from being identified and blocked by the target website.

- Data crawling security: Improve the security of data crawling and protect privacy information from being leaked.

Reason 2: Disperse the source of requests

In web crawlers, frequent and concentrated requests are likely to attract the attention of the target website and trigger the anti-crawling mechanism. Using high-anonymity proxy IPs can effectively disperse the source of requests. The specific advantages include:

- Reduce the risk of being blocked: disperse the source of requests, simulate multiple users to access, and reduce the risk of being blocked.

- Improve data crawling efficiency: improve data crawling efficiency and reduce waiting time through multi-IP rotation.

Reason 3: Improve data crawling stability

High-anonymity proxy IPs usually have better stability and speed, ensuring that crawlers are not easily disconnected during data crawling. Specific advantages include:

- Stable connection: ensure the stability of the connection during long-term data crawling to avoid frequent disconnection.

- Quick response: improve data crawling speed, shorten the time to obtain data, and improve overall efficiency.
