In web crawling and data scraping applications, efficiency is crucial. Sometimes, direct access may encounter many difficulties due to the anti-crawling strategy of the target website. 

At this point, using a rotating proxy ISP can be an effective solution to improve the efficiency of web crawling. This article will explore how to use rotating proxy ISPs to improve the efficiency of web scraping.

What is a rotating proxy

Rotating proxy is a way of using a proxy server where each connection is assigned a new IP address from the proxy pool. This means that users can send any number of requests to any number of sites through a script, and each request made will get a different IP address.

Rotating proxies help increase the level of web scraping, protect users from subnet bans, and also help users combine multiple tasks, such as social media account management or retail purchases

Why using a rotating proxy ISP can improve the efficiency of web scraping

During the network crawling process, various anti-crawling strategies are often encountered, such as detecting access frequency, limiting the number of IP accesses, etc. 

By using multiple proxy ISPs, we can simulate access from different IPs and reduce the risk of being identified by the target website.

In addition, different proxy ISPs may provide different network environments and access speeds. Using rotating proxy ISPs can improve the stability and efficiency of data crawling.

So, how to use rotating proxy ISP to improve the efficiency of web crawling?

Choose a reliable proxy ISP: Choosing a reputable and stable proxy ISP is the basis for improving web crawling efficiency. 

Make sure that the IP address provided by the proxy ISP is real and anonymous, and avoid using proxy servers from unknown sources to avoid legal risks or security issues. You can choose lunaproxy, which provides cheap and high-quality rotating ISP proxy, legal

Set a reasonable rotation strategy: When crawling data, you need to set a reasonable rotation strategy. For example, you can rotate based on factors such as the access speed and stability of the proxy ISP and the response time of the target website.

Adjust the crawling frequency and the number of concurrent connections: Reasonably adjust the crawling frequency and the number of concurrent connections based on the anti-crawling strategy and resource limitations of the target website. 

Using a rotating proxy ISP can better simulate the access behavior of normal users

Use professional web crawler tools: There are many professional web crawler tools on the market that support multiple proxy protocols and IP rotation functions. By using these tools, IP rotation can be performed more conveniently and the efficiency and stability of web crawling can be improved.

In summary, using a rotating proxy ISP can improve the efficiency of web crawling. By choosing a reliable proxy ISP, setting a reasonable rotation strategy, adjusting the crawling frequency and the number of concurrent connections, using professional web crawler tools, and complying with laws, regulations and ethics, we can perform data crawling work more efficiently.
