For many Internet workers, web crawler has long become an indispensable way to obtain data, but when crawlers are used to frequently crawl the same website, they are often banned by the website's IP anti-crawling mechanism. In order to solve the problem of banning IP is generally used in the following two ways:

1. Slow down the crawling speed and reduce the pressure on the target website, but it will reduce the data amount of crawling per unit time.

2. Because the URL you want to collect will block your request IP, your request cannot get the correct data. The proxy IP can play the role of the middle layer. After using the proxy IP, the crawler can disguise its real IP. Therefore, the ban cannot be implemented.

Of course, not all proxy IPs can play this role. Proxy IP is divided into two types: highly anonymous and transparent proxies; the transparent proxy IP server sees your real IP and proxy IP, and the high anonymous proxy IP server can only see the proxy IP. Therefore, it is also necessary to use a highly anonymous proxy IP.

In order to effectively break through the anti-crawling mechanism and continue to crawl at a high frequency, it is indispensable to use a high-quality proxy IP. So you can use MoMoproxy - the price is not expensive and the stability is much higher than the free proxy IP. MoMoProxy not only has a large amount of rotating residential proxies and datacenter proxies, but also can realize the rapid change of IP address. You can change the IP once per request, so helpful for your business.
