This article mainly introduces "what are the benefits of using proxy ip when crawling data information". In daily operations, I believe that many people have doubts about the benefits of using proxy ip when crawling data information. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation.

1. It is different to crawl data with a crawler.

For example, we can find some products to crawl data information every day, this data information is stored, as long as the commodity price changes, we can see very clearly, and the price adjustment is very good.

2. You can also refer to each other's commodity information, put new products on the shelves, and refer to the price range at the same time.

This is very useful for fledgling enterprises, and it is more helpful for our judgment to understand the information of the whole market.

The access to this information is not easy, because if you can get it at will, can you train your opponent? While the crawler obtains information, it will have a certain impact on the website server. For their own interests, enterprises are bound to protect their own data information, such as setting up various anti-crawler programs on the website to camouflage the data information. Take various ways to prevent you from obtaining effective data information.

3. The site will set up an IP detection line to detect the user's IP, which can adjust the user's access frequency and reduce the impact on the server.

Reduce the access frequency, so that even if the crawler uses the proxy IP to achieve a breakthrough, it can also increase the cost of the crawler, reduce the efficiency of the crawler, and the more timely the data information, the lower the effect, and the longer the crawler information, the more beneficial to the enterprise.

At this point, the study on "what are the benefits of using proxy ip when crawling data information" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
