# YiLu Proxy in Web Scarping By [YiLu Socks5 Proxy](https://paragraph.com/@yilu-socks5-proxy-3) ยท 2022-10-19 --- **_Why choose YiLu proxy?_** [**YiLu Proxy**](https://yilu.us) provides more than **90 million** proxy IPs from **200+** countries and also supports switching one IP for one request, which is undoubtedly the best choice for **web scraping**. **_Why does web scarping need proxy?_** Recently years, the Internet industry is developing so rapidly, the time of big data has arrived peacefully. There is a huge requirement of getting data online and web data scraping has become popular and high efficient way to obtain network data. Most users will use a crawler to gain data with different proxy IP addresses to avoid being banned from the third platforms, such as Walmart, eBay, amazon and others. **_Multiple thread crawling_** In many cases, **web crawling** will run in a high-concurrency and multi-threaded mode, which means the amount of crawling tasks required is very large. So that will inevitably cause a large load on the site server, and the proxy IP needs to be used to help complete the task. Otherwise, it will be very easy to be detected and discovered by the crawled site server. **_Avoid Crawlers Being Banned_** When crawling data, crawler programs often need to make multiple high-frequency visits to the same site, and such visits are easily identified by the site server and have a high probability of being blocked. And under the help of different proxy IP addresses, the site server will regard that each visit comes from a different user to avoid the ban of the crawlers. **_Bypass the anti-crawl mechanism_** Most site servers have an **anti-crawling mechanism**, which will be triggered by repeated requests for access with the same IP. Therefore, it is necessary to bypass the anti-crawling mechanism of the site server through different proxy IPs.
