The primary challenge in web scraping is not the denial of access to websites. Blocks usually occur in the form of specific errors or captchas.
Web scraping is an automated process, and some websites block the IP address from where the scraping activity starts. When you use proxies for web scraping, you reduce the chances of getting blocked.

How to scrape websites using proxies

You get blocked because the website is trying to identify or has already identified you as a scraping bot. There are ways you can bypass this anti-scraping technique, for example, the use of proxy servers.
When a site detects many requests from a single IP address, the site will quickly block the IP address. Proxy servers allow you to send your requests from multiple IP addresses and act as a middle man.
It retrieves data on the internet on the user’s behalf. It allows you to send data to other websites using different IP addresses while masking your actual IP address.
If you use a single IP set up in the proxy server, it is easy to get blocked. You need to create a pool of IP addresses and use them randomly to route your request through a series of different IP addresses.
Many servers can help to get rotated IP addresses, for example, VPNs. Web scraping tools make it easier to get IP address rotation.
