Web Scraping with Proxies – The Basics You Should Know
We are moving at an exponential pace towards a data-driven world. Lightning-fast development of data analytics, availability of big data, and the improvement in computing power has led to the advent of data-driven strategies for business development. This is where web scraping with proxies comes into play.
This article covers the basics you should know about web scraping proxies and the benefits you can reap from it.
What is web scraping?
Web scraping is the technique used to extract a large amount of data from targeted websites, in order to gain insights for business, implement marketing strategies, plan SEO strategies, or simply understand the market competition.
What is a Proxy?
IP address: An IP address is a numerical address assigned to devices that connect to the internet. IP addresses give a unique identity to devices.
Proxy: A proxy acts as a layer between devices and the internet. Proxies are third party providers that route device requests to the internet through their servers. As a result of that, the proxy server IP address is visible to websites instead of the actual device IP.

Why use proxies for web scraping?
The benefits of using proxy services for web scraping can be drilled down to the following:
- Hiding your real source machine’s IP address.
- Getting past the rate limits that are set on the target website.
- Mining data from websites more reliably, thus reducing the chances of being blocked or banned.
- Making the requests from any geographical region or device, allowing you to scrape region-specific content.
- Making a high volume of requests to target websites & scrape data using a dedicated proxy pool without the fear of being banned.
- Saving you from blanket IP bans deployed by some websites. For example, AWS servers are commonly banned by websites, since these servers have a record of overloading websites with a huge number of requests.
- Allowing you to make unlimited concurrent sessions to the same or different websites.
What are the types of Proxies?
The most common type of proxies, datacenter proxies, offer IPs of servers housed in data centers. Datacenter proxies are private or personal proxies that are not associated with Internet Service Providers (ISPs). These types of IPs are cheap and can help build a robust web crawling solution.
