What is a proxy in web scraping?
Before you go and create your perfect proxy network, it's important to know what a proxy really means in web scraping terms? Once you know what it is, it will be obvious how it helps avoid the blocks.
Recall your networking class, an IP Address knows two things about you - your location and your Internet Service Provider. This is the reason why some over-the-top content providers can block certain content based on your geographical location. Voila, proxy!
A proxy is the invisibility cloak that hides your IP, so you can access the data seamlessly without getting blocked. When using a proxy, the website you are requesting no longer sees your IP address but the IP address of the proxy, giving you the ability to scrape the web with higher security.
Why is a proxy server used?
Going back to the video we watched earlier, a proxy server is the one who supplied this invisibility cloak to Harry. This intermediary server sits between you and the website. A proxy server assigns you a proxy, often from a pool of proxies, to seamlessly crawl the web. A proxy server handles your internet traffic on your behalf.
Why do you need proxies for web scraping?
Why is proxy the buzzword when it comes to web scraping? Well, scraping a well-designed and well-protected website at a medium to large scale could be quite challenging. The HTTP/HTTPS requests sent to the webserver can be blocked for various reasons. Remember the 4xx and 5xx status code responses you get while crawling the most visited e-commerce websites?
The most obvious reasons for these blocks could be
IP Geolocation: My favorite movie, The Lord of the Rings is not available on Netflix India. Now if the website recognizes you as someone trying to scrape content not available in your region or as a bot, they might not allow you to crawl their website to avoid overloading servers. If you really need that data for market research of your product or understanding how a new product feature is working in a particular region, you’d be in a real fix!
IP rate limitation- Almost every well-designed website has set certain limits on the number of requests they can allow from a single IP. Once you cross the threshold, you will get an error message and might even have to solve a Captcha so the website can distinguish between human and non-human activity. So beware before you send out thousands of requests to scrape an e-commerce website for your next price prediction campaign.

Ordinarily, anyone can see what you do online. When you connect to a non-secure website, advertisers, hackers, and government agencies can see where you’re located and what kind of computer you’re using. This information can be used to feed you targeted ads, and it can block you from seeing certain web content.
If you want to protect your privacy online, one of the simplest ways to do that is using a proxy server. Effectively, it serves as a gateway between you and the internet, so when using a proxy server the details of the websites you visit and other online history is saved to that server, rather than to your computer.
Here in this article, we’ve combed through existing reviews and tested some free proxy services for you. And from what we’ve found, these are 5 of the best free proxy servers out there:
1. GoingVPN - Going VPN offers a fast, reliable, high-speed, safe, and secure VPN that is totally free. According to their users, their lightning-fast connection and unlimited data for streaming and downloading can let you enjoy surfing without limit. Have the freedom to access all applications, websites, and services with their masked IP addresses on global server locations. Also, don’t forget that they’re easily available for all Android phones and tablets.
2. KProxy - KProxy is one of the most recommended free proxy servers. With KProxy, you have ten servers to choose from. You can manually pick from these and switch them anytime. So if you lose access to one server, you’re still protected. There are no imposed speed limits, as with some proxies. And KProxy has a good track record for avoiding detection and blocking by websites and ISPs.
3. Hidester - Recent user reviews have given Hidester a good reputation for reliability. But it’s not for sure that the reputation will stand up, because this proxy is pretty new. Its commitment to security extends to free users but paying customers receive access to literally hundreds of additional servers. Hidester also offers a number of free tools alongside its web proxy. These include a secure password generator and a DNS leak test. These could be major perks for users who want to stay safe online.
4. Megaproxy - Compared to some free proxies, Megaproxy’s servers are harder for snoopers to identify. It’s a convenient setup, and you can easily switch between regular and protected browsing. Unfortunately, this might be important with the free version. Megaproxy limits non-paying users to 60 site visits in a five-hour period. And it only encrypts 20 cookies at a time. Still, this adds a little extra privacy that not all free proxies have.
5. 4everproxy - Before connecting to 4everproxy, you can select both the server and the IP location. There are over ten options for the first selection and even more for the second. By trying different options you can find the perfect balance between security and connection speed. But speed shouldn’t be much of an issue in any case. Each of its server boasts a one gigabit per second connection. Each connection also comes with optional SSL encryption and blockage of cookies and scripts.
