Professional scraping is impossible without the use of proxy servers, as most websites restrict or block mass scraper requests. Our tests have shown that no web server would send content to a crawler that sends high-frequency requests from a single computer.
In this article, we're going to take an in-depth look at how proxy servers work, the types and benefits of them, and how to choose a good free proxy for web scraping.
What's a proxy for web scraping?
A proxy is an intermediary server that routes requests from clients looking for resources to servers that provide those resources.
Because web scraping requires a large number of requests to a server from a single IP address, the server may detect too many requests and block that IP address to prevent further information collection.
This is why proxy servers are used to bypass blocking. They allow you to hide your real IP address and ensure that the server running the target site cannot detect your real physical location.

How web scraping proxies work
The primary function of web scraping proxies is to mask the scraper's true IP address, making it more difficult for websites to detect and block scraping activity. They:
- Mask the scraper's IP to avoid detection.
- Route the scraper's request through another IP.
- Fetch and return data to the scraper, bypassing IP-based restrictions.
This allows scrapers to access content without being banned, and to rotate IPs to further avoid detection.

Let's use a real-world analogy to explain how web scraping proxies work:
Imagine you want to check out the daily specials at a popular restaurant, but you've been there too many times in a short period of time, and the restaurant staff recognizes you. If they see you again, they might not let you in because they're suspicious about why you're visiting so often.
Without a proxy:
This is like trying to scrape a website without a proxy. If you make too many requests, the site will recognize you (by your IP address) and block you.
With a proxy:
Now imagine you ask a friend (let's call him Bob) to go to the restaurant for you and check out the daily specials. Bob goes in, gets the information, and reports back to you. The next day you send another friend (Alice) to do the same. The restaurant staff sees different people coming in each time, so they don't get suspicious.
In this analogy:
- You are the web scraper.
- The restaurant is the target website.
- Bob and Alice are the proxies.
- The daily specials are the data you want to scrape.
If you keep sending different friends (or proxies) to the restaurant (website), you can gather information without raising suspicion. This is essentially how web scraping proxies work: they help you access information without being detected or blocked.
Hopefully, this analogy clarifies the concept for those unfamiliar with web scraping and proxies.
Why do you need a proxy for web scraping?
You can't do web scraping without proxies on a large scale. And the main reason is that you won't get through the restrictions on multiple requests to a site from a single IP address without a proxy. When you refresh the page a certain number of times, the fraud protection system is triggered. Then the site starts to perceive your actions as a DDoS attack and blocks access to your pages.
Therefore, it is worth using several IPs at once to successfully collect information. But, of course, it all depends on how many requests you want to make.
Are web scraping proxies legal?
Scraping public data is legal. If the content is in the public domain and not copyrighted, it can be used legally. It doesn't depend on whether you use a proxy or not. However, the scraped data should be used within the law.

Web scraping proxy types
Residential proxies
A residential proxy is linked to a physical location via an Internet Service Provider (ISP) and is great for anonymous activities like streaming geo-restricted content or managing multiple social media accounts on Linkedin or Facebook.
Datacenter proxies
On the other hand, datacenter proxies are controlled by a hosting provider and are primarily used for large-scale data collection. These proxies are cheaper and faster than residential ones, but they're easily tracked and not as secure as residential IP addresses because the ISP can log your activity with them.
Mobile proxies
Mobile IPs belong to domains of mobile operators, and web developers avoid banning such IPs. Their fear is that each mobile IP can have tens of thousands of real users. However, not all proxy providers allocate mobile proxies to an individual package.
Rotating proxies
Rotating proxies mean that the proxy provider substitutes new IPs for an already open connection with a client at specified intervals. Sometimes even for every new request. This is a useful feature because you can get the content in two or three tries, even if the first request ends in an error.
It's worth noting that rotating proxies can be of two main types: datacenter and proxies. Each type has its advantages, and the choice often depends on the specific requirements of the task. For a comprehensive overview and a selection of the most effective options available, you can read a detailed review of rotating and residential proxies.
Forward proxies
Forward proxies stand for a proxy that acts as a courier and connects the client and web server independently to exchange messages. In addition to a forward proxy, there are reverse proxies with a subtle difference.
Reverse proxies
A reverse proxy refers to a server in a data center that intercepts all user requests directly to itself. The reverse proxy does not reach the external network itself but forwards the received client requests to the proxy servers in its local network. Having collected responses from the proxies to the external web server, the reverse proxy returns them to the client.
It can be said that from the client's point of view, a reverse proxy behaves the same way as a forward proxy. But, a different logic is used at the proxy level, whereby the server connected to the client never connects to the web servers on the external network.
Anonymous proxies
An anonymous proxy server does not pass your IP address to the website but identifies itself as a proxy. As a result, you maintain a certain level of anonymity as long as the website knows they are not getting your information. Because the website knows it is being accessed through a proxy, it may deny your request.
Dedicated proxies
Dedicated proxies are designed for a single user's exclusive use and guarantee maximum performance. Usually, they are used when other types of proxies become too slow due to many search attempts from numerous users or because the site is blocking all traffic from an abstract IP address range. In this case, private networking solutions come to the help with dedicated proxy networks like Personal Proxy Servers (PPS).
Shared Proxies
Shared proxies offer much cheaper access than personal or dedicated services but can be less reliable because you will share it with several other people as well as web crawlers and bots. Shared ISPs may also allow fewer concurrent connections at once than some of their competitors while offering lower speeds.
Which type of proxies is the best for web scraping
The primary choice of proxy type for scraping is between the datacenter and residential proxies. If you need high-speed and low-cost proxies, datacenter proxies are a good option. But if you need more reliable and anonymous proxies, residential proxies are the way to go. Additionally, the choice of proxy type may also depend on the specific requirements of your web scraping project.
Is a VPN or proxy better for web scraping?
The answer to this question really depends on the task. In most cases, a proxy is the best option for web scraping because it provides faster connections and more consistent performance than a VPN. However, if you need extra security or privacy while browsing, VPNs are an alternative solution.

9 Aspects to Consider When Selecting a Proxy Service
You might think that finding a good proxy service provider is very difficult. Especially when you consider the sheer number of providers on the market. So here are 9 most important factors to consider when choosing the right proxy service provider:
IP pool size
One of the criteria when choosing a proxy provider is the number of proxies available. This is especially relevant if you're working on a project that needs proxies from specific locations.
-
A small proxy pool means that they have a limited number of available IP addresses and may not meet your needs. Plus, a small pool of IP addresses is more prone to IP blocking.
-
A large proxy pool provides more specificity and a guarantee of access to a site by city or country. If you need to access sites in different locations, make sure that the proxy provider you choose has a great proxy pool management system.
Customer support
You may run into technical problems when working with proxies. Therefore, it is worth working with a provider who offers a good customer support system and who is willing to help you in a difficult time. They should also be ready to help you sort out the technical problem and its cause.
Reputation
A proxy provider that does not operate according to high ethical standards can expose you to significant security risks.
A proxy provider must adhere to an ethical code of privacy to ensure the safety of all its customers. The principles must comply with the General Data Protection Regulation (GDPR). Moreover, a reliable provider will require the device owner's consent before redirecting request data using his or her IP address.
Information collection
A proxy server must collect a minimum of information about you. Of course, all servers collect information about you, but paid and prestigious ones do it to a minimum. And they use it only for their own purposes. Without selling it or handing it over to government agencies.

Geolocation
When choosing a proxy, it is worth paying attention to the ability to select geolocation. Unfortunately, not all services support this feature, while it is one of the key parameters.
Depending on which country's proxy servers are selected, different resources may be displayed differently. For example, to view the Google search results for "Best cafes in New York," it is better to use a US proxy to see how it appears to users in that country.
Moreover, some resources may block access for specific countries. In such cases, if you are from that country, you will need to use a proxy to access the information.
Ability to choose the type of proxy
Different tasks require different types of proxies, and having the flexibility to choose can significantly enhance your online operations.
Response Time
Response time shows how fast the target resource responds when using a proxy. If the response time is very high, it is undesirable to use such proxies, as they reduce the speed and performance of the web scraping process.
Anonymity
The more anonymity, the better for your business. Before choosing a proxy provider, determine the level of anonymity you need. If it is high, make sure they offer anonymous and elite proxies that completely hide your IP address from all web resources.
Reliability
The reliability of a proxy depends on all the criteria mentioned above. The more parameters by which a proxy is secure and reliable, the higher the overall reliability of the proxy used. Also, pay attention to rotating proxies. This makes them better for automation and using in scraping tools.
