Choosing proxy servers for scraping. Advantages and risks

Choosing Optimal Proxy Servers for Scraping

Identifying the most suitable proxy servers for scraping can be a complex task, given the variety of offerings from various providers. So how do we determine which proxy will be perfect for our project? In this material, we will discuss some aspects that will help you successfully carry out scraping.

Introduction to Web Scraping

Millions of data are available on the Internet. However, not all of this data is easily accessible. Professionals in the field of marketing understand the importance of data collection. Properly selected data play a critical role in achieving KPIs and goals. That's why marketers make every effort to collect the necessary information. This is where they get help from scrapers. Scrapers have become indispensable tools in data collection. With their help, you can thoroughly browse the website and extract information. Even large companies use web scrapers. Why then are others afraid of the term "web scraping"?

Advantages and Risks of Web Scraping

Web scraping is a controversial topic. As a result, some marketers do not risk incorporating it into their data collection strategy. But how can web scraping help a business achieve success?

Advantages

• Allows the business to keep up with current market trends and state of the market
• Helps track customer reviews, advertising placement, and overall market effectiveness
• Defines the appropriate product characteristics and prices
• Protects assets such as copyrights or trademarked materials
• Confirms domain distribution and geographical performance on the Internet

Potential Risks

• The website permanently blocks the IP address
• Legal consequences for tools, proxy servers, and their activities

The advantages of web scraping outweigh the potential risks. Those planning to engage in scraping can easily avoid these risks. How? Answer: by using proxy servers. They are an important element that helps scrapers succeed.

The Importance of Proxy Servers for Web Scraping

Proxy servers have a wide range of capabilities. Thanks to their universal functions, they can bring various benefits to any activity.

The primary function of proxy servers is to hide the location and source of the IP address. This allows users to send web requests without revealing their real information. The ability to change locations during surfing can help users access geo-restricted content. With this feature, users can collect information about the target audience without having to physically be in that region. This lets brands keep track of how they're performing in the target region. Understanding their market position, brands are refined as a whole. Proxy servers can access data that is completely forbidden. Since proxy servers can bypass content and geographical restrictions, they can easily access pages hidden from standard views.

Using proxy servers also helps to maximize scraper performance. This reduces the frequency of blockages. Without proxy servers, the effectiveness of web scraping is minimal. Proxies increase the "scan speed", which allows spiders to collect more data. Scan speed is the number of requests allowed over a certain period of time. This metric differs for each website.

Web requests passing through proxy servers come from different sources. Thus, they successfully overcome restrictions set by the website's anti-bot. Moreover, proxy servers help protect the user's original IP address. If a website identifies bot activity, the real IP address won't be blocked. Thanks to proxy servers, the likelihood of successful scraping increases.

Proxy Servers in Web Scraping

Proxy servers are an essential tool when extracting data from the internet. Despite the fact that web scrapers effectively collect information, their best performance is demonstrated in combination with a suitable proxy server.

Depending on the needs of your project, you can choose between private and public proxies. If your project requires high performance and maximum connection, private proxy servers will be most preferable. For smaller scale projects with limited finances, public proxy servers will be suitable.

Free proxy servers for web scraping are generally not recommended. In addition to lacking reliability guarantees, users can also expose their devices to the risk of malware infection. Moreover, they often become tools for illegal actions. This happens because free proxy servers are public.

Proxy Servers for Extracting Data from the Web

In addition to choosing proxy servers based on their exclusivity, users should also determine IP addresses of sources. Proxy servers are divided into three categories:

Data Center Proxy Servers

These are the most accessible proxies. Data center IP addresses are generated on standalone servers. Often these are the most practical proxy servers for data extraction. Thanks to their speed and competitiveness, users can effectively perform large web scraping projects. Additionally, these proxy servers don't cause legal issues regarding intellectual property acquisition. Unlike residential or mobile proxy servers, data center IP addresses do not belong to third parties.

Residential proxy servers

Residential proxy servers usually change, while provider proxies remain static. As they are associated with third parties, these proxy servers can be difficult to obtain. This situation makes their cost higher. In most cases, these proxies can give the same result as data center IP addresses. But data center proxies are much cheaper.

Mobile proxy servers

These proxy servers are the most difficult to obtain and the most expensive. They are perfect for use if a scraper needs to collect data available only on mobile devices.

Proxy servers for scanning Google and other sites

Almost any website can become a target for web scraping. That's why sites implement anti-bot systems. When these bots detect scraping, they immediately block the IP address. Depending on the server settings, it can block a specific IP address or the entire range of IP addresses. As mentioned above, proxy servers allow users to redirect requests to different sources. Thanks to this, websites see multiple users instead of one IP address source.

When choosing the best proxy server for scraping Google and other sites, take into account the number of API calls or requests you need. This number will dictate how large your proxy pool should be. The exclusivity of the proxy will also depend on the target site. If the target site requires a clean IP history, private proxy servers are the perfect choice. Proxies should also be compatible with your scanner or scraper. This will help you get the best results. In addition, each proxy should have a fast response time. Sites can easily detect a slow proxy.
