Large-Scale Web Scraping

At first glance, web scraping may seem deceptively simple. There are many open-source libraries/frameworks, visual scraping tools, and data extraction tools that make it very easy to scrape data from a website. However, when you want to perform large-scale scraping of websites, everything becomes very complex very quickly.

Having a reliable proxy management system is very important if you want to reliably scrape web pages at scale and obtain location-specific data. Without a healthy and well-managed pool of proxy servers, your team will quickly find that it spends most of its time managing proxies and cannot scrape adequately at scale.

Here are 3 steps that will help you secure proxy management and ensure you get the data not only today but also in the future, in the long run.

1. Traffic Profile

To determine the specific needs of your project, you must first define the traffic profile. What is a traffic profile?

First of all, it includes the websites from which you are trying to obtain data. Also, if any technical issues need to be addressed, such as JS rendering.

The traffic profile also includes volume, i.e., how many requests you want or need to make per hour or per day. Additionally, are there any specific time frames for requests, for example, do you want all requests to be made only during business hours for some reason? Or can you retrieve data at night when traffic on the site is significantly less?

And the last part of the traffic profile is geolocation. Sometimes a website displays different content depending on where you are. Therefore, you need to use proxies that are located in the region you need.

Thus, these three elements together make up the traffic profile: websites, volume, and geolocation. Now, based on them, you can determine which specific proxy you need.

2. Proxy Pool

The next step for scaling is to create a pool of proxy servers. Based on the traffic profile, you can now estimate

1. How many proxy servers you will need
2. Where these proxies should be located
3. The type of proxy servers (data center or residential).

Access to proxies can be obtained directly from proxy providers, as well as through a proxy management solution. The disadvantage of obtaining proxies directly from providers rather than through a management solution is that you have to manage them yourself. When using a proxy provider that does not offer proxy management capabilities, there are many things to consider.

3. Proxy Management

The last step is proxy management. Having only a pool of proxies is not enough. You also need to use proxies efficiently. Here, for example, are some features of our intelligent proxy rotation network that allow you to manage proxies and maximize their value:

• Intelligent proxy rotation
• Automatic header management
• Geolocation according to your needs
• Session maintenance

Long-Term Scalability

First of all, proxy management should be a priority. Because if you are extracting data at scale, you will most likely not have problems with parsing HTML and writing a spider. But you will definitely have problems with proxies. That's why this should be a priority.

Then, if you manage your own proxies, it is important to keep the proxy pool clean and healthy. If you use a proper management service, this is not a problem because it does it for you.

And finally, a final note - be polite and respectful to websites. Ultimately, this is a very important factor when scaling a web scraping project. You should not hit websites too hard, and you need to make sure you follow the site's rules.

But again, if you use a management tool, it will be much easier to work with proxies, since everything will be done under the hood - you will only need to send requests and extract data.
