How to Scrape Web Data at Scale With Proxies

Web scraping is when you extract data from publicly available websites. Companies are using this technique to be able to access structured data from the web. Nowadays data, and most importantly, information is something that people desperately need to drive their decision making.

As web data and web intelligence are becoming increasingly needed for businesses to succeed, it’s crucial to find the best technical solution for web scraping and crawling related problems. But what are these problems after all?

Why do you need proxies for web scraping?

Web scraping is easy when it’s simple, but it’s very difficult when it’s complicated. The hard part is not writing a piece of code to grab the data. You can easily do it after a little bit of practice, and coding skills. Of course, using a scraping library like Scrapy, Jsoup, or a headless browser like Puppeteer helps.

The hard part is to be able to make successful requests at scale. Because after a while you will need more data and you will need it more frequently. And if you’re not using proxies or not managing them correctly, you will not be able to get data. It becomes a question of how to find working proxies and how to manage them so they keep working long term.

Proxies can provide a solution to your special web scraping needs or when the website you’re targeting is simply unreachable without proxies. Generally speaking, there are three specific problems you can solve with proxies:

  • Different geo locations
  • Need for more data, more frequently
  • Get around anti-bot systems

You also need to manage them correctly to maximize their value. Without proper proxy management, you will just burn your proxy pool and eventually run out of proxies.

Web scraping at scale

When scraping the web at scale, you will come across a series of problems and challenges. You may need to make your requests from a specific location or country. Or you may want to work around anti-bot solutions.

Or simply want to make requests more frequently, to get data more frequently. Whichever the case, web scraping at scale is only possible if you use rotating proxies and make sure to be respectful and ethical with your scraper.


Be respectful and ethical

It’s very important to emphasize that when you are scraping you need to make your scrapers behave respectfully and ethically. Whether you’re using proxies or not, being nice to websites is critical for long term success. But let’s get specific, what you can do to be nice with your scraper:

  • Limit the number of requests you make
  • Adhere to the rules defined in robots.txt
  • Use high-quality proxies if you need scalability
  • Scrape when there’s less traffic hitting the website

If you follow these simple guidelines, you will have a higher chance of being able to extract data not just today but also in the future, while keeping data quality high. On the other hand, if you fail to be nice to the website, you can get in trouble and you will not be able to extract the data you need.
