We live in an age where unlimited information can be accessed at the click of a button. Nevertheless, it’s not always as simple as that. Gathering large amounts of data without reliable proxy servers can easily put you on a website’s blacklist. This article shows you how to scrape websites safely and efficiently.
Use a proxy server
IP address detection is one of the most effective defenses used by websites to prevent scraping. And repeatedly using the same IP to scrape a site can get you blocked. A good proxy server can provide you with several IP addresses that rotate automatically, so you don’t need to worry about IP detection.
Slow down your requests
Websites can easily distinguish bot activity, since bots make requests a lot faster than any human is capable of. As a result, it’s a lot easier to detect bots and block your scraping activities. So, imitate human behavior, for example, by adding randomized intervals between your requests. This will slow down your requests and also prevent server overload.
Rotate User-Agent Request Headers
Implementing and rotating User-Agent request headers is a good practice that prevents blocking by making it harder for sites to detect that you’re scraping. Be sure to set a popular User-Agent request header and rotate it occasionally. A user agent is software that is acting on behalf of a computer user such as you. For example, a web browser implements the end user’s actions on web content.
Follow the rules
Stick to the laid-out guidelines. By adhering to the robots.txt file instructions, you can avoid getting on the site’s blacklist and being kicked off the server. Guidelines may include which pages can be scraped and how frequently you can scrape websites.
Scraping data doesn’t need to be complicated. With good processes, you can avoid getting blocked. The detection techniques that websites use will continue to improve, but so will scraping tools. And that’s why partnering with a good proxy server makes sense. Great service providers offer excellent features and support to scrape websites efficiently without hindrance.
