How to Fool CAPTCHAS While Scraping

Regardless of the industry you’re in, successful business strategies are built on a foundation of good information. Web scraping, when combined with a good rotating proxy server, gives you a fast, cost-effective way of carrying out your research. However, your web scraping software will encounter obstacles such as CAPTCHAS, which can interrupt your scraping activities. Is it possible to fool CAPTCHAS? Let’s look at our options.  

What is CAPTCHA?

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a test that distinguishes whether or not a user is human. It is often encountered by users logging onto a website or purchasing items online. It works by giving challenges that bots typically are unable to deal with, such as displaying random, distorted numbers or letters that humans can read.

Preventive measures

The key to fooling CAPTCHAS is to imitate human behavior to avoid attracting suspicion. For example, you can stagger your requests so the website thinks that it’s dealing with a human, since a person can’t send requests at the same rate as a bot. Another key is to frequently switch user agents. Because of the number of requests with large scale scraping projects, using the same user agent will eventually get you flagged.

Use a proxy server

Rotating proxy servers are great tools for enhancing your online security and anonymity by hiding your IP. A good rotating proxy server provides automatic IP rotation, which means your web scraping will appear more human. This fools the CAPTCHAS because you won’t have one IP address attracting unnecessary attention.

Integrate CAPTCHA solvers

Even with disciplined use of suitable techniques, there is still a good chance that you will encounter CAPTCHAS. At this point, you’ll need CAPTCHA solving services. And because you can integrate these solutions into your web scraping tools, they offer great convenience and efficiency. Moreover, these services are a reasonably priced option for large scale scraping projects. You need only look at the various options available and choose what’s right for you.   

Avoiding obstacles

Web scraping provides current information that can be used to grow your business. To avoid potential obstacles, practice good scraping etiquette so you won’t get blocked. A good rotating proxy server combined with your web scraping tool helps you scrape vast amounts of data efficiently, and that can make a world of difference.
