Top 6 Best Services for Solving Captcha Issues in Web Scraping in 2023
If you have ever worked on a scraping project, you may have experienced the frustration of having your bot blocked by Captcha.
In our latest blog post, we will look at the top 5 services for solving Captcha issues for your web scraping project.
What is Captcha and how does it work?
The word Captcha stands for Completely Automated Public Turing test to tell Computers and Humans Apart. It is a tool that helps website owners distinguish computer-generated users from real users. The uniqueness of Captcha is that its test includes simple tests for humans.
However, for computer systems, these tests are somewhat more difficult. For example, a Captcha test may ask you to detect a certain area on the screen or identify numbers or letters, depending on what the system generates.
It should be noted that when dealing with such tests, the user must master three skills. These include the following:
- Invariant recognition: This is understanding of different forms, the same alphabet, images and objects.
- Segmentation: Involves understanding overlapping alphabets.
- Context parsing: Understanding sound or image as a whole.
- Math problems: A simple math question.
- Image recognition: Uses Google's Street View system and asks users to identify elements in it.
Less popular types include social media logins or invisible captchas. Despite their apparent simplicity, their application is quite diverse. Let's briefly look at how Captcha solving tools can help you.
How to avoid Captcha in web scraping?
Those who understand how Captcha works also know that it can be avoided when scraping the web. To do this, you need to understand how the Captcha system works and prevent it from being triggered. Below are some ways users can easily avoid Captcha.
Don't rush
The main reason users may encounter a Captcha test is exceeding the speed of operation. The Captcha system sees this as a red flag and asks the user to solve a Captcha. Therefore, the best way to avoid this is to work at a more human speed.
Use of proxy servers
Sites that are localized, i.e., available only to users in a certain geographic area, will expect traffic only from a local IP. Any other traffic coming from a non-native address will automatically raise suspicion, and sites usually show a captcha for verification. To prevent captcha from appearing in such cases, it is important to use geo-targeted proxies during scraping.
Traffic coming from data centers rather than residential addresses may also seem suspicious, and you may also see a captcha.
Avoid direct links
Most users go to websites via direct links rather than entering the URL. The Captcha system sees this as a problem and may consider it a red flag. Therefore, it is best to navigate to other pages of the site (which you are scraping) through the site's own navigation or using available referrer links.
Don't ignore honeypots
Honeypots usually exist in places invisible to the user. You can configure your bot to detect these elements and find the 'honeypot'. If your bot detects elements on the screen when they are hidden, there is a chance it will not react to that part of the page.
Nevertheless, the most effective way to solve this problem remains a Captcha solving tool. So we will look at the best Captcha solving tools available on the web.
