In their daily studies, many students use online tools such as quiz apps or learning platforms to enhance their learning. I have a friend who set up a pretest containing 100 questions while studying accounting. After completing the quiz, he wanted to extract the questions and answers for review and in-depth study. I recommended him to take the help of residential proxies, which can complete the data collection efficiently. I asked customer service for a deal to get 500MB of free traffic from Residential Proxies here and clicked on Residential Proxies to buy it and also get an internal discount.
Now I will share my help for my friend on the internet.
Reducing access limitations: For target websites, using residential proxies can better simulate access behavior and increase the pass rate of requests.
Large-scale data crawling: complete multi-page crawls, e.g. each question in a quiz application may be located on a separate page. Using residential proxies reduces the risk of trigger warnings associated with bulk access.
By doing so, you can not only extract questions and answers efficiently, but also save time in your study program.
Before formal data collection, it is very important to know whether the target website has a strict anti-climbing mechanism. Here are several ways to determine the restriction level of a website:
(1) Observe the access frequency restriction
You can try to quickly refresh the page several times to see if there will be a warning or the page loading slows down. If the page loading time increases significantly after frequent visits, there may be a frequency restriction.
(2) Analyze if the website uses advanced protection tools
Some websites use industry-recognized security protection tools (e.g. ReCaptcha, Cloudflare, etc.) to prevent non-human access. Check for the following features:
Validation boxes appear: for example, pop-up image validation or math problem solving.
Intermediate buffering on page load: some sites will say “Validating your request”.
(3) Check the robots.txt file
Most websites provide a robots.txt file in the root directory that describes their crawler access policy. For example, visit www.example.com/robots.txt可以看到是否限制某些路径的访问权限.
(4) Check for dynamic loading of page content
Some dynamically loading websites rely on JavaScript or Ajax for content rendering. The content of such websites usually requires more technical support to extract and is prone to triggering the anti-crawl mechanism.
(5) Search for user feedback or case studies
Many developer forums (e.g., Quora or StackOverflow) may have related discussions, and other users may have shared their experiences of crawling for certain learning platforms.
Step 1: Analyze the target platform
Confirm that each quiz question is independent of a single page.
Test whether the access frequency is significantly limited.
Step 2: Formulate crawling strategy
Step-by-step requests: Avoid sending a large number of requests at the same time and keep them within reasonable limits.
Interval time: Set a time interval between each request to simulate normal human behavior.
Step 3: Monitor and Adjust
If an increase in access failure rate is detected, adjust the request speed or change the residential proxies nodes to adapt the website anti-crawling mechanism.
1. Why choose Residential Proxies to optimize data collection?
The core value of residential proxies in learning related data collection is:Large-scale data crawling: complete multi-page crawls, e.g. each question in a quiz application may be located on a separate page. Using residential proxies reduces the risk of trigger warnings associated with bulk access.
