5 Common Web Scraping Pitfalls

Web scrapers face several difficulties because of the barriers set by data owners to restrict non-human access to their information. Here are the most common ones:

1. Bots

Websites are given the choice of allowing scrapers bots on their sites for web scraping purposes. But some sites actually do not like automated data scraping. This is primarily because some bots can be malicious and create security issues.


A type of website security measure, CAPTCHA (Completely Automated Public Turing to tell Computers and Humans Apart), is created to identify bots and decline their access to websites. Logical tasks or input of characters are displayed for verification, which allows distinguishing a person from a robot. A number of CAPTCHA solvers are implemented today in bots for repeated data collection, albeit it slows down the scraping process to some extent. 

3. IP Blocking

IP blocking is a common technique for stopping web scrapers from accessing a site’s data. Blocking is triggered if the server finds too many requests from the matching IP address or the search robot makes a large number of parallel requests. As a result, the site will either ban the IP fully or limit its access, breaking down the scraping process. This common pitfall may be managed if you learn how to cover your IP cope with. There are many approaches to try this and this article would possibly shed some mild on how to effectively cover an IP deal with.

4. Honeypot Traps

Site owners set honeypot traps on a page to catch scrapers. These traps are computer systems built to attract hackers and block them from accessing a site. The traps can be links that are not visible to people; however, scrapers can see them. If a scraper tries to obtain the content of a honeypot trap, it will enter a never-ending loop of requests and fail to retrieve further data.

5. Real-time Data Scraping

There is a range of instances where real-time data collection is essential, like price comparison, inventory tracking, etc. Due to the frequent change in data, scrapers need to monitor and obtain data at all times. However, as scrapers continuously monitor pages, it takes time to query and deliver data, and any variability can cause failures. 

Final Thoughts

Web scraping is now omnipresent in multiple industries and areas for better business progress. However, it demands considerable planning and careful execution, particularly if you are going into it on a reasonable scale. Simply by following some key best practices like learning how to hide IP addresses, you can handle all problems that occur during web scraping.
