To avoid losing good data, you must be aware of the following mentioned 4 web scraping challenges and prepare yourself in advance.


1. Changing Website Formats


Web pages are structured in an interconnected manner. It is due to the diverse page design standards that can grasp as much information as possible within the compact form. These web pages are updated every other minute leading to a shift in their structural elements from time to time. Owing to this fact web crawling of these web pages can result in incomplete or unstructured data collection. Not all websites allow easy data access the web pages are flooded with sloppy codes of various kinds. Be it character encoding challenges or broken javaScript issues. Such problems can sabotage your scraper out of the blue.


When you own a web data extraction service providing company at a larger scale these problems arise without check. Always keep in your mind –


  1. Websites will change now and then
  2. Code issues will pop up more frequently than you’d like 
  3. Scrapers will be lost to either changing codes or broken elements

2. Bot Access, Captcha, and Traps

In anti-scraping technology, these factors make data collection even more difficult. Amazon and LinkedIn are popular examples that make use of sophisticated anti-bot measures to reduce intruders from scraping data. Some websites tend to refuse bot access, use an IP blockage mechanism to detect an unusual number of requests from any single IP address, while some others use CAPTCHA which can easily distinguish between a human and a scraper.


You will come across a few Honey-Pot pages during the data extraction process. These are straightaway traps that are set that no human will feel the need to access but a bot would. Since they can open all the links present within a web page. All you need is a scraper that can efficiently work around these preset boundaries. Try using Proxy IPs when scraping on a larger scale. Employ session management and IP rotation for a smooth web scraping experience. Implement a good blacklisting logic to avoid getting your bot from being blocked. Try not to use scriptable headless browsers to access web pages in excess. This is because JavaScript is used by many anti-scraper codes to separate humans from bots. Therefore, a scriptable headless browser will expose your web scraper.


3. Crawling Efficiency 


Once you encounter the above-mentioned two problems that means you deal in web scraping at scale. Now data efficiency can become the next roadblock in the process. While performing data extraction at such a larger scale it becomes essential to maintain optimal performance. In an ideal scenario, the crawling strategy must involve minimum manual effort. The scraper must be able to gather information within an estimated time frame without disrupting the quality of the data. To achieve such perfect results, distractions must be kept under constant notice like data extraction requests. Otherwise, the request cycle will increase and scraper performance will decrease. To enhance your crawler potential you must deploy your crawler across multiple servers instead of a single server. Make use of appropriate tools to extract data sets and eliminate any sort of data duplication. Reduce time for crawl stats metadata by optimizing database queries.


4. Data Quality

Data quality is the most crucial part of web scraping. It becomes challenging to maintain data quality maximum while gathering millions of data points a day. All collected data is within the unstructured format. It is also necessary to perform data conversion right after data collection. When data is obtained from several different sources it becomes vulnerable to impurities and complexities. However, manual monitoring solely is not enough to get 100% quality data as well. To detect duplicate entries, false entries, or inaccurate data we must use software tools. Data problems can range over –


  1. Falsified information being returned
  2. Volume-based problems 
  3. Inconsistent data types
  4. Ambiguity in data because of website changes 
  5. Junk data being accepted
  6. Data and product validation issues 


It is the responsibility of data analysts to ensure data quality is kept up to the mark. This can be achieved by performing data analysis when designing a web scraper bot. An automated system that can monitor data inflow to report any existing data inaccuracies. Note that developing such a system requires money as well as time. It is at times easier to delegate data extraction services to a third party. It proves useful in further breaking down business expenses.
